Abstract [en]

The option of producing the chemical succinic acid from bio-based resources is well in line with current political and industrial ambitions for a bio-based economy. A little explored but intriguing biomass feedstock opportunity is food waste. Mixed food waste is especially appealing as it represents less resource competition than more homogenous food waste fractions. The feasibility of producing succinic acid from mixed food waste depends on both technical and societal system structures. Therefore, to assess the production prospect, it is important to investigate all relevant system components. This study explores from such multiple perspectives the feasibility of chemical production as a viable added pathway for mixed food waste, using microbial production of succinic acid from municipal solid waste in Sweden as an example. The perspectives explored are: 1) feedstock feasibility, 2) societal drivers and barriers for technology progress, and 3) resource availability. Findings show that even though, from a technical feasibility and resource availability perspective, production seems possible, it lacks institutional support and actor commitment and alignment for development in Sweden. Findings also show that a holistic and interdisciplinary systems perspective contributes valuable insight when assessing prospects for bio-based chemicals.
