Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring ...
Fecal sludge management ( FSM) (or faecal sludge management in British English) is the storage, collection, transport, treatment and safe end use or disposal of fecal sludge. [1] Together, the collection, transport, treatment and end use of fecal sludge constitute the "value chain" or "service chain" of fecal sludge management.
Garbage disposal unit. A garbage disposal unit (also known as a waste disposal unit, food waste disposer (FWD), in-sink macerator, garbage disposer, or garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The device shreds food waste into pieces small enough—generally ...
Food waste at the Songpa waste treatment facility is dumped into hoppers in July. Seoul, a city of 10 million people, produces 2,500 tons of food waste daily. (Jean Chung / For The Times)
Upflow anaerobic sludge blanket ( UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment . The UASB reactor is a methanogenic (methane-producing) digester that evolved from the anaerobic clarigester. A similar but variant technology to UASB is the expanded granular sludge ...
Food processing residuals are often referred to as FPRs. Treatment sludges, bones and feathers from slaughterhouses, and refuse from fruits and vegetables are among the common forms.
Sewage treatment is the treatment and disposal of human waste. Sewage is produced by all human communities. Treatment in urbanized areas is typically handled by centralized treatment systems. Alternative systems may use composting processes or processes that separate solid materials by settlement and then convert soluble contaminants into ...
Pollution. Food loss and waste is food that is not eaten. The causes of food waste or loss are numerous and occur throughout the food system, during production, processing, distribution, retail and food service sales, and consumption. Overall, about one-third of the world's food is thrown away.
