Food waste refers to the edible food material that is discarded, whether at the household, industrial, or commercial level. This can include uneaten food, food that has gone past its expiration date, spoiled food, plate waste, and more. In some cases, food waste may also include food that has been produced but never harvested or food that is rejected because it does not meet certain quality standards.
There are many efforts underway to reduce food waste, including composting, donation programs, and waste reduction initiatives in households, businesses, and the food industry. By reducing food waste, we can conserve resources, reduce environmental impact, and help to ensure that food is available to those who need it.
There are several steps that we can take to reduce food waste, including:
The food process technologies can be broken down into biological digestion, non-biological volume/weight reduction, and thermal processing.
Food waste management is the activities and actions required to manage food waste.
This includes collecting, transporting, treating, and managing food waste and monitoring and regulating the food waste management process.
Collection of food waste: Collection systems that ensure clean food waste is brought to treatment.
Treatment of food waste: Food waste treatment alternatives, from windrow composting to anaerobic digestion.
Food waste disposal: Food waste can be composted to produce soil and fertilizer, fed to animals, or used to produce energy or fuel.
