The aim of this paper is to show municipal and organic waste as an alternative source of energy and the benefits which can bring their energy use. These benefits concern both environmental reasons, as well as freedom from conventional energy sources and increasing energy security. The article discusses the biogas technology and plasma technology as the most promising waste to energy technologies.

<p>Biogas production process is an alternative method to reduce dependency on non-renewable fossil-based energy consumption and also can reduce greenhouse gases production both domestically and industrially. The existing biogas technology is suitable to be adapted in small-micro-medium enterprises and domestics, specifically for those who raise cattle. The case study was performed by observation of biogas production with various wastes as feed, namely cow dung, quail manure, and wastewater of tofu production. The study conducted via direct interviews with stake holders and visitations to the instalations. Based on our observation, biogas production from cow dung exhibits the shortest retention time compared to the others, aside from the value of C/N ratio of the biogas feedstocks. The presence of biogas production installations are significantly reducing the energy supplies among the users. Beside as biogas product, the instalations also produce solid and liquid fertilizers as by-products and have relatively high economic value. Socio – engineering problems based on the application of biodigester are also studied.</p>

This article investigates how biogas technology can facilitate the deployment of municipal circular bio-economic solutions within the energy and agrarian sectors in Denmark. The emphasis is on the regional climate policy and the existing biogas technology concepts, within a decentralized energy market located in the Southern part of Zealand. The case analysis will identify how such technology can be utilized as a lever for future “extraction-activities,” as for example protein, wax, and furfural substrates. Within Falster &amp; Lolland Municipalities, it is identified that 800.000 tons of animal manure is readily available for biogas production, just as 880.000 tons and 220.000 tons of unused beet tops and residual cereal straw could be feed to biogas facilities as for example co-silage materials. With a potential gas yield of approximately 897.000 MWh, composed by the crop residues alone, the challenge is how to utilize such resources the most efficient when addressing future needs for bio-products and high value materials and energy. Through the lens of Circular Bio-Economy this article addresses three themes, by which biogas technology can become an “engine” for future bioenergy solutions, where cascading activities and use of side-streams are developed: 1) production of biogas by means of local agricultural residues (beet tops, residual straw, and animal manure), combined with 2) “extraction-activities” as furfural and wax from straw, as well as protein from beet tops. Besides this 3) opportunities for upgrading the biogas and distributing it on a natural gas network, hereby enlarging the supply market for energy services from the biogas plant and facilitating the development of a more “integrated energy system,” currently being promoted by the European Commission. This article concludes on a step-by-step approach to utilize biomass residues more efficiently in light of the CBE concept and cascading approach, and the available biomass resources within the specific case area addressed.

This study presents the potentiality of biogas plants and their role for the conservation of environment. It is basedon primary data collected from 84 household surveys, 6 key informant interviews and two focus group discussions. It was observed that more than 95% of the people residing in the VDCs were using firewood as a main source ofenergy. The total amount of firewood consumed was 510.570 ton/year which emits 775.052tCO2e/year. Due to the presence of agriculture based livestock holding population, there is a great potential of biogas technology. Thestudy showed that biogas technology could saved 34.40% of firewood which conserves 5.415 ha of forests area. There is a potentiality of 58 biogas plants of size 6 cu.m which will reduce 440.800 tCO2e/year.DOI: http://dx.doi.org/njst.v15i2.12114Nepal Journal of Science and Technology Vol. 15, No.2 (2014) 51-56

This survey research based study sought determinants of biogas technology adoption in rural areas of Pakistan. Stratified random sampling technique was employed to select respondents because the population was unknown and heterogeneous in nature. Total 240 respondents (150 biogas users and 120 potential users) were selected and face to face interviewed using a structured, validated and pre-tested questionnaire. Along with descriptive analysis of data logistics regression model was applied to investigate the determinants of biogas adoption. Findings affirmed significant role of socio-economic characteristics  of respondents in the adoption of biogas technology. Empirical findings reported a significant impact of education, the income of households and the number of animals on the adoption of biogas technology. This implies that unit increase in education, income and number of animals will escalate the adoption of biogas technology. Tackling energy crisis, economic benefits, and production of slurry for soil fertility, health gains and environment-friendly nature of biogas were perceived reasons of biogas adoption among the biogas users. Non-government organizations and neighbours were leading motivational factors behind adoption as revealed by users. However, role of electronic media, print media and government institutionsin promoting biogas was reported dismal. This study urge that biogas is valuable alternative source of energy to combat energy crisis. In this way, provision of subsidies, interest free loans and technical backstopping could invoke potential users to adopt biogas technology.

The increased availability of reliable and efficient energy services stimulates new development alternatives. This article discusses the potential for such integrated systems in the stationary and portable power market in response to the critical need for cleaner energy technology. Several issues relating to renewable energies, environment, and sustainable development are examined from both current and future perspectives throughout the theme. It is concluded that green energies like wind, solar, ground source heat pumps, and biomass must be promoted, implemented, and demonstrated from the economic and/or environmental point of view. Biogas from biomass appears to have potential as an alternative energy source, potentially rich in biomass resources. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biogas technology. Finally, this article gives an overview of the present and future use of biomass as an industrial feedstock to produce fuels, chemicals and other materials. However, to be truly competitive in an open market situation, higher-value products are required. Results suggest that biogas technology must be encouraged, promoted, invested, implemented, and demonstrated, especially in remote rural areas. Anticipated future energy use patterns and consequent environmental impacts (acid precipitation, ozone depletion, greenhouse effect, or global warming) are discussed in this article. An approach is needed to integrate renewable energies in a way to meet high building performance. However, their ability to match demand is determined by adoption of one of the following two approaches: the utilisation of a capture area greater than that occupied by the community to be supplied, or the reduction of the community’s energy demands to a level commensurate with the locally available renewable resources. Adopting green or sustainable approaches to how society is run is seen as an important strategy in finding a solution to the energy problem. The key factors to reducing and controlling CO2, which is the major contributor to global warming, are the use of alternative approaches to energy generation and the exploration of how these alternatives are used today and may be used in the future as green energy sources.
