Anaerobic Digestion: Green Gas or Green Wash?

On Sept 10th The Westminster Food & Nutrition Forum will bring together policymakers and key stakeholders to discuss the future of UK food waste policy. The afternoon session will focus on how to prioritise and expand the UK anaerobic digestion industry as part of the UK strategy to tackle food waste.

Anaerobic Digestion, has been promoted by government and industry as the ‘green solution’ to food waste.

At first glance, it appears to solve the problem of food waste by diverting it from landfill to produce renewable biogas energy & reduce greenhouse gas emissions simultaneously.

As dedicated food waste activists committed to following the Food Waste Pyramid, we are concerned that the expansion of anaerobic digestion to combat food waste is to the detriment of diverting food waste either to people or to pig feed and is not the green solution it claims to be.

We feel that government and industry should not be prioritising and expanding the UK anaerobic digestion industry as part of the UK strategy to tackle food waste because:

  1. Anaerobic Digestion does not tackle or address the systemic cause of food waste, particularly upstream in the food supply chain.
  1. Anaerobic Digestion is not an energy efficient or sustainable solution to food waste as it recovers less than 1% of the energy used to produce the crop.
  1. A large majority of the food waste being produced at the end point of the supply chain by supermarkets and retailers is avoidable and edible food ‘waste’, and therefore should not be directed to anaerobic digestion at all.

The expansion of an anaerobic digestion industry feeds into the current culture of waste system, whereby supermarkets and businesses are not incentivised to reduce or eliminate food waste as there exists an anaerobic digestion infrastructure that relies on its existence.

It will likely lead to an increase in food waste.

Join us tomorrow, September 10th at a peaceful protest banner drop where we will be telling the Westminster Food & Nutrition Forum to:

Feed Bellies Not Bins!!!  and to Feed Humans not Corporate Control!!!


Meet at 11am, Glaziers Hall, 9 Montague Close, London SE1 9DD
