Denua™️ technology - PET Recycling without compromise
Ioniqa Technologies Article, published in #connectingcomPETence, issue TWO:24, July 2024
#Denua™️ technology was developed by Ioniqa Technologies in partnership with Koch Technology Solutions to enable recycling of most post-consumer PET waste, especially the feedstock that mechanical recycling processes cannot treat such as sorter rejects, fines, and mixed coloured flakes.
The heart of the technology is a #glycolysis process, in which PET is depolymerised to bis(2-hydroxyethyl) terephthalate (BHET) with the help of a magnetic catalyst, which is, due to its properties, easily recoverable after the reaction. After the glycolysis reaction has been completed, BHET is further purified to remove other reaction byproducts as well as contaminants which might be present in the waste plastic feedstock. BHET is a monomer known in the PET industry, as it is an intermediate in today’s PET polymerisation processes. Denua™️ technology can be therefore easily integrated into an existing PET facility to take advantage of the infrastructure including utilities, logistics, and fundamental maintenance and operations capabilities.
