“…Natural zeolites were found to have moderate cracking ability with higher selectivity towards the liquid fraction, but its efficiency was strongly correlated to the plastic/catalyst ratio. 412,[450][451][452][453][454][455][456][457][458][459][460] Given the uncontrolled structure of natural zeolites, the materials contain impurities and there is little consistency amongst the materials. As such, there is high variability in the effectiveness of natural zeolites.…”

Less than 10% of the plastics generated globally are recycled, while the rest are incinerated, accumulated in landfills, or leach into the environment. New technologies are emerging to chemically recycle waste plastics that are receiving tremendous interest from academia and industry. Chemists and chemical engineers need to understand the fundamentals of these technologies to design improved systems for chemical recycling and upcycling of waste plastics. In this paper, we review the entire life cycle of plastics and options for the management of plastic waste to address barriers to industrial chemical recycling and further provide perceptions on possible opportunities with such materials. Knowledge and insights to enhance plastic recycling beyond its current scale are provided. Outstanding research problems and where researchers in the field should focus their efforts in the future are also discussed.

“…Naturally occurring silica‐rich zeolites, such as clinoptilolite and mordenite, are studied as potential catalyst materials because they are readily available and inexpensive [99] . Natural zeolites in the protonated form have been used for PP, HDPE, LDPE, PS, PP/HDPE, EVA, and PET degradations and have shown moderate cracking ability and improved yields of liquid product, while also increasing char production [98,99,107,111,112,182–194] . However, catalyst efficiency has been strongly correlated to p/c ratio [191,192] .…”

, respectively. Her graduate research focused on the fundamental understanding of deoxygenation mechanisms for biomass probe molecules on single crystals and thin films. During her graduate career, she received the DOE Science Graduate Student Research (SCGSR) award (2019) and conducted surface science research at Brookhaven National Lab. She now is a postdoctoral researcher at the University of Wisconsin-Madison. Her research focuses on surface spectroscopy and controlled design of heterogeneous catalysts. Melissa C. Cendejas received her B.A. (2016) in Chemistry and English from Williams College. There, she worked on the synthesis of conjugated organic molecules and phosphorusbased surfactants. She then started her PhD in Chemistry at the University of Wisconsin-Madison under the supervision of Prof. Ive Hermans. She studies active site formation on boron-based catalysts. She received the DOE Office of Science Graduate Student Research (SCGSR) award (2020) to perfrom in situ x-ray spectroscopy of catalysts at Stanford Synchrotron Radiation Lightsourse. Prof. Dr. Ive Hermans obtained his Ph.D. from KU Leuven University in Belgium in 2006. In addition to his scientific education, he also holds a postgraduate degree in Business Administration (KU Leuven, 2006). After postdoctoral research on in situ spectroscopy and reaction engineering with Prof. Alfons Baiker, he became assistant professor for heterogeneous catalysis (spring 2008) at ETH Zurich in Switzerland. January 2014, Prof. Hermans moved to the University of Wisconsin-Madison, holding a dual appointment in the Department of Chemistry and the Department of Chemical and Biological Engineering. His group focuses on the mechanistic understanding of catalytic technology using a variety of techniques.
