264792 - Beneficial reuse of PCBs (poly-chlorinated biphenyls) as new materials

Tuesday, June 6
4:00 PM - 4:20 PM

Thermal desorption or thermal oxidation has been demonstrated as one of the effective ways to treat PCB contaminated oils, soils and sediments. However, the goal at that time was to completely oxidize the organic waste instead of material recovery. While effective, the cost tend high, ranging from $200 to $1,300/ton, partially due to the high temperature used. Today, as resources become increasingly limited, material and energy recovery should also be considered in waste remediation, which can also offset the cost of treatment.
With PCB compounds, de-chlorination is the first and most important step in reuse, which also reduces toxicity. Much lower temperatures are desirable in order to avoid metal evaporation and to reduce the cost. The paper will present the effectiveness of catalytic de-coloration of PCBs at low temperatures using catalysts under hydrogen environment. The catalyst responsible for dechlorination is palladium on carbon and triethylamine (Pd/C and Et3N). Then the temperature will be increased to convert the biphenyl into other more useful and less toxic chemicals, such as cyclohexyl benzene and bicyclohexyl. The catalyst responsible for biphenyl hydrogenation is platinum (Pt). Results will be presented on PCBs with 1, 2, and 3 chlorines to better understand the process for chlorine removal, and new product formation.

She has been a long term AWMA member since 2004. has been an active AWMA member since 2004, and has been very supportive of various AWMA activities. Over the years, her students have won various prestigious awards from AWMA, such as the best MS thesis award (Rachel Agnew), and the Jacqueline Shields Memorial Scholarship in recognition of excellence in waste management (Drs. Ming Chai and Qingshi Tu). She became the faculty advisor of the award winning UC student chapter in May 2015.

In 1997, she became a member of the Editorial Advisory Committee (EAC), which oversees the EM publication. She has championed 7 special issues of EM, served as vice chair of EAC and then Chair (2013‐2016). She currently also serves as vice chair of the Professional Development Division of the Ed Council.
