1 recycling Energy and waste management

2 Types of recycling  Closed loop recycling: plastic bottles becoming new plastic bottles; when the material collected is recycled into new material of the same type. Common with aluminum cans becoming new aluminum cans

5  Open loop recycling: normally when products are recycled into different materials: plastic bottles being downcycled into plastic tubing, pipes or polyester fiber to make clothes..

7 Recycling and energy saving  Recycling is a way to save energy in manufacturing new consumer goods.

8 One of the most efficient forms of recycling is aluminum recycling. Aluminum can be reused repeatedly and requires very little processing to make it available for reuse. Manufacturers simply melt down crushed aluminum stock and add it to freshly extracted aluminum without any degradation of quality in the finished product. According to the U.S. Environmental Protection Agency, recycling an aluminum can requires less than 5 percent of the energy that would be expended in creating a similar can out of fresh bauxite ore. The Aluminum Association estimates that the energy saved in recycling a single aluminum can could power a television for 3 hours. Aluminum

9 Ok modelli.. Now something we can take notes on..  Recycling aluminum requires only 5% of the energy it would be required to manufacture an aluminum can from the bauxite ore..  Energy enough to power a TV for 3 hours! (that is a lot of xbox time)  Recycling aluminum requires only 5% of the energy it would be required to manufacture an aluminum can from the bauxite ore..  Energy enough to power a TV for 3 hours! (that is a lot of xbox time)

10  recycled aluminum can comes back to the grocery store shelf as a new can in as little as 60 days  Aluminum cans are the most recycled item in the US  More aluminum is used to make cans than any other product  Because they are recycled at a high rates aluminum cans make up less than 1% of the waste in the US, that is awesome yo!  We use more than 80,000,000,000 aluminum cans every year…  recycled aluminum can comes back to the grocery store shelf as a new can in as little as 60 days  Aluminum cans are the most recycled item in the US  More aluminum is used to make cans than any other product  Because they are recycled at a high rates aluminum cans make up less than 1% of the waste in the US, that is awesome yo!  We use more than 80,000,000,000 aluminum cans every year…

11 plastic  Seven major types of plastic are found in consumer products, and recycling can extend the use of most of them. Recycling plastic requires only a tenth of the energy needed to create new plastic from raw materials.

12  Americans (that’s us) use 2,500,000 plastic bottles every hour! Most of them are thrown away… stop that!  Plastic bags and plastic garbage thrown in the ocean kill as many as 1,000,000 sea creatures every year..  Recycling plastic saves twice as much energy as burning it into an incinerator  Americans (that’s us again) throw away 25,000,000,000 styrofoam coffee cups every year  Americans (that’s us) use 2,500,000 plastic bottles every hour!

14 paper  Recycling paper not only saves energy but also saves trees, reducing the amount of carbon dioxide present in the atmosphere. The EPA estimates that producing a recycled paper product requires only 60 percent of the energy required to create one from fresh wood pulp, and the Energy Administration Information reports that recycling a ton of paper can save 17 trees. Recycling paper also requires about half the water normally used in processing paper from virgin wood.

16 glass  Glass recycling is less efficient than many other forms of recycling, due to the processing required to return glass to a usable, raw state. According to the EPA, recycling glass only saves about 30 percent of the energy cost of producing new glass, and the raw materials required are in abundant supply. Reusing glass bottles and jars, however, requires no energy whatsoever, so you can reduce energy costs by finding new uses for these containers instead of simply throwing them out. Once you throw glass out, 1 million years will pass before that glass breaks down at the landfill

17 +Each person creates about 4.7 pounds of waste every single day +In the US 33.4% of solid waste is either recycled or composted, 12.6% is burned in combustion facilities and 54% makes it's way into landfills +In 2007 99% of lead acid batteries were recycled, 54% of paper and paperboard were recycled, 64% of yard trimmings are recycled and nearly 35% of metals were recycled +The amount of recycling in 2007 saved the energy equivalent of 10.7 billion gallons of gasoline and prevented the release of carbon dioxide of approximately 35 million cars

20 The number of landfills in the US are decreasing while their size is increasing. In 1998 there were 8,000 landfills but only 1,754 in 2007 Each ton of mixed paper that is recycled can save the energy equivalent to 185 gallons of gasoline Approximately 8,660 curbside recycling programs exist in the United States There are about 3,510 community composting programs in the United States Disposal of waste to landfills has decreased from 89% in 1980 to 54% in 2007 Recycling 1 ton of aluminum cans conserves the equivalent of 1,665 gallons of gasoline In 2007 the United States recycled and composted 85 million tons of the 254 million tons of municipal solid waste created The number of landfills in the US are decreasing while their size is increasing.

21  Every month we throw out enough glass bottles and jars to fill out a giant skyscrapper  The energy saved from recycling 1 glass bottle can power a 100watt light bulb for 4 hours or a CFL for 20 hours  Causes 20% less air pollution and 50% less water pollution than making a new bottle from raw materials  A modern glass bottle will take over 4000 years to decompose and much longer if it is in a landfill  Mining and transporting materials to make glass produces 385 pounds of waste…if recycled glass is substituted for half of the raw materials and waste is reduced by 80%  Every month we throw out enough glass bottles and jars to fill out a giant skyscrapper  The energy saved from recycling 1 glass bottle can power a 100watt light bulb for 4 hours or a CFL for 20 hours  Causes 20% less air pollution and 50% less water pollution than making a new bottle from raw materials  A modern glass bottle will take over 4000 years to decompose and much longer if it is in a landfill  Mining and transporting materials to make glass produces 385 pounds of waste…if recycled glass is substituted for half of the raw materials and waste is reduced by 80%
