In this paper, we discuss the potential of using traditional knowledge of natural dyes for more sustainable development processes in textile design. Our aim is to help foster a green transition through responsible consumption and production. We investigate the potential for implementing natural dye processes from craft to industrial processes to replace synthetic dyes. We adopt a systematic approach to dyeing and printing with food waste, including walnut shells, avocado skins and onion skins, specifically exploring colourfastness. We have observed that craft methods tend to be ‘forgotten’ due to the zeal for industry­alization and the standardizing of products to ensure quality requirements. From students and business partners, we experience requests for natural dyes; however, we are challenged to document colour­fastness. Knowledge and documentation are of high importance when we intend to convince industry to learn from traditional crafts. Through a systematic investigation testing traditional recipes and variations in dyed textiles, we experience how textiles perform. Through iterations based on the results, we continue with further experiments and simultaneously discuss whether both the consumer and the industry have to look at quality requirements from a conventional perspective. We argue that current expectations regarding colours and standards must change. Facing radical changes to the way we live, produce and use products, it is important to critically examine our approach to conventional industrial production. In our research, we built knowledge generation on cultural heritage and traditional craft. We argue how this becomes a societal asset influencing users’ behaviour and creates awareness towards sustainable changes in the design and use of textiles.
