1. Solid and liquid waste is delivered to an EfW facility and stored for processing. 2. The waste is transferred to a combustion chamber where self-sustaining combustion is maintained at extremely high temperatures. The facility maintains the building around the tipping and bunker area under negative pressure and uses this air in the combustion process to control odor. 3. The heat from the combustion process boils water. Continue reading
Energy can be recovered via energy-from-waste (EfW) processes from residual waste left over after efforts to reduce, reuse, and recycle have been exhausted. The process is simple: Solid and liquid waste is transferred to a combustion chamber; the heat from the process boils water, which makes steam which drives a turbine that generates electricity.

- Energy from waste uses solid waste as a fuel to generate clean, renewable energy.
- EfW facilities export to the grid an average of 550 kWh of electricity for every ton of waste processed.
- Each year EfW facilities in North America prevent more than 25 million tons of greenhouse gases and CO2 equivalents from being released into the atmosphere.
As manufacturers continually look to implement practical sustainability strategies and increase environmental stewardship, addressing the waste steam has become a priority. As a result, zero-landfill goals Continue reading
Editor’s Note: Covanta 4Recovery expert Derek W. Veenhof, senior vice president of Covanta 4Recovery L.P., a subsidiary of Covanta Energy Corp., fields questions about the energy-from-waste process, also called waste-to-energy, and its role in sustainable waste management, as well as dispels some myths about its effects.
