The practices of mining and ore processing are used in many countries around the world to extract and concentrate the valuable natural resources found within the rock bodies which make up the earth’s crust. However, the ...

Severe water scarcity, high health standards, and strict disposal limits have necessitated the development of novel and robust strategies for wastewater remediation and water quality analysis at lower cost with reduced ...

This study examined two novel approaches for the geopolymerisation of fly ash produced at thermoelectric power stations by combustion of coal. The first approach involved the use of cullet, a post-consumer glass waste, to ...

With the cost of sludge management on the rise, the volume reduction of municipal wastewater sludge is becoming an increasingly important issue for wastewater treatment plants. Current research is focused on pretreatment ...

Kraft lignin is water insoluble and has limited end-use applications. The main objective of this MSc studies was to rend kraft lignin water soluble, and various value-added products including dispersants and flocculants. ...

Carbonation negatively affects the durability of steel-reinforced concrete structures by causing a decrease in pore solution pH, thus facilitating corrosion which eventually leads to cracking and spalling. Different ...

Electrokinetic remediation is an emerging in-situ technology for cleaning contaminated soil. The contaminants are mobilized by passing a low-level direct current between a row of positively charged electrodes (anode) and ...

Lignin is one of the most abundant biopolymers on earth, constituting approximately 30% of the dry weight of softwoods and 20% of hardwoods. It is a renewable, non-toxic, commercially available and low cost natural resource ...

The processes used to produce manufactured gas for heating, cooking and lighting purposes in North America from the early 1800s to the mid-1900s have generated by- products such as coal tar containing Monocyclic ...

The quality of groundwater in many regions around the world has been compromised due to pollution from anthropogenic activities such as deposition of solid wastes containing heavy metals in landfills, industrial spills and ...
