If we can have laws that bring strict liability for financial institutions who don't know their customers (KYC) for anti-money laundering (AML) purposes, we can bring in laws requiring scrapyards to know their customers for anti-trafficking in stolen property purposes. Catalytic converters, like many auto parts, have serial numbers on them. Tracking these should be standard practice for scrapyards. Furthermore, scrapyards should be subject to random surprise inspections to enforce this. Furthermore, the palladium in catalytic converters should be doped with traceable radioactive isotopes and an enforcement scheme put in place to catch unscrupulous smelters who melt down the catalytic converters and attempt to sell the metal on the open market.
