Kitchen compost scheme could prevent thousands of tonnes of carbon per year
She said that number, extrapolated out to a city-wide collection scheme, was “a game changer”. “Initial results for the trial show it would divert 3000 tonnes of food waste to landfill per year … and prevent production of 2850 tonnes of methane and approximately 1500 tonnes of carbon dioxide.” Organic waste produces methane when it degrades in an anaerobic environment like a landfill, a gas which Parfitt said was “at least 16 times more damaging than carbon dioxide”. When composted properly, food waste does not produce methane – the microbes which produce methane are not ...
