Metallix Refining, a leader in precious metal recycling, announced the launch of its latest innovation: APR4 – Advanced Pyrolytic Reduction. Building on the proven success of the APR3 furnace, APR4 marks a significant leap forward in engineering, sustainability and operational excellence.
Developed by Metallix’s expert processing engineers and technical specialists, APR3 and APR4 represent the next generation of the company’s proprietary Advanced Pyrolytic Reduction technology. These systems feature two oxygen starved, continuously fed furnaces that thermally decompose materials in a controlled environment using indirect heat, enabling the safe and efficient processing of organic materials while minimizing environmental impact.
With enhanced processing controls and a revolutionary air pollution control system, APR4 sets a new benchmark in precision and environmental responsibility for precious metal recovery.
“At Metallix, innovation is our driving force,” said Maria Piastre, chief executive officer of Metallix Refining. “The APR4 is designed to process an unprecedented range of precious metal-bearing materials – gold, silver, platinum, palladium, rhodium, and iridium – from even the most complex and challenging waste streams. APR3 and APR4 are purpose-built innovations designed for the future of recycling.”
As with all Metallix systems, APR4 is engineered around the company’s core pillars of sustainability, safety, and value recovery. Featuring advanced automation, APR4 reduces the need for manual intervention, minimizing exposure to hazardous materials and enhancing operational safety. Proprietary sensors and real-time data analytics enable continuous performance monitoring and optimization – improving energy efficiency, reducing emissions, and supporting Metallix’s commitment to a circular, sustainable economy.
