Innovative leather alternatives are emerging as sustainable solutions to some of the most pressing environmental challenges we face today. One remarkable creation comes from Vietnamese designer Uyen Tran, who has developed a versatile bio-material known as Tômtex. This innovative textile is crafted from food waste, specifically seafood shells and coffee grounds, and is designed to emulate traditional animal leathers.
The name “Tômtex” is derived from the Vietnamese word for shrimp, reflecting its primary ingredient—discarded seafood shells. According to Tran, this biodegradable material is not only durable but also retains the softness necessary for hand-stitching and machine sewing. “Leather is used in many applications across diverse industries, but the pollution caused by leather production is a significant issue,” Tran notes.
Facing the challenge of waste, Tran aimed to create a product that uses natural resources effectively. The global food and drinks industry generates a staggering amount of waste each year, including tons of seafood shells and coffee grounds. Collaborating with suppliers in Vietnam, Tran extracts a biopolymer known as chitin from the shells of shrimp, crab, and lobster, as well as fish scales. This biopolymer, combined with surplus coffee from her kitchen and local cafes, forms the backbone of Tômtex.
Color options for this innovative textile come from natural pigments, such as charcoal and ochre. Notably, the material’s finishing process is uniquely creative; instead of being cured in flat molds, Tran utilizes clay or 3D printing to produce textural variations. This technique allows her to create finishes that mimic various animal leathers, including snakeskin and crocodile patterns, all while providing a sustainable alternative.
With Tômtex, Tran’s efforts highlight the potential of food waste as a resource, paving the way for enhanced sustainability in the fashion industry while tackling the crucial issue of pollution generated by traditional leather production.
