Abstract

Textile industries contribute significantly to the economy of many developing countries. Every year, these countries export millions of dollars’ worth of textile products to developed countries. However, textile industries use expensive and corrosive chemicals that pose a significant threat to environmental quality and public health. This has led to serious concerns and necessitated the inclusion of safer and environmentally friendly alternatives. Consequently, bio-based processing has created a new approach utilizing biotechnological advances. This article uses evidence from the scientific literature to examine the application of industrial biotechnology in textile-processing industries, which includes enzymes, as a sustainable alternative to the harsh toxic chemicals currently used in textile processing. The article draws on evidence that enzymes offer a competitive advantage over chemicals with less resource requirements (energy and water), reduced emission and less waste. Due to high specificity, enzymes produce minimum byproducts. The implementation of enzymes in textile processing could offer environmental benefits, and improve public health and the sustainability of textiles and apparel. This article contributes to critical awareness by providing succinct information about major enzymes used in textile processes to improve the performance of textile materials, thus contributing to changes in behaviours and attitudes towards textile processing and environmental sustainability. This can assist textile manufacturers and governments in the developing world in campaigns to promote biotechnologies for environmental sustainability.
