From November 16 to 20, 2026, the 75th Annual Meeting of ISO/TC 61 — the International Organization for Standardization's Technical Committee on Plastics — will be held in Hangzhou. Around 200 delegates from 36 member countries will gather to discuss the sustainability of plastics worldwide and the development of international standards. Among the co-organizers is a company rooted in Xiaoshan, Hangzhou: BioStar (Hangzhou) Biomaterials Co., Ltd. (BioStar). Together with the Chenguang Research Institute of Chemical Industry, PetroChina, Sinopec, the Hangzhou Standardization Research Institute, and other organizations, BioStar will co-host this international event.
ISO/TC 61 is the most influential international standardization body in the global plastics industry. Since its founding in 1947, it has led the development of 770 international standards, and its annual meeting is the platform where experts from around the world shape the direction of the plastics industry. For a local company to stand on the stage of international standardization takes real technological strength and industrial depth. BioStar specializes in the R&D and industrialization of bio-based, biodegradable, and compostable materials, with a full value chain spanning biomass resource utilization, material synthesis and modification, packaging production, and the closed-loop treatment of organic solid waste. With an annual capacity of 10,000 tons, it is a globally leading provider of customized biomaterial solutions.
The company is led by its founder and chairman, Dr. Weipeng Liu. Professor Ramani Narayan of Michigan State University — a founding figure in bio-based and biodegradable materials — serves as scientific advisor, and the company works with Zhejiang University and the Biomaterials Research Center (BMRC) at Michigan State University, among others. BioStar holds 38 patents, and its products have passed international certifications including BPI, TÜV, ASTM, and FDA. Multiple proprietary technologies have been commercialized, and its technical and commercial capabilities span China, the United States, and Europe. In Hangzhou, the company has built an R&D and industrialization platform anchored in Zhejiang University's polymer laboratory, and it operates production and industrialization bases in Tonglu, Shaoxing, Huzhou, and Ningbo. Its products serve logistics, catering, high-end consumer goods, daily film and bag products, agriculture, medical care, and 3D printing, and it works with well-known brands and industrial customers at home and abroad, including Wilson, Burger King, JD.com, and Yunda.
From serving global brands to co-hosting an international standards meeting, BioStar's journey is a snapshot of how Hangzhou companies are winning a voice on the world stage through technological innovation. Looking ahead, BioStar will grow from bio-packaging into a biomaterials platform and a global bio-economy platform — letting every package return to nature, and building a new calling card for Hangzhou in green materials.
