The three main problems with landfill are toxins, leachate and greenhouse gases. Organic waste produces bacteria which break the rubbish down. The decaying rubbish produces weak acidic chemicals which combine with liquids in the waste to form leachate and landfill gas.

What happens to plastic in a landfill?
In 2014, Americans discarded about 33.6 million tons of plastic, but only 9.5 percent of it was recycled and 15 percent was combusted to create electricity or heat. Most of the rest ends up in landfills where it may take up to 500 years to decompose, and potentially leak pollutants into the soil and water.
