Composting is perhaps one of the oldest methods of natural recycling put into practice by man.
Salvaging organic waste
and turning it into organic fertiliser
is an effective way to significantly contribute to the sustainable use of agricultural and environmental resources.
Compost - the end product of the composting process - is used as fertiliser on the land and, in addition to maintaining the fertility of the soil, it allows for a reduction in the use of non-renewable resources used to produce chemical fertilisers, thus reducing the amount of organic waste in disposal operations.
Organic matter also contains a high level of carbon which is maintained when it is made into compost.
The slogan of F.lli Boscaro Divisione Ambiente - Biorso emphasises and reminds us of the dual role that compost, derived from the treatment of plant waste, has in improving soil quality and in reducing the amount of organic waste thrown away so that organic substances are incorporated back into soil. This has therefore a dual effect in the reduction of CO2 emissions.
According to the Experimental Institute for Plant Nutrition in Italy, 0.15% of extra organic matter in the soil would be equivalent to feeding the soil with the entire amount of CO2 created by emissions in the whole of Italy in one year.
Even the use of organic soil amendments such as compost, instead of using chemical fertilisers, contributes to the reduction of greenhouse gases by avoiding using energy in the extraction and processing of virgin materials for distribution in the field.
Quality compost represents a source of carbon for the soil, which in the last thirty years, due to the progressive depletion of organic matter, has been reduced by about 50%. Restoring the organic fertility levels in soil would mean an overall balance of less carbon in the atmosphere and more carbon in the soil (compost vector of carbon).The soil can therefore act as a "sink" or "accumulator" of carbon, ensuring it is taken out of the atmosphere for a relatively long time.
