Artificial photosynthesis technology that reuses waste resources!
Successful synthesis of biodegradable plastic raw materials from low-concentration CO2 equivalent to exhaust gas
Key points of this study
- Biodegradable plastic raw materials are synthesized from waste acetone and low-concentration CO2 equivalent to exhaust gas.
- The yield from acetone combined with carbon dioxide is about 70%!
- A major step towards innovative artificial photosynthesis technology that reuses waste resources.
Summary
Professor Yutaka Amao (Research Center for Artificial Photosynthesis, Osaka Metropolitan University) and Graduate student Yu Kita (2nd year doctoral student at the Graduate School of Science, Osaka City University) have succeeded in converting approximately 70% of waste acetone into 3-hydroxybutyric acid, a raw material for biodegradable plastics, using artificial photosynthesis technology.
In this study, waste acetone and low-concentration carbon dioxide equivalent to exhaust gas are used. This is the result of research obtained by irradiating with visible light equivalent to sunlight for one day.
The results of this research are expected to be an innovative way to not only reduce carbon dioxide but also create biodegradable plastics while reusing waste resources.
The results of this research were published online in "Green Chemistry" published by the Royal Society of Chemistry on March 1, 2023.
Focusing on the importance of using carbon dioxide contained in exhaust gas from thermal power plants, etc., rather than pure carbon dioxide, for the practical application of artificial photosynthesis, we have finally succeeded in creating a biodegradable plastic raw material by artificial photosynthesis from low-concentration carbon dioxide! There are still few examples of research using low-concentration carbon dioxide, and I am pleased that the practical application of a new artificial photosynthesis has taken a step forward.
