GlobeNet : Renewable Energy Solutions for Wastewater Treatment

GLOBE-Net (August 19, 2009) – Nexterra Systems Corp., a Vancouver-based supplier of biomass gasification solutions, and ANDRITZ, an Austrian market leader for customized plants, process technologies, have formed a strategic alliance to market drying solutions fuelled by renewable biomass energy from municipal wastewater treatment plants.

The combination of Nexterra gasification technologies with Andritz biosolids dryers will enable municipal wastewater treatment facilities to reduce fuel costs, eliminate dependence on fossil fuels, lower their greenhouse gas emissions and deploy a sustainable solution for biosolids management.

According to the U.S. Environmental Protection Agency (EPA), there are more than 16,000 wastewater treatment facilities in the United States operated by municipalities, each of which produces biological sludge or “biosolids” as a residual product from the wastewater treatment process.

Traditional biosolids management methods include spreading dried sludge on lands or trucking it to landfills. Many municipalities wish to discontinue these practices due to health concerns, rising fuel and management costs, greenhouse gas emissions from transportation, and diminishing landfill capacity. They are looking for biosolids management solutions that will enable them to reduce energy costs and carbon emissions.

During the first phase of their strategic relationship, ANDRITZ and Nexterra will target facilities where existing biosolids dryers can be retrofitted with Nexterra’s biomass gasification technology, and will use biomass fuel to replace natural gas as a heating source. The companies plan also to offer technology solutions for greenfield sites that combine ANDRITZ biosolids dryers and Nexterra gasifiers.

“This strategic relationship with ANDRITZ provides us with a partner who has a deep understanding and presence within the wastewater treatment market, which we see as a very significant market opportunity for our gasification technology,” said Jonathan Rhone, President and CEO of Nexterra. “Our vision is to offer municipalities a seamless range of renewable energy solutions for drying biosolids, and eventually for power generation with gas engines.”

Nexterra is developing a biomass to combined heat and power solutions (CHP) with General Electric, to be sized at 2 – 10 MW, that combine Nexterra’s gasification technology and gas conditioning equipment with high efficiency gas engines. This will enable municipalities to self-generate renewable heat and power on-site.
