Where is biogas used in south africa

In summary, Africa has vast untapped potential for the utilisation of various different organic and inorganic materials for the production of renewable, decentralised power.

As a pioneering project, BBP was deemed too high risk for commercial lenders at the time.

The plant supplied its first power into the national grid on 10 October The project also improves waste management on the farm, reducing the amount of manure from intensive farming going into the environment. The plant has also created over 50 direct and indirect permanent jobs and about temporary jobs in a rural area, where employment opportunities are generally scarce.

Introduction Energy overview in Africa Africa is a net energy exporter, but the majority of its population lacks access to clean energy, and many African countries rely on imported energy Amigun et al.

Methods The primary research method used is to calculate the required parameters based on values obtained from a literature study. Literature review 2. The following gaps are addressed in this study: i The availability of other types of organic wastes such as kitchen and human waste for feeding bio-digesters. Methodology 3. Biogas requirement was calculated using Equation 4 for the following conditions: i Substitution of fuelwood used for cooking. Data analysis A comparative study of the following was conducted, and the results are given in Section 4.

Recommendations The following recommendations are made: i Launching of a pilot scale study to determine the actual replacement of fuelwood with biogas as well as the feasibility of domestic biogas technology in low-income South African households.

Other sources and partners for this waste include the South African Local Government Association SALGA , animal farms, pulp and paper producers, food and dairy industries and abattoirs where the opportunities for waste pre-treatment, the recovery of nutrients from digestate and farm biogas installations present good business cases. The time for talking is over as indicated by the recent serious biogas initiatives signalling the acceleration of the development of a sizeable biogas industry in Southern Africa.

Early lessons learnt from failed biogas installations both abroad and at home serve as a timely and expensive reminder that construction shortcuts and simply transposing foreign methodologies and designs are not sustainable. Biogas feedstock options in South Africa differ vastly from developed countries where maize silage, ground cereal, rape and rye seeds represent a common feedstock component. Leaking digestate and methane gas are examples of very serious environmental dangers arising from construction shortcuts.

Aside of the obvious benefits there are positive signs that many of the inherent threats to and weaknesses of the biogas industry are being addressed, viz:.

Key challenges which remain barriers to further biogas growth in South Africa are the scarcity of water and the fact that there is simply no generic solution. You cannot simply transpose a biogas technology from one continent, country and region to another, as local climatic conditions and the availability and proximity to feedstock strongly influence the design of the digester, agitators, and anaerobic technology employed batch reactor vs.

This relatively young technology is dynamic, so expect continual improvement of current designs and methodologies. This is clear from ongoing research at the German Biomass Research Centre in Leipzig, Germany, where the objectives of further research focus areas on biogas are:.
