- Description: Abstract: This study points to the biofuel industry as a potential business idea that can be used by a selected group that has to form and run a sustainable cooperative. Biofuel projects are considered in this study, focusing on how biofuel projects may be incorporated in the running of biofuel industry. The study investigated the opportunities of the emerging South African cooperatives in biofuels industry. We used the qualitative method to collect data. A total of 200 cooperative were studied through observations, interviews, and focused group interviews. Out of 200 small scale biodiesel plants situated in South Africa, 35 are in four provinces namely Mpumalanga, Western Cape, Kwa-Zulu Natal and Gauteng, where empirical studies were conducted in form of observations and interviews. Cooperatives are widely spread all over South Africa. The study however, focused on the cooperatives that are situated in Limpopo and Gauteng province. The researcher also attended several workshops and conferences that are related to development of South African cooperative and other social enterprises. Both the strategy of the cooperative and biofuels aimed at one most important aspect which is to merge the first and second economy. Both are in the emerging stage, and working on a common goal of educating and training those that are affected to achieve the aim.

- Description: Biofuels have a potential to extend and diversify South Africa’s energy supply, thus reducing dependence on imported fuels and pollution levels. Despite several biofuel policies and mandates, biofuel develop- ment in South Africa has stalled in the legislative process and no large scale commercial biofuel project has materialized yet. Developing biofuels, especially using food grains, is a big challenge to the government of South Africa due to issues related to food security, commodity prices, economic and social concerns, and impacts of land use changes on the environment. The production cost of feedstock and employment creation opportunities from agricultural production play a vital role in selecting suitable feedstock for the region. Since considerable investment and infrastructure will be required for continued supply of feedstock and efficient biomass conversion technologies, rigorous research and comprehensive studies are required to identify feedstock and technologies best suited for the successful establishment of biofuel industry in South Africa.

- Description: Abstract: A social life cycle assessment is a social impact assessment technique that aims to assess the social and socioeconomic aspects of products and their positive and negative impacts along their lifecycle. The focus is mainly on the impact on workers and communities at large, where production and consumption generally takes place.This work is justified, mainly because there is growing customer/market pressure on the state of the social and economic circumstances of production and services for products like bio-fuel. Issues like corruption, unionization of workforce, policies and laws in the creation of bio-fuels and its by-products are increasingly being recognised as important as they affect production largely.

Life-cycle inventory to assess and analyze biodiesel production in South Africa

- Description: Abstract: Biofuels, just like fossil fuels, are also associated with various environmental impacts along the productionconsumption chain. Those impacts need to be attributed to different products, as biofuel production generally yields one or more co-products, like animal fodder or soymeal, or may be a co-product of some other, higher-valued process, like bagasse from sugar cane for heat or electricity production. Life cycle assessments impacts of biofuels are usually studied in a comparative manner, in order to analyse which alternative amongst fossil or bio-based options has the lesser environmental burden.The inventory analysis shows that the inputs and outputs of the farming unit process are sensitive to the type of crop and region of produce. Water usage is a highly variable parameter, which emphasises the importance of rainfall and irrigation to the overall burden of the biodiesel system on water resources. Crop yields may differ by a factor of two, which is a significant difference in terms of land and non-renewable energy resources requirements. The oil and meal/cake content of the seed proves to be the most important parameter that influences the initial unit processes of the value chains.

- Description: Abstract: The City of Johannesburg (CoJ)’s existing modes of transport are not sustainable as the vehicles rely on fossil fuel and the natural gas other than renewable energy such as biofuels and biogas. Several African countries are already producing and commercializing biofuels; however, South Africa even though it has a biofuel strategy drafted in 2007; due to food security and political inaction, biofuel is not commercialised. There are 200 small scale producers of biodiesel, which is from used vegetable oils in South Africa. Renewable energies in South Africa has many opportunity and challenges. As South Africa, besides having to consider sustainable transport through the utilization of renewable energy source, it also needs these sources for generating electricity. Hence this study only chose to review the current state of two renewable energies, namely biogas and biofuels. The biofuels are because currently there are small scale biodiesel manufacturers who do not have the stable market for their final products and biogas is one of the selection due to the number of landfills which already exist in South Africa and other waste generation daily converting it into biogas.
