Reducing Landfill Waste

Located in Lorton, Virginia, the I-95 Energy/Resource Recovery Facility is an award-winning Waste-to-Energy Facility that serves the more than 900,000 in the Washington, D.C. suburbs of Fairfax County, Virginia with reliable and sustainable waste management.

In addition to keeping waste out of landfills, we are committed to ensuring safe operations and minimizing environmental impacts. We have been consistently recognized for exceptional operations, including OSHA’s stringent Voluntary Protection Program Star certification.

Fast Stats: Annual Performance

Every year, our facility processes more than 1,120,000 tons of waste that would otherwise have ended up in landfills.


Less waste in landfills reduce greenhouse gas emissions by 1,047,000 tons of CO2. That’s like taking 235,000 passenger vehicles off the road for one year.


We use waste to produce 93 megawatts of electricity 24/7 - enough to power 67,000 homes for a year.


We also recover 37,300 tons of metal for recycling annually - enough to build 27,000 cars.

Superior Environmental Performance

We care about our communities and operate well below emissions limits. Over 99.9 percent of what comes out of our plant’s stack is what you’d typically find in air - water vapor, nitrogen, oxygen, and carbon dioxide. The remaining constituents (as seen below) are well below federal and state standards.

The following data is presented in units required by the facility's permit as averaged emissions.

  1. CO values are the maximum 4-hr block average for the day.
  2. SO2 and NOx values are the daily (24-hr) block averages for that day.
  3. Opacity values are the maximum 6-minute average for that day.
  4. All emission values reported in units consistent with the permit. CO, SO2 and NOx reported as parts per million, dry gas basis at 7% O2 (ppmdv7), Opacity as %.
  5. SO2 compliance is based on concentration (ppm) or removal efficiency (% reduction between inlet and outlet emissions).
  6. The dash symbol (-) indicates that a unit is off-line, has insufficient data for a compliance period or is in an exempted startup/shutdown period.

* Results are provided for informational purposes only and are subject to adjustment based on allowable quality assurance/quality control (QA/QC) review. For updated information regarding Covanta’s compliance with its permits issued by the Virginia Department of Environmental Quality (VADEQ), final administrative (non-compliance) orders can be found on the VADEQ website. (Please note – if Covanta Fairfax is not listed, there are no VADEQ compliance orders to report).

Process in Action

Waste-to-Energy: How Does It Work?

Waste-to-Energy takes non-hazardous waste - otherwise destined for landfill - and combusts it to generate steam for electricity generation. Ash is processed to recover metal for recycling while all gases are collected, filtered and cleaned before being released safely into the atmosphere.
