[RenewableEnergyAccess.com] Covanta Energy will construct, operate and maintain an estimated $106 million expansion to Florida’s Hillsborough County Solid Waste Energy Recovery Facility. Completion is expected within 28 months. Currently, the Facility’s three boiler units annually process more than 372,000 tons of solid waste, converted first to steam and then to electricity, which is sold to Tampa Electric Company. With the expansion, a fourth boiler unit will be added to increase annual processing capability by approximately 190,000 tons of solid waste per year. Additionally, at no cost to the county, Covanta will design, build and operate a new non-ferrous metal recovery system and will market non-ferrous metals recycled from the combustion residue.
