Here, we report a comparison of both bioconversions, made at a simulated industrial scale, considering techno-economic and environmental variables, and using renewable CO<sub>2</sub> and H<sub>2</sub> as feedstocks. 2,3-butanediol, a mid-range chain compound that can be produced via both routes, was selected for comparison. The comparison was set up in Chile due to expected low-cost renewable hydrogen and renewable CO<sub>2</sub> availability. The assessment showed that the minimum selling price of 2,3-butanediol in the anaerobic case was higher (3.91 (USD kg<sup>−1</sup>)) than in the aerobic case (3.36 (USD kg<sup>−1</sup>)), with hydrogen being the largest expense in both processes (50 % and 70 % of total expenses respectively). Further, owing to metabolic restrictions, the anaerobic process required almost five times more CO<sub>2</sub> than the aerobic process to produce the same amount of 2,3-butanediol. A Monte Carlo analysis showed that in most scenarios the aerobic process was more economically favorable. In environmental terms, the aerobic process had a smaller carbon footprint in all the evaluated scenarios.

To address this issue, various surface modification techniques have been developed, but these methods often alter the intrinsic properties of PDMS or introduce complexities in the manufacturing process. This study proposes elastomers based on ultraviolet (UV)-curable siloxane resins, which retain outstanding flexibility and transparency while significantly enhancing adhesion properties. UV-curable siloxanes were synthesized to prepare elastomers that were evaluated for their mechanical, thermal, and surface properties in comparison with PDMS. Results indicate that the prepared elastomers can be rapidly cured under UV exposure, achieving storage moduli 6 and 37 times higher than those of PDMS at 25 °C and 100 °C, respectively. Furthermore, thermal conductivity improved by 60 %, and the coefficient of thermal expansion was reduced by 26 %, demonstrating superior mechanical stability across diverse conditions.
