Building sustainably with recycled concrete

recycled concrete in Mashpee, MA

How does concrete recycling work

The preservation of natural resources is a real hot topic which concerns all areas of the economy of Massachusetts, of which the circular economy and better waste management practices now also plays an important role in the construction sector.

Good news: like many materials, concrete can also be treated and recycled while preserving its primary properties (durability, stability). However, although the use of recycled concrete helps conserve resources and this construction material can be used in the same way as traditional ready-mixed concretes, recycled concrete is not yet used on a large scale in construction projects. Learn more about the manufacturing, properties and potential of recyclable concrete!

Properties of recycled concrete

Recycled concrete meets the same requirements as traditional concrete. The strength, viscosity and quality correspond to those of concrete with natural aggregates, so that recycled concrete is just as easy to work with. Recycled concrete is available up to high strength, lower strength classes are approved for frost periods.

Overview of the main advantages of recycled concrete

The use of recycled concrete reduces the consumption of natural resources by almost 30%. The standard specifications for calls for tender for construction projects include options allowing the use of recycled concrete. All construction projects can be carried out with recycled concrete.

State standards limit it to 30% in structures (load-bearing elements, wall type), or even 20% for insurers. The possibility of increasing the authorized percentage is currently the subject of research.

The current standard authorizes the use of recycled aggregates for the formulation of concrete, specifying the conditions and limits of use. Aggregate producers have put in place quality assurance systems for their operational practices which make it possible to certify their production. This mark makes it possible to certify, through more rigorous controls and complementary tests that the aggregates comply with the standards for the general characteristics of the aggregates and with the standard for the mechanical and physical characteristics of aggregates.

The use of recycled concrete makes sense and makes an important contribution to the environmental protection of Massachusetts, provided that the transport distances of the recycled aggregates between the processing site and the concrete plant are not too long.

Where is recycled concrete used

According to the government, Massachusetts produces around 21 million tons of construction waste each year. Currently, only a fraction of this waste is recycled. The share of recycled aggregates is estimated at only 10% of total state aggregate production. Other states already produce structural concrete incorporating recycled aggregate. The state project has set itself the objective of making up for this delay and promoting the long-term reuse of all deconstructed concrete.

What are the obstacles and limits to the development of recycled concrete

Although reusing materials in an economical and environmentally friendly way allows for the use of fewer natural resources, recycled concrete is not yet very popular. There are several reasons for this, including:

  • Tenders for construction projects should be drafted accordingly, and while they include options for recycled concrete, they are generally focused on traditional concrete
  • Lack of guidelines or their insufficiency

Currently, there are still too few producers of recycled concrete in Massachusetts, so that there is not always production close to the site allowing short journeys. Technical knowledge about recycled concrete is not yet widespread enough. Reluctance exists in the construction sector.

How does concrete recycling work

Instead of natural gravel, prepared rubble is added as aggregate during the manufacture of recycled concrete, reducing the use of gravel from quarries and gravel pits by almost 30%.

In the Massachusetts region alone, around 4 million tons of construction waste are produced each year. If this waste were recycled, even in part, this would notably reduce the costs associated with their disposal. The use of recycled concrete can also significantly contribute to environmental protection by reducing the production of fresh concrete which requires significant extraction of limestone.

The prerequisite for recycling concrete is that the materials are sorted by type, so it is important to process them strictly separately from each other. In addition to classic masonry, tiles can also be recycled. If construction waste contains metal bars, pieces of wood or plastic, they are disposed of during the production process.

A special sieve in the bucket of a wheel loader separates the bricks or stones from leftover plaster, pieces of wood or plastic film, so that the rubble can then be crushed. Firstly, a hydro-chipping machine coarsely grinds the material before grinding it finely in the crusher to a particle size of 60 millimeters. A screening plant divides the crushed particles into aggregates of different diameters.

Mixed with water, cement and possibly other additives, the aggregate is transformed into a material that is easy to use and environmentally friendly: recycled concrete.

Why is the use of recycled concrete not yet very widespread in Massachusetts

1. Prejudices and ignorance

Recycled concrete is not yet very popular as some players in the construction sector also have reservations about the use of this material.

2. Lack of initial qualifications and continuing education in the manufacture, properties and use of recycled concrete

3. Regulated areas of use

Recycled concrete is limited to certain areas of application.

4. Absence of calls for tenders including the use of recycled concrete

Construction projects should be subject to product-neutral tendering to enable the use of recycled concrete. Currently, this is rarely the case, although it could be done without problem. Most calls for tenders only take into account fresh concrete.

5. Too few regional recyclers

So that recycled concrete can be used on a larger scale while being environmentally friendly, its production must take place in other states so that journeys to construction sites are as short as possible. This is currently not yet the case.

