HDS Intl to build anaerobic digester in Saint John, Canada

Dec 4, 2012 - US eco-sustainability solutions provider HDS International Corp (PINK:HDSI) today said it had signed a seven-year deal with the City of Saint John in Canada to install an anaerobic digester waste-to-energy system there.

The facility will be developed at the city's Lancaster wastewater treatment station and will draw biosolids and sludge directly from raw wastewater. The biowaste, together with other biodegradable materials, will be processed by the digester, producing biogas, energy and other byproducts, HDS International said. The company plans to use its carbon dioxide capture and reutilisation technologies in the project, which is to cut the operating costs of the city of Saint John.

According to preliminary calculations, the site can accommodate a biogas installation producing up to 5 MW of power.

HDS International will also conduct a feasibility study that will assess the possibility of removing carbon dioxide from pre-combustion biogas; producing algae biomass in the Lancaster lagoon using wastewater nutrients and recycled carbon dioxide; and supplementing digester biomaterial with algae to increase biogas production.

Furthermore, via the contract HDS International will get exclusive rights to any municipal digester project in Saint John for a seven-year period.
