When disposed of in landfill, food waste releases methane, a relatively damaging greenhouse gas, and leachate, a toxin capable of considerable groundwater pollution.
This approach could contain greenhouse gas levels to less than 450 parts per million, the safe level beyond which climate change becomes catastrophic and irreversible.
As a result, the displacement of existing agricultural production was likely to lead to reductions in biodiversity and possibly increases in overall greenhouse gas emissions.
