PET-Recycling with watermarks

By adding a 3D-Watermark to plastics, mostly PET-bottles and trays, FiliGrade provides waste sorting companies a unique method for selecting.

When reading the nearly invisible watermark is exactly known what type of plastic the product is, so an optimal selection can be done. And different to chemical methods: no residu remains so the plastic can be optimal recycled! 

Nearly invisible for the human eye, but readable by a (mobile) camera, in infrared, daylight, ultraviolet 

The watermark is covering the full product so dirt and distortions have no influence on the readability

FiliGrade patented technology makes a circular economy achievable.

Februari 2018, FiliGrade tested successfully their solution for reading watermarks on IML-tubs and transparent PET-bottels at a speed of 2 meter per second on a waste belt, next step is improving reading speed. The principle of the selection method with watermarks, printed or embedded is now approved as fully functional.

An example of reading a PET-tray with a smartphone as a consumer could do to find out if the tray should end in the plastic disposal bin or in the rest disposal bin for proper recycling.