What are the advantages of recycled concrete

  • Less use of dumpster rental services
  • CO2 emissions lower than those generated by the production of fresh concrete
  • Prevention of mineral waste generated by the production of primary concrete
  • Preservation of resources, as fewer raw materials are extracted
  • Preservation of the landscape, fauna and flora
  • Properties and uses similar to those of traditional concrete

Recycling and recovery of polystyrene

sustainability in Minnesota

In our goal to reach zero waste, one concern is how to recycle plastic, in particular polystyrene.

Polystyrene is a material from petrochemicals. It is obtained through a polymerization process or by mixing gas and crystal. Polystyrene has become an indispensable material for factories and daily life, as it is frequently used to protect products. Moreover, although few consumers in Minnesota are aware of it, this material is also found in certain foods such as: strawberries, beans or beer. It is therefore entirely possible to recycle it for possible reuse.

Recycling polystyrene

Currently, the state of Minnesota continues to raise awareness among the population through sorting posters and pictograms which are proving effective. On the business side, they are also starting to schedule awareness training for their staff on the benefits of recycling polystyrene.

Here are the steps:

1st step: collecting the boxes

As its name suggests, this is the time to collect all household polystyrene waste.

2nd step: sending to a recycling center

This step consists of repatriating the waste to the factories using recycling bins and dumpster rentals. If the quantity of junk is too large, it is possible to use a densification press. There are all types and sizes on the market ranging from €100 to €10,000, depending on performance, in order to meet the needs of individuals and professionals.

3rd step: sorting

Now is the time to classify polystyrene based on its purity and quality. Please note that before being crushed, polystyrene is dissolved.

4th step: transformation

In order to give it a second life, polystyrene is first transformed into balls before re-entering the market as a material for manufacturing packaging, filling cushions, or even lightweight concrete. In the case of extruded polystyrene (a variant of polystyrene), this material is intended to become an insulating plate in the building.

Polystyrene recovery methods

According to Disposal St Paul Dumpster Rental HQ, a specialist in waste collection and recycling in xxx, there are 2 methods of recovering polystyrene:

Chemical recovery

This waste management method consists of destroying the polymer contained in the polystyrene in order to recover a few molecules of monomers or oligomers. Anything recovered from this chemical destruction will be synthesized again for reuse.

On the other hand, if a mixture of hydrocarbons is revealed instead of monomer, the latter must be treated using petrochemical techniques in order to find “classic” monomers. Unfortunately, chemical recovery is not an ecological solution, because it destroys the polymer chain.

Good to know: when the polymer is sufficiently heated – in the absence of oxygen – it decomposes and gives rise to various types of monomers and polymers. But the by-products obtained will be more difficult to assimilate into naphtha and will therefore become complex to handle.

Energy recovery

If oil has been used as fuel for decades, burning polystyrene allows you to find the same properties. Although the energy recovery of this material is not the best solution, it is still practical and economical for many families, especially since this type of recovery has contributed to the development of certain countries.

If the rudimentary incineration of the old days did not aim to revalorize polystyrene as energy, but simply to reduce its quantity, current energy revalorization requires equipment and technical knowledge. This is why machines are specially designed to transform the inherent calorific value of polystyrene into energy residual materials.

Zero Waste Unveiled: The Path to a Greener Future

Kannapolis zero waste

What is zero waste

Zero waste consists of reducing waste through simple actions.

Zero waste is a way of life which aims to fight against plastic pollution and more generally global warming while preserving our health. Getting started with zero waste is very simple: you just need to change some of your habits. Step by step, everyone goes at their own pace according to their expectations.

The advantages of a zero waste lifestyle

The advantages are numerous:

Preserve the environment: by eliminating plastic, removing single-use disposable items and favoring natural materials, reduing the need for dumpster rentals and durable and reusable products.

Fight against food waste: by only purchasing the quantity you consume.

Improve your health: by consuming more organic, more natural and healthy products. This lifestyle encourages a more varied and balanced diet composed of fresh, seasonal, unprocessed and plastic-free products. Thanks to this way of living, we can also save time and money:

Free up time: zero waste goes hand in hand with decluttering, once rid of the superfluous we are freed to take the time to live and devote ourselves to the essentials (leisure, time with family, friends, etc.). It also means stopping thinking about constantly buying disposable products as soon as they are finished since we have opted for products that are washable and reusable over time.

Savings: this lifestyle costs less because we refocus on the essentials (what we really need), we no longer run to stores looking for clothes or objects that we don’t necessarily need. It is also an opportunity to test second-hand purchases, upcycling, and DIY to produce products at lower costs. It also means saving on the food budget, most of the time, bulk products are cheaper because you do not pay for packaging and the initial packaging is larger and therefore more advantageous. Finally, we cook more, which costs less than buying “ready-made” food.

How to adopt zero waste in any situation

Zero waste is practiced both in the city and in the countryside, in houses and apartments. Each room is concerned: kitchen, bathroom, laundry room, bedrooms, toilet, dressing room, garden, etc.

