Overview

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.

Benefits

Operation and Application Requirement

The technology involves mechanical and chemical treatments to break down cotton-rich textile waste into cellulose pulp. The process is scalable and can be integrated into existing fibre production systems. It is particularly effective for post-consumer cotton waste. The resulting pulp has consistent quality and can be used in fibre spinning, making it suitable for regenerated cotton fibre production.

Sustainable Material Alternative

Circulose supports the use of regenerated cotton fibres as a sustainable alternative to virgin cotton and synthetic fibres. By reusing cotton waste, it reduces the need for new raw material extraction and minimizes the environmental impact of cotton farming, which is often water- and pesticide-intensive. This aligns with the industry’s shift toward circularity and resource efficiency.

Practical Applications and Case Sharing

Circulose has been applied in several pilot and commercial projects with textile brands and recycling partners. For example, Spinnova has collaborated with clothing manufacturers to produce new garments from old cotton waste, demonstrating the viability of the technology in real-world production. These initiatives highlight how the fashion industry can adopt circular supply chains and reduce reliance on virgin materials.

Application Tips

The implementation of Circulose shows great promise in closing the loop in cotton production. It is a market-ready solution that can help fashion and textile enterprises reduce waste and improve their environmental performance. However, success depends on effective collaboration across the supply chain, including waste collection, sorting, and integration into fibre manufacturing. It is a key example of innovative manufacturing and responsible raw material sourcing.
