" This is particularly true for aluminium and copper grains, an area in which MTB has become the market reference. "

By means of its laboratory analysis, MTB is able to supply a precise analysis certificate for each batch processed.  In this way, the characteristics can be supplied for the products put on sale. In our search for excellence, these analyses also allow us to measure the benefit of our innovations on the quality of our products.

Thus, the grains are classified by quality, with references going for Copper from GRCU1 (99.99%) to GRCU6 (96%) and for Aluminum GRAL1 (99.7%) and GRAL2 (99.5%).

Apart from Aluminum and Copper grains, MTB is able to diversify and recycle many other products. Plastics, for example, have become a priority and we are able to offer products without metallic residues and a purity which can be greater than 99%. PVC, PE, ABS-PS and PE-PP are now, no longer wastes, they are raw materials!
