All About Food Waste

Americans throw more than $15 billion worth of food away every year, according to a new report from the Natural Resources Defense Council (NRDC). Why would we do this? Can’t we just recycle all our trash? And what about the food that spoils in the fridge instead of being eaten? The problem of food waste goes beyond what we throw out. Recent studies show that nearly 25 percent of our nation’s food is lost or wasted.

Food waste is a hot topic right now — from corporate giants like Walmart to tiny mom-and-pop stores. There are lots of reasons for this, but it boils down to the simple fact that a lot of food is thrown away each year in the U.S. (About 40 percent of all food produced in the country is thrown away or donated to charities.) In fact, food waste is estimated to cost the U.S. $218 billion in production losses.

Food waste is a big problem in North America. In fact, one of the biggest contributors to greenhouse gas emissions is food waste, which is estimated to be the equivalent of about 70 pounds of carbon dioxide in the atmosphere for every food item that is thrown away.

We throw away approximately 20-25 percent of the food we buy for the house. Food waste has serious implications for our own and others’ health, as well as the health of the world.

Pick up 5 bags of goods from the supermarket shop. Then go to the trash with one bag in hand.

Umm… what?

Yes, about 20-25 percent of the food bought for the household is wasted. This translates to 1.3 pounds of food thrown away per day, or 474.5 pounds each year.

Food waste has serious implications for our own and others’ health, as well as the health of the world.

“A Buddhist idea known as mottainai urges… us to be thankful for the resources we have, to respect them, and to utilize them with care. It also urges us not to squander.” Wangari Maathai, Nobel Laureate

What is the definition of food waste?

Food is regarded as a throwaway commodity in the industrialized world.

While none of us thinks that burning a rainforest is a desirable idea, wasting food adds to the destruction of one. We could relieve strain on the world’s surviving natural ecosystems if wealthy countries didn’t squander so much food.

Food is lost as a result of the food system.

Some food is lost on the farm and in the farm-to-retail chain…

Agricultural and post-harvest operations

  • Weather-related, disease-related, and predation-related losses occurred prior to harvest.
  • Mechanization, production methods, and choices have all resulted in harvest losses.
  • Insects, mould, degradation, shrinkage, and spoiling can cause storage losses.
Wholesaling and processing

  • Bones, blood, peels, pits, and other inedible parts are removed.
  • Throw away any goods that aren’t up to par (bruised fruit, etc.)
  • In-storage shrinkage
  • Package failure due to poor handling
  • Losses due to transportation
Estimating and Addressing America’s Food Losses, Jan-Apr 1997, Kantor LS, et al.

Food waste is almost often the result of an excess of food. Humans have ignored sustainable resource usage throughout history, even when resources were plentiful.

The United States has the largest food surplus of any country. We have 200 percent of an average adult’s energy needs — between 3,500 and 3,900 kcal per person are accessible. This is more than a typical adult needs. According to experts, a 130 percent excess, or approximately 2,700 kcal for most people, is sufficient.

So, what are we going to do with the surplus?

We may keep it, eat it, or throw it away. And we can only keep excess for so long before we have to dispose of it. Rich nations now divert excess food resources to farm animals, garbage cans, and their own overweight bodies.

What is the significance of food waste?

There’s a plenty of it.

In the U.S., where there is a significant food surplus, between 25% and 50% of all food is wasted (depending on sources & estimates).

If 5% of this could be recovered, it would provide enough food for 4 million people for one day. If 25% of the food was retrieved, there would be enough food to feed 20 million people – Sri Lanka’s entire population.

Since 1974, food waste per person has increased by 50%. Every day, 1400 calories of food are wasted per person.

Similarly, about 20 million tonnes of food waste are generated in the United Kingdom each year.

Others are starving.

The paradox is that global food insecurity has reached new heights, with almost 1 billion people going hungry. Food costs are continuing to rise in many parts of the world, and even in wealthy North America, there are record numbers of people using food banks.

Food waste is a waste of resources.

40% to 50% of the produce that is ready for harvest is never consumed. It may be damaged in transportation, thrown out because of its look, not sold in the shop, or not eaten at home. Foods that do not meet specific aesthetic criteria, such as size, shape, or color, are discarded. As a result, a perfectly excellent apple may be discarded because it has a little blemish on it.

Fruits and vegetables account for 28% of the waste generated by merchants and consumers.

Food waste is costly.

Food waste costs the United States $48 billion each year.

Food waste equates to a waste of other resources.

When we purchase more food than we need, we destroy land and resources that might otherwise be utilized to feed the world’s poor. Here are some more things we throw away:

  • Food waste now accounts for more than a fifth of overall freshwater use, according to experts. Wow. The current amount of food waste in the globe equates to a loss of about 675 trillion litres of water. That’s enough to meet the daily requirements of 9 billion people on 200 liters of water. See All About Drinking Water for additional information on water waste.
  • Other food: Between 40 and 60 percent of the fish harvested is discarded. This is referred to as by-catch. Many of the fish are edible, but have yet to be commercialized. See All About Eating Seafood for additional information on fish waste.
  • Food waste consumes more than 300 million barrels of oil each year, putting the environment at risk (4 percent of total U.S. oil consumption). There are environmental repercussions when we throw food away: organic materials end up in landfills, degrade, and generate methane, a greenhouse gas. Landfills account for around 33% of methane emissions in the United States. Methane has a 20-fold greater environmental impact than carbon dioxide. This methane has the potential to be utilized as biogas.

