Abstract:

This report explores the need for re-utilization of concrete waste materials in contrast to disposal by landfilling. Potential applications for the beneficial and cost-effective re-utilization of waste concrete materials are presented. Factors affecting the feasibility of re-utilization of concrete waste materials are discussed. Reduction of construction project costs and minimization of environmental impact can be realized as the result of removing concrete waste materials from the solid waste stream.

Abstract:

Thesis (MTech (Chemical Engineering))--Cape Peninsula University of Technology.<br>While biodiesel has the potential to resolve the energy crisis, its production is hampered by both feedstock and catalyst availability. The aim of this current study is to investigate the production of biodiesel from waste vegetable oil (WVO) as feedstock under heterogeneous catalysis, mediated by calcined eggshell ash. WVO, characterised by 9% free fatty acid (FFA) and 0.17wt% water content, was employed as feedstock in the biodiesel production via transesterification reaction. The composition of WVO was determ

Abstract:

Anaerobic digestion has great potential as an energy source. Not only does it provide an effective method for waste mitigation, but it has the potential to generate significant quantities of fuel and electricity. In order to ensure efficient digestion and biomass utilization, however, the system must be continuously maintained at elevated temperatures. It is technically feasible to supplement such a system with outside energy, but it is more cost effective to heat the system using only the produced biogas. While there is considerable literature covering the theory of anaerobic digestion, there

This research investigates complete recycling and utilization of waste concrete to produce new structural concrete through geopolymerization. The investigation was conducted through both macro-and micro/nano-scale studies. First the geopolymer paste synthesized using a mixture of waste concrete fines (WCF) and class F fly ash (FA) as the source material and a mixture of NaOH solution (N) and Na2SiO3 solution (SS) as the alkaline activating agent was studied. Various NaOH concentrations, SS/N ratios, and WCF contents were used to produce geopolymer paste specimens in order to study their effect

Abstract:

Mineral carbonation allows to permanently store CO2 into materials rich in metal oxides. However, mineralization technologies still suffer of slow reaction rates and low carbonation efficiencies and, to improve them, there has been increasing interest in employing waste streams as feedstocks. In light of this, the aim of this thesis was to determine the potential use of wastes for permanent sequestration of CO2. It was found that waste streams available for mineral carbonation in the UK have a capture potential of 1Mt/year, and in many cases, waste resources are located close to the CO2 emitte

To maintain the sustainability of cement and concrete production, there is a trend to use wastes in their production.

Abstract:

Many industrial processes generate large amounts of waste. Typical examples include the fertiliser industry (phosphogypsum), ferro-alloy and steel producers (slag), as well as the power generating industry (fly ash). Although some waste products are currently used to a limited extend (e.g. fly ash and cement in cement), there is a constant need to find more uses and newapplications for these. This investigation describes work done to develop a novel ceramic body, which can potentially be used as a ceramic filter for purification of waste water and potable water.

The demand for air conditioning keeps rising, especially in developing countries where the standard of living has improved. This results in an increased consumption of electricity and puts further pressure on the power grid.

An alternative technology for producing cooling is thermally driven cooling where the installment of an absorption chiller could utilize waste heat from existing industries to provide cooling to buildings.

Abstract:

Nutrients present in digested animal waste can be utilized for algae cultivation under suitable conditions. Algal growth, however, depends on the chemical forms and speciation of these nutrients. In this study a chemical equilibrium model was first used to describe nutrient speciation and predict conditions that enhance the solubility of nutrients in anaerobic digester effluent. Dilution with water and separation of large particulates greatly improved nutrient availability and light penetration - conditions favorable for algal cultivation. Algae growth was tested using three strains - Scenede

Abstract:

The utilization of composed caged-layer waste (CCLW) in diets for pregnant ewes fed cereal straw was evaluated. Five sheep were assigned to five diets containing, 0, 5.72, 11.37, 23.80, and 32.69% CCLW in a 5x5 Latin square design. Water intake, feed intake and feces output were measured. Feed and feces were analyzed for dry matter, crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF), organic matter, hemicellulose and minerals. Thus, nutrient digestibility and nitrogen balance could be calculated. Forty dry, pregnant ewes in the last third of generation were assigned to fo

Abstract:

Surface preparation is the key factor in determining the success of a protective coating system and its ultimate objective is to create proper adhesion of a coating over an underlying substrate. Abrasive blast cleaning involves mechanical cleaning by the continuous impact of abrasive particles at high velocities on to the substrate in a jet stream of compressed air. Industries that use abrasive blasting include the shipbuilding industry, automotive industry, and other industries that involve surface preparation and painting. Materials from different origins can be used as a blasting media incl

Abstract:

The slags from iron-steel and zinc industries are rich in metal oxide contents like FeO, MnO, CaO. However, these slags are not used extensively, except some usage in the cement industry. These slags can be used in removing H2S from waste gases from different industrial sources. The purpose of this research is to study the effect of initial concentration of H2S on the capacity and sorbent efficiency of waste materials from iron-steel and zinc industries. Experiments were conducted in a 25 mm-quartz reactor with simulated gases containing H2S as reactive gas. Breakthrough curves for sulfidatio

Content: Leather industry is one of many traditional, characteristic and ascendant industries. During the development of Leather industry, the problem of a certain the waste of resources and environmental pollution has been yielded. The waste tallow is one of the problems should be solved quickly. Based on the problem of the waste of resources and environmental pollution form the waste tallow during the leather industry, act waste beef tallow from tannery as raw material, detection of its physical and chemical properties, de-colorization, deodorization, amidation, esterification and sulfitatio
