“…The results of this task could be used, together with the regional development plans envisaged by the local authorities, to produce a successful regional strategy for implementing the bioeconomy [54][55][56][57][58]. The next task would be a thorough evaluation of the potential impacts arising from the integration of the industrial and manufacturing sectors [12,43,59]. This will be key to determining the effectiveness of the proposed measures and actions, as outlined in the bioeconomy strategy.…”

Over the last decade, the bioeconomy has become increasingly important and visible in international policy agendas, with several strategies being recently developed. The implementation of bio-based technologies mostly takes place on a regional scale. Therefore, from a regional perspective, a key question revolves around what main challenges are associated with technological developments that could catalyze the implementation of sustainable bioeconomy regions. In this study, a cross-cutting analysis was carried out to determine these challenges. First, interviews were conducted with industry practitioners and scientists working in the bioeconomy field. These interviews were supplemented with a literature review to determine the status quo of bioeconomy strategies and their implementation, particularly on a regional level. A multidisciplinary workshop was then organized to identify the most relevant challenges in the short- and mid-term associated with establishing bioeconomy regions. The results show that there is a three-pronged challenge in innovative technological development from a regional perspective: (1) Resources: The establishment of sustainable regional feedstock strategies and supplies for supporting the bio-industrial sector; (2) collaborators: The establishment of a regional “critical mass” by fostering supply chain clusters and networks; and (3) neighbors: Understanding the local dynamics of societal trends and preferences and social acceptance of bio-technologies and their representative bio-based products.

“…Life cycle assessment was conducted according to the ISO 14040:2006 and ISO 14044:2006 standards, which define the basic structure and methodological procedures. 23 As LCA methodology is comprehensively described in the literature and widely applied to different products and processes, [24][25][26][27][28][29][30][31][32][33][34][35] no detailed description of LCA methodology is given here. The following sections describe the goal and scope definition, life cycle inventory compilation, and life cycle impact assessment (LCIA) of the bio-based IBN production system under study.…”

Isobutene (IBN, C4H8) is widely used in industry. Currently, IBN production relies on petrochemical processes. The current work assesses the comparative environmental sustainability of bio‐based IBN production routes based on first‐ and second‐generation sugar compared with fossil IBN by applying the ISO 14044‐based Life Cycle Assessment methodology. In total nine scenarios are examined. Scenarios 1–6 used first‐generation sugar for IBN fermentation and scenarios 7–9 use cereal straw‐based second‐generation sugar. The scenarios also differ in their process energy source. The savings in Global Warming Potential for first‐generation IBN are up to 68% (scenario 1); for second‐generation IBN, the savings reach 105% if an avoided burden approach for utilizing lignin as an energy source is applied (scenario 8). It is found that applying renewable process energy is a prerequisite to maximizing greenhouse gas savings. Special attention has to be drawn to the eutrophication potential, were none of the scenarios show savings. This is driven by sugar crop cultivation owing to fertilizer usage, thermal energy from solid biomass or natural gas due to NOx emissions and nutrient use for fermentation (e.g. ammonia). Scenarios 4, 7 and 8 show savings in the acidification potential compared with fossil IBN. A driver of acidification is biomass‐based process energy generation, mainly due to SO2 and NOx emissions from biomass combustion. In contrast, all scenarios show a better environmental performance concerning the freshwater aquatic ecotoxicity potential, the abiotic depletion and the photochemical ozone creation potential. Process development should focus on conversion efficiencies and a fully renewable process energy supply. © 2022 The Authors.

“…This approach has been previously tested for sea aster and sea fennel, focusing on the distribution of primary metabolites [31]. Green biorefinery is commonly used for grasses and forages, where the juice is often used to produce protein and organic acids, and the solid fraction is fed to animals or used for bulk materials and biogas [47][48][49]. As the high salt content of halophytes may limit their direct use as fodder [25,50], bioactive botanical extracts rich in phytochemicals could provide another value-added stream for halophyte-based biorefinery.…”

Harnessing the Value of Tripolium pannonicum and Crithmum maritimum Halophyte Biomass through Integrated Green Biorefinery

Bioactive extracts are often the target fractions in bioprospecting, and halophyte plants could provide a potential source of feedstock for high-value applications as a part of integrated biorefineries. Tripolium pannonicum (Jacq.) Dobrocz. (sea aster) and Crithmum maritimum L. (sea fennel) are edible plants suggested for biosaline halophyte-based agriculture. After food production and harvesting of fresh leaves for food, the inedible plant fractions could be utilized to produce extracts rich in bioactive phytochemicals to maximize feedstock application and increase the economic feasibility of biomass processing to bioenergy. This study analyzed fresh juice and extracts from screw-pressed sea aster and sea fennel for their different phenolic compounds and pigment concentrations. Antioxidant and enzyme inhibition activities were also tested in vitro. Extracts from sea aster and sea fennel had phenolic contents up to 45.2 mgGAE/gDM and 64.7 mgGAE/gDM, respectively, and exhibited > 70% antioxidant activity in several assays. Ethanol extracts also showed > 70% inhibition activity against acetylcholinesterase and > 50% inhibition of tyrosinase and α-glucosidase. Therefore, these species can be seen as potential feedstocks for further investigations.
