Recycle at the Alpha Ridge Convenience Center

Residents can place rigid plastics into a large roll-off marked “Rigid Plastic.” If there is any question about whether a plastic object is recyclable or not, please check with the guardhouse or call 410-313-6444. Please be advised, rigid plastics should not be placed into the compactors that collect single-stream recycling material.

Alpha Ridge Landfill is located at 2350 Marriottsville Road, Marriottsville, and is open Monday through Saturday, 8 a.m. to 4 p.m.
