American
Ref-Fuel’s flagship facility, in Hempstead, New York,
opened for business in 1989. The Hempstead facility, Long
Island’s largest waste-to-energy plant, provides
environmentally safe municipal solid waste disposal for
the nation’s most populous township. It marks the
first United States installation of a globally successful
mass burn technology, Deutsche Babcock Anlagen.
The Hempstead
facility accepts delivery of waste six days a week and
processes on a 24-hours-a-day, seven days a week basis.
Steam created in the combustion process drives a 72-megawatt
turbine generator producing electricity for in-plant use
and for sale to the local utility. Three dry scrubber systems
control acid gases, as do fabric filters, minimizing the
release of particulates before exiting the exhaust stack.
The Hempstead
facility is the cornerstone of the town’s integrated
waste service plan that includes an extensive curbside
collection system for recyclable materials and a long-term
agreement with neighboring Brookhaven for disposal of ash
residue.
OSHA designated
the Hempstead plant a Star facility in 1994. American Ref-Fuel
Company of Hempstead set the OSHA Star standard for all
other waste-to-energy facilities in the nation, as it received
the very first Star in the industry. |

Hempstead was accepted into the
EPA's Performance Track Program in 2002. This is a voluntary
partnership program that recognizes and encourages top
environmental performers. The program is a counterpart
to OSHA's VPP recognition of superior health and safety
- a program in which the Hempstead plant had been the first
waste-to-energy facility in the nation to attain the VPP
Star designation. |
