Reducing Landfill Waste

Located in Westbury, New York, Covanta Hempstead is an award-winning Waste-to-Energy Facility that serves the Town of Hempstead with reliable and 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.

We are an active community partner and support a range of initiatives such as Wreaths Across America and encouraging STEM education for local students. Recently, the facility launched an American Flag retirement program in collaboration with local veteran groups. The program retires old and worn flags in accordance with the U.S. flag code.

Fast Stats: Annual Performance

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


Less waste in landfills reduce greenhouse gas emissions by 1,000,000 tons of CO2. That’s like taking 200,000 passenger vehicles off the road for one year.


We use waste to produce 80 megawatts of electricity 24/7 - enough to power 55,400 homes for a year.


We also recover 35,900 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 are well below federal and state standards.

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.
