Exhausted poultry beddings: from environmental issues to resources

Given the relevance in food production of poultry farms, it is required to pursue technical solutions to cope with the environmental issues due to the exhausted poultry beddings disposal, as received by the European Directive EEC/91/676, which limits beddings\u2019 traditional spreading on soils. Alternative disposal routes are thus needed. The most promising option is the energy conversion for heat and/or power production. Small and medium size plants are here presented, to be installed inside the farm premises. Furthermore, synergies with the farm towards BAT\u2019s improving are pursued. Eventually, an economic analysis of the various plant sizes is hereby presented, considering some economic indexes (NPV, PBA, IRR, PI) and provided with a sensitivity analysis. The memoir also reports a series of charts for the technical and economic evaluation of plant size depending on specific farming type and farm siz
