How do you extract platinum from a catalytic converter?
In many places, attempting to strip platinum from a catalytic converter is illegal and dangerous. The right path is to recycle through licensed facilities.
Catalytic converters contain precious metals—platinum, palladium, and rhodium—that can be recovered, but the process requires licensed facilities, specialized equipment, and strict environmental controls. This article explains why DIY extraction is risky and illegal in several jurisdictions, and how legitimate recycling works to recover metals while protecting people and the environment.
Understanding the platinum group in catalytic converters
Catalytic converters are engineered to reduce vehicle emissions and rely on a small amount of platinum group metals (PGMs) as catalysts. The exact mix and quantity vary by design and model year, but most modern converters contain a small, valuable amount spread across the substrate and washcoat. When recycled through proper channels, these metals are refined and sold to metal markets.
Platinum, palladium, and rhodium in modern converters
While each converter's content differs, the trio of platinum, palladium, and rhodium is commonly present, with the distribution evolving as automotive technology and emissions standards change. The value depends on market prices for PGMs and the efficiency of recovery in the refining process. Note that the vast majority of the value is realized through professional processing, not DIY extraction.

Legal and safety considerations
Trying to strip metals from catalytic converters on your own can be illegal and dangerous. Laws in many countries restrict the handling, dismantling, and processing of used automotive parts and require proper licensing, environmental controls, and waste management. DIY attempts can release toxic fumes and fine particulates, pose fire hazards, and create groundwater contamination. Penalties can include fines, vehicle impoundment, and criminal charges.
Responsible ways to handle used catalytic converters
The following options help ensure you stay within the law and support safe, environmentally responsible recovery of metals:
- Take the converter to a licensed metal recycler or a reputable scrap yard that handles catalytic converters.
- Prefer facilities that are certified for environmental responsibility and can provide proper documentation and receipts (chain of custody).
- Ask about how they process converters and what metals are recovered, along with their payment terms and timing.
- Be aware of any local requirements for handling hazardous materials and proper disposal of waste generated during the process.
Working with licensed recyclers ensures compliance with laws, minimizes environmental impact, and supports legitimate recovery of precious metals.
How legitimate recycling works (high-level)
Licensed recyclers and smelters carry out controlled, regulated refining to recover PGMs from used catalytic converters. The process involves sorting, preparing, and refining the material to extract platinum, palladium, and rhodium, which are then refined into marketable metals. The extraction is performed under strict safety, environmental, and product-control standards, and the resulting metals are sold to metal markets. This system protects users, workers, and the environment while ensuring metals reach legitimate supply chains.
Summary
Extracting platinum from catalytic converters is not a safe or lawful DIY activity. It carries legal penalties, health and environmental risks, and often yields little value without access to regulated facilities. The prudent path is to recycle through licensed recyclers or smelters, which securely recover precious metals and ensure compliance with laws and environmental protections.
