In this paper, the possibility to obtain an alternative source of energy from methane fermentation, catalysed by biomass, has been discussed in detail. As a main substrate, distillation residue distillery industry was taken case mono-fermentation and its co-fermentation with sewage sludge. The results showed that higher biogas production can be obtained process. Fermentation lasted for 23 days,...

Biogas plants fuelled with renewable sources of energy are a sustainable means for power generation. In areas with high infestation levels with the European corn borer, Ostrinia nubilalis (Hbn.), it is likely that transgenic Bt-maize will be fed into agricultural biogas plants. The fate of the entomotoxic protein Cry1Ab from MON810 maize was therefore investigated in silage and biogas productio...

Biogas is considered a promising option for complementing the fluctuating energy supply from other renewable sources. Maize is currently the dominant biogas crop, but its environmental performance is questionable. Through its replacement with high-yielding and nutrient-efficient perennial C4 grasses, the environmental impact of biogas could be considerably improved. The objective of this paper ...

The increasing population and developing science and technology increased human comfort and needs which in turn increased need of burning fuel. Universal resource of this fuel in non-renewable therefore there is a constant search for renewable eco-friendly energy source. Biogas is one such energy which needs greater attention towards effective production of methane under anaerobic decomposition...

This study investigated the main factors influencing digester temperature and methods to reduce heat losses during the cold season in the subtropics. Four composite digesters (two insulated and two uninsulated) were buried underground to measure their internal temperature (°C) at a depth of 140 cm and 180 cm, biogas production and methane (CH4) concentration in biogas from August to February. I...

BACKGROUND Integration of first- and second-generation ethanol production can facilitate the introduction of second-generation lignocellulosic ethanol production. Consolidation of the second-generation with the first-generation process can potentially reduce the downstream processing cost for the second-generation process as well as providing the first-generation process with energy. This study...

Fruit and vegetable wastes are produced in large quantities in Iran, and constitute a source of nuisance in municipal landfills. The objective of this study was to optimize the applications of anaerobic digestion for the treatment of municipal organic wastes. We studied the effect of organic loading rates on anaerobic digestion of vegetable wastes. The complete-mix, pilot-scale digester with wo...

In present study, potentials of water hyacinth (Eichhornia crassipes) and water chestnut (Trapa bispinnosa) employed for phytoremediation of toxic metal rich brass and electroplating industry effluent, were examined in terms of biogas generation. Inability of the plants to grow in undiluted effluent directed to select 20%, 40% and 60% effluent concentrations (with deionized water) for phytoreme...
