Fashion retailer Esprit has unveiled a collection of garments dyed using upcycled leftovers of almond shells, rosemary, bitter orange, and beetroot.
The Hong Kong-listed firm, which has a presence in 40 countries worldwide, is the latest to utilise the plant-based EarthColors dyes developed by textile chemicals specialist Archroma.
Sourced from up to 100% renewable resources, the EarthColors range was developed using non-edible waste products from agriculture and herbal industries to replace petroleum-derived raw materials, which are the conventional raw materials used to synthesise dyes currently.
The colours available in Esprit’s ‘I am Sustainable’ capsule collection are made from the non-edible parts of nutshells, almond shells, rosemary, saw palmetto, bitter orange, and beetroot left over from agriculture industry or herbal extraction.
“Colours traditionally made with plants come with some limitations in terms of colour reproducibility, fastness and they require huge amounts of plants to produce the quantities needed at industrial scale,” says Kristina Seidler-Lynders, manager social and environmental sustainability at Esprit.
She adds Archroma’s EarthColors provided a technology that would allow it to explore authentic colours synthesised from plants rather than petroleum.
The high-performance dyes have also been used by Ternua, G-Star Raw, Kathmandu, and Patagonia.
