In-vessel Composting

In-vessel composting is an industrial form of composting biodegradable waste that occurs in enclosed reactors. These generally consist of metal tanks, or concrete bunkers, in which air flow and temperature can be controlled, using the principles of a "bioreactor". The term "in-vessel composting" is used to refer to a composting system which encloses the compostable waste, therefore allowing for a higher degree of process control than is possible with windrow composting.

As the need for more sustainable alternatives to landfill continues to grow globally, in-vessel composting plays a vital part in meeting national waste objectives. Furthermore they are able to process a wide range of organic materials including:

• Kitchen kerbside domestic collected organics

• Catering waste, including meat and fish

• Local Authority CA site garden waste

• Commercial fruit & vegetables

• Liquid food waste

In-vessel composting is unlike "anaerobic digestion," which uses microorganisms to break down biodegradable materials in the absence of oxygen, whilst in-vessel composting uses air.

The air circulation is metered in via buried tubes that allow fresh air to be injected under pressure, with the exhaust being extracted through a biofilter. Temperature and moisture conditions are monitored using probes in the mass to allow maintenance of optimum aerobic decomposition conditions. Over a period of approximately one week, temperatures of 70c are achieved and sustained for one hour. This procedure is managed at all times to comply with ABPR (Animal By-Products Regulations) and ensures the destruction of weed-seeds and pathogens, and decomposition in a controlled, managed environment to ensure all EU composting standards are met.

This technique is generally used for municipal scale organic waste processing, including final treatment of sewage bio-solids, to a safe, stable state for reclamation as a soil amendment.
