Every year, roughly one-third of all food produced for human consumption is lost or wasted. In the United States that translates to about 80 million tons of food per year — food that rots in fields, spoils in warehouses, gets trimmed and discarded in commercial kitchens, or sits in household refrigerators until it's past saving. The environmental cost is staggering: food waste is responsible for approximately 8% of global greenhouse gas emissions.

In Madison, Wisconsin, a growing coalition of organisations, businesses, and community members is working to make the local food system dramatically less wasteful — and in doing so, build a more resilient, connected, and equitable food economy. At the centre of much of this work is the concept of the Madison Food Loop.

What Is a Food Loop?

A food loop is a systems-level approach to food that aims to keep organic matter cycling through the local economy rather than ending up in a landfill. Think of it as applying the principles of circular economy design to the food system: surplus food gets redirected to people who need it; food that can't be eaten gets composted or converted to energy; the resulting compost feeds the farms that grow more food.

In practice, closing a food loop requires coordination between many different players: farms, food processors, grocery stores, restaurants, food banks, composting facilities, and municipal waste management. It requires trust, shared infrastructure, and often some form of community governance to align incentives across sectors.

Madison's Advantage: A Strong Food Culture Foundation

Madison is unusually well positioned to build a functional food loop because it already has so many of the required pieces in place. The Dane County Farmers' Market provides a direct producer-to-consumer channel that bypasses much of the waste inherent in industrial supply chains. The Willy Street Co-op and other independent grocers have long-established relationships with local farms. The University of Wisconsin runs extensive food systems research. And the city government has consistently invested in composting infrastructure and food recovery programmes.

Dane County's composting programme accepts food scraps from tens of thousands of households, diverting organic material from landfills and producing compost that returns nutrients to local farms. Several Madison restaurants participate in organic waste diversion programmes, separating kitchen scraps for pickup rather than sending them to landfill.

Food Recovery: Feeding People First

Before food can be composted, every effort should be made to get it to people who need it. The food recovery hierarchy — endorsed by the U.S. EPA — prioritises feeding hungry people above all other uses for surplus food.

Madison has a robust network of food recovery organisations. Second Harvest Foodbank of Southern Wisconsin operates one of the most efficient food bank systems in the country, rescuing millions of pounds of food annually from grocery stores, farms, and food manufacturers. Community fridges — publicly accessible refrigerators stocked by volunteers — have appeared in neighbourhoods across Madison, allowing individuals and restaurants to donate small amounts of food directly to neighbours.

"The best compost is the food you didn't throw away in the first place. The best composted food is the food that fed someone who was hungry." — Madison food systems advocate

Restaurants and the Food Loop

Commercial kitchens generate enormous quantities of food waste — from vegetable trim and bread ends to plate scrapings and dishes that don't sell before close. A restaurant committed to the food loop approaches this challenge systematically.

Progressive Madison restaurants are adopting a range of practices to reduce kitchen waste:

  • Whole-animal and root-to-stem cooking — using every part of an ingredient, including bones for stocks, stems for pestos, and citrus peels for infusions
  • Menu flexibility — designing menus that can incorporate surplus ingredients before they spoil
  • Staff meals — converting surplus prep into nutritious meals for kitchen staff
  • Donations at close — partnering with food rescue apps and local food banks to donate unsold prepared food
  • Composting — participating in Dane County's commercial organics diversion programme for any unavoidable food waste

The Technology Layer

Apps and digital platforms are increasingly important to food recovery efforts. Apps like Too Good To Go allow restaurants and bakeries to sell surplus food at a discount rather than discarding it at closing time. This creates an economic incentive to reduce waste that appeals to even the most budget-conscious kitchen manager.

Data also helps. Restaurants that track their waste by category and weight can identify patterns — is the chicken always left over on Mondays? Is the bread basket programme generating more waste than value? — and adjust their operations accordingly.

How You Can Participate in the Madison Food Loop

You don't need to run a restaurant or a farm to participate in Madison's food loop. Here are some entry points for individuals:

  • Sign up for Dane County's household food scraps collection programme if you live within the service area
  • Shop at the Dane County Farmers' Market and buy "ugly" or surplus produce
  • Volunteer with Second Harvest Foodbank or another food recovery organisation
  • Reduce your own household food waste by meal planning and proper food storage
  • Use the Still Serving Food tool to find restaurants still serving near closing time — eating up surplus inventory helps too

The food loop is not a single programme or initiative — it's a way of thinking about food that recognises waste as a design failure. When we close that loop, we reduce emissions, feed more people, and build a food system that's more resilient to the supply chain shocks that climate change will inevitably bring.
