We mainly target difficult plastics. Mechanical recycling process, although very efficient for transparent PET bottles, shows some limitations. We listened with great attention to the issues encountered by renowned recyclers and worked closely with them. It turns out that the two types of PET plastics which may presently pose real problems for mechanical processes are food trays and colored plastics. These are not compatible with sorting processes and disrupt the production of recycled PET pellets. We have therefore optimized our process around these two families in order to be able to supply the different ranges of starting monomer bricks and to be able to remanufacture virgin food grade PET. We transform unsorted waste into a product with high added value. We continue challenging our process with all sorts of complex, multilayer and composite plastics with encouraging results.