Food waste leads to a slew of other societal issues.

When we purchase food and then throw it away, we decrease the total supply and raise food costs. Food becomes more expensive for people who are impoverished and malnourished in other areas of the globe as a result of this. As seen in the diagram below, it also causes additional issues.

going hungry consequences of the food crisis

Food scraps and livestock feed are going to the dogs.

Do you recall the case of the mad cow disease? This arose as a result of manufacturers utilizing leftover animals in cattle feed, causing herbivores to cannibalize one another.

We breed animals to consume their flesh, but what about their livers, kidneys, brains, tongues, and feet, among other organs? People have been using these items for millennia. However, we increasingly utilize them as components in pet and animal food in the wealthy world.

Offal consumption has dropped by half in the past 30 years, with the viscera and trimmings of a slaughtered animal generally deemed inedible by humans. In essence, we consume the parts of animals that we like and discard the rest. There’s more to chicken than skinless breasts.

In addition to “excess” meat, agricultural animals consume almost 40% of world cereals (this is higher in the U.S.). This does not include the other foods consumed by animals.

We feed animals more than three times the amount of food we give them in the form of milk, meat, and eggs. In other words, the crops fed to livestock lose 70% of their calories.

When food is given to farm animals, we are clearly not throwing it away, but it is wasteful in a world with almost 7 billion humans. People in a worldwide democracy would very certainly demand the abolition of fattened animals merely because of their inefficiency.

Conclusions and suggestions

“There are almost a billion hungry people on the planet, yet with less than a fourth of the food wasted in Europe and North America, they could all be fed. We are pulling food out of the mouths of the poor in a globalized food system, where we all purchase food in the same worldwide market place.” Stuart, Tristram

We can assist to reduce obesity and environmental costs by addressing the excess of food in the United States. Here are some ways you may help reduce food waste by getting involved.

  • Determine the cause of your food waste: Do you have an excessive amount of food on hand that goes bad? Should you just purchase less items? If you don’t use it, that massive “bulk pack” may not be such a good deal.
  • Examine repurposing possibilities: Is it possible to cook the wilted fruits and vegetables? (Blackened bananas, for example, are ideal for banana muffins.) Is it possible to create a stew using leftover stir fry? Is it OK to feed food leftovers to animals? Is it possible to give leftovers to food banks or homeless people?
  • Consider composting: Research ecologically friendly food disposal methods.
  • Make a grocery list: Find out exactly what you have at home. Make use of any leftovers. Buy a little loaf of bread or a large loaf and freeze what you don’t need right away. Eat the crust; it makes up 10% of the bread. If you don’t like crusts on your bread, don’t eat it. Vegetables should only be peeled if absolutely necessary.
  • Use caution when it comes to “best by” and “use by” dates: Use your best judgment. Dates marked “sell by” may be totally disregarded. If you’re going to consume meat, be sure it’s from a sustainable source. Make sure the temperature in your refrigerator is between 36 and 40 degrees Fahrenheit (2-4 C).
  • Parents: Teach your children to respect food and to complete their meals. Serve just what you intend to consume.

Bonus points

While it may seem that transporting “separate” food waste is inconvenient, consider the following scenarios.

  • The Portland International Airport discovered that having one ton of garbage carried away cost them $82. They only pay $48 per ton for food waste. In 2008, they established separate containers for food waste and saved $5,600 in transportation costs alone.
  • Garbage cans were removed from the University of Dayton’s dining halls. Simply eliminating food trays in college dining halls resulted in a 38 percent reduction in food waste, since individuals take less and consume what they take.

We lose the whole upstream environmental footprint needed to manufacture and transport a single ready-to-eat salad when we toss it away.

Officials in India complained that not only do Americans consume excessive amounts of food, but that if they dropped down to the weight of middle-class Indians, “many people in Sub-Saharan Africa would find food on their plate,” as one official put it.

Do you recall crop gleaning? Some individuals are returning to gleaning: the necessity to feed starving families has rekindled interest in the practice. Also see Not Far From the Tree, a Toronto-based group that harvests excess fruit from local trees directly in the heart of the city.

Currently, enough food is redistributed in the United States to feed 26 million people.

“Nowadays, there are a lot of programs on food television about chefs doing fancy things with beautiful meals. Chefs are said to accomplish just that. That isn’t all, however. There are a lot of things that aren’t very fancy… Some chefs throw away food. They toss it away because they don’t know how to prepare certain portions of it or because they forgot about it in the refrigerator. They are uninterested in the components or the procedure. Vegetables and animals, on the other hand, are born to be eaten. Their lives come to an end at that point. We have a duty to make full use of everything. This is something we must comprehend. In the kitchen, a chef must consider the cuisine very carefully.” –Kaiseki Sakura chef Daisuke Izutsu

Food waste is already a huge issue, but it’s about to get worse. Last year, the USDA predicted that food waste in the U.S. would hit an all-time high of 33.9 million tons. But it’s far worse than that. The U.S. Department of Agriculture (USDA) announced this week that they now expect to hit 35.6 million tons of food waste. That’s 6 million tons more than the USDA expecte. Read more about food waste statistics 2020 and let us know what you think.
