Georgia-based Great Lakes Biogas Technologies has entered into an agreement with Canada-based Zero Waste Biogas Systems Inc. to market its waste compaction technology.

Bruce Coxhead, chief operating officer of Great Lakes Biogas Technologies and president and chief executive officer of Zero Waste Energy Systems, said the Revolution Compactor will now be exclusively licensed to Great Lakes Biogas Technologies. The company will strive to globally market the technology, which has been present in Canada for five years.

The Revolution Compactor is designed to remove liquids and air from waste prior to being loaded and transported, considerably reducing transportation costs and the need for landfill space. It has a 50 to one compact ratio for plastics, according to the company.

Coxhead said the compaction technology was developed in the United Kingdom. The company has performed 320 installations in several fortune 500 companies in the U.K. and France.

Earlier this year, Great Lakes Biogas Technologies received a license to market Zero Waste's high-energy output thermophilic anaerobic digestion technology, which was originally developed by EEC Energy Ltd. in Canada. Coxhead said coupling the two technologies, in some applications, could be highly beneficial.

"The compactors are used for specific purposes, such as at a soda manufacturer or shampoo company," Coxhead explained. "The compactor separates the liquid stream-which may be used as feed in the anaerobic digester-from the packaging, which may be polyethylene or polypropylene. It also does product destruction, such as destroying off-spec car parts for a car manufacturer so they don't end up being retrieved from a dumpster and sold on the black market."

The anaerobic digestion technology has a very modular design, and is ideal for several industry applications such as dairy/beef cattle farming and the vegetable industry, Coxhead said. "Any that have an organic byproduct can use this digester on-site, and generate methane gas for supplementing their own natural gas," he said. "They can also make electricity-or if they large a large volume, put the electricity back on the grid."

Coxhead said Great Lakes Biogas Technologies hopes to expand the technologies worldwide. "We want to reach industries we haven't served before, and increase awareness of recycling in Canada and the United States, especially in reducing the amount of liquids going to landfills," he added.
