Ceramic catalysts

The ceramic body of a catalyst (monolith) honeycomb contains thinly walled channels, coated typically with platinum, palladium, and rhodium which provide the catalytic effect in the exhaust gas stream.

Whether whole ceramic converters, semi-crushed monolith, or ground monolith – high-precision processing is standard at MAIREC.

Metal foil catalysts

The precious metals carrier of metal foil catalysts consists of a thin, corrugated, tightly wound metal foil. Recycling these catalysts is difficult and costly.

MAIREC has developed its own highly efficient technology to guarantee the best results on the market.

Diesel particle filters

Diesel particle filters, also known as DPFs, reduce the amount of harmful particles in the exhaust gas of diesel engines. The porous walls consist mostly of silicon carbide (SiC) and also contain precious metals.

Oxygen sensors

An oxygen sensor is a sensor that measures the oxygen content in the exhaust gas flow of a car, enabling the engine control system to regulate the correct fuel-air mixture.

MAIREC has developed a particularly innovative recycling solution for end-of-life oxygen sensors.

Highly effective, proprietary technology

At MAIREC you benefit from the highest standards and meticulous precision in separation, homogenizing, sampling, and value determination. In addition to the modern and highly effective solution for your ceramic materials, our efficient unique proprietary separation technology in the field of metal foil catalysts and oxygen sensors guarantees the best results on the market.
