Food recovery is the practice of collecting surplus food that would otherwise go to waste and redirecting it to a better use, whether that means feeding people, feeding animals, or converting it into compost or energy. In the United States, roughly 30 to 40 percent of the food supply goes uneaten, amounting to about 133 billion pounds of food lost at the retail and consumer levels alone. Food recovery aims to recapture as much of that surplus as possible before it ends up in a landfill.
The Food Recovery Hierarchy
The EPA ranks food recovery actions from most to least preferred, giving organizations a clear framework for deciding what to do with surplus food. The tiers, from best to worst, are:
- Source reduction: Preventing surplus from being created in the first place, through better purchasing, menu planning, or inventory management.
- Feed hungry people: Donating edible surplus to food banks, shelters, and community organizations.
- Feed animals: Directing scraps and off-spec food to livestock or animal feed operations.
- Industrial uses: Converting waste into fuel, such as turning fats and oils into biodiesel or using anaerobic digestion to generate energy.
- Composting: Breaking down organic material into nutrient-rich soil amendments.
The logic is straightforward: preventing waste is better than managing it, and feeding people is better than feeding a compost pile. Each tier captures value that would otherwise be lost.
Why Food Recovery Matters for the Environment
Food waste makes up about 24 percent of everything dumped in U.S. municipal landfills. When that food decomposes underground without oxygen, it produces methane, a greenhouse gas far more potent than carbon dioxide over the short term. An estimated 58 percent of the methane that escapes from municipal landfills into the atmosphere comes specifically from decomposing food. Municipal landfills are already the third-largest source of human-caused methane emissions in the country, and EPA data shows that while total landfill emissions are declining, methane from food waste is actually increasing.
Recovering food before it reaches a landfill cuts directly into those emissions. It also saves the water, energy, and land that went into growing, processing, and transporting food that nobody ate.
The Hunger Connection
In 2024, 47.9 million people in the United States lived in food-insecure households. Meanwhile, tens of billions of pounds of perfectly edible food get thrown away each year. Food recovery bridges that gap by redirecting surplus from restaurants, grocery stores, farms, and manufacturers to organizations that serve people who need it.
Donations of perishable prepared foods, typically collected from restaurants, caterers, hotel kitchens, corporate dining rooms, and college campuses, require special handling. Refrigerated trucks, insulated coolers, and prompt distribution are all part of the process. Cold foods need to stay at 41°F or below, and hot foods at 135°F or above, from the moment they leave the donor’s kitchen until they reach the person eating them. Organizations that handle donated food keep records tracking what was donated, when it was transported, and at what temperature it was stored.
How Gleaning Works
One of the oldest forms of food recovery is gleaning: harvesting crops that farmers leave behind after commercial picking is done. Sometimes the produce is cosmetically imperfect, sometimes there’s simply more than the market will absorb, and sometimes a portion of the field wasn’t worth the labor cost to harvest commercially.
The USDA recommends that gleaning organizers contact farmers during non-harvest months, when they have more time to consider participating. Once a farmer agrees, coordinators confirm the exact pickup time and location, the number of crates or boxes needed, where vehicles should park, and the farmer’s preferred collection method. Volunteers arrive on time, handle produce carefully, and follow the donor’s instructions. Farmers can get frustrated when gleaners damage crops or treat the donation carelessly, so respect for the operation matters as much as logistics.
Legal Protections for Donors
A common reason businesses hesitate to donate surplus food is fear of being sued if someone gets sick. The Bill Emerson Good Samaritan Food Donation Act addresses that directly by providing federal protection from civil and criminal liability for food donors, as long as they act in good faith and the food isn’t handled with gross negligence or intentional misconduct.
The law was expanded in January 2023 to cover more situations. Three groups now receive protection:
- Persons and gleaners who donate to a nonprofit that distributes food to people in need at no cost or at a reduced price.
- Nonprofit organizations that receive and distribute donated food at no cost or a reduced price.
- Qualified direct donors who give food directly to people in need at no cost.
The 2023 update also clarified that nonprofits can charge a nominal fee when passing food to another nonprofit, as long as the person who ultimately receives the food pays nothing or only a reduced price. These protections remove one of the biggest barriers that kept grocery stores, restaurants, and caterers from donating their surplus.
The Business Case
Food recovery isn’t just charitable. It saves money. A large-scale analysis by the World Resources Institute and WRAP evaluated cost and benefit data from 1,200 business sites across 700 companies in 17 countries. Nearly every company saw a positive return on its investment in reducing food waste. Half of them realized a 14-fold return or greater, meaning every dollar spent on things like staff training and better production processes saved at least $14.
For businesses that can’t prevent all their surplus, donating rather than paying for waste hauling also reduces disposal costs. Some states offer tax incentives for food donations, adding another financial reason to participate.
Technology Connecting Donors and Recipients
One of the practical challenges in food recovery is timing. Surplus food appears unpredictably, and it spoils quickly. Technology platforms have emerged to solve this coordination problem. Food Rescue US, for example, runs a web-based app that connects food donors, volunteers, and social service agencies. The platform creates a schedule of local food rescues that volunteers can claim and complete, essentially turning surplus food into a logistics problem that anyone with a car and a free hour can help solve.
These platforms make food recovery scalable in a way that phone calls and standing appointments never could. A restaurant that unexpectedly has 50 extra meals after a catering cancellation can post the surplus and have a volunteer pick it up within hours.
How Food Recovery Differs From Food Recycling
The terms can blur together, but they refer to different parts of the hierarchy. Food recovery generally means rescuing food that is still edible and getting it to people or animals. Food recycling refers to the lower tiers: composting, anaerobic digestion, and other industrial processes that extract value from food that’s no longer fit to eat. Both matter, but recovery captures far more value. A pound of chicken donated to a food bank feeds a family. That same pound composted only returns nutrients to soil. The hierarchy exists precisely to push organizations toward recovery before recycling.
