Municipal Solid Waste
a.k.a. Your Trash & Garbage
Information and images courtesy of US EPA unless otherwise noted.
Just the Facts
1. In 2012, Americans generated about 251 million tons of trash and recycled and composted almost 87 million tons.
2. On average, we recycled and composted 1.51 pounds of our individual waste generation of 4.38 pounds per person per day.
Food waste: 14.5%
Yard Trimmings: 13.5%
Wood: 6.3%
Rubber, Leather, textiles: 8.7%
Plastics: 12.7%
Metals: 8.9%
Glass: 4.6%
Paper/Paperboard: 27.4%
Other: 3.4%
Landfills
2. Some materials may be banned from disposal in municipal solid waste landfills including common household items such as paints, cleaners/chemicals, motor oil, batteries, and pesticides. These products, if mishandled, can be dangerous to your health and the environment. Many municipal landfills have a household hazardous waste drop-off station for these materials.
Combustion
1. In 2012, over 29 million tons of materials, or 11.7 percent, were burned for energy recovery (to create electricity).
2. Combustion for energy recovery has decreased from about 34 million tons in 2000 to 29 million tons in 2012 because new plants are not being built.
3. Why not burn our solid waste? It doesn’t solve the problem – the ashes still go to the landfill.
Composting
2. All composting requires three basic ingredients:
Browns - This includes materials such as dead leaves, branches, and twigs.
Greens - This includes materials such as grass clippings, vegetable waste, fruit scraps, and coffee grounds.
Water - Having the right amount of water, greens, and browns is important for compost development.
3. A compost pile should have an equal amount of browns to greens.
4. Benefits of Composting
a. Enriches soil, helping retain moisture and suppress plant diseases and pests.
b. Reduces the need for chemical fertilizers.
c. Encourages the production of beneficial bacteria and fungi that break down organic matter to create humus, a rich nutrient-filled material.
d. Reduces methane
emissions from landfills
and lowers your carbon
footprint.
Reduce…
1. The most effective way to reduce waste is to not create it in the first place. Making a new product requires a lot of materials and energy: raw materials must be extracted from the earth, and the product must be fabricated and then transported to wherever it will be sold. As a result, reduction and reuse are the most effective ways you can save natural resources, protect the environment, and save money.

Recycle!
1. Why recycle?
Recycling
1. Since 1990, the total amount of MSW going to landfills dropped by over 11 million tons, from 145.3 million to 135.0 million tons in 2012.
2. Recycling and composting prevented 86.6 million tons of material away from being disposed in 2012, up from 15 million tons in 1980. This prevented the release of approximately 168 million metric tons of carbon dioxide equivalent into the air in 2012—equivalent to taking over 33 million cars off the road for a year.
There were more than 1.2 billion cars on the road in 2012.
Electronics
1. Electronic products are made from valuable resources and materials, including metals, plastics, and glass, all of which require energy to mine and manufacture. Donating or recycling consumer electronics conserves our natural resources and avoids air and water pollution, as well as greenhouse gas emissions that are caused by manufacturing with new materials.
2. For example, for every million cell phones we recycle, 35 thousand pounds of copper, 772 pounds of silver, 75 pounds of gold, and 33 pounds of palladium can be recovered.
Why don’t we recycle more stuff?
1. Plastic bags have virtually taken over the grocery market since they were first put at check-out stands in 1977. Ninety percent of all grocery bags are now plastic – that is as many as one trillion plastic bags.
2. Every year, Americans use approximately more than a billion plastic bags, creating tons of landfill waste. It can take 1,000 years for a plastic bag to decompose.
3. Less than 1 percent of plastic bags are recycled each year. Recycling one ton of plastic bags costs $4,000. But the recycled product can only be sold for $32.
4. It’s all about supply and demand. If more people want products made from recycled materials, recycling will become more profitable.
