The Delaware Valley Resource Recovery facility, operating as Covanta Delaware Valley, L.P., is located in Chester, Pennsylvania and has been in operation since 1992. Covanta began operating the facility in 2005. In 2012, Covanta became the owner and operator of the facility when the company purchased the facility from GE Energy Financial Services. The plant processes up to 3,510 tons of municipal and commercial solid waste each day. At maximum output, the plant generates approximately 80 megawatts of electricity, 90 percent of which is sold to the local utility. The plant not only meets the municipal solid waste disposal and energy production needs of Delaware County, but also provides capacity for up to 500,000 tons of additional waste each year from surrounding counties. The facility also recovers ferrous (steel) and non-ferrous (aluminum) metals.
