Upwash, a decontamination technology for mixed plastic wastes

TNO supported by Brightsite, has developed a type of hydrothermal processing, named UpWash, to upgrade difficult plastic mixture wastes. The most important stream of the UpWash process is a clean and densified form of polyolefin mix (PE+PP) virtually free of other plastics, inerts and biogenic contaminants, which facilitates the chemical or mechanical recycling processing.

Upwash, a decontamination technology for mixed plastic wastes

TNO supported by Brightsite, has developed a type of hydrothermal processing, named UpWash, to upgrade difficult plastic mixture wastes (e.g. DKR-310 and DKR-350), usually contaminated with waste food materials and paper / cardboard, metal, glass and sand / stones.

Advanced solvent-based technology for the closed-loop recycling of engineering plastics

Engineering plastics (e.g., ABS, PC and PMMA) have superior mechanical properties, such as strength and gloss. Therefore, they are primarily used in high-end products, such as electrical and electronic (E&E) devices and passenger cars. When it comes to end-of-life solutions, closed-loop recycling is often the only sustainable option for this group of plastics. This is mainly due to a lack of alternative product applications to absorb lower-grade recycled material in quantity. In turn, closed-loop recycling implies very high quality requirements on the recycled material to replace virgin resins.
