Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.
Is a flammable gas produced by landfills?

How far does Landfill smell travel?
How far can landfill gas travel? It is difficult to predict the distance that landfill gas will travel because so many factors affect its ability to migrate underground; however, travel distances greater than 1,500 feet have been observed.
