Abstract:

The production of biogas from organic solid wastes represents a very promising challenge for the production of energy from waste biomass. Anaerobic fermentation of manure, sewage sludge, biodegradable wastes and municipal wastes represent a simple and effectiveness way to produce biogas, a mixture of methane and carbon dioxide. As co­substrate, husk, coming from olive oils mills, represents a source of pollution with strong effect on soil: its reuse permits the valorization of such residual by solving an environmental problems. Therefore, the use of husk, with its acidity and polyphenols compounds, should be well monitored, in order to avoid some interference with microbioactivity of methanigenes bacteria. In this paper the biogas production in a pilot­scale fermentor carried out with mixture of solid organic and husk has been optimized in order to find the optimal feed ratio. Different feed ratio have been tested ranging from 0 to 15% of of husk, the effect of wastewater (0­50% in the feed) has been analysed too. The amount of biogas and its composition have been related to the operating parameters like temperature, mixing rate and conditions, organic solids and vegetable residuals feed mass ratio. Experimental results obtained at both laboratory and pilot scale permitted to estimate the optimal feed composition in order to maximise the biogas production.
