Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Beyond Technological Maturity: Understanding the Institutional Trajectories of Carbon‐Derived Renewable Methane in the European Energy System

EcoEnergy, EarlyView.
We demonstrate that the limitation of bioCO2‐derived methane is systemic rather than technological, and provide a validated framework for traceability, certification, and policy alignment enabling its integration into RFNBO‐compliant value chains and EU energy systems. ABSTRACT Renewable methane derived from biogenic CO2 (bioCO2) occupies a paradoxical

Circularity Before Strategy: Translating the Circular Economy for Environmental Policy and Governance in Emerging Economies

Environmental Policy and Governance, EarlyView.
ABSTRACT The circular economy (CE) is now a cornerstone of global environmental policy. However, current debates often frame CE as a future‐oriented strategy to be adopted or scaled, implicitly assuming that emerging economies and the Global South are starting from strictly linear conditions. Drawing on practice‐oriented and institutional perspectives,

Profit optimization in biogas plants via flexible feed rate and flexible energy production

Energy Conversion and Management: X
Achieving fully flexible operations of biogas plants poses major challenges. The complexity of modeling the anaerobic digestion process and the various kinds of feedstock used in each plant make it difficult to develop a universal solution. Nevertheless,

Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

Energy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon
