Horry County SWA - Solid Waste Operations

Solid Waste Operations

The HCSWA site includes a Class 2 Landfill, a Class 3 Landfill, a Class 2 Processing Facility, and a composting facility.

A Class 2 Landfill can accept construction and demolition debris landfill such as asphalt, concrete, lumber, cardboard, shingles, glass, and land-clearing debris. Class 2 Landfills are not required to have a liner system. Because HCSWA is proposing to construct a Class 3 Landfill atop its Class 2 Landfill, the Class 2 Landfill will eventually contain a liner system as part of its final cover. 

A Class 3 Landfill can accept municipal solid waste, construction and demolition debris, non-hazardous industrial waste, sewage sludge, and other non-hazardous waste – although not all are accepted by HCSWA. A Class 3 Landfill cannot accept hazardous waste, infectious waste, or land-clearing debris for disposal. Class 3 Landfills are required to have a liner system. 

A Class 2 Processing Facility can accept the same waste as a Class 2 Landfill; however, the waste is sorted to determine what can be recycled and what must go to the landfill. The operation of this facility allows Horry County to divert roughly 12,000 tons of waste from its landfill each year – not including the carpet and concrete that is also diverted annually. 

A composting facility can accept land-clearing debris and other yard trimmings that are turned into compost. HCSWA also adds food waste into its composting piles.
