- Description: Abstract: The life cycle of an aircraft consists of design, production, operation and decommissioning phases. For an airline the main focus is on the maintenance process during the operation phase. This paper presents a case study of an airline facing a challenge of increasing maintenance cost. The objective is to understand factors that drive increase in cost. Maintenance cost, flight hours, flight cycles, dispatch reliability and pilot reports were analyzed to find out the maintenance cost drivers. The study identified that the aircraft which dominated the maintenance costs had the highest flight hours, and the lowest dispatch reliability in the fleet.

- Description: Abstract: The world is neither globally successful in remanufacturing and re-use of products nor recycling of waste materials. This requires a combination of circular economy management systems, business models and novel technologies. There are contrasting views in literature regarding models for a circular economy. The main views are built on extended producer responsibility and on the role of end users. This paper is based on a study of the South African industry’s view of circular economy models, drivers and sustainers, with particular focus on composite waste. Cost reduction was found to be the strongest driver and sustainer for recycling of composites. Thus, maximizing opportunities to reduce cost is a key factor in encouraging South African companies to embrace the circular economy. This is important in developing appropriate national models for managing the transition to a circular economy.

- 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.
