Introduction
With growing global concern over climate change and environmental degradation, the Hong Kong fashion and textile industry is facing increasing pressure to adopt more sustainable practices. At the same time, this transition presents new opportunities for the industry to enhance its competitiveness and strengthen long-term resilience. As an important player in global fashion trade and supply chains, Hong Kong is well positioned to support and benefit from this shift. In response, the Institute of International Sustainable Development (ISD) launched the project, “The Guide for Sustainability Journey – A Practical Toolkit for Hong Kong Fashion and Textile Industry,” with funding support from the Trade and Industry Organisation Support Fund of the Trade and Industry Department of the HKSAR Government.
Building on the findings of the previous project, this toolkit has been developed as a practical and user-friendly online resource for local enterprises, particularly small and medium enterprises (SMEs). Its purpose is to help businesses better understand sustainable technologies and solutions and apply them to their own operations. The toolkit focuses on three key improvement areas identified by the industry: handling of surplus products, design and manufacturing, and the selection of greener raw materials. It also provides accessible information on market-available technologies, practical implementation guidance, case sharing, updated policy and funding information, and customised booklet functions. Through this study and toolkit, the project aims to equip enterprises with practical knowledge and tools to support informed decision-making, encourage the adoption of green technologies, meet evolving international requirements, and advance their sustainability journey.
Circulose
Circulose, developed by Spinnova, is a sustainable solution that enables the recovery and reuse of cotton fibres from textile waste. It is a circular technology designed to support the fashion and textile industry in addressing the challenge of post-consumer and post-industrial waste by transforming it into high-quality, regenerative cotton pulp. This pulp can be used to produce new, 100% cellulose-based fibres through a closed-loop process.
Colorifix
Colorifix is a UK-based biotechnology company that utilizes genetically engineered microbes to produce natural dyes and apply them to textiles through a sustainable, water-free, and chemical-free process. This pioneering biofabrication technology is classified under both sustainable material alternatives and innovative manufacturing techniques. It specifically addresses the critical industry needs for responsible raw material sourcing and highly energy-efficient production processes, offering a radical departure from traditional, resource-heavy dyeing methods.
Cooltrans
Prosperity Textile’s World of Wonder (WOW), powered by its Cooltrans technology, is a patented cold transfer printing solution designed to enhance sustainability in textile printing. It uses semi-bleached fabric as a base and enables double-sided, high-colour vibrancy printing in one process, reducing the need for multiple printing stages. The technology significantly lowers water and energy consumption while minimising chemical dye usage, making it a greener alternative to traditional methods. By integrating cold transfer printing, Prosperity Textile supports eco-conscious fashion brands in reducing their environmental footprint without compromising design quality and flexibility. This case study highlights how innovative printing solutions can be applied at scale, offering a replicable model for the fashion industry’s green transition.
eDesigner
eDesigner is a state-of-the-art digital denim finishing and wash design platform developed by Jeanologia, a global leader in eco-innovative textile technologies. As a highly effective design tool, it champions sustainable design practices and energy-efficient manufacturing techniques, particularly within the denim sector. The platform empowers brands and manufacturers to create and visualize complex denim washes and finishes digitally. By perfecting the aesthetic in a virtual environment first, these designs can then be applied through a closed-loop, water-efficient system, drastically reducing the environmental footprint of physical production.
Fashion Clinic
Fashion Clinic provides a Circular Design and Upcycling Solution focused on textile waste remediation. Unlike traditional manufacturing, it treats existing garments as "patients," using redesign, reshaping, and repair techniques to transform pre-consumer deadstock and post-consumer waste into high-value, contemporary fashion, effectively closing the loop in the textile lifecycle.
