Abstract:
Olivemill wastewater (OMWW) is a characteristic byproduct of oliveoil production and a major environmental problem in the Mediterranean area due to the high chemical oxygen demand (COD, up to 220 g. L1) and the high content of polyphenols. OMWW is considered as one of the most polluting agroindustrial effluents and could not be effectively process by classical biological treatment because of its phytotoxicity and antimicrobial properties. In this present work, a combined process consisting on absorption/adsorption of OMWW on sawdust, agropellets production from the OMWW/sawdust blends and energetic valorization via combustion was studied. Gaseous emissions such as CO2, CO and volatile organic compounds (VOCs) were measured during the agropellets combustion at temperature range 500700°C in a fixedbed reactor. The preliminary results show that the combustion of the impregnated sawdust pellets can be a promising strategy to reduce the amount of OMWW in the environment. Hence, a complete survey is necessary to find the optimal conditions in order to obtain an environment friendly biofuel with low impacts on the environment.
