Collected and dumped not eaten foods that means remains of a hot meal after the meal is over, and everyone has finished eating is called leftover food. West materials and food scraps also conceder as leftover food(Cho et al., 2004a). The ultimate fate of leftovers depends on where the meal was eaten, the preferences of the diner, and the prevailing social culture.

According to Price et al. (1985), estimated values of the total global food loss and waste to around one third of the edible parts of food produced for human consumption, amounting to about 1.3 billion tonnes (1.28×109 long tons; 1.43×109 short tons) per year .

The animals turn roughly two thirds of their ingested food into gas or fecal waste, while the last third is digested and repurposed as meat or dairy products. There are also different ways of growing produce and feeding livestock that could ultimately reduce waste(Galanakis, 2015).
Currently, magnitude amounts of waste materials generated from household and industries have become one of the main factors to cause environmental pollution. Especially, as for the leftover food, the portion of leftover food out of total wastes has been continuously increased. Increases in feed cost for animal production motivated to recycle leftover food into animal feed (Cho et al., 2004a). Recycling leftover foods into animal feed has become one of the most important.
One of the methods to recycle leftover foods was to produce soil fertilizer using a fermentation technology although it caused several problems due to its high saline concentration. Therefore, the best recycling method of food waste was to convert it into animal feed(Kim et al., 2011). Converting and recycling of leftover food into animal feed are very important because leftover food can contribute to not only decreasing import of feed ingredients but also decreasing environmental pollution (Yang et al., 2001).

  • Food Desert Essay

    1235 Words  | 3 Pages

    A major issue that is occurring in America is a phenomena known as “food deserts”, most are located in urban areas and it's difficult to buy affordable or good-quality fresh food. Whereas in the past, food deserts were thought to be solved with just placing a grocery store in the area, but with times it has become an issue that people are not picking the best nutritional option. This issue is not only making grocery store in food deserts are practically useless and not really eliminating the issue of food deserts because even when they are given a better nutritional option, and people are not taking it. In my perspective, it takes more than a grocery store to eliminate ‘food deserts’. It's more about demonstrating the good of picking the nutritional option and how it can help them and their families. For example, “Those who live in these areas are often subject to poor diets as a result and are at a greater risk of becoming obese or developing chronic diseases.”(Corapi, 2014).

    In elementary school, we are taught by our teachers that fruit peels can be composted to recycle nutrients back into the soil where they came from. Composting food scraps is not a new idea by any means, but what if it was to be expanded into something much bigger? Recently, a study outlining the environmental impact of recycling digested food waste in comparison to that of chemical fertilizer was published by the Swedish University of Agricultural Sciences. In the experiment, the scientists found that currently, the two were relatively equal in terms of general environmental impact, and that in order for the food waste fertilizer to prevail, further enhancements will have to be made to

    All of the livestock being raised throughout the world produce enormous amounts of manure and urine, which in turn pollute natural resources. Animal waste changes the pH of our water, contaminates our air; and the gases emitted are believed to be a major cause of global warming. To keep costs down, the modern animal farming practice is to raise livestock in feedlots and factory farms where thousands or tens of thousands of animals are crowded into small spaces. However, this makes the animal waste problem worse because of concentrated waste. Livestock in the U.S. produce 2.7 trillion pounds of manure each year. That’s about ten times more waste than was produced by all the American

    Roberts believes that “food is a solution, a cause for joy and positive energy” (Roberts, page 18). Most of the time, it is more costly to waste the food than to use the food as a tool, which can bring new opportunities. As the example he provides in the book, Will Allen, a gardener from the US, uses spent grain as an opportunity to make compost for sale and to heat his own greenhouses using the heat generated from the composting process (Roberts, page 21). This way, he has also helped find an effective way to dispose of used food rather than treating it as trash which is actually not cheap to manage. Hence, Roberts concludes that there are so many hidden resources in the world, which can be used to work with food to create opportunities and to benefit the society, economy and environment while saving money (Roberts, page

In many states across the U.S., there are urban cities that have little to no access to grocery stores or supermarkets, severely limiting their supply and likelihood of receiving fresh produce to give to their families.
