Emerging bioeconomy opportunities in Africa

The report examines the bioeconomy potential of Croton megalocarpus Hutch in Kenya through a case study of Eco Fuels Kenya (EFK). EFK has developed a circular value chain that transforms croton nuts into biofuel, poultry feed, organic fertilizer, and biopesticides, providing alternative income for over 5,000 subsistence farmers. While the model demonstrates success in gender inclusion and resource value-addition, it faces challenges from a lack of national bioeconomy policy, inadequate government incentives, and climate-related yield fluctuations.

• Croton megalocarpus Hutch is a drought-resistant, fast-growing canopy tree indigenous to eight East and Southern African states, with seeds containing approximately 32% oil content.
• Eco Fuels Kenya (EFK) operates a circular bioeconomy model that processes croton nuts into multiple value-added products: biofuel (10% of nut content), organic fertilizer (600 kg per tonne), poultry feed (200 kg per tonne), and biopesticide vinegar (10 lts per tonne).
• The EFK business model provides alternative income to over 5,000 subsistence farmers across 17 Kenyan counties, with a high level of female participation; 70% of the 6,000 farmers involved are women.
• The bioeconomy approach has created conservation synergies, as farmers who previously used croton trees for firewood and charcoal now preserve them to sell the nuts.
• Kenya lacks a comprehensive national bioeconomy or bioenergy strategy, and the current regulatory system does not provide incentives to foster wider bioeconomy development.
• Scaling up the croton bioeconomy in East Africa is hindered by insufficient government support, difficulties in local investment, and climate change factors that shift collection areas further east.
