From local actions to industrial innovations: SOLSTICE shares mid-project results

Since its launch in May 2024, the SOLSTICE project is accelerating the transition from linear models to circular regional ecosystems in the textile industry, focusing on four key territories: Grenoble-Alpes Métropole (France), Berlin (Germany), Prato (Italy), and Catalonia (Spain). By mid-project, SOLSTICE has already revealed both regional disparities and promising solutions to strengthen textile repair, reuse, and recycling infrastructure.

Mapping the circular textile landscape in Europe

SOLSTICE began with an in-depth territorial analysis led by Circle Economy, examining how local textile systems operate across the four regions. The findings revealed significant geographic imbalances: circular services such as repair, reuse, and recycling remain largely concentrated in urban centres, leaving suburban and rural areas underserved.

The analysis also confirmed that a uniform approach to circularity is ineffective. Each territory operates within a distinct economic and infrastructural context. While Berlin and Grenoble are primarily consumption hubs focused on creative repair , Prato is defined by its industrial recycling capacity. Meanwhile, Catalonia collects high volumes of textile waste but still relies heavily on landfills due to a lack of reuse infrastructure.

These insights underscore the need for region-specific strategies to effectively scale circular textile solutions across Europe.

Engaging citizens in circular textile practices

Building on the territorial analysis, particularly regarding infrastructure access and public habits, SOLSTICE launched targeted pilots designed to actively involve citizens in the circular economy.

In Berlin, the project via Circular Berlin introduced the REPAIR DEAL, a pilot that encourages citizens to repair denim rather than discard it by combining a digital bonus system with local repair services. Meanwhile, in Prato, the Municipality of Prato addressed engagement through a gamified app called greenApes. Co-designed with citizens, the app maps local reuse services and rewards sustainable behaviours, allowing users to convert points into discounts or donations to social projects.

These pilots demonstrate how behavioural change, supported by digital tools and local services, can significantly increase participation in circular textile practices.

Advancing industrial recovery pathways

Alongside these citizen-focused initiatives, SOLSTICE partners achieved significant technical advancements addressing the most complex challenges of sorting and recycling identified during the ecosystem mapping phase.

Automated sorting: Pellenc ST successfully tested automated sorting lines on post-consumer textiles, producing high-quality feedstock for chemical recyclers with PET purity reaching greater than 96%.

Elastane removal: Addressing complex blends, Next Technology Tecnotessile developed a thermo-chemical process that selectively removes elastane from mixed fabrics, enabling the recovery of polyester and polyamide for reuse.

Decision support: To optimise these processes, Techtera launched Valoramix, a tool that uses economic simulation to help professionals visualise flows and identify the most viable valorisation pathways.

By starting with a clear look at how different regions operate, SOLSTICE connects local citizen action with large-scale industrial solutions. The project proves that moving to a circular textile industry isn't just about one fix, it requires better data, consumer support, and advanced sorting and recycling technology working together.

As part of a consortium of 24 partners working on the project, Textile ETP is leading the activities related to ECOSYSTEX (an initiative fostering collaboration among EU projects focused on textile circularity) and is developing it into a lasting European Community of Practice for innovation in textile circularity and sustainability. Textile ETP is also coordinating the dissemination and communication activities for SOLSTICE, overseeing the project’s visual identity, website, newsletter, and social media.

Additional details and visual documentation of the project’s activities and pilot actions are available in the accompanying PDF, which includes photographs from across the four pilot territories.

Textile ETP wraps up T-REX's Policy Roundtable

The T-REX project’s policy roundtable in Brussels on November 12 was a pivotal gathering of experts and leaders committed to advancing Europe’s sustainability efforts. Concluding the event, Secretary General Lutz Walter reflected on the discussions and emphasized the core themes that resonated throughout the day.

Industrial scale meets verified governance: RE&UP is now B Corp™ certified

RE&UP, the circular-tech transforming global textile waste into high-volume Next-Gen materials, has officially become a Certified B Corporation™. The milestone establishes the industrial recycler among a select group of manufacturing infrastructure providers verified as meeting B Lab Standards for social and environmental performance, transparency, and accountability.

Recover™ and Ünteks Group partner to scale recycled cotton in knitwear

Recover(TM), a global producer of low‐impact, high‐quality recycled cotton fiber, announces a new partnership with Ünteks Group, a vertically integrated textile manufacturer based in Turkey. The collaboration focuses on the development of circular knit fabrics and garments, combining Recover’s recycled cotton fiber with Ünteks Group’s integrated capabilities across knitting, dyeing, printing, and garment production.

ALADIN paves the way for circular and demand-driven textile production in Europe

Textile production can be organized sustainably by utilizing short supply chains and preventing overproduction. This can already be achieved today by intelligently connecting and efficiently utilizing existing infrastructure. At the same time, production becomes circular when innovative technologies and materials are used that enable high-quality recycling. The ALADIN research project, launched in May 2026 and co-funded with five million euros under the EU Horizon Europe program, is creating the conditions for this.

Ence and ShareTex begin initial testing of the ATENEA innovation project to promote textile recycling in Spain

Ence and ShareTex are making progress on the Atenea R&D project, which aims to develop a complete value chain for textile recycling in Spain. Specifically, the goal of the ATENEA project—which is funded by the Center for Technological Development and Innovation (CDTI)—is to connect all the necessary stages for the recovery of textile waste, from collection and management, through recycling and transformation into new raw materials, to their incorporation into new textile products.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.
