Pollution reduction with processed waste materials
… aimed at providing an understanding into the waste management options available for developing countries and also to provide insight into the possible application of the processed materials during the waste management processes, thereby helping in converting the waste materials which would …

Environmental risk management system design for hazardous waste materials
Hazardous materials can be generally deemed as any material which, because of its quantity, concentration, or physical, chemical, or infectious characteristics, may cause, or pose a substantial or potential hazard to human health or the environment. In the context of "sustainable development", most …

Optimisation of use of waste materials by Rhodopseudomonas palustris
… manufacture is an increase in the production of waste glycerol – a low-value by-product. There is currently no cost-effective, ecologically sound solution for how to use or dispose of this waste glycerol. However, metabolising that waste biologically (bioremediation) is an option with …

Rare Earth Extraction from Clayey Waste Materials by Alkali Pretreatment
… extract REEs from low-REE-grade clayey waste materials (e.g., coal-based clays). However, the low REE grades and poor leachability of REE-bearing species still make the recovery of REEs from coal-based clays challenging. The primary objective of this study is to develop leaching …

Super green: an architect’s redesign of concrete façade panels using waste materials
… a concrete façade panel from industrial waste that is bioreceptive, meaning it can sustain plant growth on its surface.<br/><br/>The research is a multi-disciplinary PhD that takes a whole view of the material development process from inception of idea to fully formed material and …

Fundamental studies of the behaviour of biomass and waste materials in gasification systems
… and behaviour of a range of biomass and waste materials, relevant to their utilisation as fuels in gasification systems. The range of fuels studied includes the biomass materials, cereal straw, short rotation coppice wood and pine round wood, and refuse derived fuels (RDF). These …

The microstructure of synthetic aggregate produced from waste materials and its influence on the properties of concrete
… aggregate produced using granite quarry fine waste blended with low grade ball clay as the binder. The investigation involved the use of various engineering tests and microstructural characterization techniques with special attention on the evolution of the microstructure of the aggregate …

Utilization of carbon-rich waste materials to reduce pesticide movement to groundwater in a sandy coarse-textured soil
… to examine effects of three organic carbon-rich wastes (i.e., waste activated carbon (WAC), digested municipal sewage sludge (DMS), and animal manure) on pesticide adsorption, leaching, and bioactivity in a sandy coarse-textured soil.

The Development of the Strength Index Method and Protocol for Assessing the Use of Solid Waste Materials in Concrete
The reactivity of the sludge ashes, as measured by the SIM showed that the sludge ashes in this study can be classified as reactive using the 28 day index values. Concrete containing sludge ash generally exhibited less compressive strength and modulus of elasticity when compared to concrete …

Development of a collaborative innovation management framework to assist in the utilisation of agricultural waste as building materials in Nigeria
The high cost of building materials in Nigeria is creating a shortfall of conventional building materials, which is also exacerbating the housing crisis in Nigerian urban areas. In view of the above, there is an urgent need to produce low cost, sustainable building materials that are affordable to …

Behavior and measurement of distributed sources in a shielding matrix using gamma spectroscopy
… the Department of Energy generates transuranic waste materials. Some of these wastes are present in large waste containers. The accurate assay of these waste materials in large containers poses unique challenges. These wastes have radioactive sources that are spread throughout the container with …

Bioremediation of waste by the bacterium Rhodopseudomonas palustris
… it an ideal candidate for the remediation of waste materials by metabolism. Our societies produce large amounts of waste materials, which require processing and safe disposal, but could instead be used as resources to produce fuel and energy or sustainably recycled into new materials. R. …

Developing a cost effective construction and demolition waste management plan
Concern over construction and demolition (C&D) wastes is becoming a prevalent part of any construction project. Historically, landfilling waste materials was the standard solution for most contractors, but as tipping fees have risen dramatically over the past five to seven years, many contractors …
