Upon request, we will invest into appropriate processing machinery, whereby the amortization term will be defined by the additional profit.

Normally the extracted material will be market here within direct sales contracts.

Explanation of the Process Example

This is how Renkaede takes an example process into the last step.

You produce structural components made of aluminum for tier-1 OEM’s for the automotive industry and require hot-rolled products as pre-materials, which are stamped and formed during hydroforming process.

The collection and processing of your sheet metal scrap will be optimized directly at your production plant, by investing into appropriate scrap baling machinery, which processes the sorted scrap into packages. The packages can now easily be loaded up to the truck and delivered to the remelting furnace.

Arrived and uploaded at the remelting furnace, raw material will be extracted by remelting the scraps and adding low percentage of primary aluminium, in order to cast the extracted aluminium into “slabs”.

Renkaede supplies these to its partners for tolling, where slabs are tolled to hot-rolled products, before these will be provided again as your pre-material.
The return journey is again used to deliver your sorted and processed scraps to the corresponding remelting furnace.
