Thesis (MSc)--Stellenbosch University, 2005.<br>ENGLISH ABSTRACT: There is increasing pressure on factories and government to practise cleaner technology. The public is becoming more and more environmentally aware and external pressure from international competitors is also forcing companies to adopt environmentally sound production practices. Our natural resources and the environment need environmentally friendly practices. Waste minimisation is not only prudent practice for manufacturing industries, but is also an integral part of environmental regulations in many countries, including

Abstract:

The biosorption of copper, nickel, gold and platinum from single metal aqueous solutions by the nickel hyperaccumulator Berkheya coddii plant biomass was investigated. Potentiometric titrations of the biomass and determination of optimal sorption pH for each metal showed that nickel ions were released from the biomass into solution. The presence of free nickel ions interfered with the uptake of the other three metals and further biosorption investigations were discontinued. Three fungal isolates found colonising metal solutions were cultured and screened for their ability to remove 50 mg.l⁻¹ o

M. Tech. Chemical Engineering<br>Environmental pollution due to heavy metals is a global crisis. Contamination as a result of heavy metals from industries such as mining operations, electroplating facilities, etc. pose serious threats to the aquatic ecosystem, people and the environment. Lead (Pb), cadmium (Cd), zinc (Zn), copper (Cu), mercury (Hg) and nickel (Ni) are common examples of heavy metal ions often detected in most effluents. They are characterised by their non-biodegradability, toxicity and tendency to accumulate in living organisms, and thereafter, cause various diseases and disor

Abstract:

Every time a good is produced, waste occurs as an unwanted by-product. Waste has become a real environmental issue across the world, contributing to the degradation of the environment and human health. As part of a local and international effort to lessen industrial pollution, a concept to reduce waste production at source was introduced to companies in the early 1990s. Pioneered in the Netherlands and the United Kingdom (UK), this concept has been termed 'waste minimisation'. Waste minimisation is achieved by implementing changes to business practices and processes, such as improved housekeep

Abstract:

Environmental legislation is becoming more stringent as people are realising the need for conservation and a reduction of environmental degradation in order to facilitate sustainable development. To ease legislative pressures, companies need to work together in symbiotic networks, whereby co-operation between companies results in far more innovative practices than if the companies acted individually. Success in an industrial network is largely dependent on cleaner production, where industries seek to redirect from waste treatment to waste minimisation. Cleaner production has already received i

South Africa is facing numerous challenges that pertain to increasing water deficit and pollution of water resources. Only 40 out of 821 wastewater treatment works in South Africa achieved Green Drop certifications in the 2010 Green Drop assessments (DWA, 2011). This is not only threatening net water availability but also human health. South African water sources are comprised of 77 % surface water, 14 % return flows and 9 % groundwater (van Vuuren, 2009). This study was therefore intended to explore the quality, quantity and treatability of corn wet milling effluent resulting from Tongaat Hul

The study investigated solid waste management in the Mafikeng Municipality including the attitudes of the residents towards the waste management services rendered by the municipality. The study found the followings: the main sources of waste were from households due to minimal industrial activity in the area; that the residents had negative attitudes and perceptions about the waste management services provided by the Municipality. The majority of residents were not involved in the identification of needs and management of solid waste. They wanted to take an active role in the planning, design

Although the activated sludge process has been adopted to treat this industrial waste water , lots of problems were experienced by the inhibitory effects of toxic compounds that are found in industrial effluents and the foaming stability that was very high. Industrial waste water treatment using sludge processes was found to be more challenging than the normal municipal waste water treatment although the principle is the same; the foam

Abstract:

A number of environmental, social and economic problems are associated with waste disposal in landfill operations. The potential hazards associated with landfill operations are numerous and include fatal accidents, infrastructure damage, pollution of the local environment, harmful air emissions, to simple nuisance problems – such as dust, odour, vermin, and noise pollution. Further challenges include the availability of land and lack of municipal or other financing in the face of rising operation costs. Landfilling is, however, seen by many as an environmentally responsible and cost-effective

Industrial effluents with high concentrations of heavy metals are widespread pollutants of great concerns as they are known to be persistent and non-degradable. Continuous monitoring and treatment of the effluents become pertinent because of their impacts on wastewater treatment plants. The aim of this study is to determine the correlation between heavy metal pollution in water and the location of industries in order to ascertain the effectiveness of the municipal waste water treatment plant.
