Driven by global carbon neutrality goals, bio-based compatibilizers are emerging as a key enabler for the green transition in the plastics industry. Sourced from renewable materials like plant oils, corn starch, and lignin, these compatibilizers utilize chemical grafting techniques (e.g., maleic anhydride grafting) to enhance the compatibility between biodegradable plastics (PLA, PHA) and conventional petroleum-based polymers. For instance, in food packaging applications, bio-based compatibilizers can improve the interfacial adhesion strength between PLA and PE by 40% while maintaining transparency and heat-seal properties.
According to the China Synthetic Resin Association, the global bio-based chemicals market reached 12 billion in 2023 and is projected to exceed 30 billion by 2030, with a CAGR of 12%. While Europe and North America lead in adopting bio-based plastics for automotive interiors and disposable tableware, Asian manufacturers are rapidly advancing their technologies to secure a competitive edge in the sustainable supply chain.
