Purpose: This study focuses on increasing production of biogas as an alternative energyfrom biodegradable wastes (BWs) using BSA coated iron oxides nanoparticles, in view ofsolving waste management at household level. Many attempts have been performed in orderto increase biogas production, including thermal pre-treatment of organic waste, but all ofthem present limited industrial applications. Iron has been shown to enhance anaerobicdigestion, but there are severe drawbacks for introducing the metal ion in an anaerobicclosed reactor.Design/methodology/approach: Process for the production of biogas from biodegradablematerial which comprises the steps of: (a) adding the biodegradable material to the Bioreactor,(b) inoculating the microorganisms in the digester,(c) synthesis iron oxides and BSApowder coated on the particles (d) adding a colloidal solution of surface-modified BSA-ironoxide nanoparticles to the reactor; (e) providing anaerobic conditions; (f) carrying out theanaerobic digestion; and (g) collecting the biogas, wherein the steps (a), (b) and (c) can becarried out in any order. It also comprises the use of BSA-iron oxide nanoparticles capableof supplying Fe ions to the media for biogas production in anaerobic conditions and in thepresence of Fe ions in the media.
