This is what I found online regarding car recycling: There are indeed some environmental hazards that can come from any recycling process. After all, it does require energy and a factory to process these materials. However, this process is more eco-friendly than harvesting virgin metals. Instead of harming the earth through the processes of mining, we can reuse the materials already harvested.
