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. Pine esters exhibit superior mechanical properties and hydrophobicity, supporting their use in eco-friendly packaging solutions.

Collection, Polymer Recovery, and Circular Pathways for Post-Consumer PPE
Published on 2026-01-27 by Giulia Infurna, Marinella Levi, Loredana Incarnato, Nadka Tz. Dintcheva @MDPI
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.

Technoeconomic and Life Cycle Analysis of a Novel Catalyzed Process for Producing Ethylene from Waste Plastic
Published on 2026-01-17 by Xiaoyan Wang, Md. Emdadul Haque, Chunlin Luo, Jianli Hu, Srinivas Palanki @MDPI
Abstract: Polyethylene is the most used plastic in the world, and over 90% of this plastic is ultimately disposed of in landfills or released into the environment, leading to severe ecological implications. In this research, the technoeconomic feasibility of upcycling low-density polyethylene (LDPE) to produce ethylene is studied. The catalytic conversion of LDPE to ethylene is considered in microwave heating mode and Joule heating mode. Experimental data is obtained under conditions where most of the upc[...]
Our summary: This research evaluates the feasibility of converting low-density polyethylene (LDPE) into ethylene using catalytic processes. It compares the technoeconomic and life cycle impacts of this novel method against traditional ethane cracking. Findings show reduced emissions and lower costs, highlighting the sustainable potential of upcycling plastic waste.

Published on 2025-11-01 by Sarah Williams, Minwook Kang @MDPI
Abstract: Observing and measuring public life is essential for designing inclusive, vibrant, and climate-resilient public spaces. While urban planners have traditionally relied on manual observation, recent advances in open-source Computer Vision (CV) now enable automated analysis. However, most CV sensors in urban studies focus on transportation analysis, offering limited insight into nuanced human behaviors such as sitting or socializing. This limitation stems in part from the challenges CV algorithms f[...]
