Design Experiment for Leveraging Material Value Coal Ash as Material Mixture of Paving Block

MATEC Web of Conferences, 2018
The coal-fired thermal power plant is the main source of coal ash production. Coal ash collected at the bottom of the furnace (boiler) is called coal bottom ash (CBA) and fly ash remaining combustion called coal fly ash (CFA).

Electrolytic (C2CNT) Carbon Nanotubes Made From CO2 as an Inexpensive Carbon Sink and High‐Capacity Li‐Ion Battery Graphite Replacement

EcoEnergy, EarlyView.
Carbon‐negative carbon nanotubes produced by molten CO2 electrolysis offer a low‐cost, high‐performance alternative to graphite in Li‐ion battery anodes. Replacing conventional carbon materials with electrolytic CNTs can improve battery capacity and charging performance while reducing costs and contributing to carbon mitigation.

Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

Energy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.
