Think of it as dumping 80 quarter-pound hamburger patties in the garbage each month, or chucking two dozen boxes of breakfast cereal into the trash bin rather than putting them in your pantry. The report points out waste in all areas of the U. It cites several reasons, including that food has been so cheap and plentiful in the United States that Americans don't value it properly. Part of that problem comes from poor planning - such as impromptu decisions to eat out when there's still food in the fridge - and when we do cook at home, making enough to fill the plate rather than what we actually need to eat.
Singapore[ edit ] In Singapore, tonneslong tons;short tons of food was wasted in Consumer marketing and education[ edit ] One way of dealing with food waste is to reduce its creation. Consumers can reduce spoilage by planning their food shopping, avoiding potentially wasteful spontaneous purchases, and storing foods properly.
Starting inorganic waste from New York City restaurants will be banned from landfills. It is 25 times greater to impact climate change than CO2 in a year period. Most food waste is combined with general waste at the source.
Separate collections, also known as source-separated organicshave the advantage that food wastes can be disposed of in ways not applicable to other wastes. In the United States, companies find higher and better uses for large commercial generators of food and beverage waste. From the end of the 19th century through the middle of the 20th century, many municipalities collected food waste called "garbage" as opposed to "trash" separately.
This was typically disinfected by steaming and fed to pigs, either on private farms or in municipal piggeries. To keep collection costs down and raise the rate of food waste segregation, some local authorities, especially in Europe, have introduced "alternate weekly collections" of biodegradable waste including, e.
However, they result in a two-week wait before the waste will be collected. The criticism is that particularly during hot weather, food waste rots and stinks, and attracts vermin. Waste container design is therefore essential to making such operations feasible. Curbside collection of food waste is also done in the U.
Several states in the U. Collection of food scraps and yard waste combined is then recycled and composted for reuse. Animal feed[ edit ] Large quantities of fish, meat, dairy and grain are discarded at a global scale annually, when they can be used for things other than human consumption.
The feeding of food scraps to domesticated animals is, historically, the most common way of dealing with household food waste. 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. Bread and other cereal products discarded from the human food chain could be used to feed chickens.
Chickens have traditionally been given mixtures of waste grains and milling by-products in a mixture called chicken scratch. Composting is the aerobic process completed by microorganisms in which the bacteria break down the food waste into simpler organic materials that can then be used in soil.
The traditional decomposition process requires a long length of time and additional energy expended to turn the material frequently and maintain the aerobic process. Composting by thermophilic microbes can lead to nutrient loss and the compost product is heterogeneous, with the potential for higher levels of contaminants which can be harmful if used in agriculture.
Vermicomposting is the practise of feeding scraps to worms who produce fertilized soil as a byproduct. The product of vermicomposting is homogenous and generally contains lower levels of contaminants than traditional composting.
Some look to integrate vermicomposting and traditional composting in an effort to maximize efficiency while producing a high quality organic product that can be used in agriculture. In landfills, organic food waste decomposes anaerobically, producing methane gas that is emitted into the atmosphere.
When this biodegradable waste is composted, it decomposes aerobically and does not produce methane, but instead produces organic compost that can then be utilized in agriculture.
Transporting and dumping waste in landfills requires both money and room in the landfills that have very limited available space. Instead of food scraps and spoiled food taking up space in trashcans or stinking up the kitchen before the bag is full, it could be put outside and broken down by worms and added to garden beds.
Anaerobic digestion[ edit ] Anaerobic digestion produces both useful gaseous products and a solid fibrous "compostable" material. The United States Environmental Protection Agency states that the use of anaerobic composting allows for large amounts of food waste to avoid the landfills.
Instead of producing these greenhouse gasses into the environment from being in a landfill, the gasses can alternatively be harnessed in these facilities for reuse. These interactions require proper maintenance and personal protective equipment is utilized. This often foul-smelling waste contains both organic and inorganic waste chemical cleanersetc.
It is referred to as fats, oils, and grease FOG waste or more commonly "brown grease" versus "yellow grease", which is fryer oil that is easily collected and processed into biodiesel and is an overwhelming problem, especially in the USA, for the aging sewer systems.Why is Sustainable Management of Food Important?
Wasted food is a growing problem in our modern society and an untapped opportunity. In alone, more than 39 million tons of food waste was generated, with only percent diverted from landfills and incinerators for composting.
If food waste was a country, it would be the third biggest emitter of greenhouse gases after USA and China.  Eliminating global food waste would save million tonnes of C0 2 a year, the equivalent of taking one in four cars off the road.
The amount of food waste produced by wealthy countries could feed those in the poorest nations. The food production of sub-Saharan Africa nearly matches the amount of food wasted by the richest countries. Feb 26, · The report estimates that a third of all the food produced in the world is never consumed, and the total cost of that food waste could be as high as $ billion a year.
Estimates on the amount of food waste in America range from 30% – 40%. In this post you’ll learn about food waste in the United States, where and why it’s happening, and . POST-HARVEST FOOD LOSSES ESTIMATION- DEVELOPMENT OF CONSISTENT METHODOLOGY increase the amount of food available for human consumption and enhance global food security, Given the significant role food loss reductions could have toward sustainably.
