Karakteristik Mekanis dari Campuran Abu Terbang dan Abu Dasar dalam Geoteknik [PDF]

, 2017
Generally, coal are used for fuel by industry factory at Indonesia. Coal burning produce two of kind waste, that is fly ash and bottom ash. Utilization of coal waste is not optimal yet at this time.

Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste

International Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.
ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

Evaluasi Pemanfaatan Abu Terbang (Fly Ash) Batubara sebagai Campuran Media Tanam pada Tanaman Tomat (Solanum Lycopersicum) [PDF]

, 2012
As the impact of rising oil prices, the coal consumption in industry has increased, a consequence of coal waste in the form of fly ash and bottom ash to be very abundant. This research was conducted to determine the benefits of fly ash as planting media.

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Precipitation of Germanium from Coal Fly Ash Leachates

Coal Combustion and Gasification Products, 2010
The valorization of a coal gasification fly ash was studied by leaching the fly ash using different aqueous solutions followed by the subsequent precipitation of the germanium solubilized from the ash. Experimental investigations were focused on the precipitation of a germanium2catechol (CAT) complex with cetyl trimethyl ammonium bromide (CTAB).

Leaching characteristics of fluoride from pond ash [PDF]

, 2011
Now, more than 100 million tons of coal fly ash is produced annually in India from combustion of coal in power plants. It is expected that about 150 million tons of coal ash will be produced due to burning of coal in power plants by the year of 2015 ...

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

Chemie Ingenieur Technik, Volume 98, Issue 3, Page 78-84, March 2026.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.
