From scrap to treasure

At METTOP, optimizing e-waste recycling operations is one of our core competencies—and we have once again demonstrated this through successful trials with one of our customers, a leading recycler of e-waste and precious metals.

Our Managing Director Dr. Andreas Filzwieser and Business Developer Dr. Christoph Sagadin provide on-site support at the recycling facilities to enhance the processes for recovering copper and precious metals. By addressing challenges in a targeted manner, we achieved:

• significant increases in recovery rates for copper and precious metals,
• a notable reduction in energy consumption, and
• sustainably increase of production capacity.

How We Achieved These Results

At METTOP, we start by analyzing the composition of the raw materials in order to optimally adjust furnace process parameters. Based on the present impurities and production targets, we recommend the most effective slag formers and additives. Every step of the process—from charging and furnace settings to slag formation and casting processes—has been reviewed and adjusted to eliminate inefficiencies and achieve excellence.

Here is why METTOP is your ideal partner for recycling PCBs and metal-containing residues:

• Excellent metal recovery: recovery rates more than 98.5% allow a high yield of copper and precious metals such as Au, Ag and PGMs.
• Energy-efficient processes: Optimized charging sequences reduce melting time and lower energy consumption.
• Slag compositions: Low-viscosity slags improve metal recovery, enable lower operating temperatures while minimizing energy consumption.
• Optimized process flows: Tailored solutions for each phase—from reducing energy consumption to melting, converting, and refining processes for maximum efficiency.
• Advanced sampling and automation: Precise quality assurance minimizes waste and enhances reliability.
• Recovery of by-products: Efficient recovery of valuable by-products such as Sn, Ni, Pb and other important elements for additional added value.

With METTOP's expertise, your e-waste recycling will become more efficient, sustainable and profitable—making it fit for the future.
