Van Dyk Recycling Solutions (VDRS), Stamford, Connecticut, is telling WasteExpo 2018 attendees about its latest strategies to combat China’s trade restrictions at its booth during the annual event in Las Vegas April 24-26.
Positive sorting is the use of Van Dyk’s optical sorters to target paper materials and eject them from the stream. Removing paper from the prohibitives, rather than the other way around, can allow the paper to stay clean and avoid collateral damage, VDRS says.
New developments in laser technology allow Van Dyk’s opticals to recognize every object on the belt, according to the company, including film, glass, organics, black plastics, black objects and random trash items. The result is a cleaner paper grade capable of passing China’s 0.5 percent restriction.
Recent plants to adopt this concept include Sanco, Escondido, California; Phoenix-based Republic Services’s Plano, Texas, plant; and Houston-based FCC Environmental’s Houston plant.
Van Dyk is exhibiting at WasteExpo at Booth No. 3417. For more information, visit vdrs.com/positive-sorting.
