“…Biogenic carbon capture and utilization routes offer additional avenues to support the decarbonization of the economy, in addition to carbon capture and belowground sequestration. Utilizing biogenic or renewable carbon as the core structural molecule offers many sectors new avenues to achieve net-zero emission targets, especially so-called hard-todecarbonize industries like petrochemicals (Kätelhön et al, 2019;Fernández et al, 2020).…”

Circular Bioeconomy Concepts—A Perspective

Circular economy concepts—including a circular bioeconomy—aim to transition the current, essentially linear, economic system to a more sustainable one. However, organizations and researchers currently define the circular economy concept differently, resulting in inconsistencies and difficulty in effectively implementing the framework. In this paper, we provide our perspective on the conceptual definitions of the circular economy, bioeconomy, and circular bioeconomy, outlining potential overlaps and differences and proposing a harmonized interpretation that stresses the importance of the carbon cycle. We conclude that the key goal of a circular economy is to slow, narrow, and close material resource loops, built on the foundation of renewable energy and non-toxic materials. Further, a sustainable bioeconomy goes beyond simply switching fossil resources with renewable, biological resources. It requires low-carbon energy inputs, sustainable supply chains, and promising disruptive conversion technologies for the sustainable transformation of renewable bioresources to high-value bio-based products, materials, and fuels. The bio-based circular carbon economy, in particular, stresses capturing atmospheric carbon via photosynthesis and exploiting this unique feature to the fullest extent possible. It sits at the intersection between the circular economy and the bioeconomy concept, resulting in a framework that focuses on closing the carbon cycle and stressing the opportunity to create an additional carbon sink capability in the technosphere by utilizing biogenic carbon for products and materials that are circulated in same or improved use cycles. Lastly, a sustainable circular bioeconomy transition will necessitate a set of consistent metrics that fit all products and industries.

“…MOF's high surface area and porous structure provide favourable catalytic efficiencies and high reaction yields, with some of these bifunctional materials allowing a direct transition from CCS to CCUS. 8,16 Understanding transport diffusion limitations in MOFs could positively inuence the catalyst effectiveness and facilitate the design of adsorption processes. 17 Nevertheless, this information requirement adds another level of complexity to the adsorbent screening process because the data available on mass-transfer resistance and diffusion limitations for MOFs is still scarce.…”

“…1,3 Fast and accurate characterisation techniques that provide crucial experimental data on solid sorbents, when linked together with molecular simulation and process-scale modelling are particularly desirable to move on to the next technology readiness level. 1,3,16 In this study we investigate the use of a gravimetric Dynamic Vapour Sorption (DVS) instrument as a rapid characterisation technique for novel adsorbent materials that permits several relevant industrial conditions to be investigated, allowing a range of equilibrium and kinetics descriptors of the adsorption process to be determined. In order to highlight the tunability and bifunctionality of MOFs we chose MIL-101(Cr)-4F(1%) as our material for this case study.…”

“…1 Carbon capture, usage and storage (CCUS) is one of the required pathways to minimize future emissions as well as capturing already emitted CO 2 . [2][3] Adsorption by solid sorbents and absorption by liquid amines are two promising routes to capture anthropogenic CO 2 . 4,5 Absorption by liquid amines is a well-known technology and it has been successfully tested at industrial scale.…”

“…41 The MMOs derived from the as-synthesized LDHs are studied for CO 2 capture at different temperatures under both, CO 2 rich (86 %) and lean (14 %) conditions. 3 and acetamide (acetamide/metal = 5) were taken in 100 mL water. The reaction mixture was stirred at room temperature for an hour to get a homogeneous mixture.…”
