A majority of food waste food is avoidable, with the rest being divided almost equally into foods which are unavoidable [clarification needed] (e.g. tea bags) and those that are unavoidable due to preference [clarification needed] (e.g. bread crusts) or cooking type (e.g. potato skins).
Nutrient pollution caused by Surface runoff of soil and fertilizer during a rain storm Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters ), in which excess nutrients, usually nitrogen or phosphorus ...
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters ), in which excess nutrients, usually nitrogen or phosphorus , stimulate algal growth. [ 1 ]
The company has reduced food waste by over 30% per person as compared with its 2019 baseline, according to its 2022 sustainability report, and has set new goals of 40% by 2025 and 50% by 2030.
Livestock waste can also enter waterways and introduce excess nutrients. Nutrient pollution from animal manure is most intense from industrial animal agriculture operations, in which hundreds or thousands of animals are raised in one concentrated area. Stormwater drainage is another source of nutrient pollution.
[94]: 1059 The only federal legislation to address water pollution during this era was the Rivers and Harbors Act of 1899. [95] In the 1899 law, Congress prohibited the dumping of "refuse"—debris that interfered with navigation—but other forms of pollution (e.g. sewage, food waste, chemical waste, oil spills) were not addressed.

Transforming food waste to either food products, feed products, or converting it to or extracting food or feed ingredients is termed as food waste valorisation. Valorisation of food waste offers an economical and environmental opportunity, which can reduce the problems of its conventional disposal.
According to a 2005 report by the USDA, more than 335–million tons of "dry matter" waste (the waste after water is removed) is produced annually on farms in the United States. [62] Animal feeding operations produce about 100 times more manure than the amount of human sewage sludge processed in US municipal waste water plants each year ...
