Recently, the increased consumption of poultry meat in the EU has been observed. Short cycle of poultry meat production allows adjusting the level of production to demand. With the increase in the meat production the amount of generated waste that has to be disposed because they pose a risk to the environment also increases. The work presents the possibility to produce a mixture of feathers, meat-bone meal and poultry litter that can be used for energy purposes (alternative fuel). Moreover, the composition of the ashes after combustion will be similar to phosphorus-potassium fertilizers offered for sale. The resulting granules are characterized by a calorific value in the range 13.1-13.3 kJg -1. The ash after its combustion contained 11.33-13.38% of phosphorous, 4.94-5.67% of potassium, 31.85-32.69% of calcium and 2.07-2.51% of magnesium. Moreover, the ash contained 0.45-0.46% of iron, 0.10-0.11% of manganese, 0.11-0.14 of zinc and 0.02% of copper. Mineral combusted residue of this type of granules has a low content of heavy metals and can be used as an additive to fertilizers and soil improvers, in order to enrich their composition in valuable macro-and micronutrients.

“…Basically, the solid wastes employed in the incinerator are rat labs, which can be used as fuel, because their heat value are comparable to the bovine meat (LHV = 16180 kJ/kg) [25]. For the current study, the fuel potential of the solid waste was neglected, mainly due to the composition variation.…”

In order to achieve satisfactory incineration, it is required that the combustion reaction occurs in high temperature, resulting in gaseous components with high exergetic potential that can be used for electromechanical power generation. This study makes an exergetic analysis, feasibility study and thermoeconomic evaluation for implanting a cogeneration system integrated to a solid waste incinerator from the Biotery located in the State University of Maringa. First and Second Laws of Thermodynamics are employed, by applying mass, energy, exergy and economic balances of the proposed system. Based on this evaluation it is possible to verify that the integration of a Rankine cycle using a micro-turbine of 123 kW with the incinerator is technically viable. The power generation costs was estimated ~11% lower than from the supplier and the operational costs of the incineration can either be decreased in ~ 22% to present investment return in up to 4.2 years. These cost reductions could make possible the continuous operation of the equipment, supplying conditions for the correct disposal of the solid waste generated by the university and Maringa city.

“…La solution retenue par le gouvernement français est l'incinération. Ce choix permet non seulement la destruction des farines mais également la production d'énergie en exploitant leur fort pouvoir calorifique (d'après le SIFCO, le pouvoir calorifique supérieur (PCS) des farines animales dégraissées varie entre 16 600 et 20 100 kJ/kg, valeurs en accord avec les travaux de McDonnell et al [1] et ceux de Conesa et al [2] ). La construction de quatre incinérateurs (initialement prévue à l'échéance de 2005 et actuellement compensée par des cimentiers et des centrales thermiques à l'étranger) permettrait d'accroître les capacités d'incinération de 220 000 tonnes par an et d'éliminer (en complément des cimenteries) la totalité de la production annuelle des farines.…”

Depuis l'épizootie d'encéphalopathie spongiforme bovine (ESB) en Europe dans les années 90, les farines animales de viande sont retirées de l'alimentation pour bétail et doivent être détruites ou transformées. Parmi les différentes solutions envisagées, l'incinération offre une perspective de valorisation thermique en exploitant le fort pouvoir calorifique supérieur des farines animales. Cependant, même si leur combustion est une source importante d'énergie, l'incinération produirait de grandes quantités de cendres (20 à 35 % du poids initial selon leur origine). A l'échelle de la France par exemple, la production annuelle de farines animales est d'environ 850 000 t. Dans le cadre d'une incinération systématique, la quantité de cendres produites (plus de 150 000 t/an) poserait la question de leur valorisation. Les cendres de combustion présentent des teneurs élevées en calcium (proche de 31 % en masse) et en phosphates (environ 56 % en masse). L'analyse par diffraction des rayons X montre la présence de phosphates de calcium, un mélange majoritairement constitué de Ca 10 (PO 4 ) 6 (OH) 2 et β-Ca 3 (PO 4 ) 2 . Parmi les différentes voies de valorisation envisagées, nos travaux démontrent que les cendres de farines animales présentent une forte capacité à immobiliser le plomb (environ 275 mg/g de cendres) en solution, permettant d'envisager un débouché dans l'environnement. Ces travaux démontrent également qu'elles peuvent être considérées comme source de phosphate pour l'industrie (production d'acide phosphorique, engrais …).Since the widespread occurrence of bovine spongiform encephalopathy (BSE) in the 1990's in Europe, Meat and bone meal (MBM) have been banned from animal feed and must be safely disposed of or transformed. Among the different processes studied, valorisation of MBM can be realised by a thermal treatment. Even if MBM combustion releases high energy, incineration produces huge amounts of ashes (20 to 35 % of the initial weight depending of their origin), the valorisation of which could become a major concern. In France for example, with nearly 850 000 t of MBM produced each year, ashes production would exceed 150 000 t/year. Combustion ashes present high level of Calcium (nearly 31 % weight) and phosphates (around 56 % weight). X ray diffraction analysis of ashes show the presence of calcium phosphates mainly as a mixture of Ca 10 (PO4) 6 (OH) 2 and b-Ca 3 (PO 4 ) 2 . In our search for new valorisation ways, we show that ashes display high lead uptake capacity in water (about 275 mg/g of ashes) and could then be used for pollution remediation. This work also underlines that MBM ashes can present a phosphate source for industries (phosphoric acid production, agricultural soil enrichment…).
