Abstract In light of the growing urgency to address environmental degradation and improve carbon sequestration strategies, this study rigorously investigates the potential of Cistus ladaniferus as a viable feedstock for biochar and activated carbon production. The influence of pyrolysis temperature, heating rate and particle size on biochar yield was systematically examined. The results demonstrate that increasing pyrolysis temperature and heating rate significantly reduces biochar yield, while particle size plays a crucial role in thermal degradation and biochar retention. To evaluate the structural and chemical properties of the materials, various characterization techniques were employed, including Fourier-transform infrared spectroscopy… More >

Abstract The use of agricultural residues in biocomposite production has gained increasing attention, driven by several benefits. Converting agricultural by-products into bio-based materials within a circular economy represents a sustainable strategy to mitigate lignocellulosic waste, reduce reliance on fossil resources, and lower environmental pollution. This approach also creates economic opportunities for rural African communities by generating diverse income sources for workers in collection, processing, and manufacturing. As a result, the integration of agricultural residues into biocomposites production not only addresses environmental concerns but also fosters economic growth and supports rural development.

Abstract In recent years, degradable materials to replace petroleum-based materials in preparing high-performance foams have received much research attention. Degradable polymer foaming mostly uses supercritical fluids, especially carbon dioxide (Sc-CO2). The main reason is that the foams obtained by Sc-CO2 foaming have excellent performance, and the foaming agent is green and pollution-free. In current research, Poly (butylene adipate-co-terephthalate) (PBAT), poly (lactic acid) (PLA), and other degradable polymers are generally used as the main foaming materials, but the foaming performance of these degradable polyesters is poor and requires modification. In this work, 10% PLA was added to PBAT to… More >
