FOOD RECYCLING How many times have you tossed out milk leftovers or other food from the refrigerator because it was starting to go bad According to a study by the USDA U S Department of Agriculture Americans throw away about 96 billion pounds 43 5 billion kilograms of food each year This figure includes food thrown out by U S supermarkets restaurants and households Supermarkets throw out a lot of food because it's about to spoil and it can't be sold Restaurants often throw away perfectly good food that customers didn't order or didn't eat The situation is the same in other wealthy nations In a world where millions of people face hunger on a daily basis the loss of so much food is a tragedy But people are fighting the problem on many fronts Some supermarkets send discarded fruits and vegetables to recyclers who turn the food into nutrient rich compost decayed organic matter The recyclers then send the compost to farmers who use it as fertilizer Some supermarkets send leftover yogurt directly to farmers who feed it to hogs and other livestock animals Sometimes supermarkets must discard food that is perfectly safe to eat For instance food cans and boxes sometimes get damaged at stores and warehouses Supermarkets can't sell the packages even though the food inside them is safe In that case markets usually donate the food to organizations that help needy people Many colleges and high schools have cut cafeteria waste by serving food on dinner plates rather than on trays Since plates hold less than trays students are less likely to pile up food that may not be eaten As a result they throw away less food Studies have shown that when students stop using trays schools reduce food waste by 30 percent or more Numerous universities have also built their own composting sites to turn dining hall food waste into fertilizer
