| الوصف: | Anaerobic digestion (AD) is a feasible strategy for biofuel production from biomasses (Ye et al., 2024). However, the presence of poorly biodegradable or inhibiting compounds in the feedstock might reduce AD process speed and methane yield. Indeed, several studies are focusing on possible strategies for increasing anaerobic digestability of specific biomasses. The current study focuses on improving anaerobic digestibility of a peculiar marine bio-waste represented by a mixture of P. oceanica litter and fish waste. P. oceanica is the most abundant seagrass of the Mediterranean Sea. During Autumn, leaves detach from the rhizome and accumulate in large amounts on the coasts, releasing unpleasant odours. Consequently, P. oceanica litter is usually removed and landfilled (Parente et al., 2013). With regard to fish, its production is globally close to 180 million tons and generates up to 60-70% of living fish weight in terms of wastes (Rathod et al., 2020). The coupling of P. oceanica and fish waste allows improving the features of this biomass as substrate for AD by balancing the C:N:P ratios, since P. oceanica is lacking in N and P, which are abundant in fish. Furthermore, these biomasses are characterised by high salinity, which suggest they should be both treated by an anaerobic biomass adapted to this condition. However, the high lignin and cellulose content of P. oceanica and the high heterogeneity of fish residues might affect the AD and slow down the process. Several tests were conducted in order to compare the biochemical methane potential (BMP) of this marine-waste in presence or absence of a thermochemical pre-treatment (132 °C for 30 min in autoclave in presence of 0.4% w/w of HCl), with different proportions between P. oceanica and fish residues, and different food/microorganisms ratios (F/M). The thermochemical pre-treatment conditions were selected according to a previous experience by the authors with P. oceanica (De Sanctis and Di Iaconi, 2019). Taking into account the presence of lignin and cellulose ... |
