The invention is directed to a process for producing polyolefins by one or more homogeneous or colloidal polymerization catalyst wherein residual catalyst is removed by using a solid sorbent. The gathered paper is then pressed with a roller to crumple it, following which the crumpled paper is perforated along a serrated tear line. The software program may be executed on a processing system at a desired system speed and may be validated based on the execution.
