The results were obtained using low-concentration CO2, equivalent to exhaust gas, and powered by light equivalent to sunlight for 24 hours. The researchers expect that this innovative way of producing biodegradable plastic could not only reduce CO2 emissions but also provide a way of reusing laboratory and industrial waste acetone. Their findings have been published in the journal Green Chemistry. Poly-3-hydroxybutyrateโ€”a biodegradable plasticโ€”is a strong water-resistant polyester often used in packaging materials, made from 3-hydroxybutyrate as a precursor. In previous studies, a research team led by Professor Yutaka Amao from the Research Center for Artificial Photosynthesis at Osaka Metropolitan University found that 3-hydroxybutyrate can be synthesized from CO2 and acetone with high efficiency, but this was only demonstrated at higher concentrations of CO2 or sodium bicarbonate.
