Waste(d) potential: a socio-technical analysis of biogas production and use in Sweden
2015
Olsson, Linda | Fallde, Magdalena
This paper takes a socio-technical perspective on Swedish biogas production and use, in order to identify characteristics which may improve and increase biogas production. Biogas could potentially reduce greenhouse gas (GHG) emissions from Swedish road transport by 25%, and to that end transport policy endorses the use of biogas as vehicle fuel. Currently, however, only a small fraction of the biogas production potential is utilised. By analysing how social and technological context has influenced production and use of biogas over the past 70 years, using concepts from the theory of Large Technical Systems (LTS), features of importance for increasing biogas production are identified. Biogas is shown to be a complex issue, with different functions within the energy, transport and waste management systems. As there is not one coherent biogas system but many individual systems, with different objectives, local and sectorial measures are required in order to increase biogas production. In particular, the importance of biogas production as waste management is identified. In order to utilise the biogas potential and reduce GHG emissions from road transport, policy-makers and researchers are advised to address the plurality in biogas systems.
