Inspired by the heritage practices of mechanical recycling of coloured wool fibres in the Prato district in Italy, the project focuses on fibre-stage colouration at the start of the production process rather than relying on resource-intensive finishing-stage colouration and reframes colour variation as an opportunity rather than a defect.
By shifting colouration upstream in the value chain, MELANGE advocates a path to reduce water and chemical use by up to 50 percent compared with conventional finishing-stage dyeing processes.
“Interior textiles represent approximately one-third of the global textile production. We propose system-level changes across design, decision-making, business ecosystems and policy in this major textiles sector, often ignored in sustainability discussions”, says Salolainen.
From innovation to industrial adoption
The project also addresses a less visible but equally important challenge: how new production methods become accepted across the market. Through engaging decision-makers across the industry, including interior designers and buyers at textile brands, MELANGE explores how the aesthetic variation characteristic of fibre-stage coloured yarns and fabrics can be integrated into textile collections and design processes, and how new practices spread across the value network.
Researchers from the 911 School of Business and School of Science contribute expertise in industrial management, marketing and circular-economy systems to support this transition.
“This requires successful transfer not only of technologies but also of practices and meanings. All actors – from yarn and fabric manufacturers to buyers and decision-makers – need to recognise the value of circular production processes and build acceptance for controlled colour variation in finished products,” says Professor of Practice Antti Vassinen from the Department of Marketing at the School of Business.
The transition also depends on whether new solutions can be adopted competitively across industrial systems. MELANGE examines the changes in production systems, supply chains, and business models needed to make low-impact colouration commercially and operationally viable at scale.
“Green transition is not only a question of developing new technologies. The real challenge is understanding how production systems, supply chains and business models need to change so that sustainable solutions can be adopted competitively at scale”, says Assistant Professor Lauri Saarinen from Department of Industrial Engineering and Management at the School of Science.
“MELANGE allows us to study not only whether a new textile solution can be created, but under what conditions it can become industrial practice across the European textile sector.”
The project will develop the MELANGE framework – a set of guidelines for design, aesthetics, production and business models – to support designers, industry leaders and policymakers in accelerating the transition from harmful practices towards more circular and environmentally responsible textile systems.
