Composting
Importance of composting
In recent times agricultural comsumption has disrupted the carbon cycle by harvesting organic carbon (crops) from soils and disposing of carbon containing waste (food) to landfills and sewers. This results in landfill leachate, nutrient enrichment of waters, loss of soil quality and release of greenhouse gases. Controlled composting offers a sustainable process for beneficial reuse of waste (organic resources) which will prevent further environmental degradation, improve productive soils and maintain the carbon cycle.
- Composting is the process whereby unstable putrescible (smelly) organic waste is transformed into stable odour free compost.
- Compost is a granular, dark coloured soil-like material high in organic matter.
- Composting is a natural biological process which produces heat, water, carbon dioxide (no methane gas) and compost (approximately 50% of the input mass).
- Good compost from good organic feedstock is valuable.
- Composting can generate tradable carbon credits.
