Tomra Sorting Recycling shared its knowledge of material recovery from electrical and electronic waste (WEEE) at the International Electronics Recycling Congress (IERC 2019), which was Jan. 16-18 in Salzburg, Austria. With legislation prohibiting the reuse of plastics containing brominated flame retardants (BFRs), the company discussed how combining its near-infrared (NIR) and X-ray technologies can enable the removal of up to 98 percent of BFR plastics from mixed plastic streams.
Judit Jansana, head of Tomra Sorting Iberia and part of the metal expert group at Tomra Sorting Recycling, said, “Now that plastics waste can no longer be shipped to China and simply forgotten about, there is growing demand from recyclers for
The company says its presentation noted that electrical and electronic devices contain from 3 to 60 percent plastic, approximately 30 percent of which contains flame retardants.
These fractions pass separately through the company’s X-Tract machine that features X-ray technology to separate BFR polymers from BFR-free polymers because flame-retardant elements have higher atomic densities that absorb more energy. This technology is independent of plastics input color, so black plastic is not an issue, according to the company.
“Separating BFR polymers from
