Landfill Operations Horry County Solid Waste Authority

Compost & Mulch

All yard waste is banned from South Carolina municipal solid waste landfills, according to state law. The SWA naturally recycles yard waste into mulch and compost, which is available for sale to the public. 

Horry County Solid Waste Authority offers compost, mulch and glass aggregate for sale to residents and businesses for landscaping and gardening purposes. They are sold at the county landfill located at 1886 Highway 90 in Conway and you must come and collect the material. The Solid Waste Authority does not deliver. The facility is open 8 a.m. to 4 p.m. Monday through Saturday. 

Compost - made from ground yard trimmings (e.g., leaves, branches, grass) and costs $22 per ton. Enhanced Compost is also available for $30 per ton which has added nutrients from food scraps. Please call (843) 347-1651 to see if compost is available. Quantities are limited and the supply runs out quickly.

Natural Mulch - made from ground land-clearing debris (e.g., large branches, stumps, trunks) - also is available for $22 per ton. This mulch is an all-natural product. No chemicals or dyes are added.  Colored mulch - red, brown and black - is also available for $70 per ton. Please call (843) 347-1651 to see if mulch is available.                 

Glass Aggregate - made from ground glass bottles and jars - can be used in art projects, yard projects, driveways, flower beds, fish ponds and other landscaping projects. The aggregate is available in two sizes and costs $5 per ton. One size is a "sand" and the other size is similar to small pebbles .

Green Power

Green Power is a renewable energy partnership between the SWA and Santee Cooper. Electricity is generated from the methane gas from the SWA landfills and used throughout homes in Horry County. Santee Cooper owns and operates the generating equipment, which runs 24 hours a day, seven days a week. The Horry County Solid Waste Authority owns and operates the landfill, methane gas collection system and sells the fuel to Santee Cooper. Horry Electric Cooperative and Central Electric Power Cooperative supply the lines for the Green Power to travel.

The Green Power Program started in September 2001 through a partnership between the Horry County Solid Waste Authority and Santee Cooper. Since its inception, the Green Power Program has expanded to include residential and commercial customers across Horry County. In 2002, Myrtle Beach became South Carolina's first Green Power City. Green power programs started in 1993 and have grown to 80 programs in 28 states.
