Growing, raising, processing, and delivering food uses resources such as water, land, fuel, packaging, and more. These processes also contribute to air pollution and greenhouse gas emissions. When food spoils or is thrown away before we eat it, the resources that went into creating the food are wasted. The food takes up space in landfills and releases greenhouse gases as it decomposes, rather than nourishing people or helping alleviate food insecurity.
Wasted food is a problem across the country. National nonprofit ReFED estimates 35% of all food produced in the U.S. went unsold or uneaten in 2019. This food represents a $408 billion economic loss and contributes 4% of the total U.S. greenhouse gas emissions.
Preventing wasted food has:
- Economic impact: A family of four in Minnesota could save $1,200 a year by reducing their food waste.
- Environmental impact: Food makes up 18% of landfills in Minnesota, where it breaks down and produces methane, a greenhouse gas with heat-trapping potential 25 times greater than carbon dioxide. Reducing wasted food is a significant opportunity to mitigate climate change.
- Social impact: One in 12 households in Minnesota experiences food insecurity that could be alleviated by food rescue efforts.
Most thrown-out food could have been eaten
The majority of the food Minnesotans throw out — about 62% — could have been eaten or donated, an MPCA-commissioned study of solid waste in 2019 and 2020 found. The waste composition study is the first in-depth exploration of how much of each type of wasted food is in our trash, building upon a previous 2012-2013 study that looked more generally at the total proportion of food in Minnesota’s solid waste.
Food and compostable paper and packaging make up a quarter of everything households and businesses throw in the trash. Within that category:
- 40% is food that could have been eaten at some point before it spoiled
- 6% is unopened and unexpired food that could go to people in need
- 25% is inedible food scraps ideal for composting, such as vegetable peels and egg shells
- 24% is paper and packaging that can be composted alongside food scraps
The MPCA’s goal is to cut the amount of food wasted in Minnesota by half by 2030, using 2013 numbers as a starting point.
Help make a difference
Consider small changes in daily behaviors:
- Aim to buy only the amount of groceries you know you can eat.
- Save leftovers in the fridge or freezer instead of tossing them.
- Donate extra food to a local food shelf or food rescue program.
- Bring your food scraps to an organics collection site, participate in a curbside organics program, or compost them in your backyard.
