Food Waste Treatment

Food waste is the 2nd largest waste stream disposed of for incineration. A trial project to co-digest food waste and used water sludge has shown that the biogas produced is three times more than digesting used water sludge alone.

Co-digesting food waste with used water sludge is one of the future solutions to convert food waste into useful products and support Singapore’s vision to work Towards a Zero Waste Nation and a circular economy.
