Physical Recycling

Solvent-based processes, with plastics dissolved in solvents, enable the recycling of currently non-recyclable plastic compounds. With the LIST process, polyolefins can be recovered after selective dissolution of a polymer. The solvent is gently separated from a polymer solution, the polymer is recovered, and the solvent is condensed. A residual solvent content of less than 300 ppm is able to be achieved.

Our offer

Proven technology for separating solvents from solutions and viscous polymer melts
High product purity, high yields, continuous operation
Advanced process control:
- Uniform defined shear input for efficient and gentle separation of the solvent to protect the product
- Temperature control through evaporation cooling driven by mechanical dissipation and contact heat
- Homogeneous product temperature and concentrations due to excellent interfacial renewal and mixing
Fouling-free reactor design and trouble-free continuous discharge of the polymer
Safe evacuation of the vapors without product entrainment resulting in simple and stable process control
Extensive testing facilities in our test centers in Switzerland and Korea, for targeted process development
Industrialization experience for scales up to 10 t/h polymer solution