But zero waste does not stop at the doorstep, it adapts to all situations and can also be practiced outside the home. There are therefore solutions adapted to each moment of daily life by applying the 5 rules also called the 5Rs.

At home

How to get started with zero waste at home?

At home, there are healthy and sustainable alternatives to conventional disposable products for every room in order to help reduce waste and eliminate plastic in everyday life.

Kitchen

The kitchen is one of the rooms in which we produce the most waste. The biggest waste is packaging and food waste. It is therefore advisable to eliminate disposable packaging by buying in bulk and then storing your food in jars. For food preservation, move away from plastic and aluminum to reusable beeswax packaging, organic linen flat covers or stainless steel boxes for healthy food preservation.

It also means getting rid of plastic kitchen utensils, which are often harmful to our health, by opting for durable wooden or stainless steel utensils.

Finally, you compost your food scraps either in a classic outdoor composter or in an indoor worm composter.

Groceries

To do your zero waste shopping, favor purchasing products in bulk, by the cut or in returnable containers. Remember to bring your bulk bags for dry foods and your empty pots. These foods can be found almost everywhere: at the market, in organic stores, in producers’ stores, in bulk grocery stores or even in neighborhood shops (bakeries, greengrocers, fishmongers, butchers, caterers, etc.).

At work

Zero waste can also be achieved in business as long as some good practices are put in place. Eliminate disposable cups for drinks and replace them with a reusable cup or mug for each employee or buy tea and coffee in bulk. It also means mastering the use of consumables (paper, pencils, etc.) and choosing them better. As an individual, everyone can bring about change by talking about zero waste in their business and by raising awareness among those around them.

What Dumpster Size Do I Need

Making the decision on what size dumpster to use is vital to the success of your cleanup job.

It is possible to incur more fees and/or delays in the removal of unwanted rubbish from your house or business if you rent a container that is too small.

Roll-off dumpster sizes are measured in cubic yards, and are often available in 10, 20, 30, and 40 yard sizes.

Some dumpster rental agencies have half-size dumpsters, such as 15-yard dumpsters, as well as tiny dumpsters ranging from two to eight yards in size.

The dumpster rental company or rubbish removal agency can assist you in determining which size dumpster is appropriate for your project.

We’ll go through the most typical dumpster sizes as well as the types of tasks that can be accommodated by each.

Jump to:

• 10 yard dumpsters
• 20 yard dumpsters
• 30 yard dumpsters
• 40 yard dumpsters

10 Yard Dumpsters

A ten-yard dumpster has a capacity of ten cubic yards

For a Ten yard dumpster, standard dimensions are 12 feet long by * 8 feet wide and 4 feet high, although these measurements may vary.

A 10 yard container will be sufficient for projects including the removal of waste from a garage cleanout, or small basement a 250 square feet deck, 1,500 square feet of roofing shingles, or a modest kitchen & bath renovation will be adequate.

20 Yard Dumpsters

A 20-yard dumpster has a capacity to hold 20 cubic yards of garbage

Its average proportions are 22 ft long x 8 ft wide x 4.5 ft high

A 20-yard container may be the most appropriate dumpster size for a garage, large basement, or attic cleanout project.

Furthermore, it may be the ideal size for flooring & carpet removal in bigger houses, deck removal of 300 to 400 square feet, and roof shingle removal of 2,500 to 3,000 square feet.

30 Yard Dumpsters

A Thirty yard dumpster holds Thirty cubic yards of rubbish and is typically 22 feet long, 8 feet wide, and 6 feet high.

Larger projects, such as a home extension, new home constructions, garage demolition, or the replacement of windows and siding on a medium-sized house may require a 30 yard dumpster.

40 Yard Dumpsters

In general, the dimensions of the forty yard dumpster are 22 feet long by 8 feet wide and 8 feet high, with a capacity of forty cubic yards of rubbish.

In some cases, a Forty yard dumpster may be the best option for a cleanup project including window and siding replacement on a huge house, commercial roofing jobs , new construction, and cleanouts, significant additions, or the disposal of large amounts of waste.

Remodelling A House

For the majority of home remodelling tasks, the 30yd dumpster is the most secure option. The sidewalls are high enough to contain heavier pieces of debris, & they are up for rent from the majority of dumpster rental businesses.

Residential Cleanout

A 20-yard container is ideal for residential cleanouts including flat buildings or single-family residences, among other things. They are compact enough to carry into most driveways while still being large enough to accommodate massive pieces of antique furniture.

Residential Construction

A 30 yard dumpster is generally required for residential construction projects in order to accommodate excess material trash. For long-term tasks such as demolition or the destruction of major residential complexes, you may have to upgrade to a Forty yard dumpster.

Commercial Construction

A 40-yard container is designed to accommodate the rubbish generated by large-scale building and demolition projects. While they are often too large to be used comfortably on residential homes, they are ideal for commercial projects where there is more space to work with than on residential premises.

