Poly(1,4-butylene succinate) is widely used in the production of biodegradable plastics, making it a key material in environmentally friendly packaging solutions. It is particularly valued in the manufacturing of compostable bags, food containers, and disposable cutlery, where its ability to break down naturally reduces environmental impact. Additionally, it finds applications in agricultural films and mulch films, which degrade in soil, minimizing plastic waste in farming. In the biomedical field, it is utilized for controlled drug delivery systems and as a material for absorbable sutures due to its biocompatibility and gradual degradation properties. Its versatility also extends to 3D printing filaments, where it serves as a sustainable alternative to conventional plastics.
