High rates of resource consumption and waste generation have put pressure on environmental systems one the solutions to this concerning behavior is a circular bioeconomy (CBE). However, for CBE succeed, new businesses business models are needed, which many drawbacks might be faced. Therefore, article aimed (i) identify drivers, opportunities, challenges, barriers in both from theoretical practical perspectives, (ii) present regional differences those aspects different continents. A mixed-method approach was adopted, comprising systematic literature review semi-structured interviews with 32 organizations 18 countries 4 continents (Africa, America, Australia, Europe). Eight twenty as well fifteen drivers eight opportunities were identified. The main barrier challenge pointed out by stakeholders lack financial resources/capital, price competitiveness traditional/linear product offers. most prominent driver opportunity establishment public policies/governmental support, recovery. Regional CBEs (by continent) also Advancing requires setting strategies overcome developing and/or making adequate technology available locally, enabling traditional (linear non-renewable-based) options. This study unveils series managerial implications. There risk rebound effects, such becoming mainstream feedstock bioproducts being introduced market low-price strategies, thus triggering increased consumption. Premium pricing need considered bio-based products (compared non-bio-based products). Moreover, technological development plays role driving innovation, pioneers lead policies. For succeed there needs further greater connection among actors value chain, converging resilient CBE.

Abstract Rechargeable batteries play an integral role toward carbon neutrality. Environmentally sustainable should consider the trade‐offs between material renewability, processability, thermo‐mechanical and electrochemical performance, as well transiency. To address this dilemma, we follow circular economy principles to fabricate fungal chitin nanofibril (ChNF) gel polymer electrolytes (GPEs) for zinc‐ion batteries. These biocolloids are physically entangled into hierarchical hydrogels with specific surface areas of 49.5 m 2 ·g −1 . Ionic conductivities 54.1 mS·cm a Zn 2+ transference number 0.468 reached, outperforming conventional non‐renewable/non‐biodegradable glass microfibre separator–liquid electrolyte pairs. Enabled by its mechanically elastic properties large water uptake, stable electrodeposition in symmetric Zn|Zn configuration lifespan above 600 h at 9.5 mA·cm −2 is obtained. At 100 mA·g , discharge capacity Zn/α‐MnO full cells increases 500 cycles when replacing microfiber separators ChNF GPEs, while rate performance remains comparable separators. make battery completely transient, metallic current collectors replaced biodegradable polyester/carbon black composites undergoing degradation 70 °C. This work demonstrates applicability bio‐based materials green electrochemically competitive potential applications portable electronics, or biomedicine.

In this study, an advanced decarbonization approach is presented for integrated biorefinery that co-produces bioethanol and succinic acid (SA) from bread waste (BW). The economic viability the environmental performance of proposed BW processing evaluated. Four distinctive scenarios were designed analysed, focusing on a plant capacity processes 100 metric tons (MT) daily. These encompass: (1) fermentation into bioethanol, paired with heat electricity co-generation stillage, (2) energy-optimized integration Scenario 1 using pinch technology, (3) co-production SA by exclusively utilizing fermentative CO2, (4) version 3 incorporates carbon capture (CC) flue gas, amplifying production. Scenarios 4 found to be economically more attractive better due SA. Particularly, emerged as superior, showcasing payback period 2.2 years, robust internal rate return (33% after tax), investment 32%, remarkable net present value 163 M$. Sensitivity analysis underscored decisive influence fixed capital product pricing outcomes. terms impact, outperformed other across all impact categories, where global warming potential, abiotic depletion (fossil fuels), human toxicity potential most influential categories (−0.344 kg CO2-eq, −16.2 MJ, −0.3 1,4-dichlorobenzene (DB)-eq, respectively). Evidently, CC unit gas in substantially enhances both returns sustainability biorefinery.
