“The idea is to make everything easier,” says Rabnawaz, an assistant professor in the College of Agriculture and Natural Resources. “If we can do that, we can stop thinking of plastic as a waste or a burden. We can treat it as a resource.”

Mechanical Recycling of a Bottle-Grade and Thermoform-Grade PET Mixture Enabled by Glycidol-Free Chain Extenders
Industrial & Engineering Chemistry Research2024 The accumulation of plastics in landfills and oceans poses a significant environmental threat, and this issue has led to a strong push for more and more plastic recycling. Recycled polyesters such as poly(ethylene terephthalate) (PET) have inferior performance in comparison with their virgin counterparts. This performance can be restored by employing chain extenders (CEs), but they are often glycidol-based and present health concerns. Reported herein is a novel approach to valorizing bottle-grade PET (PET-B) and thermoform-grade PET (PET-T) waste by developing a novel glycidol-free hindered epoxy as a CE to enhance the mechanical and thermal characteristics of PET-B + PET-T blends.
Design of Carboxylic Acid‐Functionalized Poly(Butylene Adipate‐co‐Terephthalate) for Recyclable and Biodegradable Zero‐Waste Paper Packaging
Advanced Sustainable Systems2024 Demand for water‐ and oil‐repellent‐coated paper as an alternative to plastics is growing, but the challenge is that coated paper lacks concurrent recyclability and biodegradability. Reported herein is a novel carboxylic acid‐functionalized poly(butylene adipate‐co‐terephthalate) (CPBAT) copolymer investigated for recyclable and repulpable water‐borne paper coatings. The CPBAT synthesized here is characterized by spectroscopic methods. Paper coated with waterborne CPBAT exhibited excellent water, oil, moisture, and gas barrier properties suitable for packaging applications. The recyclability and repulpability of the CPBAT‐coated paper are successfully validated via certified TAPPI methods.
One-pot synthesis of robust silyl ether-based HDPE vitrimers with enhanced performance and recyclability
Polymer2024 Vitrimers are thermally reversible crosslinked polymers that combine the performance of thermosets with the benefits of melt (re)processing. However, existing high-storage modulus vitrimers lack this melt-reprocessibility. This study reports on high storage modulus vitrimers obtained by grafting vinyltrimethoxysilane onto high-density polyethylene (HDPE) using silyl ether crosslinker, bis[3-(trimethoxysilyl)propyl]amine. We also explored the effects of 2,2,6,6-tetramethyl-4-piperidinol and diethyl maleate on the performance of these vitrimers. All vitrimers reported herein are prepared in one step via melt-extrusion without the use of any solvent or catalyst.
Tailoring Olefin Contents Formation during Waste Plastic Pyrolysis
ACS Applied Polymer Materials2024 As reported herein, we investigated the effect of feedstock composition, reactor type, and catalyst on the olefinic composition of oil recovered through plastic pyrolysis. We investigated an open reactor versus an autoclave closed reactor using polypropylene, linear low-density polyethylene, high-density polyethylene (HDPE), and low-density polyethylene, including both virgin and waste mixed plastics as feedstocks. The obtained oils were analyzed for comparison to their olefin contents.
Technoeconomic Analysis for Biodegradable and Recyclable Paper Coated with Synthetic Ionic PBAT for Packaging Application
ACS Sustainable Chemistry & Engineering2024 This study presents a technoeconomic analysis (TEA) for a novel ionic polybutylene adipate-co-terephthalate (PBAT), CPBAT, as a paper coating material, showcasing excellent water and oil resistance. This TEA determined total capital investment, operating costs, and minimum selling prices for a production capacity of 1,000 kg of CPBAT per day. The minimum selling prices of CPBAT coated on Kraft paper (CPBAT-K) and CPABT coated on starch-coated Kraft paper (CPBAT-S) are estimated to be $1.327/m2 and $1.864/m2, respectively.
