Abstract
The Biochemical Methane Potential (BMP) of several components of the Organic Fraction of the Municipal Solid Waste (OFMSW) were tested in order to assess the possibility to obtain a good estimate of the biogas production of a real scale anaerobic digestion plant. In particular, five different fractions and a mixed food waste sample were tested with batch anaerobic digesters at 37°C and both the BMP after 21 days (BMP21) and final BMP (BMPf) were measured. Regarding the mixed food waste substrate it was found an average BMP21 of about 405 NL/kgVS and a BMPf of 484 NL/kgVS with an average methane content of 57%. From the experimental results, some industrial potential biogas production were defined to compare them with data from real anaerobic digestion plants. In particular two different plants were considered: one located in a rural area that treats the source selected OFMSW from a public collection point, another located in a city area with a curbside collection system. Furthermore, studying the BMP of the pre-treatment reject of these plants, it was possible to study the pre-treatment efficiency and the difference performance of the two real plants.
