DSWA consistently strives to design innovative internal recycling solutions to help create a safe environment for our future. Many items accepted at our landfills or transfer stations are recycled as well.

  • White Goods

    Appliances such as air conditioners, refrigerators, and freezers called “white goods,” that contain chlorofluorocarbons (CFCs) are first drained of CFCs for recycling. Then, they are sold with non-CFC white goods such as washers, dryers, and water heaters for scrap metal recycling.

  • Yard Waste

  • Tires

    Tires are kept separate from other solid waste and transferred to various mid-Atlantic regional facilities for energy recovery, which uses tires as alternative fuels.

  • Landfill Gas

    By collecting landfill gas at Cherry Island and pumping it to the Delmarva Power plant in Edgemoor, where it is burned with conventional fossil fuels, we help generate more electricity while using fewer natural resources. DSWA also collects landfill gas at its Sandtown and Jones Crossroads Landfill.  Ameresco developed, owns, and operates the two-landfill gas-to-energy power plants at DSWA’s Sandtown and Jones Crossroads Landfills. Tons of naturally occurring methane, is now being captured and converted into “green” electricity.  Before the landfill gas project, the methane gas was safely extracted at the landfill sites through wells and pipes buried in the landfills and combusted in a flare. The gas is now diverted from the flare to the landfill gas plants equipped with specialized GE/Jenbacher engines designed to burn non-pipeline gases such as landfill gas. The seven engines can produce a combined 7.4 megawatts (MWs) of electricity – enough to meet the annual power needs of over 4,500 homes. Constellation NewEnergy, North America’s largest competitive power supplier, has signed a ten-year agreement to purchase the power from the two plants. Using methane from landfills for power production will help reduce global warming.

  • Construction & Demolition (C&D)
  • Leachate

    When rain falls on the landfill, it mixes with the trash as it seeps through soil and garbage, picking up toxins along the way. This liquid is called leachate. DSWA circulates leachate through our landfills to accelerate waste decomposition before collecting it through a series of collection pipes which pump the leachate to holding tanks. The leachate is then hauled away by truck to be purified at a special wastewater treatment facility and released into the environment.
