Up to 30% of the manufactured clothes hangers are made from recy- cled plastic Plásticos Ojara uses only polypropyl- ene (PP), polystyrene (PS), and polyeth- ylene (PE) to produce hangers. Around 250,000 kilograms of these materi- als are processed every day, most of which come from the company's own production. Waste generated in the production process (e.g. during start- up and shut-down) is shredded by the WLK 4, then granulated and returned to the manufacturing process to pro- duce new hangers. Around 30%of the clothes hangers are now made using regranulate. In addition to recycling in- house waste, the company also collects old clothes hangers from surrounding customers or stores. By creating an internal recycling line with WEIMA shredding technol- ogy, Plásticos Ojara has now become even more independent of external influences. Expensive raw material purchases are reduced to a minimum. This creates new scope for entrepre- neurial activity and further opportuni- ties to optimize production. Storage areas that were previously allocated become available again. Intralogis- tics expenses for waste handling are reduced. Thus, Plásticos Ojara is a Colombian flagship for the local recy - cling economy.
