'Garbage Guzzler' reduces waste from Oxford college's 500 daily meals

An Oxford college has chosen a Garbage Guzzler onsite aerobic food waste digester which is capable of reducing food waste by up to 90%.

Mansfield College produces more than 500 meals a day for its staff, students and visitors.

Each week the College was producing two wheelie bins full of food waste and this was identified as an area that could be improved upon, under their green initiative.

Using bacteria to help speed up the digestion process, the Garbage Guzzler from company PKL has been efficient and has rarely needed to be emptied in three months. When they do empty it, the college are using the remains of their food as nitrate-rich soil improver around their grounds.

Lee Browning, Kitchen Manager at Mansfield College, said: “The digestate looks a bit like old coffee grounds. The bacteria have just reduced the food so quickly. What has been brilliant is that we have less vermin around the bin store and fewer flies, as they don’t seem to like the Garbage Guzzler."