Landscaping

Ten yard dumpsters are usually sufficient for most landscaping tasks because they generate a minimal amount of waste. If your project requires many buildings or modest constructions, you may have to choose a 20-yard dumpster rather than a 10-yard.

Roofing

Roofing debris is significantly heavier than you may expect. In order to prevent exceeding weight restrictions, it is preferable to rent a ten to twenty yard container for roofing projects that include slate, asphalt, or other heavy shingles, respectively.

Knowing what dumpster size will work best for your job will save you both time and money in the long run. Fortunately, renting a dumpster online or requesting an estimate to evaluate the finest options available in your area is an easy process.

Why So Much Plastic In The Oceans

Land-based pollution is the primary source of marine pollution. Commercial waste and domestic waste which blows into rivers and sewers then flows into the ocean is the major source of marine pollution.

Plastic pollution in the ocean comes from a variety of sources, including clothes. When we wash synthetic clothing in the washing machine, tiny “microplastics” are flushed down the drain. Using a dumpster near me when people have too much junk to discard is a ood way to help reduce pollution.

Each load of laundry can release up to 700.000 microplastic fibres, each less than a millimetre in length. Rather than being filtered, these end up washing into rivers and the ocean because they are too small. To What Extent Is Marine Life Being Harmed By Plastic Pollution? Is It Harmful To Humans?

The presence of plastics in the ocean has an impact on all marine life. Turtles think plastic bags are jellyfish, which they eat. Seabirds also think floating plastic is food, and they eat it too, which can lead to the death of many marine species.

Like dumpsters, whales also consume plastic. A whale showed up dead on a Scottish beach with 100 pounds of rope, plastic fishing nets, and other packing supplies in its stomach.

In addition, large nets and long ropes discarded in the ocean often trap & kill sea creatures because fishing types of equipment are designed to catch sea life. Around 300 critically endangered sea turtles could be found dead in Mexican waters after becoming entangled in the ghost fishing net.

Why Is It Necessary To Cut Single-Use Plastic?

We’ve seen the damage that single-use single-use plastics can harm marine life when they break down. life when they’re broken down. However, microplastics have a direct impact on human life. There is a strong correlation between the amount of plastic in the food chain and the number of microplastics in our bodies.

If you don’t consume seafood, you should be aware that microplastics in the air and water may have serious consequences for your health. Toxic hormone-disrupting chemicals known to affect reproduction, immune systems, and growth have been linked to the presence of microplastic particles in food.

Why Is The Ocean Becoming So Polluted With Trash?

If you’re serious about reducing the amount of single-use plastic in your daily life, you can start by reducing the amount of plastic you purchase.

Choose natural fibers, buy long-lasting clothing, learn how to mend & upcycle, & wash synthetic clothing with the whizzy microplastics guard like Cora Ball or guppy bag to avoid contributing to microplastic pollution from synthetic clothing.

We can avoid plastic pollution from harming sea life and humans alike by reducing our use of plastics and putting pressure on the government and plastic-producing companies to address the issue at its root.
What Is The Source Of Plastic Pollution In The Oceans?

Even if you live far from the coastal area, the plastic you discard has the potential to end up in the ocean. Plastic decomposes slowly in the ocean, resulting in microscopic fragments known as microplastics, which are extremely harmful to marine life. What does it mean when it says that 80 percent of the plastics in our ocean come from land-based sources? What’s the source of this?

There Are Three Primary Routes By Which The Plastic That We Use Daily Ends Up In The World’s Seas.

Not Recycling Plastic That Could Be Used Again

Putting plastic in the trash causes it to end up in a landfill. Plastic is frequently blown away during the transportation of garbage to landfills due to its lightweight. At this point, it can become clogged up around drains, which can then flow into rivers and the ocean.

Littering

In the end, litter that is dropped on the streets doesn’t stay there for very long. Rainwater and wind carry it into the water and through drains. It goes to the ocean through drains!

The illegal dumping of wastes is also a major contributor to the surge in plastic pollution in our oceans.

Things That Goes Down The Drain

Wet wipes, cotton buds, and sanitary products are just a few of the things that get flushed down the toilet regularly. When people wash clothes in a washing machine, microfibres are also released into waterways. Wastewater plants can’t remove them, and they end up in the food chain because they are too tiny to filter out.

Microbeads in rinse-off cosmetics and cleaning products have been banned by the UK government in recent months. This means that these tiny plastic beads won’t be washed down the sink and oceans, but many other things can also make the problem worse.

How Exactly Does Carbon Dioxide Cause Global Warming?

CO2’s Heat-Trapping Properties Are Unclear:

We all know that carbon dioxide or other greenhouse gases function like blankets or caps, trapping part of the heat that the Earth would otherwise radiate out into the universe. That’s all there is to it. But how can some molecules manage to capture heat in the first place? There’s a lot of physics and chemistry involved with that.

