Answer
Polyesters are recycled to make fleece jackets for various reasons:
Sustainability: Recycling polyesters reduces waste and prevents them from ending up in landfills, contributing to a more sustainable environment.
Resource Efficiency: It preserves oil supplies since virgin polyester is derived from petroleum, thus lowering the demand for new raw materials.
Cost-Effective: Using recycled materials can often be cheaper, helping to reduce production costs for manufacturers.
