Indiana Company to Submit Proposal to Utilize Algae to Treat Wastewater and Create Renewable Energy

CROWN POINT, IN--(Marketwire - June 12, 2008) - Ewire -- Algaewheel, Inc. announced today that they will be submitting a proposal to build a facility in Cedar Lake, Indiana that uses algae to treat municipal wastewater and uses the sludge byproduct to produce electricity, heat, and biofuel. Christopher Limcaco, President of Algaewheel, announced that Algaewheel has partnered with Thieneman Construction to develop and design the proposal. Algaewheel President Christopher Limcaco praised town officials for their forward-thinking and responsible leadership, stating, "Cedar Lake officials are demonstrating both fiscal and environmental awareness by soliciting the proposal, and Algaewheel is excited about the opportunity."

The continued growth of Cedar Lake has necessitated the construction of a new wastewater treatment facility. The new facility will be capable of treating an estimated 2.25 million gallons of wastewater per day, and will serve the residents on the west side of Cedar Lake. Algaewheel's bid will be submitted by July 7th, 2008, and the successful bidder should be identified by September 7th, 2008. Construction of the new facility should begin this year and be completed by the end of 2009.

The groundbreaking facility would include a patented type of algae production. Invented by Algaewheel's President, Christopher Limcaco, the process uses specially designed wheels that maximize algae production and automatically harvest the algae. The wheel, which has been in development for 13 years, quadruples the surface area available for algae production as compared to a stationery algae tank, which significantly reduces the footprint of the facility.

The algae are a component of the system that treats and filters the wastewater by removing certain contaminates, such as phosphorous, and breaking down solids. According to Limcaco, "The system is basically an algae farm using the wastewater as fertilizer." The resulting sludge is a mixture of wastewater solids and algae. This mixture is then thermally treated using a process similar to gasification, a technology that has been around for years. During the thermal process, oils are removed from the sludge mixture in stage one, and the remaining solids are gasified to produce electricity and high grade fertilizer in stage two.
