<p>By according to the invention to use a method to recycling of rigid PVC, can the problems by removal of this waste be met. The method is that rigid PVC divides to chips (14) and is mixed with new PVC-resin (12), to which there is added a certain number of plasticizers (13), which mixture is compressed and melted until it is extruded through a tool (7, 8) and pelletized (9). Thereby this method produced material (15) can be used to production of new products, as it has physical properties corresponding to new PVC and furthermore can have greater softness.</p> |
