Our waste-to-energy (WTE) plant receives trash identified as un-recyclable and converts it at 2,000 degrees Fahrenheit to energy in the form of electricity. The ecomaine WTE plant processes about 175,000 tons of trash a year and, from that process, generates enough steam to create about 100,000 megawatt-hours of electricity annually. That’s enough electricity to power our WTE and recycling facilities, our company’s electric vehicles, plus about 15,000 homes for a year!
Converting the trash to energy also benefits the communities we serve by reducing its volume by 90 percent, leaving only inert ash to be stored at the landfill site. (There are also statewide economic benefits from WTE plants; click here to read the results of a Maine study).
ecomaine‘s state-of-the-art WTE plant opened in 1989 and operates around the clock, every day of the year, with the exception of an annual two-week shut down for planned maintenance. The building was designed with negative pressure to trap any odors inside and to re-circulate that air for boiler combustion. Because the air is filtered, office space for ecomaine staff is also located in the same building.
Though combusting trash to generate electricity can generate pollution, ecomaine’s Environmental Management System mitigates much of the harmful materials, and is certified under the international ISO 14001 standard.
