Sustainability, 2023 Using industrial waste as part of the raw material to produce cement-based materials is considered to be a sustainable cement and concrete materials production method. Coal gasification fly ash (hereafter CGFA) is a solid waste produced during the coal gasification process.

Mechanochemically Assisted Coal Fly Ash Conversion into Zeolite
Materials, 2022 Mechanically treated fly ash (FA) was utilised to provide Al and Si atoms for zeolite synthesis. A combination of mechanical fly ash activation and classical hydrothermal synthesis led to favourable dissolution of activated fly ash and improved crystallization of zeolites.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Bio-Desilication of Coal Fly Ash and the Impacts on Critical Metal Recovery
MetalsCritical metals such as rare earth elements (REEs) are primarily associated with silicates and aluminosilicates in coal fly ash, resulting in poor REE recovery.

What drives animal responses to high severity fire? The role of functional traits
Biological Reviews, EarlyView.ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Business Strategy and the Environment, EarlyView.ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Business Strategy and the Environment, EarlyView.ABSTRACT Industrial symbiosis (IS) represents a key strategy for industrial decarbonisation (ID) by converting one industry's waste into valuable inputs for another, reducing emissions and resource extraction. Scientific studies have explored the concept, implementation approaches and theoretical foundations of IS.

Efforts to examine coal and fly ash
International journal of health sciences, 2022 Fossil fuels have met a large portion of the world's ever-increasing energy demands as technology has progressed. Coal-burning in thermal power plants releases gaseous and particulate pollution into the environment, as explained in previously. During the coal-burning fuel cycle, many constituents are released into the atmosphere.

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport
Chemistry – A European Journal, EarlyView.Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor.
