URT PLANT ENGINEERING SUCCESSFUL IN BATTERY RECYCLING
The first plant for recycling end of life e-car batteries from an automobile manufacturer started operations
at the beginning of 2021.
„Our goal is to create our own cycle with more than 90 percent recycling of our batteries,“ says Thomas Tiedje, Head of Technical Planning at Volkswagen Component. „We don‘t want to hand over the process at any point, but prefer to qualify our own employees and thus make them fit for the future.“
The special feature: only batteries that really can no longer be used in any other way are recycled.
Before that, the modules built into the battery system are checked to see if they are still in good condition and can possibly be given a second life in mobile energy storage systems such as flexible fast charging columns or charging robots.
This significantly extends the useful life of the modules.
This innovative plant was designed, built and delivered turnkey by the Bavarian plant manufacturer URT Umwelt- und Recyclingtechnik GmbH (URT) from Karlstadt am Main.
For more than 25 years, URT has been involved in the construction of processing plants for electrical and
electronic waste and supplies them worldwide.
It is precisely this knowledge that can be incorporated into the processing plants for batteries, because URT is, for example, a specialist in shredding in inert atmospheres to prevent exothermic reactions, which can also occur during battery shredding.
The aim of the plant is to separate the materials of a lithium-ion battery as well as possible so that each recyclable material can be used again in a new battery.
URT PLANT CONCEPT
The previously deep-discharged batteries are fed into a single-stage shredding process via a sluice system.
Subsequently, the shredded total fraction enters a vacuum dryer, which evaporates the electrolytes, which are then condensed again and filled in liquid form.
This process section, from shredding to dryer discharge, is encapsulated and kept inert by a nitrogen atmosphere.
The dry active material (black mass) is separated from the remaining components by sieving and filled.
In order to meet the European recycling targets, the active mass must be almost completely separated.
Ferrous metals are separated from non-ferrous metals by magnetic separation processes. Anode and cathode foils are further components of the batteries that are separated in the plant. In addition to falling below the occupational exposure limits, the emission values are also below the TA Luft (Technical Instructions on Air Quality Control). This is ensured by a multi-stage exhaust air after-treatment system consisting of gas scrubbing and activated carbon adsorption.
Plant concepts with exhaust air post-combustion are also conceivable.
