- Description: This paper investigates the technical advancement in the production of ethanol in Southern Africa and examines the utilisation of ethanol and of the by-products derived from its production process. Although numerous studies have identified the use of ethanol as an alternative energy source especially in Brazil and the USA, very little data and analytical attention has been given to Southern Africa. This paper therefore builds on that and on the study done on alternative energy in Southern Africa such as the coal to liquids processes by Sasol. The paper demonstrates that the expansion of bio-ethanol as an alternative fuel would result in the reduction of Greenhouse gasses emissions and an increase in the rural economic development in the Southern African region. In conclusion the paper emphasises the need for a speedy upgrading of the ethanol technological methods in order to expand the use of bio-ethanol as an alternative energy. In addition the paper strongly recommends the supplementation of coal for the generation of electricity, as well as the progressive replacement of petroleum fuelled vehicles with the ethanol blend or the complete replacement with ethanol-fuelled ones.

- Description: Abstract: The Biofuels Industrial Strategy established by the government of South Africa in 2007 has emphasised the need to understand the potential benefits and consequences of developing biofuels in the country. Life cycle assessment (LCA) is a preferred tool to measure energy and environmental performances of biofuel production; however, LCA relies heavily on data and developing a life cycle inventory (LCI) plays a crucial role in any LCA studies. The lack of availability and difficulty in obtaining data from reliable sources can provide a great challenge during the process of developing biofuels LCI. This study develops a LCI database for the production of ethanol using sugarcane molasses in South Africa. The inventory includes all the input and output data associated with various sub-system of ethanol production. Relevant data are collected through national statistics and various literatures. The LCI has been developed as a first step towards the LCA studies which can assist in measuring the performance of South African ethanol development in the future.
