The present work concerns the economic and fi nancial evaluation of a small biogas plant (power plant of 250 kWel), with reference to the case of a biogas plant fed with a bio-matrix classifi able as both a by-product and a product. The study was focused on the comparison of several incentive systems that have followed over time. According to the analysis carried out using some economic indicators, results revealed that the investment profi tability was descending passing from the old

Furthermore, it is possible to emphasize that the use of products, rather than by-products, penalizes investment by reducing the incentive rate, thus putting the investment in a high fi nancial risk. Thanks to the present study, it can be assumed that the small biogas production plants enable positive benefi ts in social, economic and environmental terms.
