Abstract

In a process to determine the amount of energy liberated during the forced aerated composting of organic matter in an otherwise closed vessel, the novelty is that: (a) the quantity of water is measured, which is formed by micro biological action during the composting process; (b) that the water content and enthalpy in the incoming and outgoing air are measured or determined, to determine the quantity of water formed by micro biological action; (c) the loss in weight of the organic matter is measured or determined; (d) the energy inputs and outputs and/or the quantity of water produced is measured, and this information used for the regulation and control of the composting process; (e) the cooling power setting or blower power are regulated to produce a given quantity of condensate per minute, providing a composting rate of e.g. 20 %.
