An alternative strategy for disposing of fallen stock in the UK called bioreduction is being investigated by researchers at Bangor University in North Wales to see if it could help reduce costs, as well as improve biosecurity on pig farms.

Bioreduction is the process of accelerated decomposition of animal carcases in an aerated vessel containing water at 40°C. The waste within is subsequently disposed of via incineration, or rendering, at a convenient time for the farmer.


In a project that is being funded by the British Pig Executive (BPEX), Ceri Gwyther at Bangor University is investigating the potential of this process to reduce the costs of livestock disposal (the volume of waste considerably decreases) and cut the frequency of farm collections needed by licensed contractors.
