YKK’s range also includes its GreenRise zipper, which replaces polyester made from conventional fossil fuels with plant-based plastic, thereby reducing fossil fuel consumption and CO2 emissions in the product cycle. The plant-derived polyester used is made from molasses, the by-product generated in the sugar production process.

Also included in the collection are environmentally friendly snaps and buttons using a new finishing process that reduces thermal energy, water usage, and toxic chemicals and waste.
