The effect of adding vegetable waste as a co-substrate in the anaerobic digestion of swine manure was investigated. The study was carried out at laboratory scale using semi-continuous stirred tank reactors working at 37°C. Organic loading rates (OLRs) of 0.4 and 0.6g VSL−1d−1 were...

This paper assesses the resource of biomethane produced from food waste at a state level in the EU. The resource is dependent on the quantity of food waste available for anaerobic digestion and the specific methane yield from food waste. The specific method of undertaking biomethane potential...

Biomethane is a gaseous energy vector with a distribution system (the natural gas grid) in place. Biomethane may be produced through thermal gasification of Willow and may be used as a source of renewable heat. Two scales were assessed: a 50MWth facility based on indigenous Willow and a 300MWth...

Grass biogas/biomethane has been put forward as a renewable energy solution and it has been shown to perform well in terms of energy balance, greenhouse gas emissions and policy constraints. Biofuel and energy crop solutions are country-specific and grass biomethane has strong potential in...

Biogas production is one of the number of tools that may be used to alleviate the problems of global warming, energy security and waste management. Biogas plants can be difficult to sustain from a financial perspective. The facilities must be financially optimized through use of substrates with...

There are numerous ways to assess and compare biofuels. Gross energy per hectare reflects the quantity of product produced per unit of land. Net energy per hectare reflects the parasitic demand associated with the product per hectare. Gross and net energy per hectare are far superior for grass...

This paper examines the variability in biomethane potential from the organic fraction of municipal solid waste depending on source of origin. Eight organic waste streams were examined for biochemical methane potential (BMP). Specific methane yields of between 274 and 368mL CH4 gVS−1 for...