To put it simply, sunlight hits Earth’s surface and infrared waves radiate off of it, making us feel the heat. On a warm, sunny day, hold your palm over a darker rock to experience this effect for yourself. If these infrared radiation are allowed to pass through the atmosphere, they will return to space.

Infrared region in the atmosphere are unaffected by atmospheric oxygen or nitrogen. The reason for this, according to Smerdon, is that molecules are fussy about the wavelength ranges with which they interact. Energy that has wavelengths of roughly 200 micrometres or less is absorbed by oxygen and nitrogen while infrared energy has ranges of 700 to 1000 micrometres. It’s as if the infrared region don’t exist to oxygen and nitrogen; they can let waves (and heat) travel through the atmosphere without interference.

How Do I See This For Myself CO2 Is A Heat Trapper?

Fill one coke bottle with CO2 (also from a drinking fountain) and the other with ambient air as an inquiry that may be done at home or in the school, suggests Smerdon. A heat light will cause the CO2 bottle to warm up more than a bottle of ambient air, he explains. He advises using an infrared thermometer to verify the temperature of the bottles. Using the same design of bottle and ensuring that both jars receive the same quantity of lamp light are also important considerations.

Smerdon proposes putting a thermal sensor and a burning candle at opposite sides of a closed tube for a more difficult experiment. Camera clearly detects candle infrared heat when tube is packed with room air.. It is only after the tube is filled by carbon dioxide that an infrared picture of the flame fades, because CO2 in the tube collects and scatters heat from the candles in all direction, obscuring its appearance.

How Can We Be Sure That Water Isn’t To Blame For Environmental Issues If There Is More Water In The Atmosphere Than CO2?’

Water is, in fact, a contributor to global warming. As a result, it warms the globe by absorbing and emitting infrared light. Smerdon, on the other hand, claims that the increase in water vapour is a result of warmth rather than a cause.

A rise in global temperatures is caused by an increase in evaporation of water from the surface, which in turn elevates the temperature even more. Although a villain could try to increase global warming by pumping more water vapour into the atmosphere, Smerdon argues that this would not be possible. “It’d all rain out since temperature controls how much moisture the atmosphere can truly hold.”

Similarly, removing water vapour from the atmosphere is pointless because it will be replaced by natural evaporates from plants and water bodies due to temperature changes. By reducing these greenhouse gases, we can lower global temperatures and reduce the amount of water vapour in the air.

Fort Worth Dumpster Rentals

I am reporting a multitude of heath code violations for a Fort Worth suburban home I just visited. 

I am writing this reporting because neighbors have complained about a woman storing and collecting a large amount of items in her home. When I first got to the home I was shocked at the amount of stuff that had been accumulated in the home. 

I immediately knew it would take a roll off dumpster to collect all the things that had been accumulated.  The downstairs was bad but it seems like the upstairs was much much worse.  In her bedroom she had collected so many random things you could not even enter past the doorway. 

The entire upstairs was so packed full of stuff there was no way of moving around up there.  So I am assuming because of this the overflow of things started to make their way downstairs.  I have seen homes like this before but this one really took the cake because there was almost no room to move at all.

I told the woman that she had to get this stuff out of her home because it was a health hazard that put her and her neighbors at risk.  She was not happy with me at all but she knew what she had to do to keep her home. 

I witnessed her call a local dumpster rental company to come and deliver a roll off dumpster near me so that she could get started cleaning up.  I am going to check back in a week to make sure it is clean.

Proper disposal, collection, transportation, managing, and monitoring the waste materials are part of waste management. Proper waste management develops the nation or on local areas and maintain the cleanliness and order. Tidy place is pleasant to your eyes and help preventing negatives effect of debris that human produces. That is why dumpster rental service companies proliferate. Those companies help in proper waste disposal.

Proper disposal or waste management can give some benefits. Some of the waste can be converted to energy. This process is commonly called waste-to-energy or energy-from-waste. This is burning or boils the waste to generate and produce heat, steam or electricity.
Because you dispose you debris properly, it can be grouped into recyclable things. Separate items that can be recycle so that it easy to identify them. Examples of these are aluminum, copper, cans, wire, newspaper, magazines, equipment and etc.

They can be sold to the factories which use them as their products. You can also earn money from that exercise.
Through practicing proper waste management, it can help the environment to be sustainable and it minimizes the wastes with the help of recycling and resource recovery process.

Residents or citizens can rent a dumpster to handle debris from commercial or residential buildings before they can be properly collected. Dumpsters are containers used as storage for your debris. It may be small or large depending on the waste produced in the place. Separating the waste can also be a cool practice to keep the recyclable wastes for later use.

