Crystal International Group is taking circularity to new heights with its latest denim collection which is made from circular fabrics and sees the cut waste upcycled into other apparel and accessories.
The Hong Kong-based manufacturing giant’s latest collection Second Life, which has been launched online, adopts recycled denim fabrics and sustainable materials to minimise wastage and keep materials in use.

“The collection goes beyond ‘Second Life’ and extends the circularity to even ‘Third Life’ by further regenerating the wastage from the circular fabrics to other denim items. The cut waste from Second Life denim is gathered and upcycled as the new kimono jackets, patches, and accessories to work towards zero wastage,” explains Miles Lam, assistant general manager of product development of Crystal Denim.
The line utilises recycled cotton, which is dyed with liquid indigo for further water and chemical reduction. Some key wastewater parameters such as chemical oxygen demand COD and total suspended solids can be reduced by over 60%, Crystal says.
It adds recycled denim fabrics can mitigate the environmental footprint of virgin denim fabrics production, particularly water consumption, with eco washing methods adopted in the finishing approaches without manual labour.
The whole collection of closed-loop denim made by recycled fabrics is certified with Recycled Claim Standard (RCS), as well as sustainable materials including Lycra T400 fibre with EcoMade technology and Repreve recycled polyester. With the chain of custody standards, certified materials are traceable along the supply chain.

The eco denim factory in China initiated the Second Life concept in 2020 and worked towards infusing pre-consumer cut waste and sorted scraps with a new life.
By reducing the use of new materials, Crystal Denim can reduce water and energy consumption from growing new cotton, which accounts for around 70% of water consumption and 10% of carbon emission throughout the product life cycle of denim jeans. By collaborating with the partnering mills, Crystal Denim has successfully developed ten denim fabrics for men and womenswear.
Compared with the traditional recycled denim fabrics, the Second Life fabrics are said to provide greater depth of colour and stronger intensity of weft yarn while maintaining durability.
In addition, all fabrics are launched in physical and digital format, and benefit product development including 3D virtual sampling.
