Cinnamates as Greener Alternatives to Benzoates
Published on 2026-02-02 by Luke Froment, Jacqueline Lease, Prabu Satria Sejati, Firmin Obounou Akong, Christine Grardin Charbonnier, Yoshito Andou, Philippe Grardin @MDPI
Abstract: To address the environmental impact of petroleum-derived plastics, lignocellulose esters provide a promising renewable alternative. However, research has primarily focused on linear cellulose esters, leaving raw biomass aromatic derivatives largely overlooked. Herein, we report a one-pot, room-temperature synthesis of cinnamate and benzoate esters from microcrystalline cellulose (MCC) and raw pine sawdust. A breakthrough finding reveals that pine esters consistently outperform pure MCC, achievin[...]
Our summary: Cinnamates are identified as a greener alternative to benzoates in the production of sustainable materials. The study demonstrates a one-pot synthesis of cinnamate and benzoate esters from microcrystalline cellulose and pine sawdust.

Abstract: The rapid growth of personal protective equipment (PPE) consumption has generated unprecedented volumes of polymer-based waste, posing a major challenge to the transition from a linear to a circular economic model. The challenges associated with PPE recycling are strongly linked to the sector of origin—including healthcare, laboratories, cleanrooms, and food processing—as this factor determines contamination levels and critically influences subsequent recycling steps.[...]
Our summary: The increasing use of personal protective equipment (PPE) has led to significant polymer waste challenges. Effective recycling depends on source segregation, contamination levels, and tailored recycling technologies. Implementing appropriate strategies can transform PPE waste into valuable resources, supporting circular economy goals.
