About 30 percent of the 430 billion lbs of food produced in the United States is wasted, an incredible statistic, especially given the lack of landfill space, not to mention the global menace of world hunger.

The shocking statistic gives a new meaning to the term ‘junk food,’ as Americans are sending 133 billion lbs (60 billion kg) of food to the garbage dump each year. To put it another way, 141 trillion calories annually – or 1,249 calories per capita daily – went uneaten in the United States, according to a report by the US Department of Agriculture.



The top three food groups in terms of the amount of total food loss cost are ranked as follows: meat, poultry, and fish (30 percent); vegetables (19 percent); and dairy products (17 percent). Retail food waste, for example, in grocery stores and restaurants, accounted for 10 percent (43 billion lbs), while consumer losses amounted to 21 percent (90 billion pounds) of the available food supply.



The issue of food loss is becoming a serious topic not just in the United States, but across the world as countries struggle with mounting levels of garbage, while food scarcity among an exploding world population demands a new way of thinking about eating habits.



In 2010, the average American spent $4,016 on food (both for at-home and away-from-home consumption) out of an average disposable income of $36,016, the report, titled ‘The Estimated Amount, Value and Calories of Postharvest Food Losses at the Retail and Consumer Levels in the United States’, noted.



Meanwhile, according to the Centers for Disease Control and Prevention, more than one-third of US adults (35.7 percent) are obese, which is perhaps the best argument that Americans can offset a large part of the food waste problem by simply eating less. The estimated annual medical cost of obesity in the US was $147 billion in 2008; the costs of providing medical assistance for individuals who are obese were $1,429 higher than those of normal weight, thereby placing an enormous strain on healthcare costs.

At the same time, the problem of global food scarcity is gaining the attention of world leaders.



“The United Nations predicts that the world population will reach 9.3 billion by 2050, and this will require a 70 percent increase in food production, net of crops used for biofuels. Currently…the number of food-insecure people reached 802 million in 2012,” the report stated.



The USDA warned that developed countries like the United States – where 49 million people lived in food-insecure households out of a total population of over 305 million - should not take their current level of food security for granted.



“Although most of this population growth will occur in developing countries, developed countries like the United States also face issues of hunger and food insecurity,” it said.



In an effort to attract attention to the problem of food waste, the USDA and the US Environmental Protection Agency (EPA) last year kicked off the US Food Waste Challenge. The United Nations’ Environment Program’s (UNEP) World Environment Day’s central theme was also food waste.



The report acknowledged that tackling the problem is no easy challenge given the many diverse places where food is distributed, consumed and disposed of.



There are an estimated 119 million households, over a half a million dining establishments, including fast-food outlets, and numerous other locations where people gather to eat, such as schools, institutions, and prisons across the United States, it said.

Eco-hazardous habits



A largely ignored problem associated with our intensely urbanized lifestyles is how to get rid of our food waste in a way that does not inflict long-term damage on the environment. Discarding uneaten food into plastic garbage bags and burying them in landfills only exacerbates the problem.



According to statistics by the US Environmental Protection Agency (EPA), food waste accounted for 34 million tons of some 250 million tons of municipal solid waste in the United States in 2010, with a price tag of about $1.3 billion.



After recycling a number of materials, like metals, plastic and paper, food waste came out on top in terms of what is overloading our garbage dumps, with 21 percent of the total, according to the EPA.



The most worrying problem with landfilling food waste is that it generates methane gas as it decomposes anaerobically. Methane is 21 times more powerful in accelerating global warming than carbon dioxide, according to the EPA as cited in the USDA report.



Landfills account for 34 percent of all human-related methane emissions in the United States

The report pointed to a growing human footprint on the planet as a good reason for nations to start addressing this issue.



The report offered some suggestions on addressing the issue, including expanding on community composting programs, of which there are around 3,510 such initiatives in the US that allow neighborhood residents to leave food scraps and yard trimmings at the curb for a special collection.



At the same time, companies will work to offset food waste if “it is economically justifiable, that is, if the benefits outweigh the costs.”



The report suggested the potential advantages of building “consumer goodwill” for business, using by way of example “a sandwich shop donates uneaten yet wholesome food to a community feeding organization at the end of each day.”
