Why are zips not Eco friendly?

Zippers are often made from materials like plastic or metal, which can have significant environmental impacts. The production process for these materials can involve harmful chemicals and high energy consumption. Additionally, zippers are not easily recyclable, contributing to landfill waste when garments are discarded. Furthermore, the durability of zippers can lead to longer-lasting items, which is beneficial, but the materials still pose an ecological challenge at the end of their life cycle.
