Dissolution and Depolymerisation Technologies: Advancing the Circular Plastics Economy
Dissolution Technologies for Recycling of Engineering Plastics and Commodity Plastics
Dissolution describes a solvent-based technology that is based on physical processes. Targeted polymers from mixed plastic wastes can be dissolved in a suitable solvent while the chemical structure of the polymer remains intact. Other plastic components (e.g. additives, pigments, fillers, non-targeted polymers) remain undissolved and can be cleaned from the dissolved target polymer. The session covers polymer extraction or purification from PS, PE, PP, and PVC and engineering plastics (e.g. ABS) through physical recycling using dissolution technologies.
Depolymerisation Technologies for PET
Assisted by solid or liquid chemicals as well as enzymes, the depolymerisation breaks PET waste, and even textiles into its building units (e.g. monomers) that can be fed back into polymer production. Learn more about solid-state hydrolysis, solvolysis, and enzymolysis.
Conclusion
Dissolution and depolymerisation technologies are essential advancements in driving the circular plastics economy by enabling efficient recycling of both engineering and commodity plastics. Dissolution, a solvent-based physical recycling process, allows targeted polymers like PS, ABS, PE, PP, and PVC to be dissolved and purified, while leaving contaminants such as additives, pigments, and non-target polymers behind. This preserves the polymer’s chemical structure, making it suitable for reuse. Depolymerisation, on the other hand, focuses on breaking down polymers like PET into their monomers using chemical or enzymatic methods. The monomers can be used as raw materials for the polymer production. Both technologies are key to addressing the challenges of plastic waste management by offering more sustainable and efficient recycling processes.

The Advanced Recycling Conference (ARC) 2024, scheduled for November 20-21 in Cologne, Germany, and online, is set to showcase cutting-edge developments in advanced recycling technologies. This premier event will bring together industry leaders, researchers, and policymakers to explore innovative solutions for various waste streams, including plastics, textiles, and e-waste. With nearly 300 participants from 26 countries already registered, ARC 2024 promises to be a hub for meaningful discussions about the future of recycling.

1 周Dissolution and depolymerization technologies represent transformative steps toward a genuinely circular plastics economy, where the value of polymers is not lost but continuously reintroduced into new cycles. By preserving polymer integrity or breaking them down to their core monomers, these methods unlock pathways for creating high-quality recycled plastics, reducing our dependency on virgin materials. The potential of these processes to handle complex, multi-material waste streams is critical, especially in a world that produces over 400 million tons of plastic annually. As these technologies scale, one question remains central: how can we accelerate investment, infrastructure, and policies to ensure that advanced recycling becomes a mainstream solution to global plastic waste?
