Food waste is a global problem costing billions and contributing to greenhouse gas emissions. Turning that waste into cooking gas is increasingly being seen as a solution for homes and businesses.
Although creating biogas at home is not a "panacea" for our food-based emissions, it is one potentially valuable piece of the puzzle, according to the authors of a 2019 Australian study.That study
However, that included some days where no gas was used, and others where up to two hours of gas supply was used. Like Annett and Paul, Ned lives on an off-grid property near the Hawkesbury River in New South Wales and creates his own biogas."The bladder where the gas is stored lasts about two and a half hours' run time."
He says their system doesn't produce enough gas to supply all their cooking needs, but it's excellent as a backup and for diverting waste from landfill."We're a family of five — three little kids — the amount of gas cooking we do is probably more than we'd be able to generate on purely residential food waste consumption.
