Artificial Photosynthesis Technology for Recycling Waste Resources!
Successful Synthesis of Biodegradable Plastic Raw Material from Low-Concentration CO2 Equivalent to Exhaust Gas Equivalent to Exhaust Gas by UWaste-derived
Key Points of This Research
- Synthesizing Biodegradable Plastic Raw Material from Waste Acetone and Low-Concentration CO2 Equivalent to Exhaust Gas!
- The Yield from Acetone Combined with Carbon Dioxide Is Approximately 70%!
- A Major Step Toward Innovative Artificial Photosynthesis Technology That Recycles Waste Resources.
Summary
Professor Yutaka Amao (Director and Professor, Research Center for Artificial Photosynthesis, Osaka Metropolitan University) and Yu Kita (Graduate Student, Graduate School of Science, Osaka City University) have successfully utilized artificial photosynthesis technology to convert approximately 70% of waste acetone into 3-hydroxybutyrate, a raw material for biodegradable plastics.
In this study, waste acetone and low-concentration carbon dioxide equivalent to exhaust gas were utilized. This research achievement was obtained by irradiating visible light equivalent to sunlight for one day.
These research results were published online on March 1, 2023, in Green Chemistry, an academic journal of the Royal Society of Chemistry.
For the practical application of artificial photosynthesis, we focused on the importance of utilizing carbon dioxide contained in exhaust gas from thermal power plants and the like, rather than pure carbon dioxide. We have finally succeeded in creating a biodegradable plastic raw material from low-concentration carbon dioxide using artificial photosynthesis! Since there are still few examples of research utilizing low-concentration carbon dioxide, I am delighted that we have taken a step forward toward the practical application of a new artificial photosynthesis technology.
