Covanta’s specially designed “Energy-from-Waste” (EfW) facilities produce electricity and/or steam for export through the combustion of post-recycled, non-hazardous municipal solid waste (“MSW”) that has been diverted from landfill. EfW facilities are defined as renewable by 30 states, the District of Columbia, Puerto Rico, U.S. federal law, Europe and China and are recognized as preferable to landfilling in the solid waste management hierarchy.

Huntsville EfW facility

EfW facilities are a widely recognized means for reducing greenhouse gases—particularly methane—by eliminating emissions that would have otherwise occurred in landfill. Compared to landfills equipped with gas-to-energy recovery systems, EfW facilities are nine to 14 times as effective in capturing the energy that remains in MSW after recycling.

EfW facilities are also resilient sources of baseload energy, meaning they generate their electricity consistently. As a result, they serve as a valuable complement to intermittent renewable resources, such as wind and solar. EfW facilities are also often built near demand, where power is delivered for distribution to the grid. This proximity reduces the energy losses associated with long-distance transmission of electricity and provides unique opportunities for integration of EfW facilities in local community microgrids.

Several of our facilities export steam to local communities, businesses, and even an army base. The facility we operate in Huntsville, Alabama, provides up to 180,000 pounds of steam per hour to the Redstone Arsenal for heating and cooling needs. We also operate four combined heat and power (CHP) plants that generate both steam and electricity, resulting in greater overall efficiencies in capturing the heat energy available in the waste resource. Our Niagara Falls facility’s steam supplies a local industrial park, including a 100% recycled paper mill as a perfect example of how EfW contributes to a Circular Economy. Our Dublin, Ireland, facility will be joining the list of CHP plants shortly—Dublin’s District Heating Scheme, scheduled to begin construction in 2020, will be linked to our EfW facility. The plant will have the potential to provide enough steam heat for up to 50,000 more homes.

 

Development Overview – U.K. 

The United Kingdom is committed to more sustainable waste management through the diversion of waste from landfills to energy recovery and recycling. Covanta is proud to be part of this transformation through the construction of new EfW capacity with our partner Green Investment Group.
