Usually manure is considered an output product in livestock systems, which leads to the idea that it is simply residual, but manure should be considered a valuable product because of its nutrient and biogas potential [27]. The controlled production of biogas from said manure can reduce greenhouse gas emissions.

In this study, a novel heat exchanger with an optimal twisted geometry was developed based on the numerical screening of the twisted tubes with equilateral polygons, and experiments were conducted to validate the numerical results. the biogas as thus may vary widely in each individual case. Three of the studies compiled related to treatment plants, two in Germany and one in France. One general conclusion that was drawn is that since the sources vary so widely, the results are not representative for a specific substrate.

Considering that biogas production from cattle manure was not profitable in our base scenario analysis , and swine manure has a higher biogas yield; we use swine manure data for our computational experiments. Results and discussion. We apply computational experiments based on what-if scenarios.

These case studies represent a range of models that include type of feedstock, off take of products and utilisation of energy for both heat and / or electricity. The lessons learnt from these five case studies include that the business case for a biogas facility is highly site specific.

2019-10-03 · The use of biogas In Sweden increased by 29 percent between 2017 and 2018. Although biogas production in Sweden was almost unchanged, the use of biogas increased sharply thanks to a doubling of imports according to a recently published Swedish Energy Agency report on biogas production and the use of waste residues. Considering that biogas production from cattle manure was not profitable in our base scenario analysis , and swine manure has a higher biogas yield; we use swine manure data for our computational experiments. Results and discussion. We apply computational experiments based on what-if scenarios. pumping manure/liquid waste long distance in pipes in the ground.

Type of the animal, feeding regime, body weight, total solids ratio (TS), volatile solids ratio (VTS), the availability ratio of waste and biogas yield have high impact on the waste potential from animals. Availability of waste must be taken into

- 1 m3 of biogas is equivalent to 20 MJ [1] or 5.56 kWh of thermal energy. In this regard, the aim of this work was to achieve the production of biogas using the dry anaerobic technology through livestock manure co-digestion with agricultural waste (AW) such as potato peels, lettuce leaves and peas peels. The manure and AW were mixed at a ratio of 2:1 for 15 min before being introduced into the batch anaerobic system. These case studies represent a range of models that include type of feedstock, off take of products and utilisation of energy for both heat and / or electricity.

Compared to the waste itself, e.g. cattle manure, biogas residue contains a higher extent of essential nutrients (N, P, K, Mg) and trace elements (Arthursson, 2009). The long term effects of biogas residue on farmlands have been studied without any implication of risks towards the eco system (Odlare 2011b). Thus farm-based biogas plants will represent a small drop compared to total energy demand in Sweden, but additional energy production from waste products such as manure is always of interest. While the concept of farm-based biogas plants is not new in Sweden achieving profitability is still difficult.
