Canary Islands turns waste into energy

摘要

As a collection of islands totaling only 2875 square miles, disposal of wastewater land solid waste is an environmental and political issue throughout the Canaries. One solution is the new Salto del Negro municipal waste treatment plant in Las Palmas de Gran Canada. The plant processes garbage and sewage collected from Las Palmas de Gran Canaria, a city of 380,000, as well as from several surrounding towns and villages. The waste is processed in a digester which produces methane gas. The gas is used in turn to fuel generators that produce both electricity and heat. The combined heat and power (CHP) system was manufactured by Cummins Power Generation.
