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

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.

Silver Composting Award

On June 17, 2014, the Solid Waste Association of North America (SWANA) named Montgomery County, Maryland, as the winner of the SWANA Silver Excellence Award in the Composting category.  SWANA recognized the County’s Yard Trim Composting Facility as state-of-the-art and cost effective.  In addition, the County demonstrated how to develop a formal Environmental Management System (EMS) meeting the rigorous international ISO 14001:2004 standard.  The facility’s EMS is only the second such facility in the nation to be independently certified as in conformance with the ISO standard.  Read our article about the certification process in the January 2014 issue of Biocycle magazine.

The facility also received a 2014 National Association of Counties Achievement Award for the EMS and its development.
