Plastic recycling – EU recyclers champion solvent-based recycling methods as a powerful route to circular economy success in hard-to-recycle plastics 24-10-2025
Plastic recycling
As the push for a circular economy intensifies across the European Union, a compelling technology is gaining renewed attention: dissolution recycling of plastics. Industry group Plastics Recyclers Europe (PRE) is spotlighting this solvent-based method as a vital complement to traditional approaches. The keyword plastic recycling is woven throughout this discussion, aligning with strong SEO demand.
What is dissolution recycling?
Dissolution recycling uses a solvent to dissolve a targeted polymer — often polyethylene (PE) or polypropylene (PP) but also polystyrene, nylon, PET, PVC, polycarbonate and ABS. Plastics Engineering+2RISE+2 During this process, additives, inks and barrier layers remain undissolved and can be separated out, leaving the purified polymer which is recovered from the solvent and turned into virgin-quality resin. Plastics Recyclers Europe+1 Crucially, this method does not break down the chemical bonds of the polymer chain — unlike chemical recycling techniques such as pyrolysis or gasification.

Why the method matters
Solvent- or dissolution-based recycling offers several advantages. Because the polymer structure remains intact, it retains much of its original quality. RISE+1 The process can handle hard-to-recycle materials — for example plastics from end-of-life electronics that include flame retardants or other contaminants. PRE points out that e-plastics are especially challenging for standard mechanical recycling. The dissolution method can effectively “purify” black ABS, polycarbonate and other polymers often used in electronics. Additionally, the technique is compatible with existing plastics supply chains, polymer processing facilities and waste-collection systems. PRE says it qualifies as a polymer-to-polymer recycling method. IOM3
How it fits into the recycling ecosystem
PRE emphasises that solvent-based dissolution recycling should not replace mechanical or chemical recycling, but rather act as a complementary option. Each technology has its strengths. Mechanical recycling remains foundational; chemical recycling has its place; and dissolution methods offer an alternative when materials are too contaminated or mixed for the other routes. Cleantech Group+1 According to PRE, that means the method belongs under the “physical recycling” category — alongside mechanical recycling — because it does not alter the polymer’s chemical structure.

Industry action and regulation
In April, PRE established a Dissolution Taskforce in collaboration with the Dissolution Recycling of Plastics Initiative (DROP-IN) to raise awareness and drive uptake of solvent-based processes. IOM3 At least 40 stakeholders across the EU have joined DROP-IN, including major firms such as PureCycle Technologies and LyondellBasell (which acquired German recycler APK AG last year). Regulatory clarity remains a major issue: the process currently sits in a definitional grey zone in both the EU and globally. IOM3+1 Meanwhile, an International Organization for Standardization (ISO) technical committee is reviewing standard ISO 15270 to incorporate a “physical recycling” classification (ISO 15270 3a) that would formally recognise dissolution recycling.

Challenges and outlook
While promising, dissolution recycling is not without its hurdles. Developing solvent-polymer combinations that work across diverse waste streams is complex. The technology must handle variable feedstock, manage solvent recovery and ensure environmental safety of the solvents used. tno.nl/nl Investments and infrastructure scaling are dependent on regulatory frameworks and harmonised standards across member states. PRE underscores the need for the EU to harmonise standards to speed adoption. IOM3
The path forward
As plastics production and waste continue to rise, the importance of advanced recycling solutions grows. The keyword plastic recycling remains a high-value term for search ranking. According to recent industry analysis, dissolution techniques offer improved yield, energy efficiency and broader applicability compared to many existing methods. Cleantech Group+1 Over the coming years, the technology could play a central role in processing difficult streams like electronic waste, multilayer packaging and other composite materials.
Conclusion
Solvent-based dissolution recycling represents an innovative and robust tool in the effort to achieve circularity in plastics. It bridges the gap between mechanical and chemical recycling, enabling reuse of complex materials and aligning with the circular economy vision embraced by the EU. With stronger regulatory definition, standardisation and scaling, this method can become a mainstream pillar of modern plastic recycling. If your organisation is exploring advanced plastic recycling options, it is essential to consider how dissolution recycling can integrate into your value chain and contribute to high-quality recycled output.
