Composting is the circular economy in action. Organic materials are recovered at source from parks and gardens. Without this segregation, these organic materials may go to landfill where they would produce greenhouse gases (GHGs) such as methane. As a GHG, methane is 28 times more potent than carbon dioxide. Enrich compost is a sustainable soil improver, it offsets the use of finite artificial fertilisers and peat. So, the act of composting is, in itself, reducing the release of GHGs.
During the composting process bacteria and fungi in the compost pile transform the organic matter into complex stable organic matter, often referred to as humus. Biologically stable compost contains approximately 200kg of stable organic matter per tonne. Carbon makes up 58% of this organic matter. Therefore, every tonne of Enrich compost used in your project sequesters up to 400 kg (0.4 tonnes) of carbon dioxide (CO2) equivalents. The average carbon footprint of an Irish person is 13t of CO2 per year.
