Exhausts clean out toxic gases coming from internal combustion engines with catalytic converters. Catalytic converters are produced resistant to high temperatures. However, gases with high carbon emission block the honeycomb ceramic structure inside the catalytic converter after a certain period of time and should be replaced. A catalytic converter that has been dismantled and turned into waste is at least as valuable as the new one. Because it contains platinum, pladium and rhodium. Their value is increasing rapidly today.
It is possible to sell the internal material after the honeycomb structure is removed in the recycling of catalytic converter. In addition, this powder can be easily enriched with easy-to-install and affordable systems. The primary unit for that is the ball mill. You can grind the material in micron sizes in the ball mill. Ball mill can be selected according to the capacity of your material and your budget.
