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

open access: yesChemSusChem, 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

open access: yesEcoEnergy, 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

Experimental Investigation and ANN‐Based Prediction of CI Engine Performance Fueled With Waste Plastic Oil–Diesel Blends Containing Al2O3 Nanoparticles

open access: yesEnergy Science &Engineering, EarlyView.
Waste plastic oil–diesel blends enhanced with Al2O3 nanoparticles were experimentally evaluated in a compression ignition engine under varying injection timings and modeled using artificial neural networks (ANNs). The optimized WP20PD + 1000 ppm blend improved brake thermal efficiency and reduced fuel consumption, while ANN prediction achieved high ...

The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

open access: yesEnergy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.
