Montgomery County Yard Trim Composting Facility
We began composting yard trim at the Montgomery County Yard Trim Composting Facility in 1983. The program originated with the composting of leaves collected by the Department of Public Works and Transportation's curbside leaf vacuuming program.
Between 1989 and 1994, the program gradually expanded to include grass. Today, material is collected from all single family residences in the County. We also receive it from commercial and multi-family facilities. The finished product is marketed as Leafgro.
The 118-acre site includes
- a 49-acre asphalt pad
- three stormwater management ponds
- an 80,000 square foot pavilion for drying and screening of finished compost
- an office/scalehouse
- a maintenance building
- a storage building
- a pump house for the on-site well.
The facility is owned by Montgomery County, and is operated by the Maryland Environmental Service (MES), with nine employees on site.
The site is located adjacent to the Montgomery County Resource Recovery Facility. It has an estimated annual processing capacity of 77,000 tons of material.
Our Composting Facility is the second one in the United States to have registered its Environmental Management System in conformance to ISO 14001:2004. Read our article about the certification process in the January 2014 issue of Biocycle magazine.
The facility received the Solid Waste Association of North America's 2005 Silver Excellence Award in the Waste Reduction, Recycling and Composting Division. This awards program recognizes technically and economically-sound municipal solid waste management programs that are protective of public health and the environment.
