In most parts of the world, municipal solid waste is largely landfilled or incinerated. However, increased attention has been given to alternative waste management options such as source separation into organic and inorganic fractions, where the organic fraction is  treated through composting,  or anaerobic digestion with accompanying biogas production, and a refuse derived fuel is extracted from the inorganic fraction. Other treatment technologies include pyrolysis and gasification.

ECWM operates two Open Windrow Composting facilities that process between 750,000 to 1,000,000 tons of organic matter annually. Composting helps divert organic matter from landfills, which minimizes biogas emissions.
