“…Finally, focusing on specific regions allows for the adaptation to regional characteristics, such as local feedstock. Furthermore, the local knowledge of stakeholders, for example farmers, can provide significant advantages and add to the knowledgebase for the bioeconomy [30,37,58,59,63,80].…”

Abstract:The rise of the bioeconomy is usually associated with increased sustainability. However, various controversies suggest doubts about this assumed relationship. The objective of this paper is to identify different visions and the current understanding of the relationship between the bioeconomy and sustainability in the scientific literature by means of a systematic review. After a search in several databases, 87 scientific journal articles were selected for review. Results show that visions about the relationship between bioeconomy and sustainability differ substantially. Four different visions were identified, including: (1) the assumption that sustainability is an inherent characteristic of the bioeconomy; (2) the expectation of benefits under certain conditions; (3) tentative criticism under consideration of potential pitfalls; and (4) the assumption of a negative impact of the bioeconomy on sustainability. There is considerable attention for sustainability in the scientific bioeconomy debate, and the results show that the bioeconomy cannot be considered as self-evidently sustainable. In further research and policy development, good consideration should therefore be given to the question of how the bioeconomy could contribute to a more sustainable future. Furthermore, it is stressed that the bioeconomy should be approached in a more interdisciplinary or trans-disciplinary way. The consideration of sustainability may serve as a basis for such an approach.

“…Th e development of highly effi cient and cost-eff ective biorefi neries is a prerequisite for such a bio-based economy. 1,2 Th e cost of producing conventional petrochemicals is oft en lower compared to bio-based compounds, due to optimization of the production processes over more than half a century. Producers of bio-based products have so far primarily targeted high value or specialty chemical markets.…”

Bio-based succinic acid has the potential to become a platform chemical, i.e. a key building block for deriving both commodity and high-value chemicals, which makes it an attractive compound in a bio-based economy. A few companies and industrial consortia have begun to develop its industrial production on a large scale. A life cycle assessment of different bio-based succinic acid production processes, based on dextrose from corn, was performed to investigate their non-renewable energy use (NREU) and greenhouse gas (GHG) emissions, from cradle-to-factory gate in Europe. Three processes were studied, i.e. (i) low pH yeast fermentation with downstream processing (DSP) by direct crystallization, (ii) anaerobic fermentation to succinate salt at neutral pH (pH7) and subsequent DSP by electrodialysis, and (iii) a similar process producing ammonium sulfate as co-product in DSP. These processes are compared to the production of petrochemical maleic anhydride, succinic acid, and adipic acid. Low pH yeast fermentation to succinic acid with direct crystallization was found to have signifi cantly lower GHG emissions and NREU, compared to other fermentation routes and three petrochemical routes. However, the disparity in GHG emissions between this process and the electrodialysis process becomes less prominent if one considers a cleaner electricity mix than the current European production mix. Moreover, this study highlights that the allocation approach in corn wet milling and the succinic acid plant location strongly infl uence the results. Overall, the results suggest that low pH yeast fermentation with direct crystallization is the most benefi cial process to bio-based succinic acid from an environmental perspective.

Abstract-the disposal of synthetic fiber is very difficult to be degraded and cause problems in the environment. The renewable materials have potency as an alternative material for replacing the synthetic material in the composite product. This study was to determine the critical fiber length of mendong fiber embedded in the epoxy composite. The methods were the extraction of mendong fiber from straw, pull out test methods, and morphology analysis of pull out a test using scanning electron microscope. Results show that mendong fiber had a shear strength of 11 MPa and indicated a critical fiber length of 630 µm. The low critical fiber length of mendong embedded in epoxy matrix indicate good adhesion properties of mendong in an epoxy matrix. It recommends that mendong fibers can apply as reinforcement in the epoxy composite in the form of short fiber.
