What does hazardous waste processing involve?

Learn more about the process...


Understanding the negative environmental impact that transporting hazardous waste can pose if mishandled, Recognized Trading & Shipping takes all necessary steps to properly separate and store the waste according to all applicable laws and standards throughout the duration for which RTS and HongJing maintain custody of said waste.

Container Unloading

Once reaching HongJing's facility in Korea, their team efficiently works to safely offload the entirety of all units of hazardous waste that were properly sealed, loaded and shipped by RTS within industry approved shipping containers.


Once all units have been safely offloaded, the sealed units are housed along side similar kinds of waste, where they will be securely stored leading up to the beginning stages of HongJing's recycling and reprocessing.

Pre-Kiln Screening

The first step in the recycling and reprocessing stage involves properly screening the materials. This is done to remove particulates and any stray items HongJing wants to avoid placing into their rotary kilns, and typically includes deoiling and initial steps of decoking (see below).

Rotary Kiln Firing

The rotary kilns heat the material to a temperature range of 300-600° C in a process referred to as de-coking, which removes any potential moisture in preparation for crushing and grinding the substance to a fine powder. It is through this process that HongJing can later gain access to the metal alloys in the final stage of reprocessing.

Pollution Prevention

Heating the substances to such high temperature ranges often results in the creation of hazardous gases. An integral part of HongJing's process is contained within their pollution prevention facility which utilizes an intensive flue gas cleaning system to ensure the process continues to be environmentally friendly.

Production / Reprocessing

The final stage of the process ends with a leaching process that will allow extraction of much of the metal oxides the materials originally contained. This creates economical, and sustainable, benefits to HongJing that allows them to repurpose said materials (Mo, C, Ni, and Co) to flow back into industries like steel manufacturing, and allow others (Al) to flow back into production of ceramics and abrasives.
