Tech to cut food waste

Marc Zornes, Winnow Founder & CEO

We are on a mission to inspire others to see that food is too valuable to waste.

  • Winnow offers digital tools that help commercial kitchens halve their food waste, saving up to 8% of their food spend. For example, one application has a camera and software to identify food being thrown away. They are a certified B Corporation, that is, they meet certain social and environmental standards to balance profit and purpose.
  • Marc founded Winnow five years ago, following a career at McKinsey & Company where he co-authored a report highlighting food waste as a huge issue that was not being tackled.
  • One-third of all food (1.3bn tons) is wasted each year and that loss is responsible for 8% of greenhouse gas emissions, according to the United Nations. One of the UN's sustainable development goals (12.3) is to halve per capita food waste by 2030.
  • After five years, Winnow is being used in almost 40 countries, with clients including Compass Group, Accor Hotels and IKEA. They say they've saved their customers over $30m per year in reduced food waste – their goal is to reach $1bn per annum by 2025.
  • Marc and Winnow are recognised as leaders in their field with various accolades including a Circular from the World Economic Forum and an FT Transformational Business Award.
