Hamos GmbH of Penzberg, Germany, has developed a process to separate out rubber from seals, nylon and plasticized vinyl from vinyl windows, during recycling.
Normally, the company said, these items must be manually separated before shredding, a labor-intensive process. Using the Hamos system, window profiles are shredded into regrind, then dust is removed. Electrostatic separation equipment removes rubber and other contaminants.
Next, opto-electric color sorting equipment separates remaining rubber and color contamination from the material.
Hamos said the end-material vinyl has a purity of more than 99.995 percent.
