Dupont launched an environmentally friendly biodegradable polyester product named Biomax in Taiwan last week. Biomax has many advantages over traditional materials; the integration of biotechnology and material science in Biomax’s hydro/biodegradable polyester form allows it to decompose without harming the environment. During the final stage of decomposition the new material naturally converts into carbon dioxide and water. Other than biodegradability, Biomax also has extraordinary stability and Dupont plans to use the material for many applications in everyday life. If Dupont gets its way, in the near future Biomax will become a familiar and important environmentally friendly material. The introduction of Biomax at the same time as DuPont’s 200th anniversary marked a significant moment in the company’s history. DuPont has always been a leader of innovation and environmental protection with their research into science technology.

Biomax is a thermoplastic material that has excellent processability for a wide variety of applications. Biomax, DuPont hopes, will help reduce the number of harmful PET products, which in turn will lead to a less polluted planet. “Regardless of its biodegradability, a material must be easy to process if its scope of application is not to be limited. Biomax is a sophisticated material that can be film processed, injection molded or vacuum formed”, said Carl Lathon, manager of Dupont Biomax Venture. Biomax is ideal for biaxially oriented films, blown films, various molded plastic articles, bottles, textiles and non-woven fabrics. It can be processed by heat sealing and high frequency heat sealing. Mureo Kaku, Biomax technical marketing manager of Asia stated that Biomax was found to be harmless to the environment at every stage of the decomposition process.

Researchers have performed a series of tests to determine the environmental impact of Biomax, including it’s effect on plant germination and seeding emergence, earthworm weight gain and mortality, and microbial population density. The flexibility of Biomax is immense. Because it can be made into fibers, films or resins, it is suitable for a wide range of single-use products such as domestic wipes, yard waste bags, blister packs, and disposable eating utensils. Biomax can be used to create many new products from geo-textiles, agricultural films, seed mats and plant pots, to bags that cover ripening fruit.
