A Key to Rapid Methane Reduction: Keeping Organic Waste from Landfills

Waste is the third largest source of methane emissions, a greenhouse gas over 80 times as potent as CO2. Most waste sector methane emissions come from landfilling organic waste. This paper discusses how diverting organic waste from landfill is one of the fastest and most affordable ways to lower methane emissions.

With organics making up more than 50% of solid waste in Asia, managing this waste stream will have a huge impact on waste management and the reduction of methane emissions. 

With superb illustrations and easy-to-follow instructions, “Back to Earth” encourages people to explore every facet of composting: whether in a sprawling backyard or in a limited space such as a high-rise apartment, composting can be customized to suit any situation. 

The most important message, however, is that composting is a simple and yet effective step anyone can take to help alleviate the burden on our landfills, replenish soil nutrients, and reduce carbon and methane emissions. 


Zero Waste Europe welcomes the initiative of the European Commission to start the process to set-up binding food waste reduction targets across the EU. Food waste is a multifold problem that not only causes environmental and climate damage but is also morally unacceptable.

Therefore, it is essential to properly address this issue by adopting efficient and ambitious targets for the coming years.
