Maximising the benefits of the sorting operation
Jinlijia’s upgraded non-ferrous metal sorting line contains four eddy-current sorters and one TOMRA FINDER, with the objective of fully recovering the non-ferrous metal from the mixed scrap. With this new line, over the course of 12 months Jinlijia was able to make approximately RMB1.5 - 2 million in additional profit.
As well, if the FINDER is able to separate pure stainless steel from the non-ferrous mix, this eliminates the need for four manual pickers, saving Jinlijia an additional RMB200,000, within a 12-month timeframe. More importantly, the previous, manually-operated line was inefficient and lost not only insulated wire but also, following eddy-current separation, amounts of small-size stainless steel, along with copper (including uninsulated wire), aluminium, and some PCB material. But with the new, upgraded line, all of these materials can be recovered by the TOMRA FINDER, and both the recovery rate and operational efficiency have been significantly enhanced.
“The recovery rate and product purity were both enhanced tremendously after the installation of the TOMRA FINDER in our sorting line, making our operation much more profitable than before. The system effectively eliminated manual sorting in downstream processes and significantly enhanced profitability by generating purer end-fractions that then drove added value," said General Manager Peng Haili, as he summarised, in a very complimentary way, the value of the TOMRA FINDER.
TOMRA extracts more value from waste by continuously improving its sorting solutions
Currently, after the waste has been finally sorted by the FINDER, the remaining waste contains mainly non-metallic materials, such as plastics, foam, wood and rubber. These materials are no longer suitable for further sorting and recycling, in terms of value, according to JInlijia. However, TOMRA is still in communication with Jinlijia, with a view to the possible further recycling of the remaining waste, to make the best use of these resources. TOMRA is committed to finding a viable technical solution, one with sufficient return on investment.
In addition, TOMRA is in discussion with Jinlijia on the extraction of pure copper, aluminium and zinc from the currently sorted Zorba, in order to sell it separately on the market, thus further increasing the value of the materials and the prices of the end-products. If the purity of each metal can be significantly enhanced, they can be sold at almost the same price as the original material. By doing so, not only would operational efficiency be enhanced, Jinlijia could also achieve sustainable development, both for its own business and for the environment.
