In this paper the potentiality of combined heat and power production by thermochemical conversion of meat and bone meal (MBM) was investigated in a scenario related to Italian technical, socio-economic and strategic situation. A model for the steam and air gasification of MBM was developed using commercial software. The model was validated through a comparison of the predicted results to literature data. Sensitivity analyses were carried out to identify process conditions that provide highest efficiency. Considering an input flow rate of MBM of 100 kg/h, optimal parameters of gasification have been identified with equivalence ratio and steam/biomass ratio equal to 0.2 and 0.4, respectively. The produced dry syngas is 165.41 Nm3/h, with a LHV of 5.72 MJ/Nmdry3. The syngas was fed in a micro gas turbine simulation routine. This was previously validated by available data about commercial micro gas turbine. Useful information about global efficiency was obtained together with an economic analysis that frames the matter, in order to evaluate the pay back period and the net present value.
