Giraffe Bioenergy

Standing Tall for Food and Fuel

We are establishing local manufacturing of ethanol cooking fuel  from cassava to serve the growing clean cooking market in Kenya impacting rural livelihoods.

Build 45 million litres of ethanol cooking fuel capacity by 2028

Increase the incomes of 5,000 smallholder farmers, mainly women

Improve food security for 20,000 members of the community

Problem & Solution

We import the majority of ethanol cooking fuel used in Kenya despite having all the resources necessary for robust domestic production from cassava including:

High demand for ethanol cooking fuel

Established last-mile distribution infrastructure

Ample under-utilised semi-arid land

Plenty of skilled and semi-skilled labour

Protective tariffs and political will

Empower local families

Our Mission & Vision

Our mission is to establish rural bioeconomies increasing the incomes of women in farming communities through large-scale cassava farming and manufacturing of ethanol cooking fuel.

Our vision is to leverage the central role that women play in the value chain  in cassava production and processing and as beneficiaries of ethanol cooking fuel replacing charcoal and kerosene.

Our Impact

SDG 5, Gender equality
SDG 1, no poverty
SDG 8  decent work and economic growth

Income generation and poverty alleviation for women and communities

Commercial cassava farming provides rural communities, especially women, with opportunities for income generation. By participating in the production and sale of cassava, communities can earn a steady income, which drives investment in education, healthcare, and other basic needs

SDG 2, zero hunger

Food security and nutrition

Cassava is an ideal feedstock for both food and fuel 

Giraffe Bioenergy utilises semi-arid, non-fertile land in areas with unreliable rains that are prone to drought and are therefore not suitable for food production. We have adopted and rapidly propagated drought-resistant edible cassava strains developed by the International Institute for Tropical Agriculture that can thrive in semi-arid land

SDG 15, life on land
SDG 12, climate action

Climate Action and Environmental Sustainability

Sustainable cassava commercial farming using improved drought and disease tolerant varieties promotes sustainable practices like soil management, water conservation, and agroforestry, enhancing climate resilience, biodiversity, and environmental sustainability
