A mechanical biological treatment (MBT) system is a type of waste processing facility that combines a sorting facility with a form of biological treatment such as composting or anaerobic digestion. MBT plants are designed to process mixed household waste as well as commercial and industrial wastes .
Cultured dextrose is a food additive used to inhibit the growth of undesirable bacteria and mold in food. Often used in place of benzoates and sorbates, it is considered by some consumers to be a more "natural" ingredient, because it is prepared by the fermentation of milk or sugar powders by the probiotic bacteria Propionibacterium freudenreichii and Lactococcus lactis, both of which are ...
The organic waste like fallen leaves, kitchen waste, food waste etc. are fed into a crusher unit, where it is mixed with a small amount of water. The mixture is then fed into the bio-digester, where the archaea decomposes it to produce cooking gas. This gas is piped to kitchen stove.
A waste converter is a machine used for the treatment and recycling of solid and liquid refuse material. A converter is a self-contained system capable of performing the following functions: pasteurization of organic waste; sterilization of pathogenic or biohazard waste; grinding and pulverization of refuse into unrecognizable output; trash compaction; dehydration.
That may seem like a lot, but consider that between residential areas, commercial food service, and food retail, Americans generated 66.2 million tons of wasted food in the same year.
In the United States, 50% of homes had disposal units as of 2009, [12] compared with only 6% in the United Kingdom [13] and 3% in Canada. [14]In Britain, Worcestershire County Council and Herefordshire Council started to subsidize the purchase of garbage disposal units in 2005, in order to reduce the amount of waste going to landfill and the carbon footprint of garbage runs.

Pneumatic waste collection systems provide a number of environmental benefits. These systems can decrease emissions from transit of waste by up to 90%. [5] Systems in Europe provide separate outlets for food, recycling, and non-recycling, making waste separation and recycling more efficient.
The solvent waste stream from food processing may be used as reclaimed water, but there may be fewer options for disposal of a concentrated waste solute stream. Ships may use marine dumping and coastal desalination plants typically use marine outfalls .
