Biorem ramps R&D in air emissions control

Ontario-based Biorem (TSXV:BRM) said today it secured a C$720,000 (US$673,000) contract for the newest version of its advanced biofiltration technology.

The two-stage air emissions control system is expected to remove potentially deadly chemical compounds that also cause odors at a municipal wastewater treatment facility in southern British Columbia. It’s one of more than 30 equipment contracts the company has signed this year in North America, plus about five in China.

But the company is also pursuing an application for its bacteria-based filtration technology that could be even more lucrative: absorbing harmful emissions from industrial processes, CEO Peter Bruijns told the Cleantech Group today.

“The air emissions regulations are only going to get stronger, especially as they pertain to greenhouse gas emissions worldwide,” Bruijns said. “We’re redirecting the company from purely odor control to also addressing air emissions.”

Bruijns said Biorem is in the final stages of developing a new proprietary system to clean air emissions using the same biological process. Depending on the speed of research and development, Biorem could have the process ready in about six to eight months, Bruijns said.

“It would displace thermal oxidizers than burn oxygen to destroy volatile organic compounds,” he said.

Chi Sage to globalize Chinese heat-pump tech

Philadelphia, Pa.-based Chi Sage Systems is commercializing a technology to reduce the waste of energy and water in typical heating, ventilation, air-conditioning and refrigeration (HVAC_R) systems in homes and commercial buildings.

CEO Moti Levi told the Cleantech Group the startup put a spin on the typical heat pump technology, which is extremely efficient but limited to places with underground hot water.

Chi Sage’s proprietary system uses highly efficient heat pump technology that can find a heat source from any type of water, including ocean water, lake water, or even sewage. That variety of sources opens up the possible applications for the technology, including major cities, Levi said.

In addition to energy efficiencies, Chi Sage’s system eliminates the need for a cooling tower, reducing water waste.

Chi Sage bought the intellectual property rights to the technology from China-based Jin Da Di, which installed a 9 megawatt system at the Beijing Southern Railway Station in 2008. Jin Da Di still holds the rights to develop the technology in China, while Chi Sage plans to commercialize it in the rest of the world.

“A lot of people talk about technologies going to China, but this is innovation coming from China,” Levi said.

Already, …
