Farm-scale Biogas Plants
In Germany there are about fifteen years of experience in the planning and construction of farm-scale biogas plants. In the meantime, approximately 1,600 biogas plants are in operation on farms. This is primarily due to investment funding and payment for each kWh delivered to the public energy grid. In general, three different kinds of digester types are in use for anaerobically treating manure...
متن کاملFinding disturbances in on-farm biogas production.
When implementing innovations, disturbances are very likely to take place. Disturbances are undesirable because they can lead to unwanted outcomes, such as economic losses and work overload to workers. However, they can be powerful opportunities for learning and re-designing innovations. Here, we will present activity theoretical tools for analyzing disturbances in a way that they could be used...
متن کاملFeasibility Study on the Production of Biogas in Dairy Farming
The purpose of this study was to evaluate feasibility study on the development of biogas in dairy farming. In short of the production process, the biogas was produced by utilizing waste from dairy farming industry (i.e. cow’s manure and cassava peel). The production of biogas was analyzed from engineering perspective with several economic evaluation parameters, including gross profit margin, in...
متن کاملSustainable production of dairy farm systems
Sustainability of dairy farm production systems can be measured by the intersection between profitability and environmental stewardship. It is clear that unprofitable farms are destined to go out of business. Similarly, although not as evident, farms that are not efficient in the use of input resources, having higher wastages, and consequently producing more emissions, are likely to be un-susta...
متن کاملBiogas production from crop residues on a farm-scale level in Sweden: scale, choice of substrate and utilisation rate most important parameters for financial feasibility.
Anaerobic digestion would enable the energy potential of agricultural crop residues such as ley crops and sugar beet tops to be harnessed in Sweden. In the present study, the financial prospects of single-stage fed-batch high-solids digestion on three different scales, 51, 67, and 201 kW, were calculated on the basis of experimental results and observations. In addition to scale, the effects of...
