Poly(1,4-butylene succinate) is widely used in the production of biodegradable plastics, making it a key material in environmentally friendly packaging solutions. Its ability to break down naturally under composting conditions makes it ideal for single-use items like bags, food containers, and agricultural films. In the medical field, it is utilized for creating absorbable sutures and drug delivery systems due to its biocompatibility and controlled degradation properties. Additionally, it serves as a component in mulch films for sustainable farming practices, helping to reduce plastic waste in agriculture. Its versatility and eco-friendly nature also extend to 3D printing applications, where it is used to produce biodegradable prototypes and products.
