D-Glucose was dissimilated aerobically by a strain of osmophilic yeast producing glycerol, D-arabitol, ethanol, carbon dioxide, and a small amount of succinic acid. Glucose-1-C14 gave glycerol labeled in the terminal carbons, D-arabitol labeled in carbon-1 and carbon-5, methyl labeled ethanol, and succinic acid with 30% of the labeling in the carboxyl carbons and 70% in the methylene carbons. Glucose-2-C14 gave glycerol labeled in carbon-2, D-arabitol labeled in carbon-1, carbon-2, and carbon-4, carbinol labeled ethanol, and succinic acid having 70% of the labeling in the carboxyl carbons and 30% in the methylene carbons. Labeled carbon dioxide was produced from both carbon-1 and carbon-2 labeled glucose but the specific activity of carbon dioxide from glucose-1-C14 was higher than that from glucose-2-C14. The distribution of radioactive carbon in the products is explained by assuming that glucose is dissimilated via a combination of the Embden–Meyerhof and the phosphogluconate oxidation pathways, with transketolase-catalyzed reactions playing an important part in D-arabitol formation.

Carbon dioxide is inexpensive and abundant, and its prevalence as waste makes it attractive as a sustainable chemical feedstock. Although there are examples of copolymerizations of CO2 with high-energy monomers, the direct copolymerization of CO2 with olefins has not been reported. Herein, an alternate route to tunable, recyclable polyesters derived from CO2 and butadiene via an intermediary lactone, 3-ethyl-6-vinyltetrahydro-2H-pyran-2-one, is described. Catalytic ring-opening polymerization of the lactone by 1,5,7-triazabicyclo[4.4.0]dec-5-ene yields polyesters with molar masses up to 13.6 kg/mol and pendent vinyl sidechains that can undergo post-polymerization functionalization. The polymer has a low ceiling temperature of 138 ºC, allowing for facile chemical recycling. These results mark the first example of a well-defined polyester derived solely from CO2 and olefins, expanding access to new feedstocks that were once considered unfeasible.

Recent developments in catalysts have enhanced the potential for the utilisation of carbon dioxide as a chemical feedstock. Using the appropriate energy efficient catalyst enables a range of chemical pathways leading to desirable products. In doing so, CO2 provides an economically and environmentally beneficial source of C1 feedstock, while improving the issues relating to security of supply that are associated with fossil-based feedstocks. However, the dependence on catalysts brings other supply chains into consideration, supply chains that may also have security of supply issues. The choice of chemical pathways for specific products will therefore entail an assessment not only of economic factors but also the security of supply issues for the catalysts. This is a multi-criteria decision making problem. In this paper, we present a modified 4A framework based on the framework suggested by the Asian Pacific Energy Research centre for macro-economic applications. The 4A methodology is named after the criteria used to compare alternatives: availability, acceptability, applicability and affordability. We have adapted this framework for the consideration of alternative chemical reaction processes using a micro-economic outlook. Data from a number of sources were collected and used to quantify each of the 4A criteria. A graphical representation of the assessments is used to support the decision maker in comparing alternatives. The framework not only allows for the comparison of processes but also highlights current limitations in the CCU processes. The framework presented can be used by a variety of stakeholders, including regulators, investors, and process industries, with the aim of identifying promising routes within a broader multi-criteria decision making process.
