As sustainability transitions from merely a buzzword to a crucial business necessity, textile recycling has emerged as a vital area in circular manufacturing. Each year, millions of tonnes of clothing and industrial fabrics are discarded into landfills or incinerators—creating a waste stream abundant in recoverable materials like polyester and cotton.

In this landscape, the new collaboration between Erema Group, a global leader in plastic and polymer recycling machinery, and BlockTexx Pty Ltd, an Australian startup specializing in fiber recovery from blended textiles, signifies a pivotal moment in the global textile recycling initiative.

A Game-Changing Alliance

This partnership, formally established during the K 2025 trade fair in Düsseldorf, Germany, represents more than just a financial commitment. It’s a strategic alliance aimed at expediting scalable solutions for post-consumer textile recycling, merging expertise in technology, engineering, and sustainability.

Why This Partnership Matters

The textile industry has faced a persistent issue with poly-cotton blends—fabrics comprising both polyester (PET) and cotton fibers. These materials are notoriously challenging to separate and recycle effectively. However, BlockTexx has developed a proprietary method to tackle this problem.

By collaborating with Erema, BlockTexx gains access to industrial-scale recycling technology, advanced process engineering, and the capacity for global scaling. For Erema, this partnership broadens its portfolio, extending beyond traditional plastics recycling into fiber-to-fiber circularity—a significant strategic pivot toward textile recycling.

Erema’s Strategic Expansion into Fiber Recycling

Over the last decade, Erema has established a strong reputation in bottle-to-bottle PET recycling. Now, the company is leveraging its technological and R&D capabilities to venture into textiles, an industry where fiber recycling remains nascent.

Erema’s long-term vision is to derive half of its business from the fiber sector, reflecting its belief in the enormous growth potential of textile recycling. The partnership with BlockTexx accelerates this vision.

BlockTexx: Creating New Value from Poly-Cotton Waste

Founded in Australia, BlockTexx has developed one of the world’s most advanced textile recycling facilities. Its initial plant, located south of Brisbane, processes 10,000 tonnes of textile waste annually, with plans for a second facility in New South Wales that will handle 50,000 tonnes per year.

BlockTexx’s innovative technology can separate post-consumer poly-cotton blends into two essential raw materials:

• rPET (recycled polyester)
  • Ideal for re-spinning into new fibers or packaging.
• Cellulose powder
  • Sourced from cotton, used in industrial or chemical applications.

This dual-output process not only diverts textile waste from landfills but also reintegrates high-quality materials into the circular economy.

How the Partnership Works in Practice

The collaboration includes Erema becoming a minority stakeholder in BlockTexx and offering technical support through its Intarema FibrePro:IV system—specialized recycling technology that transforms recovered PET into usable pellets.

During trial runs, recovered PET from BlockTexx’s Australian plant was transported to Erema’s headquarters in Austria, where it was pelletized and reformed into new textiles and T-shirts—demonstrating that the process works seamlessly from start to finish.

These initial sample products were proudly showcased at Erema’s outdoor exhibition during the K 2025 trade fair, symbolizing the emergence of large-scale textile-to-textile circularity.

The PET Equation: Bottles, Fibers, and Circular Loops

One of the most intriguing aspects of this partnership is its broader influence on the PET recycling ecosystem.

According to Hackl, the PET fiber industry is three times larger than the PET bottle sector. This discrepancy creates a recycling paradox: many PET bottles are downcycled into textiles rather than remaining within the bottle-to-bottle recycling loop.

By enhancing textile recycling technologies, Erema and BlockTexx aim to close the fiber loop, ensuring that more PET bottles stay in their own cycle while textile waste develops its own sustainable recovery pathway.

The collaboration between these two companies began at a textile trade show in Milan, where their teams discovered a shared vision for sustainable materials recovery.