Boston waste management

The price on recyclables varies by market demand. The price in MA is down right now. We read that some recylers are “walking out” on their contracts to buy them from local collecting authorities because their warehouses are full. If you are a local and don’t buy that it’s the ‘city folks’ doing the dumping. Even the state road crews just dump their old culverts, etc. over a bank somewhere.

Don’t leave waste behind

By crassly consuming resources and leaving behind waste, we’re dumping the cost of restoration on them. The measure of our humanity is the degree to which we conserve Earth’s bounties for those who follow in our footsteps, while sparing them the burden of cleaning up our messes.
 
This whining gets to the heart of why The Times would run such a sloppy piece–out of sheer desperation. With up to 223 million North Americans now surfing the World Wide Web–where superb up-to-the-minute news and features are readily available–The Times and other newspapers stand to lose readership and clout, not to mention advertisers.

But for The Times to blame recycling laws for its inability to maintain a competitive edge in a fast-changing field is like Detroit auto makers crying that fuel-efficiency requirements keep them from competing effectively against the Japanese.

The fact is The Times, like auto makers and other industries, needs to find more efficient ways of producing its product, rather than demanding a licence to destroy the environment in pursuit of profit.

Can you tell me about cities (in the US, primarily) that have taken steps to promote or encourage recycling of mixed office paper (or any office paper) by office buildings (multi or single tenant) in their jurisdiction? I am asking on behalf of the City & County of San Francisco, a very office-intensive town, which is trying to raise its recycling rate to the neighborhood of 50% in the foreseeable future.

Actual recycling programs

We’d like to get in touch with people who have been involved with both the outreach to businesses and the actual recycling programs, to see if an approach can be well adapted for Boston.

The city has strong programs, both public-sector and private-sector, in place for high-grade paper and newspaper; and commercial recycling companies serve many of the area’s big businesses, for those grades of paper and the mixed office waste papers using Boston dumpster rental services; but what can local gov’t do to promote these efforts further, help them grow into “lower” grades of paper, and increase the customer base?

What’s been done in your town? Who can we talk to to learn more about it? We will check on this message daily. Feel free to respond here or email, and thanks in advance.

Scavenging and junk buying have frequently appeared in development literature as symbols of urban environmental deterioration, human degradation and lost hopes.

Beyond these images, however, lies a reality in which these disparaged occupations provide refuge for the unemployed, a secure economic niche for particular ethnic, caste, or territorial communities, material inputs for local industries, commodities for export, and a means of diverting large amounts of recoverable materials from landfills and composting plants.

While the social and economic arrangements that provide the structure of these occupations differ in their particulars from city to city, some general characteristics are evident across their occurrence.

Recycling Business in 2020

waste

It is estimated that by the year 2025 there will be 900 million surplus computers and monitors in the US. These computers and monitors contain hazardous materials, and are destined for our landfills, which can pollute the environment. This is a very serious waste management concerns all over the world, with electronics filling dumpsters everywhere.

Waste management in electronics

However, many states have passed legislation to ban monitors from landfill. The computer-recycling infrastructure in just beginning. Get on the ground floor and build your computer recycling business or non-profit training program now! Learn the secrets of where the grants and money is to start your operation.
 
California passed the Electronics Waste Recycling Act of 2003 (SB 20) the first of its kind of legislation in the nation to address the growing electronics waste problem. Authorized collectors and recyclers of monitors may be reimbursed for expenses for collecting and recycling monitors from the Electronics Waste Recovery and Recycling Account portion of this legislation after July, 2004 in California. This account is expected to be in the tens of $$millions of dollars.
 
You do not have to be a California Business to participate. California generally leads the nation on innovative programs and trends. The EPA, environmentalist, computer manufacturers, waste industry, state government and local government are looking at the California model.

Our book Computer Recycling For Education will assist you in setting up your computer recycling business or training program. This book is ideal for recyclers, jurisdictions, municipalities, waste haulers, refurbishers, nonprofits or school computer repair training programs. It may also be used as a reference for college environmental studies departments.

Solar energy to the rescue

You can power your house with 2000 peak watts of used ARCO panels. The only effect from the concentrators was out gassing from adhesives that condensed on the inside of the glass, reducing output. The price of these panels reflects the abuse they have received, and they are the lowest cost per peak watt PV panels available. We would not recommend these panels in cloudy areas like the Pacific NW, as they are not great performers in overcast weather.
 
Ultimately add a dozen new panels on a two axis tracker to help power an electric car and get a bit more power in winter/cloudy weather. Out of the sun, if possible. The encapsulate will deteriorate a bit faster if they aren’t making power, because they’ll be hotter. will sell you either their Alternative Energy Source book, which has a good deal of information on system design and component selection, but not much on actually wiring it, or The New Solar Electric Home which has much more detail on design and installation, but not much on specific vendors.
 
In either case you probably shouldn’t do it yourself unless you know at least the basics about power wiring or did an undergraduate thesis project on some aspect regarding solar panels.

