Approximately 95 percent of vehicles retired from U.S. roadways are recycled each year. The process begins with incoming vehicles being inventoried for parts. Then, recyclers start the engine to inspect for leaks. After inventory, fluids are drained and removed.

After all of the parts and products inside are removed, the remaining shell of the vehicle is crushed and recycled. How to Recycling a junk Car in MA
