"We’ve also had some glitches with the new food waste collection vehicles which hasn’t helped. The collections of food waste take place on the same day that people’s grey and green bins are currently emptied. If your bin is emptied on Wednesday, for example, so too will your food waste caddy. The aim behind the introduction of the separate collections is to stop heavy, moisture-rich food waste going either for incineration or to landfill, which in turn will lower harmful greenhouse gas emissions. The food waste itself will instead be transformed into renewable forms such as biogas fuel or bio-fertiliser for use in farming.
