How Much Food Ends Up In Landfills Each Year?

Roughly one-third of all food produced globally for human consumption is wasted, and most of it ends up in landfills. In the United States alone, the Environmental Protection Agency (EPA) estimates that about 60 million tons of food waste are sent to landfills every year. That is enough to fill over 100 football stadiums. This waste makes up more than 20% of all landfill content, making it the single largest category of material buried in the ground.

What Causes Food to End Up in Landfills?

The path from farm to table has many points where food gets lost or thrown away. On farms, crops are left unharvested because they do not meet cosmetic standards for shape, size, or color. Supermarkets reject these “ugly” fruits and vegetables, even though they are perfectly safe to eat.

Grocery stores also throw away food that is close to its sell-by date. Many stores remove items from shelves days before they actually spoil. Restaurants and cafeterias overprepare meals and discard what is not eaten. At home, people buy too much, cook too much, and forget about leftovers in the back of the fridge. The Natural Resources Defense Council (NRDC) reports that the average American family throws away roughly $1,500 worth of food each year.

Most of this waste goes into household trash bins and then to municipal landfills. Unlike compost, food buried in landfills does not break down cleanly. It rots without oxygen and produces methane, a greenhouse gas over 25 times more potent than carbon dioxide.

How Much Food Ends Up In Landfills Each Year by Country?

The numbers vary widely by country, but no nation does well. The United Nations Environment Programme (UNEP) publishes a Food Waste Index Report that tracks this data. In the United States, the figure is roughly 60 million tons annually. China generates around 90 million tons of food waste per year, though a larger portion comes from processing and distribution rather than households.

In Europe, the European Commission reports about 88 million tons of food waste each year. Countries like Germany and France have lower household waste rates due to stronger prevention policies. France, for example, passed a law in 2016 that bans supermarkets from throwing away unsold food. They must donate it to charities instead.

Developing countries lose food mostly at the beginning of the supply chain. Poor storage, lack of refrigeration, and bad roads mean crops rot before reaching markets. In sub-Saharan Africa and Southeast Asia, post-harvest losses can exceed 40% for certain fruits and vegetables. The total global food waste figure is estimated at 1.3 billion tons per year, according to the Food and Agriculture Organization (FAO).

How Does Food Waste in Landfills Affect the Environment?

When food sits in a landfill, it decomposes without oxygen. This process is called anaerobic digestion, and it produces methane gas. Landfills are the third-largest source of human-caused methane emissions in the United States. The EPA states that municipal solid waste landfills released over 100 million metric tons of carbon dioxide equivalent in methane in 2020.

Methane traps heat far more effectively than carbon dioxide over a 20-year period. That means food waste in landfills is a major contributor to climate change. If global food waste were a country, it would be the third-largest emitter of greenhouse gases after China and the United States.

There is also the wasted water and energy used to grow, transport, and package that food. The NRDC estimates that producing the food Americans throw away each year uses 30 million acres of land and 4.2 trillion gallons of water. That is enough water to fill Lake Tahoe twice.

What Actually Works to Reduce Food Waste Going to Landfills?

Composting is the most straightforward solution for household food scraps. When food decomposes with oxygen in a compost pile, it produces carbon dioxide instead of methane. That is still a greenhouse gas, but it is far less harmful. Many cities now offer curbside compost collection, and backyard compost bins cost very little.

Food donation programs also keep edible food out of landfills. Organizations like Feeding America coordinate with grocery stores and restaurants to redirect surplus food to people who need it. The EPA’s food recovery hierarchy places feeding people as the highest priority after source reduction.

Some municipalities have started using anaerobic digesters at wastewater treatment plants. These machines break down food waste in a controlled environment and capture the methane to generate electricity. The leftover material becomes fertilizer. This technology is expensive, but it works.

Consumer behavior changes matter too. Planning meals before shopping, storing food correctly, and eating leftovers can cut household waste by 30-50%. The NRDC has a free guide on proper food storage that shows how long common items actually last. Many people throw away food that is still safe to eat because they misread date labels.

Common Misconceptions About Food Waste in Landfills

One widespread myth is that food breaks down naturally in landfills and returns to the soil. This is false. Landfills are designed to be dry and airtight to prevent groundwater contamination. Nothing decomposes quickly in there. Archaeologists have found hot dogs and newspapers still readable after 40 years in a landfill.

Another misconception is that biodegradable packaging solves the problem. Even if a package is labeled biodegradable, it will not break down in a landfill any faster than regular plastic. The conditions needed for biodegradation — oxygen, moisture, and microbes — are absent in most landfills.

Some people believe that food waste is only a problem for wealthy countries. As the table above shows, developing countries lose massive amounts of food too, just at different stages. The total volume of waste in Sub-Saharan Africa is actually higher than in the United States, though it comes from spoilage rather than consumer behavior.

What to Avoid When Trying to Reduce Food Waste

Do not rely on “sell by” or “use by” dates as the sole indicator of whether food is still good. These dates are manufacturer suggestions for peak quality, not safety. The USDA states that many foods remain safe to eat past these dates if stored properly. Use your senses — smell, look, and taste — before throwing anything away.

Avoid buying in bulk unless you have a plan for using everything. Bulk purchases often lead to more waste because people cannot finish the food before it spoils. This is especially true for fresh produce and dairy products.

Do not assume that all food waste must go to the trash. Many scraps can be used for other purposes. Vegetable peels and ends can make stock. Coffee grounds can go into garden soil. Eggshells can be crushed and added to compost. The goal is to keep organic material out of the landfill entirely.

• Plan your meals for the week before shopping.
• Store fruits and vegetables correctly to extend their life.
• Freeze leftovers or extra portions before they spoil.
• Compost scraps instead of throwing them in the trash.
• Donate non-perishable items you will not use.
