An Indiana company is planning to build a facility in Cedar Lake that uses algae to treat municipal wastewater. The process creates a sludge that byproduct that can be utilized to produce electricity, heat and biofuel. Indianapolis-based Algaewheel, Inc. President Chris Limcaco says the system uses about half the energy of a conventional wastewater treatment plant. He says a pilot system has been in plane in Whitestown since 2004. It has confirmed energy savings in electrical costs and the treatment of the water is as good or better than a traditional facility. Limcaco says a groundbreaking on the Cedar Lake project should take place this year. It would be the first municipal wastewater treatment plant to use the company's algae technology.
