Creating value from bio-residuals : Biogas solutions for biobased industries in Scandinavia
- 2022
-
Doctoral thesis (other academic/artistic)abstract
- This thesis focuses on biogas solutions for biobased industries as substrate management or energy providers. It investigates how such solutions are set up, what factors are important for their development, the effects on society and biobased industries, and the possibility of having biogas solutions as part of a sustainability strategy for biobased industries. The thesis has its scientific foundation in industrial ecology, the resource-efficient bioeconomy, and biogas solutions. The thesis is a synthesis of six appended papers focusing on value-creation, development, strategies, and the performance of biogas solutions in biobased industries.The results show that biobased industries can gain competitiveness, improved sustainability performance, and reduced costs through biogas solutions. The development of biogas solutions for biobased industries is improved through collaboration between actors where win-win solutions are identified, and resources are recovered locally. Biogas solutions will have an important role in recovering nutrients and improving resource efficiency of biobased industrial systems. This research contributes with the knowledge to implement more biogas solutions for biobased industries in different parts of the world by pointing out, additional values provided, factors to consider for the development, and the biobased industries’ strategic interest in biogas solutions.

Journal article (peer-reviewed)abstract
- Because biogas systems may take many forms, utilizing different feedstock and finding different end uses for the biogas, it is becomes difficult to produce explanations, inferences, and conclusions about biogas systems in general, which is why concepts for specific types of biogas systems are needed. This paper introduces the concept of the Nordic biogas model, an urban waste-based biogas system where biogas is upgraded to biomethane and used as transport fuel and the digestate applied as biofertilizer on farmland. The Nordic biogas model has three functions, namely, renewable transport fuel production, waste management service, and biofertilizer production that all bring secondary and tertiary positive societal effects, such as reduced climate gas emissions and productivity benefits to industry. This has implications for environmental and sustainability assessment of the Nordic biogas model as the multi-functionality must be considered when choosing reference scenarios, system boundary, and indicators to use within assessments. Finally, the paper discusses policy recommendations for supporting the implementation of the Nordic biogas model. Such policy should respect the multi-functionality of the Nordic biogas model by creating coherent policy mixes that neither neglect nor over-compensate for the multi-functionality of the Nordic biogas model.
