RECYCLING FOR MORE QUALITY RAW MATERIAL!

In the company STARA VAROŠ d.o.o., quality processing ensures secondary raw material used as the material applied in:

Ironworks

A wide range of materials
A bit bigger parts

Foundries

The Material is cut into smaller parts and classified according to the type

The application of processed material depends on the additives used for the refinement of steel.

Every customer purchasing our material can request additional information on the material composition.

The first step in purchasing and recycling procedure is a harmonization of quantities and price with a vendor and afterwards there is a technological process including the phases as follows:

Loading of material

By our own means

Distributing the material

To our centers

Measuring

On a weighbridge

Radiology check

Of supplied material

Reception

Unloading

Classification

Material treatment

Using Schredder mill, a press, scissors and oxy-fuel cutting
