Two AUTOSORT®'s [NIR1] units were installed, with a working width of 1,400mm, using dual-track technology. The PET fraction is separated in the first track of the first unit, while the remaining materials go on to the first track of the second TOMRA unit for the separation of HDPE. The reject from the first track of this second unit is redirected by conveyor belts to the second track of the first separator
The second track separates board from drinks containers, while the remaining material is sent to the second track of the second unit, where the final automatic separation is carried out to remove the mixed plastics fraction. In this way, four fractions are separated with optimum efficiency and purity using just two TOMRA units.
The third unit is a AUTOSORT® with a width of 1,000mm. It is positioned in the flat fraction line for the separation of paper and board before the waste stream enters the plastic film separator. The fraction of film thereby suctioned off is of high quality while the process additionally generates a fraction of recovered paper and board.
Greater productivity and better working conditions with AUTOSORT 4
One of the AUTOSORT® 4 units, with a 2,000-mm operating width, is set to separate paper and card, while the other, with a 1,400-mm operating width, has been configured as a double track for sorting PET and HDPE. This incorporation enables the plant’s recovery processes to be optimized, so that in the case of paper and card, total recovery has increased by over 2%, while for recovery of waste in general, improvement has risen from 3% formerly, to 6%, or 70,000 tons per year.
The AUTOSORT® 4’s advanced technical features have provided clear benefits in terms of productivity, but also insofar as work processes in the plant. In the view of Jesús Sánchez Vela, the plant foreman, “the main advantage is the increase in recovery, with the environmental benefits this signifies. Yet the quality of the work of staff at the plant has also improved. They focus their efforts above all on monitoring the quality of the materials selected and overseeing the units. Furthermore, we can easily configure the sorting of sub-products, for which configuration of the plant according to operating requirements is helpful”.
Easy maintenance and energy savings
The AUTOSORT® 4 needs less maintenance than the previous model, being easier to clean and using less power. The new concept of a valve block translates into greater accuracy and speed, while our FLYING BEAM® technology allows electricity savings of up to 70% by incorporating the lighting module inside the scanner itself. Furthermore, the unit’s compact streamlined design reduces maintenance to a minimum, with the ensuing savings in inactivity time and employee hours.
