Biomaterials, the next frontier for the footwear supply chain

In the fashion sector, according to research by the Boston Consulting Group and Fashion for Good, materials account for approximately 30% of the cost of goods sold and over 90% of total emissions linked to extraction, processing and production. A disproportion that positions the transition towards next-generation materials – of biological origin or obtained through advanced biotechnology – among the strategic priorities on the fashion and footwear supply chain’s environmental agenda.

The forecasts outline a trajectory: by 2030, biomaterials could account for 8% of the global fibre market, equivalent to approximately 13 million tonnes, compared to the current 1%. A tenfold increase within just a few years that repositions bio-based research at the centre of the sourcing choices made by brands and manufacturers.

Italy is moving forward as an advanced laboratory for experimentation. In Campania, the Biologic laboratory has developed ScobySkin, a three-dimensional bio-film obtained from bacterial microorganisms derived from local fruit waste – apples, kiwis, oranges and grapes – already used in the costumes and jewellery of the San Carlo Theatre in Naples. Laboratory-grown leather-inspired materials allow carbon emission reductions of up to 87%, the elimination of methane and a dramatic reduction in water and soil consumption. Whilst acknowledging the natural sustainability of leather, a by-product of the food supply chain.

Applications that extend from fashion to footwear, furnishings and automotive, confirming the country’s role as a hub for sustainable innovation.

The industrial challenge remains. At ‘Materials+ Hong Kong’, during the NextGen Fashion Material TechTalk co-organised by The Mills Fabrica, ISA Next-Gen Materials, HKRITA and Material ConneXion, researchers, start-ups and industry leaders focused on the same question: how can promising materials be transformed into commercially viable, sustainable supply chains for fashion, footwear and leather goods. The gap between scientific discovery and industrial scale remains the real proving ground.

Large-scale adoption of biomaterials could reduce the cost of goods sold by up to 4% over the coming five years, making supply chains more resilient and competitive. For the Italian footwear cluster, already structured around artisanal know-how and supply chain integration, the prospect will depend on the ability to translate laboratory innovation into replicable industrial solutions throughout the entire production chain.

Next Thursday, we will be taking an in-depth look at 4s ETHIC, specifically the Version 1.0 Guidelines for a harmonised supply chain monitoring system.
