More than 1,250 people visit this 30-acre facility each week to dispose of Yard Waste, Food Waste and other organic materials, which are composted onsite and produced into thousands of tons of compost, topsoil and mulch each year for resale. The facility also features a small Convenience Center for the disposal of smaller quantities of household trash, recycling, bulky waste, and construction debris.

Historically, more than 30% of the waste that has entered the County Landfill was comprised of organic materials that could have been composted. However, since the grand opening of the newest Compost Facility, the County Compost Program has diverted 14% of organic waste away from the Landfill and repurposed it into Mulch and Topsoil for the community to use.
Because the Convenience Center is only equipped to handle small quantities of household trash, recycling, bulky waste, and construction debris, this service is only available to residents (for free) and residents of the town municipalities of Dumfries, Occoquan, Haymarket, or Quantico may utilize the facility for a fee. (Some exclusions may apply.)
