In today's world, plastic recycling has become a big problem. Many polymeric materials are not recycled nowadays because a low cost and efficient automated separation system has not yet been developed.

Use of markers to separate plastic in an automated and efficient way.

- simplicity of the process;

- low toxicity of the material used;

- high availability  of silicon in the earth's crust;

- possibility to separate black plastic.

On the occasion of the Italian Tech Week, the patented tecnology will be featured at the Tech Share Day to be held in Turin on June, 25, 2019, at the Polytechnic University of Turin.
