Aslan Environmental Services, Inc., (AES) was founded in 2003 and is a technology company providing innovative independent engineering solutions to specific commercial, industrial and municipal problems.

Headquartered in Fishkill, N.Y., AES and has recently received the New York State 2008 Environmental Excellence Award for its successful adaptation of a large scale sewage sludge drying and pelletizing technology for small municipalities. Previously, the technology was available only for very large scale applications.

The NY State Department of Environmental Conservation described the process as an “innovative system for managing wastewater treatment plant solids and residuals in an economical and environmentally sound manner.”

Aslan Environmental was presented the award for its successful design, installation and operation of a plant in Kingston, N.Y., the first of its size in the world. The Kingston unit has been operating 24/7 since April 2007, with only five days of down time. To date, Kingston taxpayers have saved approx $100,000, and eliminated more than 4200 tons of sludge in landfills as a result of implementing this system.

AES is the only company in North America licensed to handle this design.

“This is a mature product based on proven technology that requires no up front capital expenditures, is effortless on the part of the municipality to implement, saves money and is completely green,” according to Mayor James Sottile of Kingston. It turns municipal sludge into pellets, and provides a clean, cost-effective and environmentally sound alternative to dumping sludge into landfills. The pellets can be sold as fertilizer thereby providing an additional source of revenue, or burned as fuel, providing additional savings.

“This system is very attractive to communities,” said James Reffelt, AES vice president of business development. “We take a problem disposal material, and turn it into a useful product, in an economical and environmentally sound manner – no risk to the community.”

Touted to be environmentally friendly, the system is said to reduce landfill loading, remove air emissions, and decrease related transportation costs. In some cases, as in Kingston, the waste methane gas available at the plant is used to run the drying process, and any excess is redirected to a generator to produce electricity, thereby creating additional savings for the community.
