Assessing the potential for electricity generation from animal waste biogas on South African farms

ABSTRACT Electricity generation using animal manure is practised extensively in many parts of the world to improve farm profitability and to increase the contribution of renewable energy. This research assesses the financial viability of using pig and dairy manure to produce electricity on a small sample of farms in South Africa. Financial feasibility studies were carried out for both pig and dairy farms. This study also assessed the level of production and incentives that are necessary to make biogas a viable option for electricity generation. The results show that electricity generation on pig farms is potentially viable. This could be enhanced with various types of incentives. The sample of dairy farms on the other hand does not show much potential.
