Here is some plastic and landfill information.

Making new plastic requires significant amounts of fossil fuels. Studies suggest that between 7% and 8% of the world’s fossil fuels are used in producing new plastics. This doesn’t sound like a great amount, but it accounts for millions of tons of fuels per year. Recycling could preserve these fuels—even reuse them in other markets.

Plastic is easy to recycle - although few people do it. All plastic can be recycled. But it’s not being recycled as much as it should be. Some studies show that only 10% of plastic bottles created are recycled, leaving that extra 90% to take up space in landfills and killing ocean life.

Plastic bottles take up space in landfills. Our country’s landfills are closing at a rate of around two per day. The landfill-space crisis is especially problematic in cities, where inner-city trash dumps are often filled to capacity, and surrounding communities are unwilling to allow new landfills to come to their neighborhoods. Many coastal cities use the ocean as a dumping ground, resulting in depleted fish stock, polluted beaches, and other health issues for the inhabitants. Plastic bottles make up approximately 11% of the contents of landfills.

Incinerating plastic contributes to greenhouse gases. To save space at landfills, plastics are often burned in incinerators. When this is done, chemicals, petroleum, and fossil fuels used in the manufacturing process are released into the atmosphere, adding to greenhouse gas emissions.

Plastic in the oceans is responsible for the deaths of millions of sea animals. Plastic bottles floating on the surface of the oceans can look like food to larger sea life—often with fatal consequences. In addition, fish, sea birds, and other ocean creatures often get caught in plastic rings that strangle them or constrict their throats so that they cannot swallow.

Plastic takes a long time to degrade. Nobody is quite sure how long it takes for plastic to biodegrade—it hasn’t been around long enough, and the first plastics made are still around today. Scientists believe, however, that plastics will take hundreds of years to degrade fully—if not longer. Plastics as we know them have only been around a hundred years, and they are already a problem. Imagine five hundred years’ worth of plastics in our landfills.

Plastics contain harmful chemicals. These include cadmium, lead, PVC, and other pollutants in the form of artificial coloring, plasticizers, and stabilizers. Some of these have been discovered to be harmful and are not in currently-manufactured plastics, but the older, more toxic plastics are still filling up our landfills and floating around in our oceans, releasing pollutants into the environment. These can seep into groundwater from landfill runoff and cause health risks for both wildlife and humans.
