City of Columbia Landfill

The City of Columbia Bioreactor Landfill operates using environmentally-sound engineering practices for disposal of solid waste while complying with state and federal regulations. The current disposal cell (Cell 5) is the second cell permitted to operate as a bioreactor, where liquids are added to the waste to accelerate decomposition, waste stabilization, and gas production. Methane gas generated from the landfill is being converted to electricity at the on-site Bioenergy Plant operated by the Water & Light Department since June 2008. A small vehicle drop-off is available for customers that want to avoid driving on the landfill. The small vehicle drop-off containers are located immediately after passing the scale house. This drop-off location is intended to improved customer convenience and operational safety since driving onto the landfill could be hazardous for small vehicles.
