Organics Diversion and Composting

Waste Managed in U.S. in 2013

Compostable materials such as food scraps and yard trimmings make up nearly 30% of all municipal solid waste generated in the U.S.  Instead of disposing of this material in landfills and incinerators, composting uses organic material to create a valuable product with environmental and economic benefits, including greenhouse gas emissions reductions and green jobs.

Recycling of some organic materials, such as yard trimmings and manure, is widespread in Maryland.  One area of growing interest is food scraps diversion.  Though only an estimated 9.6% of food scraps was recycled in Maryland in 2014, much of the remaining material could be prevented, used to feed humans or animals, or composted.
