A cylindrical composter designed for composting dead animals has been commercialized for a certain time in Canada under the brand name BiovatorTM.. The main objective was to confirm the efficiency of the BiovatorTM. in Québec’s province pig farms. After a technical adaptation period, the appropriate stability of the process has been reached. Numerous samplings and physicochemical, microbiological and pathogenicity analyses showed that the compost, although not mature, is adequate for spreading in the field, under Québec’s governmental dispositions, having interesting soil fertilizer and amendment characteristics. Despite episodes of less intense composting due to massive inputs of swine carcasses (associated with a temperature drop inside the first section of the composter), the process has always been stabilized afterwards. Moreover, no leachate run-off was observed. The compost produced was stored on a concrete slab, in an area protected against bad weather. An economical study was also done, detailing the costs related to this technology and offering an interesting decision-making tool. Québec’s ministry of Agriculture, Fisheries and Food validated this new technology. This project showed the BiovatorTM to have many advantages: it requires little more labour than for the carcass collection service, performs efficiently in the diverse weather conditions of southern Québec, allows rapid removal of pig carcasses from the buildings and rapidly decomposes those carcasses (within two weeks). It also eliminates the cost of the dead stock collection service and the risk of contamination by the incoming collection trucks.
