Reducing Landfill Waste

Located in Rahway, New Jersey, the Union County Resource Recovery Facility is an award-winning Waste-to-Energy Facility. The Facility is owned by Union County Utilities Authority and serves Union County with sustainable waste management.

In addition to keeping waste out of landfills, we’re 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 540,000 tons of waste that would otherwise have ended up in landfills.

co2-down-icon

Less waste in landfills reduce greenhouse gas emissions by 507,600 tons of CO2. That’s like taking 98,000 passenger vehicles off the road for one year.

power-a-house-icon

We use waste to produce 42 megawatts of electricity 24/7 - enough to power 26,000 homes for a year.

recycle-icon

We also recover 18,100 tons of metal for recycling annually - enough to build 14,000 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 are well below federal and state standards.

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

  1. Permit Limits are derived from USEPA standards for Large Municipal Waste Combustors (40 CFR 60, Subparts A, Cb and Eb).
  2. CO values are the maximum 4-hour block average for that day.
  3. SO2 and NOx values are the daily (24-hour) block averages for that day.
  4. Opacity values are the maximum 6-minute average for that day.
  5. 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 %, Removal Efficiency as %.
  6. SO2 compliance is based on concentration (ppm) or removal efficiency (% reduction between inlet and outlet emissions).
  7. The dash symbol (-) indicates that a unit is off-line, has insufficient data for a compliance period or is in an exempted period.

*Results are provided for informational purposes only. Data is posted 24 hours after completion of each day to allow for quality assurance/quality control (QA/QC) review.

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.
