Lotte to develop seawater-degradable PHA-material

South Korea’s Lotte Chemical Corp. (Seoul) plans to develop a decomposable bioplastic material in seawater for production based on petrochemicals for the first time in the global industry to cut carbon emissions.

Lotte Chemical recently said that it will develop polyhydroxyalkanoates (PHA), an eco-friendly bioplastic material that degrades 100 % in seawater with a target of commercialization by 2023. The petrochemical unit of Lotte Group is conducting research on the material with a local university in Seoul supported by the Ministry of Science and ICT as well as the National Research Foundation of Korea.

PHA, used in packaging materials, medical products, and cosmetics containers, is currently produced only with microorganisms. It is hard to secure raw materials, resulting in low outputs of PHA and higher prices, since microorganisms, which need processes such as cultivation and fermentation, are used for production.

The commercialization of PHA production based on petrochemicals will allow mass production with petrochemical and biomass raw materials that are easy to procure, Lotte said. That will improve price competitiveness. Demand for biodegradable plastic materials continued to grow with consumption expected to more than double to 2 million tonnes in 2026 from 970,000 tonnes in 2020, said Lotte, citing an industrial forecast.

Earlier this month, Lotte unveiled a plan to invest USD 502.4 million in eco-friendly materials plants at one of its domestic petrochemical complexes.
