From the Sector

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, and SELENIS, a leading supplier of high-quality specialty polyester solutions, have signed a Letter of Intent to cooperate in the production of PETG. By leveraging CARBIOS’ enzymatic depolymerization technology and Selenis’ expertise in polymerization, the companies aim to develop a premium, sustainable PETG material made from PET waste for the Cosmetic and Healthcare packaging sectors across Europe and the U.S. This partnership follows a two-year collaboration between the two companies and represents a significant advancement in the plastic recycling industry.

PETG is an indispensable packaging material in both the cosmetics and healthcare industries due to its exceptional clarity, durability, mechanical and chemical resistance. CARBIOS’ enzymatic depolymerization solution breaks down all types of PET waste into PTA and MEG monomers, which are then transformed into PETG through Selenis’ advanced polymerization processes. Thanks to the purity of these monomers, PETG issued from biorecycling presents the same properties as virgin PETG, allowing for products packaged in thick, molded pots and lids to be protected and presented attractively. In the medical and pharmaceutical industries, PETG properties are also critical for guaranteeing top packaging performance, sterility, transparency and optical brightness, making it an ideal choice for complex medical device packaging, pharmaceuticals blisters, or any other packaging of diagnostic equipment. The material’s value is therefore further underscored by combining a sustainable recycling solution whilst guaranteeing all needed properties, aligning with consumer sustainability demands and stringent regulatory requirements.

CARBIOS and Selenis’ partnership is the result of extensive pilot and industrial polymerization trials that have refined the quality of the end product. The result is high-specialty PETG grades issued from biorecycling that meet the strict requirements of sectors like cosmetics and healthcare, where Selenis has a strong presence through its Selcare brand.
