“…Plastics are currently produced on a global scale of more than 440 million tons annually 69 and account for 35.37 million tons (13.2%) of annual municipal waste in the United States, of which 26.82 million tons (75.83%) are landfilled. 70 Projections indicate that by mass, plastics will exceed fish in the ocean by 2050.…”

“…Current recycling methods are defined as primary, secondary, tertiary, and quaternary recycling. 69 Primary recycling is a closedloop mechanical process, whereby clean and pure feedstock may be melted, extruded, and remolded into a new product of the same type as that being recycled. Recycling of used polyethylene terephthalate (PET, also referred to as ''poly'') water bottles into new bottles is one example of primary recycling.…”

“…[54] There are many reviews that cover the pyrolysis, hydrocracking, and gasification of plastic waste with emphasis on the technique (i. e., operating conditions) and specific end product. [5,11,23,[27][28][29][30][31][32][33][34][35][36][37][38][39][41][42][43][44][45][46][47][48][49][50][51][52][54][55][56][57][58][59][60][61][62][63] Here, we present a comprehensive review of the various catalysts that have investigated for PSW conversion, focusing on the effects of catalyst properties on the outcome of the plastic conversion. This review aims to draw a connection between the impact of the textural properties of the catalyst and its performance for plastic conversion with hopes that this can be a useful resource for the development and design of future improved plastic waste conversion catalysts.…”

, 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.

Dedicated to Professor Klaus Muellen on the occasion of his 75th birthdayReversible-deactivation radical polymerizations (RDRPs) have revolutionized synthetic polymer chemistry. Nowadays, RDRPs facilitate design and preparation of materials with controlled architecture, composition, and functionality. Atom transfer radical polymerization (ATRP) has evolved beyond traditional polymer field, enabling synthesis of organic-inorganic hybrids, bioconjugates, advanced polymers for electronics, energy, and environmentally relevant polymeric materials for broad applications in various fields. This review focuses on the relation between ATRP technology and the 12 principles of green chemistry, which are paramount guidelines in sustainable research and implementation. The green features of ATRP are presented, discussing the environmental and/or health issues and the challenges that remain to be overcome. Key discoveries and recent developments in green ATRP are highlighted, while providing a perspective for future opportunities in this area.
