- Description: Abstract: The economy of Zimbabwe has deteriorated over the years with hyperinflation. In the years 2006 to 2008 the conditions worsened and in 2009 a multicurrency system including the US dollar was introduced, however investment in the industry did not strengthen and a number of challenges are still faced by the industry. A main feature of the Industry in Zimbabwe had been the steel and steel related manufacturing industry which was key for both domestic and foreign markets. The motivation for this study was to investigate and propose st rategies for enhancing sustainability of steel making companies in Zimbabwe. The aim of this research was to undertake a requirements analysis from the steel companies and identify the main challenges from the point of view of steel production. From these challenges the paper aimed to help codefine some of the possible solutions the companies could consider. Sharing the findings could help companies pick up best practice and inform policy makers in developing new frameworks for improving industrial sustainability.

- Description: Abstract: Global warming effects have become very apparent in many parts of the world causing governments to force their industries to be environmentally conscious. Small individual contributions will help abate global warming. The steel industry, if left unattended, has great potential of releasing greenhouse gases into the atmosphere. In this paper a life cycle assessment (LCA) for steel balls used as grinding media in mines that are produced at Craster International in Zimbabwe is discussed. Knowing the life cycle environmental impacts of the steel balls is very important since they produce greenhouse gases in their production. The emitted carbon dioxide, sulphur dioxide, nitrous oxides and other trace greenhouse gases have adverse effects on flora, fauna, water bodies and humans. Interviews, questionnaire and direct observation and measurements were used to generate the data. The data is analyzed and a new LCA diagram from the results of the research and recommendations was made.
