RE-SORT - Combatting the waste of plastic granulate
The new RE-SORT metal separation unit from Sesotec helps to improve efficiency in the circular economy
The plastics industry is faced with the challenge of producing
their products in a manner that is at once circular and highly efficient. Increasing
material efficiency is a crucial step towards achieving this goal. In addition
to its negative impact on the environment, loss of good material also means
productivity losses for plastics manufacturers and processors.
Initiatives such as ”Zero Pellet Loss” aim to prevent
the waste of plastic granulate. The project identifies three processing stages
where the majority of granulate loss occurs: unloading in the silo area, bag
and granulate container handling, and via conveying lines and equipment.
But many plastic granulates are also lost within
production itself. For example, metal
separators used to protect processing equipment detect and eject contaminated
material. This material must be disposed of, which means additional costs and
loss of value. All the while, analyses have shown that the rejected material
usually contains a considerable volume of good material in addition to metal
foreign bodies.
The new metal separation unit from Sesotec, RE-SORT
makes it possible to clean contaminated plastic granulate – regardless of the contamination source.
With magnetic and non-magnetic metal contaminants reliably removed, these
plastic materials can then be recovered for reentry into production.
The material is fed into the separation unit via a hopper. A vibrating
chute separates the material, which then passes through the EXTRACTOR magnet
system and the RAPID-VARIO FS metal separator. Thanks to a calibrated
combination of dosing, magnets, and metal separation, it is possible to recover
as much as 98% of the good material. The purified granulate can then be
processed further. This increases both the profitability and the environmental
friendliness of the entire operation.
