We specialize in purchasing used catalysts and particulate filters. For the appraisal, we analyze the precious metal content of the ceramic material block and, after its valuation and purchase, we take care of all the necessary procedures to proceed with its recycling.

The evaluation of the catalyst, batch of catalysts or particle filter, is carried out both in person in our facilities, via WhatsApp or by email, consulting the references of each of them. Catalyst ceramics are analyzed with a mass spectrometer to quantify the precious metal content of each block. The immediate payment of materials is guaranteed provided that the regulations on cash payments are complied with.

Catalysts or catalytic converters are basic components in internal combustion engines (both petrol and diesel), and serve to control and reduce emissions of harmful gases resulting from such combustion. Catalysts are therefore key to reducing the environmental problems posed by air pollution.

At the end of their useful life they must be recovered: extracting and recycling the precious metals that make up the ceramic block favors the circular economy, decreasing the use of virgin raw materials in the manufacture of the new catalysts.

As professionals responsible for the environment, we always advise to keep car catalysts in good condition, repair or replace them when necessary and ensure that parts are recycled correctly and with all guarantees.
