During the time of TowerBrook’s Fund III investment, Metallo was a European refiner and recycler of secondary metals, principally copper and tin. The company leveraged its technology and knowhow to add value to low-grade, non-ferrous materials sourced globally.  Over 350,000 tons of raw materials were recycled annually through the different stages of Metallo’s recycling processes and returned back into the value chain with zero waste. TowerBrook exited its investment in 2020 via a sale of Metallo to Aurubis AG.
