1. Failed Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs) can be recycled.
Many DPFs and DOCs carry a residual monetary value that can be converted to cash through recycling. Recycling failed DPFs/DOCs can also offset disposal costs while keeping the price of new catalyst parts down. While the monetary recycle value of DPFs vary, all DPFs can be recycled. Contact Red Fox if you’d like to find out what those fa
iled DPFs sitting on your shop floor may be worth.
2. It is not legal to resell used DPFs for reuse.
DPFs can not be moved from fleet to fleet. Plus, the reporting system (TRUCRS) would not accept a duplicate DPF serial number. Quoting item #13 from CARB’s FAQ Website on Heavy Duty Diesel Emission Controls Strategies:
A used filter installed from a vehicle not under the same common ownership or outside of a manufacturer’s approved swapping and re-designation policy, is a violation of California’s Anti-Tampering Law, Vehicle Code sections 27156 and 38391.
3. Failed DPFs should not be tossed in the garbage.
CARB has stated that the ash material that is removed from DPFs after the filter cleaning process is hazardous waste in California. While this statement does not necessarily mean failed DPFs are classified as hazardous waste, it can be concluded that the material contained in a used DPF has the same contents as the ash and has the potential to be a contaminate if land filled.
4. Not all OEM DPFs are required to be returned for core credit.
Many engine OEMs are tightening their DPF core acceptance policies for 2007 and DPFs and DOCs. Many dealers are finding the core credits coming back from the manufacturer are nominal. In many cases, a dealer may receive more value through recycling than through the core returns program.
5. In California it is not legal to replace a failed DPF with an aftermarket replacement unit not made by the OEM.
There are high-quality aftermarket replacement DPFs on the market in North America, however, as of April 21, 2016, these systems are not approved for sale in California. Fines have been issued to companies selling and installing aftermarket replacement DPFs before certification. You can follow the progress of this topic on CARBs Modified Part Procedure web page.
