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...

In this paper the kinetics of biogas production was studied by performing a series of laboratory experiments using different lignocellulosic biomass mixed with fresh cattle dung at three different temperatures. Laboratory digesters each of 1000 ml capacity were used for the laboratory experiments in batch mode. Five different types of lignocellulosic biomasses such as bamboo dust, saw dust, sug...

Biogas production from sugarcane waste has large potential for energy generation, however, to enable the optimization of the anaerobic digestion (AD) process each substrate characteristic should be carefully evaluated. In this study, the kinetic challenges for biogas production from different types of sugarcane waste were assessed. Samples of vinasse, filter cake, bagasse, and straw were analyz...

*Correspondence: Junye Wang, Faculty of Science and Technology, Athabasca University, 1 University Drive, Athabasca, AB T9S 3A3, Canada e-mail: [email protected] Long-term economic and environmental concerns have resulted in a great amount of research on renewable sources of biomass and bioenergy to replace fossil fuels in the past decades. Decentralized biogas technology is one of the most ...

To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas. In this study, three lignocellulosic raw materials were studied, i.e. (1) winter rye straw (Secale cereale L), (2) oilseed rape straw (Brassica napus L.) and (3) faba bean straw (Viciafaba L.). Their composition with regard to cellulose, hemicellulose, lignin, ...

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...

The production of biogas has many advantages against other biomass based processes for production of energy or fuel. Biogas can be produced from any type of biomass whether it is a pure substrate or if it is a mix of materials like source-sorted municipal organic solid waste. The biogas process can handle substrate with different water content, from wet materials like Sewage sludge to dry mater...

The anaerobic digestion of organic waste for biogas production can be affected by some variables such as temperature; concentration of the biogas feed solution, bacteria populations, and pressure. This study investigated the effects of thermal pretreatment at 50, 75, and 100 ºC on the biogas produced by simultaneous anaerobic digestion of cow manure, mushroom waste, and wheat straw at thermophi...

Agriculture is a significant emitter of GHGs. Especially ruminant production systems that contribute substantially to global warming due to the enteric fermentation. Ruminant production systems are often integrated in mixed farm systems, including arable production, grassland systems and possibly energy production, which may provide opportunities for mitigation of GHGs when considered as a whol...

Poultry farms for meat or egg production is considered to be a huge business. However, waste including manure can give biogas that can produce electricity. In Pakistan load shedding problem remains throughout the year, therefore biomass being the cheap and efficient fuel for power generation can overcome this problem. This research has been conducted in Abbottabad district of Khyber Pakhtunkhwa...
