With the growing number of scrapped vehicles, the recycling of three-way catalytic converter cores has become an emerging green industry. The rare precious metals contained within them, such as platinum, palladium, and rhodium, have high recycling value. Each ton of scrapped cores can yield 300-800 grams of precious metals, with a recycling value exceeding 100,000 yuan.
MoreRecently, traffic police and environmental protection departments in many regions have jointly launched special crackdowns to crack down on the illegal disassembly and resale of three-way catalytic converters. Criminals target the precious metals contained in the cores, such as platinum, palladium, and rhodium, and commit crimes at night, causing direct exhaust emissions from vehicles and severely polluting the environment.
With the full implementation of the China VIb emission standard, automakers are increasing their investment in exhaust treatment systems. The three-way catalytic converter core, the core "purification heart," is undergoing an upgrade from a "universal" design to a "customizable, high-density, multi-layer coating."
MoreAgainst the backdrop of the "dual carbon" goals, my country's exhaust gas treatment technology has made significant progress. Recently, a Tianjin environmental protection technology company successfully developed a new generation of "high-activity coated three-way catalytic converter cores," which boast a 40% increase in precious metal utilization of platinum, palladium, and rhodium, enabling efficient conversion of harmful gases even during low-temperature startup.
