Covanta Waste-to-Energy Facility Completes Environmental Upgrade – Official Arlington County Virginia Government Website

Posted on August 08, 2022

Covanta, a leader in sustainable materials management and a leading provider of environmental solutions for businesses and communities, announced that the Covanta Alexandria Waste-to-Energy facility recently completed planned upgrades to its technology state-of-the-art pollution control. The aim is to further reduce nitrogen oxide (NOx) emissions, thereby helping to protect the environment.

The Alexandria-based waste-to-energy facility serves 400,000 residents and businesses in the City of Alexandria and Arlington County. It provides reliable and sustainable waste management by burning non-hazardous household waste at high temperatures, which then generates steam for renewable electricity generation. In this way, Covanta treats and converts into energy more than 350,000 tons of waste that would otherwise end up in landfills.

“Installing this new NOx technology will further reduce emissions and improve air quality,” said Alexandria Mayor Justin Wilson. “This is a significant effort to help the City of Alexandria achieve the goals of its 2040 Environmental Action Plan.”

With the installation of Covanta’s exclusive Low NOx (LN) technology now complete, nitrogen oxide emissions have been reduced by almost 50%. The effort was part of a multi-year project at the Covanta Alexandria-Arlington facility. By reducing waste going to landfill, Covanta Alexandria reduced greenhouse gas emissions by 331,000 tonnes of carbon dioxide. This is equivalent to taking 65,000 passenger vehicles off the road for a year.

“Covanta prides itself on managing our services and facilities in a way that puts our communities, our businesses and our planet first,” said Don Cammarata, Covanta region asset manager. “Today marks an important milestone in our work with the community to reduce our environmental impact and improve air quality.”

Low NOx technology is unique in the industry and demonstrates Covanta’s commitment to investing in research and development to deliver superior environmental performance.

“Our continued partnership with Covanta is important to Arlington and we applaud their efforts to reduce NOx emissions to reduce our impact on the environment,” said Katie Cristol, Arlington County Board Chair. “Converting waste that would typically end up in landfills into energy makes our community more sustainable.”

The facility also recovers 11,200 tonnes of metal per year and produces enough energy to power 15,000 homes 24/7 for a year.
