The 3D items that fall from the ballistic separator pass through a magnet system which reduces the risk of damage to the belts. This material then moves to a wood removal system where a closer pitch on the nozzle system ensures higher push power to eject wood.
Green Recycling has been particularly impressed with the ability of the AUTOSORT® technology to sort and recover plastics, as Jamie explains: “We always knew we had a lot of plastics in our infeed material, but we have never been able to fully quantify its volume and weight. Humans could never pick enough volume to warrant this material being recovered, and the speed at which the material passes through always made recovery difficult even with previous AI technology that we used. However, with the latest TOMRA equipment in place, we are now able to recover significant volumes of plastics at the high purity level required to meet industry demand. This has dramatically improved our facility’s overall recycling rates.”
The final stage in the process sees a fibre clean-up of any out of shape card, books and paper, of which there are large volumes in the plant’s infeed material. The way that two of the AUTOSORT® units have been positioned in the plant gives Green Recycling further scope to link them together and create a separate OCC and fibre grade in the future should they wish.
Jamie concludes: “We are recovering a far greater tonnage and a much wider range of materials than ever before. Our production line is no longer at the mercy of holiday schedules, absences or the continual challenge of searching for staff to undertake undesirable manual picking work. The investment in the new equipment has actually created two new skilled technical operator roles within the business to manage and maintain the TOMRA equipment. Now, even if we were to have several staff members off at the same time, our plant can continue running.
“The AUTOSORT® units have enabled us to future-proof our operations and ensure we are able to adapt to any future changes in C&I waste arisings. This is a hugely positive step for the business and one which will enable us to invest further in technology and staff development both now and in the future. Importantly, it has also helped us to close the loop on plastics recycling by keeping material in the chain.”