Uses for motors connected straight to solar panels, or motors connected to batteries charged by solar panels, or any other uses. There are ways to get maximum power out of solar panels. For example – various sun-tracking systems, the use of motorized mirrors.

The solar part of the system (at least the panels anyway) are guaranteed for 20 years. That’s a bit more than $100 a year. Not that bad. If your generator doesn’t last 6 years, it would cost more than that per year (plus gas and maintenance costs).

First, calculate how long you might expect my batteries to last. Without trying to determine exactly how much power I would be using, your daily average can be 25 amps. This means that a dual 6-volt system with 220 amp-hours of capacity, taken down to 50% (or 110 amp-hours available) would last 4 days with a bit of reserve (or allowance for not being fully charged). Next, determine the number of days you want to be able to dry camp.

Cost breakdown 

They are big and heavy (120# each) but the cost difference ($180 each for the 220s and $220 each for the 395s) isn’t all that much for almost doubling the capacity.

In the Backwoods catalog there is a 64 watt panel. 4 of these would produce 256 watts. If you were always in a sunny location or using the system in certain other areas of the country you could get by with as little as one panel. These panels cost $350 each. These particular ones don’t use glass but unbreakable plastic and are thus lighter. Both good features for RV use. 4 of them will cost $1400.
 
Now you need mounts to put the panels on. 2 portable mounts (each will hold 2 panels) comes to $170. #You’ll need some module interconnect wiring to go to the combiner box. Let’s say 5′ for each module should do it. 20 feet costs $15. You now need a weather-rite combiner box to take the small gauge wire from the 4 panels and combine them to a much larger gauge wire. This box costs $115.

Next you need the large gauge wire to run from the location of the panels and combiner box to the charge controller in the pop-up. Figure on 50′ to give me a good chance of finding a sunny spot. For this distance you need 2 strands of 4 gauge copper with UV resistant jacket. Lets say it is $100. Next you need the charge control unit itself. You want a pretty good one with some meters and 3-stage charging.
 
There are just too many variables to be specific. Therefore generalities are very useful. There are more than a few people here that have moved on. Who said anything about 120v power. This discussion is about battery consumption and that is 12 volts. Besides, if you thought about it you would have realized we couldn’t have meant 60 amps of 120 since the most that RV parks offer is 50 amps.

Battery life

No, its not standard practice and it will effect the life of the battery. The system design has to take this into account. Sometimes it is necessary to use up most, or all, of our battery depending on the availability of sunlight due to weather, or camping in a cave and a deep cycle battery can do this without serious damage. Naturally, if you do it a lot, it will shorten the life effect on the battery life, but you can certainly do it.
 
A ‘shallow cycle” car battery is not designed to go to complete discharge, whereas the deep cycle product uses thicker plates which allows it to be depleted without killing it off. That is why a deep cycle battery is rated in amp hours, and a car battery is rated at CCA or some other version of quick discharge, cranking amps. If you have a 100AH deep cycle battery, you CAN draw 20 amps for 5 hours.
 
A car battery will not deliver this. Trojan and others provide data which will show you the life you can expect based on how many times you cycle the battery all the way down, or how many times you can go to 50%, or whatever you plan to do.

It is good practice not to run them down too far, but the capacity is there if you want it, and most applications will require that this happen more than a few times over the life of the battery, especially for camping when you don’t want, or need, a huge battery bank and a ton of solar panels. Its just a matter of using the technology that is available to provide for a specific need.

You bought it, but you didn’t check the MTBF. If you contact the manufacturer’s website, you can get that information. If you know how long your car or trailer should last, why not the same for a generator?

Honda are pretty good generators, but you might not like what you find out. That is $2100 dollars for 3 generators, assuming the price doesn’t go up in the future. We can count on an increase if you can use solar, you only buy it once. That would be the better investment, if you can use solar.

If the generator is a 1000 watt device, and if you run the battery charger from the 120V output, you can only achieve 8.3 amps per hour, not 20. We wouldn’t expect that the 12 volt output is 20 amps, probably closer to 10, but we don’t know your generator specs for certain. If you want 20 amps at 120v, you need a 2.5 killowatt generator. Running a deep cycle battery flat is what they are made for. You can zero the trojan ones out at least 100 times. That is why they are known as deep cycle batteries.  

Not everyone can make use of solar. If you buy solar equipment from an RV catalog. you will pay a lot of money for it, just like everything else they tend to sell. When you shopped for your trailer, you didn’t just buy from some catalog without investigating prices and looking for a good deal. After searching, you probably got a pretty good deal. Why just see prices on solar in an RV catalog, of all places, and determine that its too expensive? 15 amps of what power? What is the wattage of the furnace fan?
 
