The growing plastic waste crisis is an environmental challenge requiring innovative, sustainable solutions. Waste management requires not only the implementation of the 3Rs Reuse, Recycle, and Reduce but also the development of innovative materials that can be safely returned to the environment. The Return to Earth approach developed by PT Greenhope Indonesia is one effort to provide plastic solutions based on biodegradable materials and biopolymers, serving as alternatives to conventional plastics.
This vision aligns with the research conducted by the Smart Genetics Research Group, led by Ganies Riza Aristya, S.Si., M.Sc., Ph.D., from the Laboratory of Genetics and Breeding, Faculty of Biology, Universitas Gadjah Mada (UGM). The research focuses on the development of polyhydroxybutyrate (PHB), a biopolymer with potential applications as a raw material for biodegradable plastics, using a recombinant yeast-based microbial cell factory. The research is funded through the Link & Match Grant and supported by the 2026 Research Commercialization Program for Model and Prototype Testing, which promotes the translation of laboratory-based research into more applicable technological developments.
As part of strengthening university–industry collaboration, the UGM research team has been working with PT Greenhope Indonesia since 2023, with the current phase focusing on completing a product prototype in November 2026 at PT Greenhope Indonesia’s Main Factory in Tangerang. The activity involved UGM student researchers Ihsanul Fikri Alfarizel and Diva Septiani, under the supervision of principal researcher Ganies Riza Aristya, S.Si., M.Sc., Ph.D., together with the PT Greenhope Indonesia research team.
The collaboration aimed to further develop bioplastic resin based on PHB produced by recombinant yeast. PHB resin developed through research at the Faculty of Biology UGM was brought to PT Greenhope for purification, material development, and further testing in collaboration with the Greenhope research team. The four-day collaboration resulted in five key outputs:
- Purified industrial PHB resin as a reference material.
- Purified recombinant yeast-derived PHB resin developed through UGM research.
- Industrial PHB biofilm with its dimensions and thickness characterized.
- Recombinant yeast-derived PHB biofilm with its dimensions and thickness characterized.
- Product packaging prototype, representing an initial material design for applications such as instant noodle seasoning sachets.
These five outputs represent an important initial step in bridging laboratory-scale research with the material development needs of industry. The transformation of PHB resin into biofilm and subsequently into a packaging prototype demonstrates the potential of recombinant yeast-derived PHB for further development as a more sustainable plastic material.
The collaboration between UGM and PT Greenhope Indonesia will continue through further research and testing, with the long-term goal of developing biodegradable plastic products based on PHB produced by recombinant yeast. This effort is expected to help reduce dependence on conventional plastics while strengthening the commercialization and application of biotechnology research in Indonesia.
This collaborative initiative also contributes to several Sustainable Development Goals (SDGs), particularly SDG 9: Industry, Innovation, and Infrastructure, through the development and commercialization of bioplastic technology; SDG 12: Responsible Consumption and Production, through the development of more sustainable alternatives to conventional plastic materials; and SDGs 13, 14, and 15, through the development of biodegradable materials with the potential to reduce the environmental impacts of plastic waste. Furthermore, the collaboration between the Faculty of Biology UGM and PT Greenhope Indonesia represents an implementation of SDG 17: Partnerships for the Goals by bringing together academic research capacity and industrial expertise to develop bioplastic solutions with real-world applications.
