Abstract:

Fruit and Vegetable Wastes (FVW) are produced in very large amounts in all the wholesale markets in the world and in many other agro­industrial activities. Their disposal presents a lot of problems due to their quick perishability. Anaerobic digestion (AD) is a suitable treatment for the energy recovery from these wastes. This process application requires a deep knowledge of the influence of the operating parameters and the chemical composition of the wastes on the process performance. The results of a FVW anaerobic digestion experiment, divided in four time phases and carried out on pilot­scale, were analyzed by means of the Principal Components Analysis (PCA) to highlight the interactions between the operating parameters, the substrate chemical composition, and their effect on the reactor behaviour and on the biogas yield. The use of the multivariate analysis allows to take specific information on a complex biological process like anaerobic digestion. The method in fact permits to identify specific relationships among the process parameters even when they are subjected to an wide range of variation.
