en undersökning av större biobränsleanvändares syn på biobränslemarknaden i Västerbotten
The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio …
En backcastingstudie för ett fossilbränslefritt Stockholms län 2050
… energy fuels) is reduced. If Stockholm county may take an 10 % part of the bio energy that the whole of Sweden can produce in the future the fossil fuel free energy-futures presented in this study is secured. The energy-futures also shows that the energy use per capita may reach …
en studie om lantbrukarnas alternativkostnader vid odling av rörflen
… by 20 percent the year of 2020. To reach these goals, the use of energy from biomass in the European Union will have to increase by 117 percent. Forest is the primary producer of bio energy in Sweden. Farmland as a producer of bio-energy is a scantly used resource. 70 000 …
en ekonomisk studie
Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned …
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to …
jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion …
