Papermaker's new range uses colours from plant extract otherwise wasted

James Cropper has launched a coloured paper range using dye derived from plant extract which would have otherwise been wasted. The English Lake District-based company claims the new Wainwright Colours from Nature range is a first for the modern papermaking industry, and is the latest in a list of innovations they have nurtured to create value from waste streams.

With plant-based dyes more commonly used in the textile industry, James Cropper point out the new collection promises environmental credentials without compromise on technical performance.

The first two shades, Limestone and Herdwick Brown, are both derived from rosemary residue, a waste stream in some food production. The rosemary is grown as an annual agricultural crop before the non-edible waste from the plant is extracted and upcycled into the dye, which is added to James Cropper's 100% FSC® recycled paper.

The latest innovation from the Kendal-based papermaker heralds the first step in developing more sustainable colour options sourced from renewable origins that can be replenished responsibly, including food waste and inedible plant sources.

The colours were created to celebrate James Cropper's partnership with The Wainwright Prize, an annual literary award for the best UK-based nature and global conservation writing. The colours are inspired by author Alfred Wainwright's love for the Lake District landscape and James Cropper's desire to protect it.

Joanne Storey, R&D Programme Lead at James Cropper comments: "Whether it's used coffee cups, food waste or other pre and post-consumer waste, by repurposing these valuable streams, we continue to support transition to a more circular economy.

"From the use of renewable materials and low impact manufacturing processes, to producing high quality products that are easy to recycle, we are committed to sustainability at every turn, and our expertise in colour is part of that.

"It's the first-time plant-based dyes have been used in modern papermaking; a breakthrough which marks the first step into the development of more natural colour options. We are investigating botanical dyes extracted from a wide variety of origins including plants, shells and fungi; and expect the range to expand significantly."

The Wainwright Colours from Nature range is available from stock in 350gsm, ideal for presentation packaging, business stationery and invitations. The natural dye technology can also be applied to bespoke projects through James Cropper's Tailor Made service.