Is it 12V? how long does it run on a cool night. Its not on all the time, so saying 15 amps doesn’t provide any information about the power requirements. Not everyone can use solar, but those who are candidates should not be discouraged from checking on the possibilities. If you want to run a furnace or an air conditioner all the time, go for it, but you may not get there from solar.

You will never know if you don’t know the power requirements of the devices you want to run. When dry camping, plug the 110 volt cord from your trailer into a PROwatt 800 inverter in our van, turn OFF the converter in the trailer, and supply 12 volts to the trailer directly from a deep cycle battery in the van via the “charging line” in the umbilical cord between van and trailer.
 
Based on dry camping experiences, including two 6-day sessions last summer, we concluded that we can dry camp indefinitely, provided that we run our van’s engine an average of at least 1.5 hours per day to keep the house battery charged. We normally have no problem at all doing this, simply driving around for local sightseeing and running errands.
 
The custom “rv type” electrical system includes a 210 amp-hour 4D deep cycle AGM battery by Lifeline, a PROwatt 800 modified sine wave (MSW) inverter by Statpower, a 3-stage 10-amp charger by Statpower, and a PORTAWATTZ 300 MSW inverter (also Statpower) to power the 10-amp charger during most normal and long distance driving.

Better waste management

If your battery is rated 70 amp hours, then 10 amps is much more than a trickle charge. Without defining the system requirements, there is not point in making statements about what is a trickle charge, what is a reservoir, and “solar is not any good”.

Every application is different. Those generators cannot deliver much more than the “trickle charge” . With such a limited MTBF, you will buy an awful lot of generators over the life of your camper.
 
The average RV user will get a lot more out of a solar setup than from a generator. Its quieter, its infinitely more reliable than a generator, it won’t irritate your neighbors in the campground, and it doesn’t need gasoline at $3 a gallon. A pair of T-105 Trojans, fully charged, can deliver over 2 kilowattts before discharging completely. A lot of folks won’t use that much in three or four days of camping, especially in the world of pop-ups.


 
Solar is a great benefit to the camping world.

Determine the requirements for your application. Yours will be different than any one else’s. What are the cheapest solar panels available, and from who, or does any one know how to make home made solar panels that would still generate electricity, but for a lot less $ per watt.

Solar panels are pretty hard to make. The process involves several chemical mixtures and lot of weird stuff. You can to put together a small 12 Volt DC battery charger for about $75. These little panels can charge a car battery.
 
Unless you have a physics lab-from-hell, you cannot make your own solar panels. They are made from thin slices of pure crystals of some pretty esoteric materials.

What Is Sustainable Development?

Development that satisfies the requirements of the present while without sacrificing the potential of succeeding generations to fulfill the necessities is called sustainable development. “

Although the term “sustainable development” can be defined in a variety of ways, it refers to a strategy for growth that takes into account our society’s environmental, social, and economic constraints while also balancing competing needs.

Too often, development was driven by a single need without taking into account the broader or longer-term consequences. Our reliance on fossil fuel-based power sources is already changing the climate of the world, and we’re already seeing the devastation that may result from this kind of approach. As time passes and we continue on our path of ecological degradation, the more often and terrible the repercussions will be.

Is The Environment The Only Consideration?

One of the foundational tenets of sustainable development is limiting our impact on the environment. Climate change is a possible consequence of not doing so.

Sustainable development, on the other hand, goes far beyond environmental concerns. Furthermore, a strong, healthy, and just society must be ensured. There must be a focus on serving the needs of everyone living in both current and future communities, fostering a sense of community, and ensuring equal opportunity for everyone.

If Sustainable Development Priorities The Future, Do We Have To Give Up On The Present In Order To Benefit From It?

The answer is no. Finding better ways to do things now and in the future is what sustainable development is all about. Even if we have to make some adjustments to the way we live and work right now, our standard of living won’t suffer as a result.

In the short and medium term, sustainable development can bring various advantages, such as:

Savings – The administration has saved approximately £60 million by improving its efficiency along its estate as a consequence of SDC inspection.

Walking or cycling short distances can save you money, enhance your health, and be just as quick and handy as driving.

Is It Affecting Me In Any Way?

Everyone is impacted by the method we take to development. People’s lives are directly impacted by the decisions we make as a society. Poor community design, for example, lowers the standard of living for its residents. Food shortages could occur if the United Kingdom relies on imported food rather than domestically grown produce.

In order to make better judgments about the challenges that touch us all, sustainable development gives a framework for doing so. We can ensure that people have access to health and recreational amenities by incorporating healthcare plans into the design of new communities. To ensure that the United Kingdom has enough food for such long term future, we need to encourage more sustainable food systems.

The Question Is, How Do We Get There?

All of us have a role to perform in this world. Taking a few small steps can make a big difference when taken together. However, we feel that the Government must take the lead in order to be sustainable in the United Kingdom. That’s what we do at SDC, and we do it through a combination of review and advise as well as the creation of organisational capacity for long-term growth and development.
