Can I compost leftover cooking grease and oil?

We do not accept fats, oils, and leftover grease in the composting program. These items can be recycled at the County’s Household Hazardous Waste (HHW) Acceptance Site located at the Brown Station Road Sanitary Landfill, 11611 White House Road, Upper Marlboro, MD 20774. The facility is open on Thursday, Friday, and Saturday only from 8 a.m. – 3:30 p.m.
