Powerful manure

New Zealand-based company Flotech Inc. will soon open its first biogas upgrading system, which converts manure into natural gas, in Canada at an Abbotsford farm southeast of Vancouver. Flotech has a water-scrubbing system that converts unrefined “biogas” emitted by agricultural waste into natural gas clean enough for use in homes. Flotech’s Greenlane Biogas water scrubber installed at the British Columbia farm has the capacity to process 46 standard cubic feet per minute – the equivalent of about 1.5 megawatts of electricity or enough to heat about 1 homes.
