Options to promote use of sustainable energy in potato chips manufacturing in Rwanda
The lack of access to energy in Rwanda poses a challenge to the development of the agro-processing sector. Energy produced from potato processing waste could be an economically viable and environmentally sustainable way of increasing energy access in the agro-food processing sector in Rwanda. The waste oil from frying the potato has the potential to be used to produce electricity or to be transformed into biodiesel. This can result in the dual benefit of producing environmentally sustainable, low carbon energy as well as prevent waste cooking oil to get back into the food value chain. This report presents an assessment of the viability of using waste cooking oil from potato processing and other residues to produce energy. The report analyses a number of different combinations of factory set ups, systems and technologies. The results show that a limiting factor for the viability of recycling the waste cooking oil to produce energy are the current volumes collected. This results in a higher cost of electricity production on site compared to current price of grid electricity. Additionally, for biodiesel production, the results suggest that the domestic production and consumption of biodiesel may be technically possible and economically feasible, but its success would primarily depend on developing a waste cooking oil collection system as well as supporting policies.
