Composting is the aerobic (=oxygen using) decomposition and stabilization of solid organic materials by aerobic organisms. This process can be done under controlled conditions (=optimal conditions and environmentally safe) but also occurs in almost every environment where solid organic materials are supplied with oxygen, moist and the right temperature. The created compost should be a stable and hygienic substance witch is rich in humus en looks like soil.
Purpose
The purpose of the composting process is the removal of the biodegradable part of the organic materials, reducing volume, mass, particle size and humidity of the original waste. This process transforms the waste into a valuable soil conditioner that can be used in gardening and agricultural goals. The biodegradable part consist of saccharides (glucose, fructose, lactose, sucrose, starch), proteins and most fats. In the case that there is no oxygen available, the composting process is impossible and an anaerobic digestion takes place. This causes production of several gases (methane, small amounts of hydrogen sulfide and hydrogen gas...), resulting in bad smells.
