A domestic new materials technology company recently announced that its environmentally friendly, biodegradable injection-molding material has completed industrial-scale production, filling a significant market gap in China for high-performance, biodegradable injection-molding materials. Made primarily from corn starch and plant fibers, this material undergoes molecular structure optimization through advanced modification technologies. In natural environments—such as soil and seawater—it can fully degrade within 180 days, leaving behind only carbon dioxide and water with no environmental residue. At the same time, it boasts mechanical properties—tensile strength ≥25 MPa and impact strength ≥5 kJ/m²—that are comparable to those of conventional petroleum-based plastics, as well as excellent processing fluidity. This material is fully compatible with existing injection-molding equipment and requires no additional modifications.
The general manager of the company stated that after more than three years of R&D and pilot testing, this material has successfully obtained international biodegradability certifications such as the EU’s EN 13432 and the U.S. ASTM D6400. It is now being used in a variety of applications, including food packaging containers, disposable tableware, maternal and infant products, and gardening supplies. The first-phase project has an annual production capacity of 50,000 tons, with projected annual sales revenue exceeding 1 billion yuan. In the second phase, production capacity will expand to 150,000 tons, enabling the substitution of approximately 200,000 tons of conventional plastics and reducing carbon emissions by over 300,000 tons. As the “dual-carbon” policy continues to advance and environmental awareness grows, downstream enterprises’ demand for biodegradable materials is steadily increasing. The mass production of this material will provide crucial support for the green transformation of the injection molding industry and help address the challenge of white pollution.
