Commercial composting is the composting which carried out principally as a method of waste disposal which diverts this organic waste away from landfill. In the feedstock is green waste, or another “MSW residual waste” free organic material these facilities can produce a high quality compost used for garden and horticultural applications.
In the developed nations commercial composting is a local authority subsidized service, as it at present costs more to make the compost than the revenue from selling it.

Commercial composting is done at high temperatures which will rapidly compost the fresh compostable materials at the same time it also kills off any pathogens and bacteria that may be found in soiled disposables.
Commercial composting is not without its challenges. One of the biggest brakes in many areas to expanding the program is the question of where to find sites suitable for locating these plants.
Commercial composting is achieved by first sorting the waste, so materials that should not be composted are removed. For optimal decomposition, the starting contents should have a good carbon to nitrogen ratio, preferably 30 parts carbon to 1 part nitrogen.
For a company to send their waste for commercial composting is a way to show environmental responsibility.
Commercial composting is an industry that is growing and there a massive opportunities opening up into the future for the compost produced, and as oil prices rise. The agriculture industry is far too reliant on chemical fertilizers that require a huge energy input to produce, but the commercial composters can help reset the balance.
Commercial composting is a highly effective waste treatment, diverting biodegradable waste away from landfill where it would generate methane, a greenhouse gas over 20 times more damaging than carbon dioxide. Composting is a natural, aerobic process, meaning it needs oxygen to make it work.
Waste generation continues to increase worldwide in tandem with growth in consumption, and economic globalization facilitates the global transfer of wastes.
Composted material can also be used as landfill cover, which is applied daily to the top of landfills to allow easier access for trucks and reduce odors or disease.
It may seem like a waste of the material, but landfill cover is a necessity, and the alternative is using material-like tire chips. Materials and goods that are compostable must biodegrade within a certain time frame and must not leave a toxic residue.
A log is biodegradable, but not compostable because it takes years to fully biodegrade.
