Preparing DPF/DOC shipments for recycling

How To Package DPFs and DOCs for Shipping [Video]

on August 23, 2017

We often use common customer questions as a yardstick for good topics that should be shared on our Red Fox Resources blog. For example, a very common question is, “how do we prepare shipments of DPFs and DOCs to be shipped to and recycled by Red Fox Resources?” It’s actually pretty straight forward, with the following requirements and a video overview:

The shipment must be palletized so it can be moved by forklift.
All the items must be secured on the pallet with shrink wrap or a wood/cardboard enclosure as shown in video.
Red Fox pays shipping costs only when you have a minimum of 5 DPFs/DOCs per shipment.

DPF Ash Disposal – What You Should Know

on July 20, 2017

As DPF (diesel particulate filter) cleaning becomes a routine part of truck maintenance, the proper disposal of recovered DPF ash is a common question for shops and fleets. Unfortunately, depending on where your located this can be a complex topic. We’ll attempt to provide some clarity on DPF ash disposal in this article by starting with the basics.

This blog post is intended to be a general guidance on DPF ash disposal. You should consult your local and state environmental regulatory agencies for accurate regulations regarding hazardous waste determination and disposal in your area.

How is DPF ash generated?

A DPF physically traps and collects diesel soot from engine exhaust. While the trapped soot is burned off during periodic filter regeneration, metal oxide “ash” particles are not burned off. Over time, the unburned ash particles will plug the filter unless the filter is periodically cleaned.

Red Fox Featured in July’s Issue of Fleet Maintenance Magazine

on July 14, 2017

Red Fox was proud to contribute to the July 2017 “Reman, Rebuild, Replace” column in Fleet Maintenance Magazine. The article succinctly covers the virtues of DPF/DOC recycling. See the full copy below or link to the article in the July 2017 Fleet Maintenance Magazine.

From July 2017 Issue of Fleet Maintenance

As part of the ratcheted-down emissions regulations finalized in 2001 for on-highway diesel engines, the U.S. EPA set standards – to be implemented in 2007 – requiring that particulate matter (PM) emissions be reduced by 90 percent. To achieve this, engine OEMs developed engines that would operate with higher efficiency and lower emissions.

The engines were equipped with exhaust aftertreatment devices that included diesel particulate filters (DPFs) and a diesel oxidation catalyst (DOC) system, and required the use of ultra low sulfur diesel (ULSD) and low-ash oils.

Red Fox Partners with Hino Trucks

on September 1, 2016

Oakland, CA, September 1, 2016 – This program allows dealers of Hino Trucks to recycle spent emission cores, such as diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs), that either fail OEM core acceptance criteria or do not carry a core value. Red Fox Resources purchases the spent emission control systems from the dealer and reclaims the catalyst material for re-use.

What CARB’s Passing of the Aftermarket DPF Approval Program Means for Fleets

on August 22, 2016

Today the California Air Resources Board (CARB) heard and unanimously passed staff’s recommendations on amendments to the Aftermarket Diesel Particulate Filter Approval Regulation (note Chair Nichols abstained from the vote citing she did not hear the entire staff presentation). It is important to understand this hearing and approval process only applies to aftermarket diesel particulate filters (DPFs) in California. These parts are currently being legally sold and successfully deployed in every other state in the country.

3 Reasons Why DPF and DOC Recycling is Good for Business

on May 10, 2016

A Quick History – DPF and DOC Recycling:

Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs) have been a reality for fleets and diesel service shops around the US since 2007. In 2007 the EPA ratcheted down the emission standards for particulate matter (PM) from diesel engines by 90% from the 2002 standards. As a result of the implementation of the 2007 standard, engine OEMs were then required to include DPFs in their standard engine package as DPFs are able to achieve the emission reductions needed to meet the standard. DPFs have been a standard component in diesel engines since 2007.

5 Things California Shops Should Know About Failed Diesel Particulate Filters

on April 21, 2016

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.
