Diesel Guys learning about scrapping

Hi all - myself and 3 of my business partners are veterans of the diesel world as we worked for Cummins for many years. Living in California - we got the entrepreneurial itch about two years ago and started collecting and recycling emission control parts (catalysts and filters) from diesel engines in the area. Its been a challenge to say the least and we've learned a lot and have scratched out enough to grow our business little by little. We know we have a TON to learn about the scrapping & recycling industry, which is why we're here!

Can't wait to dig into the archives to start researching about the industry and participating actively where it makes sense.

Shoot us any questions about diesel parts you may have - we're always looking to share!

What are dpf filters made out of?

typically Silicon Carbide or Cordierite but there were retrofit systems that used sintered metal.

Thanks.
