This link describes how composting can help lower greenhouse gas emissions.
Tackling the problem of food waste is gaining attention to avoid garbage, conserve resources, create jobs, alleviate hunger, and reduce greenhouse gas emissions. A new report from the Institute for Local Self-Reliance (ILSR) details how home composting is among the best opportunities to reduce food waste, especially in the near term and in areas lacking curbside collection or facilities to compost.
The 90-page report found that for every 10,000 households composting at home, between 1,400 and 5,000 tons per year could be diverted from curbside collection, with potential savings in avoided disposal costs alone ranging from $72,000 to $250,000.
