Austria-based Lindner-Recyclingtech GmbH has partnered with global consumer products giant Procter & Gamble (P&G) to develop a solvent-based extraction process. This innovative method is designed to eliminate non-intentionally added substances (NIAS), odors, adhesives, and printing inks from polymer recycling chains.

The companies describe their new Flexloop process as “revolutionary mechanical recycling technology.” It significantly enhances the purity levels of post-consumer recycled plastic, unlocking entirely new market opportunities, particularly in sensitive packaging applications within the cosmetics and personal care industries.

For us, Flexloop is a logical and necessary development in mechanical recycling and an extension of cold and hot washing.

At the 2025 K Fair held this October in Germany, Lindner and P&G presented Flexloop, highlighting its modular system that can be seamlessly integrated into existing Lindner washing and recycling systems. This integration provides recyclers with exciting new opportunities and access to emerging sales markets.

Currently, secondary resin derived from post-consumer plastic is mainly used in applications such as park benches and rubbish bags. While chemical recycling has been considered as an alternative, Lindner notes that the high investment and energy costs render this method less commercially appealing.

We foresee a growing demand for high-quality recycled resin that is suitable for a wide range of flexible film applications, so we are excited for the introduction of Flexloop, an innovation our researchers developed as an option for upcycling a wide range of plastic materials through mechanical solvent extraction.

The modular design of the Flexloop unit allows it to be integrated into nearly any Lindner washing and recycling line, enabling recyclers to utilize their existing infrastructure and incorporate Flexloop into their current processes. According to Lindner, the capital and operational expenses associated with Flexloop are significantly lower compared to chemical recycling.
