Conversion of no/low value waste frying oils into biodiesel and polyhydroxyalkanoates [PDF]

open access: yes, 2019
A sustainable bioprocess was developed for the valorization of a no/low value substrate, i.e. waste frying oils (WFOs) with high content of free fatty acids (FFAs), otherwise unsuitable for biodiesel production.

Bridging Green Chemistry and Circular Economy: A Pathway to Sustainable Polyester Plastics Through Feedstock, Synthesis, and Waste Upcycling

open access: yesAdvanced Science, EarlyView.
This review summarizes green and low‐carbon strategies throughout the entire life cycle of polyester plastics, including sustainable monomer synthesis, optimization polymerization, efficient recycling, and advanced upcycling technologies. The synergistic implementation of these strategies is expected to significantly promote the development of a ...

Scalable Wheat Bran‐Algae Composites for Edible Electronics with Spray‐Coated Food‐Grade Conductive Inks

open access: yesAdvanced Electronic Materials, EarlyView.
A fully edible wheat bran–algae substrate is fabricated through scalable mould‐compression and spray‐coating, enabling robust, food‐grade platforms for sustainable electronics. A chitosan barrier improves water resistance and ink compatibility, while activated‐carbon conductive films form uniform electrodes with Ohmic behaviour.

Biopolymer‐Coated Paper Composites for Sustainable Packaging

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To
