In order to recycle secondary raw materials it is necessary to separate recovered materials that have been sorted either at source or at MRFs. The aim is to eliminate and residual contaminants to obtain an equivalent degree of purity to a raw material.
For a long while recyclers were at the forefront in their use of mechanical separation, and they were the first to incorporate optical separation technologies. For glass, these technologies have been used for over 15 years now, but it is a more recent development with plastics
Quality requirements for end-users are increasingly stringent irrespective of the type of material.
Since it was created Pellenc ST has been developing technologies to meet market needs and working closely with the recycling and refining industry on future developments. Pellenc ST has become the principal supplier for European PET recyclers and has installed machines around the world.
Current developments are in the recycling of paper and refining of glass, as well as the recovery and recycling industries in general.
