Biological waste treatment
Composting
Composting is the controlled aerobic decomposition of organic matter by the action of
micro organisms and small invertebrates. There are a number of composting techniques
being used today. These include: in vessel composting, windrow composting,
vermicomposting and static pile composting. The process is controlled by making the
environmental conditions optimum for the waste decomposers to thrive. The rate of
compost formation is controlled by the composition and constituents of the materials i.e.
their Carbon/Nitrogen (C/N) ratio, the temperature, the moisture content and the amount
of air.
