What it takes

It’s one of nine Harford County recycling centers that take used motor oil. The Harford Waste Disposal Center takes tires, appliances, mattresses, some paint, electronics, construction debris, and some batteries. The Harford Mulch & Compost Facility and the Tollgate Residential Yard Trim Drop-Off take brush.

Each item has its own rules. Check before you go.

Harford County rules

  • The Harford Waste Disposal Center is for Harford County residents only: every driver shows a Maryland driver’s license with a current Harford County address. Businesses must be licensed haulers and go to the Eastern Sanitary Landfill in White Marsh.
  • Yard trim isn’t accepted in plastic bags; bring it loose, bundled, in paper bags or boxes, or empty it from your own containers. Show a Maryland driver’s license.
