Thermore Tackles Textile Waste with High-Performance Insulation

MILAN, Italy – March 11, 2026 – Italian thermal insulation specialist Thermore has unveiled a groundbreaking product aimed squarely at one of the fashion industry's most pressing environmental challenges: textile waste. The company today launched Ecodown Fibers T2T, a high-performance, free-fiber insulation made from 100% recycled materials, with the majority sourced directly from textile production waste.

This innovation represents a significant advancement in the push for a circular economy, transforming discarded polyester materials into a premium component for outerwear and apparel. For over 50 years, the Milan-based firm has been a key supplier to major fashion and outdoor brands, and this new product reinforces its long-standing commitment to sustainable material science.

The Looming Crisis of Textile Waste

The launch of Ecodown Fibers T2T arrives at a critical moment. The global apparel industry is grappling with a colossal waste problem, generating an estimated 92 million tonnes of textile waste annually. Projections indicate this figure could surge to 148 million tonnes by 2030 if current trends continue. The vast majority of this waste—around 85%—is destined for landfills or incineration, contributing to significant greenhouse gas emissions and environmental degradation.

A central challenge in textile recycling has been the prevalence of "downcycling." This process converts waste materials into new products of lower quality and value, such as industrial rags or carpet padding. While it diverts some waste from landfills, it represents a dead end in the material lifecycle, failing to create a truly circular system. Less than 1% of the material used to produce clothing is currently recycled back into new apparel, a statistic that underscores the urgent need for high-value recycling solutions.

A Circular Solution to a Linear Problem

Thermore's Ecodown Fibers T2T directly confronts the issue of downcycling. The insulation is composed of a clever blend of 100% recycled polyester fibers: 80% is derived from post-industrial textile waste, and the remaining 20% comes from post-consumer PET bottles. By converting textile scraps from the supply chain into a high-quality insulation material, Thermore is creating a textile-to-textile solution that preserves material value.

This development is the culmination of years of focused research. "I have personally coordinated the Thermore research group for years, and the theme of circularity and textile-to-textile has long been the subject of study by our team," stated Patrizio Siniscalchi, Managing Director of Thermore. He noted the company's long history in the field, referencing its pioneering use of recycled PET bottle fibers over four decades ago. "Ecodown Fibers T2T is already the second generation of padding we have produced using these important resources," Siniscalchi added, highlighting the company's sustained investment in revaluing textile waste.

Performance Engineered from Recycled Materials

For any sustainable material to gain widespread adoption, it must meet or exceed the performance of its conventional counterparts. Thermore emphasizes that Ecodown Fibers T2T was engineered not just for its environmental benefits, but for its technical excellence. The company asserts that the product delivers the same high quality associated with its entire portfolio.

The insulation boasts a high loft and exceptional softness, ensuring comfort and warmth for the end user. Its versatility is a key selling point for designers and manufacturers; the free fibers can be blown into baffles, placed inside quilted panels, or even applied by hand. Furthermore, its internal structure is engineered for long-term stability, a critical feature that minimizes clumping and cold spots after repeated use and washing, thereby extending the life of the garment.

The Gold Standard of Sustainability Certifications

To provide transparent verification of its environmental and safety claims, Ecodown Fibers T2T is backed by a suite of internationally recognized certifications. The product is certified by the Global Recycled Standard (GRS), which validates the recycled content and ensures traceability throughout the entire supply chain, from waste collection to the final product.

It also holds Bluesign® certification, a rigorous standard that evaluates the entire manufacturing process to eliminate harmful substances from the outset and ensure resource-efficient, environmentally responsible production. Complementing this is the OEKO-TEX® Standard 100 certification, which guarantees that the final product is free from a long list of substances that could be harmful to human health. Together, these certifications provide brands and consumers with robust assurance of the product's integrity, safety, and sustainable origins.

A Legacy of Innovation in a Competitive Market

The introduction of Ecodown Fibers T2T is the latest milestone in Thermore's long history of sustainable innovation. As one of the first companies to introduce insulation made from recycled PET bottles, Thermore has consistently positioned itself at the forefront of responsible material development. This new product differentiates itself in a growing market of sustainable insulations—which includes natural options like wool and other recycled materials like cellulose—by specifically targeting the vast and underutilized resource of textile waste.

By creating a high-value outlet for materials that would otherwise be downcycled or discarded, Thermore is not just launching a new product but also championing a new paradigm for the apparel industry. Ecodown Fibers T2T represents a tangible step for the fashion and sports sectors, offering a concrete path where responsibility, performance, and style are woven together.
