Montgomery County Resource Recovery Facility Processes 10 Millionth Ton of Waste Into Renewable Energy

DICKERSON, MD--(Marketwired - Dec 5, 2013) - The Montgomery County Resource Recovery Facility (RRF), operated by Covanta Montgomery, Inc., is celebrating the milestone of processing 10 million tons of post-recycled municipal solid waste into clean, renewable energy.

The energy-from-waste facility is owned by the Northeast Maryland Waste Disposal Authority and began commercial operation in August 1995 to sustainably dispose of Montgomery County's post-recycled waste. By recovering energy from 10 million tons of waste at the RRF instead of disposing waste in landfills, the County has:

  • Produced 5.7 billion kilowatt hours of electricity, enough to power Washington D.C. for six months
  • Offset 10 million tons of greenhouse gases, the equivalent to the avoided emissions from almost 2 million cars
  • Recycled 260 thousand tons of ferrous metal -- enough to replace 1,136 miles of rail from Washington, D.C. to New Orleans
  • Saved landfill space equal to waste piled 1.4 miles high on a football field

The RRF is a key component to the County's integrated solid waste management system, which includes robust recycling programs. The County consistently achieves a recycling rate exceeding 50 percent -- far above the national average. Waste that remains after recycling is sent to the RRF for energy recovery where up to 52 megawatts of clean energy is generated -- enough to power approximately 38,000 homes continuously.

"Montgomery County should be applauded for their foresight to build the RRF instead of continuing the unsustainable practice of landfilling waste," said Covanta Montgomery Business Manager Mark Freedman. "Instead, we have safely handled waste as part of an integrated system which supports recycling, generated clean renewable energy for County households and reduced greenhouse gases."

Montgomery County utilizes a unique rail system to transfer waste and avoid truck traffic associated with the facility. All waste is first delivered to the Shady Grove Transfer Station in Derwood, compacted into intermodal steel waste containers and then loaded onto railcars. The waste is then transferred 20 miles via rail to the RRF in Dickerson. There the containers are off-loaded and trucked from the on-site rail yard to the facility's enclosed refuse building. Residue that remains from the process is loaded into sealed containers and shipped by rail. By using rail to deliver waste to the facility, the County has avoided 9 billion road-miles of truck traffic and the associated emissions from approximately 225,000,000 diesel truck trips since its operation began in 1995.

In 2010, 2005 and 1998 the facility received the "Gold Waste to Energy Excellence Award" from the Solid Waste Association of North America. This award considered all aspects of waste to energy operations and represents the highest level of excellence among the nation's energy-from-waste facilities. Other awards received include, the American Society of Mechanical Engineering Excellence in WTE Operations Award, the American Association of Environmental Engineers Grand Prize for Operations/Management and the American Society of Civil Engineering Outstanding Civil Engineering Project Award. 

As operators of the facility, Covanta Montgomery is an active member of the community and supports a number of local organizations such as Western Upper Montgomery County Help, 4H, the Upper Montgomery County Volunteer Fire Department and Local Relay for Life. 

Recovering energy from waste after efforts to reduce, reuse and recycle have been employed is a critical component of managing residual waste. For every ton of municipal solid waste processed at energy-from-waste facilities like Montgomery County RRF, greenhouse gas emissions are reduced by the equivalent of approximately one ton of carbon dioxide emissions. This is possible due to the avoidance of methane from landfills, the offset of greenhouse gases from fossil fuel electrical production and the recovery of metals for recycling.
