This is because the law requires that modern landfills be designed to keep sunlight, air and moisture out of the landfill. This helps prevent pollutants from the garbage from entering the air and drinking water, but also slows decomposition. Even materials like paper and food may take decades to decompose in a landfill. Most of these products have always degraded in wastewater systems, causing no harm to the environment. Some people compost yard trimmings and food scraps in their backyards.
Many communities collect leaves, grass, and other yard trimmings for composting.
If you want to compost a product in a community facility, check to be sure that your community facility accepts the material for composting. All Ozone Is Not Alike. But all ozone is not alike.

But when ozone develops at ground level, it forms smog, which can cause some people to have serious breathing problems.
