Biomethane production from grass silage: laboratory assessment to maximise yields
… such systems may not be ideally suited to the digestion of grass. Ireland has ca. 3.85 million ha of grassland. Annual excess grass, surplus to livestock requirements, could potentially fuel an anaerobic digestion industry. Biomethane associated with biomass from 1.1 % of grassland in Ireland, …

Two-Phase Anaerobic Digestion to Reduce the NOx Emission Potential of Biogas
<p>Anaerobic digestion can be used to decrease the mass of organic wastes to be disposed of while producing useful biogas (CH<sub>4</sub> and CO<sub>2</sub>) for heat or power production, but in air basins with strict emissions limits, biogas combustion is difficult to implement due to the high …

Implementation of Acid/Gas Digestion Approach to Maximize Volatile Fatty Acids Production from Municipal Sludge and a Techno-economic Feasibility Study
<p>Acid digestion, which is the first step of two-phase acid/gas anaerobic digestion process, was studied to identify the optimum operating conditions that would maximize the production of volatile fatty acids (VFAs). Batch and semi-continuous acid digesters were operated using combined primary …
