Compost-making is an oxidisation biological process that makes it possible to recycle the organic part present in most of the waste produced by human activities, adopting the same mechanisms that in nature regulate the cycle of material. In time, the biodegradable organic matter is attacked by various types of micro-organisms, which produce a biologically stable material called compost, equivalent to the humus that can be found in the ground of forests. Drawing on its experience in the pure oxygen development of biological activity, SOL is able to offer innovative process solutions, thanks to which compost-making becomes a convenient choice for the treatment of organic waste. The objectives pursued by employing SOL 's technologies are the following:

• reduction of the production of unpleasant smell
• production of high-quality compost
• increase in productivity
