A collaborative Japanese research team has created a new class of biobased polymers that outperform conventional commodity plastics in tensile strength. The materials, developed by Professor Kotohiro Nomura at Tokyo Metropolitan University, are made from inedible biorenewable sources.
The poly(ester amide)s exhibit better mechanical properties in film form than polyolefins, which are widely used in packaging and containers. Crucially, these polymers can be easily chemically recycled, addressing a major environmental drawback of traditional plastics.
Key partners in the work include Senior Researcher Hiroshi Hirano and Director Seiji Higashi at the Osaka Research Institute of Industrial Science and Technology. Associate Professor Hiroki Takeshita of The University of Shiga Prefecture also contributed to the research.
The development could offer an alternative to petroleum-based plastics that dominate global production. However, scaling these materials from laboratory testing to commercial manufacturing remains a significant hurdle. Cost competitiveness with established polyolefins has not yet been demonstrated.
The findings were published in a peer-reviewed scientific journal. No timeline for industrial adoption has been announced.
