Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Performance Assessment and Lab‐Scale Economic Evaluation of Alkaline Extraction and Comparative Precipitation of Cyanobacterial Proteins

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Algal proteins from cyanobacteria serve as a natural source of biopolymers. The principal challenge manifests as nonoptimization of unit operations in downstream process accounting for higher costs. This study focuses on process assessment of unit‐operations for selecting suitable recovery strategies not only based on yield, but also considers

Optimizing Charpy Impact Strength of Material‐Extruded PLA Through Layer Height, Raster Angle, and Infill Geometry

open access: yesJournal of Applied Polymer Science, EarlyView.
Charpy impact performance of material‐extruded PLA is governed by the coupled effects of layer height, raster angle, and infill geometry. Full‐factorial testing identifies layer height as the dominant factor and reveals a strong layer‐height–raster‐angle interaction.
