In recent years, the textile industry has been looking to develop new processing possibilities in order to reduce the environmental impacts generated along the production chain. Among these, the search for alternative fibers from biodegradable residues stands out, as well as a reduction in the consumption of water and chemical reagents, the replacement of chemical by enzymatic processes, the use of natural dyes and treatment of effluents. Thinking about these issues, the BR-UK Network was created, which aims to map agricultural industry by-products with the potential to develop textile processes and products for conscious consumption and production within the context of the circular economy. This paper presents straw an abundant agricultural by-product of sugar cane in Brazil and wheat in the UK.
