About us

Feedback is a London-based campaign group that works to regenerate nature by reducing the demands placed on it by the food system.

Founded in 2013, we are best known for our work on food waste.  Our campaign style is unique, and we have over the years successfully combined hard-hitting investigative research, mass public participation public feasts and on the ground pilots for a better food system to put the issue of food waste at the very top of the business and policy agendas.

Having diagnosed food waste as a symptom of a dysfunctional food system, and with the arrival of a new Executive Director, Carina Millstone, we last year conducted a strategic review to understand the changes to the food system that would be required for a waste-free system.

This has led us to expand our areas of work to include other specific themes within the food and proximate systems, including meat, aquaculture, sugar and  ‘green’ energy generated through anaerobic digestion, as well as developing a broader critique of the globalised, financialised, food system, and piloting its alternative through our regional food economy programme.

Our model for a sustainable food system

At Feedback, we understand that food waste is a symptom of our broken food system. To fully address food waste we need to build a better food system; one that is circular, low-input and stable. Read more about our model for a better food system here.

What we do

We are unique in combining high-profile, innovative and inspiring public campaigning with hard-hitting research and expert advice on food waste reduction, which we communicate to decision-makers across government, business and the third sector. We specialise in shining a light on the hidden causes of waste across the food supply chain. We work to raise the profile of existing initiatives that offer the solutions to food waste; where solutions do not currently exist, we catalyse the creation of new organisations and projects to implement them.

With a track record of changing the policies of some of the world’s biggest food companies and reaching out to millions of people through our projects, our innovative campaigning style has helped to elevate food waste from a non-issue several years ago to one now recognised as an urgent international priority.

Currently our food system is the single biggest problem standing in the way of tackling climate change, biodiversity loss and other major environmental problems. That’s why we are working towards a circular, stable, low-input food system.

Our story so far 

Feedback is built on over a decade of food waste campaigning by Tristram Stuart and the Feedback team. After years of instigating mass media coverage of the issue – principally by taking journalists and broadcast media round the back of supermarkets to uncover the extent of the food waste scandal – Tristram published his book, Waste: Uncovering the Global Food Scandal (Penguin, 2009) and soon after organised the first Feeding the 5000 event in London’s Trafalgar Square in December 2009. With the extensive media outreach and public support for the initiative, the event had immediate impact on government and business policy and promoted the activities and messages of the partner organisations, including FareShare, This is Rubbish, ActionAid and Save the Children. Since that date Tristram and the Feedback team have played a pivotal role in catalysing the food waste movement in the UK and around the world.
