The invention relates to a compost-production method. The invention consists of an aerobic microbiological process involving the decomposition of organic material comprising purines and manure in a intensive composting module (14) into, inter alia, CO 2 , water vapour and mineral salts. The inventive method comprises the following phases consisting in: mixing (11) the purines (1) in situ with one more of the following products, namely manure (2), porous and hygroscopic substances (3) and a sponging agent (4), in order to obtain a spongy air-permeable mixture (5); placing the mixture (5) thus obtained in a compositing pile (12) constructed inside an intensive compositing module (14); in the decomposition and hygienisation stage, compositing the mixture intensively in the composting module, with the production of a hygienised pre-compost (7) and a leachate (6); recirculating (15) all or part of the leachate (6) to the compositing module (14); emptying the compositing module at a maturation station (17); and maturing and controlling the hygienized pre-compost for a pre-determined period of time in order to obtain a mature compost (8) or end product.
