A Novel Artificial Photosynthesis Technology: Successful Synthesis of Biodegradable Plastic Raw Materials from Low-Concentration CO2 Equivalent to Exhaust Gas by UWaste-derived

Key points of this study

  • Synthesis of Biodegradable Plastic Feedstock from Waste Acetone and Low-Concentration CO2 Equivalent to Exhaust Gas.
  • The yield from the coupling of acetone with carbon dioxide was approximately 70%.
  • A significant step toward innovative artificial photosynthesis technology utilizing waste resources.

Summary

 Professor Yutaka Amao and Yu Kita, a second-year Master's student in the Graduate School of Science at the Osaka Metropolitan University, have successfully converted approximately 70% of waste acetone into 3-hydroxybutyrate, a biodegradable plastic feedstock, through artificial photosynthesis.

 In this study, we utilized waste acetone and low-concentration carbon dioxide equivalent to exhaust gas. By irradiating the reaction mixture with visible light for one day, equivalent to sunlight, we achieved the successful conversion.
This research offers a promising innovative approach to reduce carbon dioxide emissions while simultaneously producing biodegradable plastics from waste resources.

 This research has been published online in Green Chemistry, a journal of the Royal Society of Chemistry, on March 1, 2023.

Recognizing the importance of utilizing carbon dioxide from industrial exhaust gases, such as those from thermal power plants, rather than pure carbon dioxide for practical applications of artificial photosynthesis, we have successfully demonstrated the production of biodegradable plastic feedstock from low-concentration carbon dioxide via artificial photosynthesis. As there are still few studies utilizing low-concentration carbon dioxide, we are delighted that this achievement marks a significant step forward in the practical application of artificial photosynthesis.
