"Four in one" model and the development of household biogas in northern China
By reviewing the development of household biogas in China, one of the key factors which impeded the use of biogas in northern China was noted - how a biogas digester lives through the winter. In order to solve this problem, a model named "Four in one" has been proposed by some researchers. In this paper, this model, including its structure, technical features, and benefit was introduced and ...

Exergy analysis of solar energy assisted biogas plants for Turkey
The energy quality of solar energy assisted biogas plants established in Izmir, Turkey was investigated in this study via exergy analysis. This study was assisted together with other energy and economy analysis of these plants. Firstly, the plant was operated at mesophilic temperature region and it was continuously fed with cattle manure. The biogas efficiency reached a value as high as 1.3 ...

Renewable energy technologies in Nepal
Nepal, one of the least-developed countries, has a per capita energy consumption of about 336 kilograms of oil equivalent (kgoe), which is much below the world average of 1,474 kgoe. Around 85.27% of the total energy consumption comes from traditional energy resources and only 0.48% from renewable sources. About 40% of the total population has access to electricity. This 40% uses 33% from the ...

Research and development on biomass energy in China
Like developed countries, China is facing two serious constraints energy shortage and environmental pollution, which hinder the development of the national economy and improvements in living conditions. On the other hand, China has a huge amount of biomass resource. It is estimated that the total amount of biomass resource is up to 5.2x108 tons of oil equivalent (TOE) in which crop residue ...

Development of household biogas digesters and its economic analysis in China
During the development of biogas digesters, a problem, which is how to appraise the economic benefits, always exists. This paper mainly discusses the necessity of cost-benefit analysis on biogas digesters, clearly defines some vague concepts during the analysis, tells how to quantitatively analyse the environmental benefits, and affirms the role of the government and the rural families.Keywords: ...

Capturing biogas energy to increase your business profits while safeguarding the environment
Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

Precise biogas flow measurement: Overcoming the challenges of changing gas composition
INTRODUCTION As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is ...

Biogas recovery from a temperate climate covered anaerobic pond
New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...

Effect of thermal and alkaline pretreatment of giant miscanthus and Chinese fountaingrass on biogas production
Giant miscanthus (Miscanthus×giganteus) and Chinese fountaingrass (Pennisetum alopecuroides (L.) Spreng), cultivated for landscaping and soil conservation, are potential energy crops. The study investigated the effect of combined thermal and alkaline pretreatments on biogas production of these energy crops. The pretreatment included two types of alkali (6% CaO and 6% NaOH) at 22, 70 and 100 ...

Background of biogas technology and its recent developments in Iran
Biogas activities have been initialised since the mid 1970s in Iran. Only a few of about 70 rural projects are still active. Other activities include four municipal landfill gas extraction projects through which, two projects are being ready for power generation and some anaerobic treatment plants in industrial food processing factories. A modern research plant for practical investigation on ...

The Future of Biogas: Why Biogas Analyzers are Key to Advancements in Renewable Energy
As the world continues to shift towards sustainable energy sources, biogas is emerging as a valuable and versatile renewable energy option. Biogas is produced through the decomposition of organic matter, such as agricultural waste and sewage, and can be used to generate electricity, heat, and fuel. However, to get the most out of this resource, it is crucial to understand and monitor the quality ...

Energy from biogas
From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...
