Organics Diversion and Composting
Composting Facility Regulations Adopted (COMAR 26.04.11)
On June 12, 2015, a Notice of Final Action was published adopting new composting facility regulations, which are effective July 1, 2015. The Final Action adopted the regulations as proposed in December 2014, with several minor nonsubstantive changes. The changes are listed in the Notice of Final Action.
Important Deadline for Existing Composting Facilities
Existing composting facilities are those that began operations on or before July 1, 2015. An existing composting facility that is subject to the Composting Facility (CF) Permit is required to submit to MDE an Existing Facility Notification (EFN) Form by September 1, 2015.
An existing composting facility that submits to MDE a timely EFN Form will have until January 1, 2017 to come into compliance with the composting facility regulations and obtain the CF Permit, if the facility:
- Accepts only feedstocks that were accepted as of July 1, 2015 that were described in the EFN Form;
- Accepts materials in quantities not exceeding the annual quantity reported in the EFN Form; and
- Does not engage in composting in a manner likely to cause any prohibited acts under COMAR 26.04.11.04B.
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 8.5% of food scraps was recycled in 2012, much of the remaining material could be prevented, used to feed humans or animals, or composted.
The following are collections of organics diversion resources targeted to various audiences. These resources can help you start an organics diversion program at work, school, or home, or simply learn more about compost and its use.
