Abstract [en]

The transition toward a circular and biobased economy requires the biorefineries and bio-based industries to become more resource efficient with regards to their waste and by-product management. Organic by-products and waste streams can be an important source of value if used in feasible pathways that not only have a low environmental impact but also preserve or recover their energy, nutrients, and other potentially valuable components. Through development of a multi-criteria assessment framework and its application on a real case, this article provides methodological and practical insights on decision making for enhanced by-product management. Our framework includes 8 key areas and 18 well-defined indicators for assessing the environmental performance, feasibility, and long-term risk of each alternative. We studied six different management options for the stillage by-product of a Swedish wheat-based biorefinery and our results shows that the most suitable options for this biorefinery are to use the stillage either as animal fodder or as feedstock for local biogas production for vehicle fuel. This multi-criteria approach can be used by bio-based industrial actors to systematically investigate options for by-product management and valorisation for a circular and bio-based economy.

Abstract [en]

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.

Abstract [sv]

Denna avhandling kommer att fokusera på biogaslösningar inom biobaserade industrier och undersöka hur sådana lösningar är uppbyggda, vilka faktorer som är viktiga för deras utveckling, värden som skapas för samhälle och biobaserade industrier, samt möjligheten för biobaserade industrier att ha biogaslösningar som del av sin hållbarhetsstrategi. Avhandlingen har sin vetenskapliga grund i industriell ekologi, en resurseffektiv bioekonomi och biogaslösningar. Baserat på dessa forskningsområden har fokus legat på biogaslösningar inom biobaserade industrier och dess roll i den resurseffektiva bioekonomin. Avhandlingen är en syntes av sex bifogade artiklar som i sin tur fokuserar på värdeskapande, utvecklingsmöjligheter, strategier och prestanda för biogaslösningar inom biobaserad industri. Livscykelanalyser och multi-kriterieanalyser har utförts och kompletteras med fallstudier och intervjuer för att få den information som behövts för resultatet.

Resultaten visar att biobaserade industrier kan få ökad konkurrenskraft, förbättrad hållbarhetsprestanda och minskade kostnader genom biogaslösningar. Viktiga faktorer för utvecklingen av biogaslösningar som involverar biobaserade industrier förbättras genom samverkan mellan aktörer där fördelaktiga lösningar för alla parter identifieras, och resurser används lokalt. Biogaslösningar kommer vara viktiga för att återcirkulera näringsämnen och öka resurseffektiviteten i biobaserade industriella system. Denna forskning bidrar med kunskap för att sprida biogaslösningar inom biobaserade industrier runt om i världen, genom att peka på de värden som tillhandahålls, vilka faktorer som behöver beaktas för utvecklingen och genom att förstå de strategiska intressen som kommer från de biobaserade industrierna.
