The Aerochamber Technology is a purpose designed Micro-Climate composting technology scientifically designed to biodegrade food and green putrescible waste into rich humus for organic food production sustainability, additionally abates Greenhouse Gas Emissions. This website describes the scientific and technical theory of the advantages of the Aerochamber technology, additionally demonstrates the Environmental and Economic benefits of the technology to abate greenhouse gases.
The Aerochamber Technology is a reference for Educating Organic Waste Recycling for Schools and for other Environmental teaching institutions.
Low Carbon/Nitrogen Ratio material (Putrescible Waste) is essential in the composting mix to supply a Nitrogen base for plant fertility and growth.
Putrescible Waste from the MSW stream is problematical and costly for Local Governments to administer globally, the Aerochamber Technology addresses these issues with large Environmental, Economic and Sustainable benefits for Local Governments and the general public.
• A Twelve Month Test Evaluation was carried out in Brisbane Australia in 2009 to evaluate the Biodegradation rate of two different size updated designed Aerochamber, using household putrescible waste From the Municipal Solid Waste Stream (MSW) stream .
• The 612lt Aerochamber Biodegraded 1876 kg of putrescible waste, and produced 519 kg of high quality fertility rich compost material (Humus).
• The 300lt Aerochamber Biodegraded 876 kg of putrescible waste, and produced 206 kg of high quality fertility rich compost material (Humus).
• Due to a smaller surface to volume ratio, the 612 lt Aerochamber was more efficient.
• Both Aerochamber prototypes biodegraded approximately seven times their volume capacity of putrescible waste in a twelve month period in Brisbane Australia.

Knowing what to put into the composter is most important for a successful outcome to produce high quality compost (humus) to grow strong and healthy produce.
A well designed composter needs an adequate supply of oxygen for aerobic microbial activity to biodegrade all organic Waste Aerobically, known as Aerobic Biodegradation for Aerobic Micro Flora and Micro Fauna to rapidly multiply to achieve carbon Abatement. Oxygen transport and Oxygen diffusion is when oxygen can freely travel throughout the composting pile and convert the oxygen to Carbon Dioxide, known as biogenic emissions (naturally occurring emissions). Factors that limit Oxygen transport is primarily the lack of oxygen supply throughout the composting pile, due to a poor compost bin design, and a high moisture content of the compost material.
All organic matter, including all food and green waste has a Carbon Nitrogen ratio C/N ratio, the ideal for composting is 30/1 C/N ratio. Too wide a C/N ratio slows down the composting process and too narrow a C/N ratio can lead to nitrogen loss
The ideal moisture content for composting is approximately 60%,
The Biodegradation rate is associated with the volume capacity of each composter.
The rate at which the compost material biodegrades is influenced by factors including, an adequate oxygen supply, a balanced C/N ratio and appropriate moisture content of approximately 60% The biodegradation rate will vary in each climate zone depending on temperature variations.
The Aerochamber technology has had a twelve month test evaluation in Brisbane Australia and biodegraded approximately seven times the volume capacity of each Aerochamber using putrescible waste material from the Municipal Solid Waste Stream, meaning (general household food and garden green waste)
Putrescible Waste is all organic food and garden green waste that contains a low Carbon/ Nitrogen Ratio, (has a lower carbon content to nitrogen content that would be normally recommended, the ideal for composting is 30/1 C/N ratio, putrescible waste can be as low 15/1 C/ N ratio, this waste stream requires an adequate supply of oxygen when composting to prevent putrification and to abate Greenhouse Gases.
As energy is liberated by biological oxidation of part of the Carbon, some of this energy is used in metabolism and the rest is given off as heat. Heat generated in a composter from biological oxidation will only occur if the composter is initially full of waste material, however when a composter has small increments of added waste no heat will be generated. It is always advisable to place the composter in the sunniest position to obtain maximum solar heat.
All organic waste has a Carbon Nitrogen ratio, the low C/N ratio materials include all kitchen food waste and green garden waste, including meat, grass clippings, fish waste etc. (putrescible waste) It is the low Carbon/Nitrogen ratio waste material (putrescible waste) that supplies the Nitrogen base for plant fertility and nutrients to grow strong and healthy produce. The Aerochamber composting design has an adequate supply of oxygen to prevent putrification from low C/N ratio material, and to achieve carbon abatement.Learn about Carbon abatement
