Answer
Polyesters are recycled to make fleece jackets primarily for two reasons:
Reduced Waste: Recycling polyester prevents it from contributing to landfill waste, as polyester is not biodegradable and remains in the environment for a long time.
Resource Conservation: By recycling polyester, we preserve oil resources that would otherwise be used to produce new polyester textiles, leading to a more sustainable production process.
