The demand of energy has been increased over the years due to increasing world population and expansion of global industries especially for food and feed. Most of the energy is consumed in transportation, industries & factories, power generation, and community sectors. Moreover, in order to fulfill our demand we are mostly dependent on energy, taken from fossil oil, gas and coal. In developing ...

Fermentable components of municipal solid wastes (MSW) such as fruit and vegetable wastes (FVW), leaf litter, paddy straw, cane bagasse, cane trash and paper are generated in large quantities at various pockets of the city. These form potential feedstocks for decentralized biogas plants to be operated in the vicinity. We characterized the fermentation potential of six of the above MSW fractions...

To evaluate the feasibility of swine manure treatment by a proposed Dry Thermophilic Anaerobic Digestion (DT-AD) system, we evaluated the methane yield of swine manure treated using a DT-AD method with rice straw under different C/N ratios and solid retention time (SRT) and calculated the mass and energy balances when the DT-AD system is used for swine manure treatment from a model farm with 10...

BACKGROUND The diverse microbial communities in agricultural biogas fermenters are assumed to be well adapted for the anaerobic transformation of plant biomass to methane. Compared to natural systems, biogas reactors are limited in their hydrolytic potential. The reasons for this are not understood. RESULTS In this paper, we show that a typical industrial biogas reactor fed with maize silage,...

VIII Abstract Anaerobic digestion of energy crops for biogas production has attracted much interest in recent years. In Germany, the most common process is the continuous wet-fermentation of energy crops with cattle slurry or pig slurry (co-digestion). But also the digestion of energy crops as single substrate without slurry (mono-digestion) becomes more important. Because of the great diversit...

The increasing of crude oil prices recently in the world, the need for an alternative source of fuel in the Indonesia is urgently required. In addition, growing concern about climate change is driving the need for “low-carbon” fuels. One highly potential form of renewable and low-carbon fuel is biogas from anaerobic digestion of organic wastes. Anaerobic digestion is a naturally occurring proce...

abstract background: biogas is obtained by anaerobic decomposition of organic wastes buried materials used to produce electricity, heat and biofuels. biogas is at the second place for power generation after hydropower and in 2000 about 6% of the world power generation was allocated to biogas. biogas is composed of 40–45 vol% co2, 55–65 vol% ch4, and about 1% non-methanevocs, and non-methane vol...

Rice husks are a feedstock of biogenic silica because their high content. After extraction, solid residue comprising mostly carbohydrates is present. Solid valorization important for closed-loop systems using rice husk and has minimal negative environmental impacts. In this study, we used that was generated by extractionto anaerobic digestion producing biomethane. The characterized in terms tot...

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...

The presented work studies the possibilities of using maize silage for biogas production in laboratory as well as in full-scale conditions. From the results of long-term operation of a mixed laboratory anaerobic reactor, it follows that processing of maize silage as a single substrate is an unstable process due to the low alkalinity of silage that has to be compensated by pH adjustment. Specifi...
