An emerging leader and developer of Green Alternatives for Energy And Agricultural Food crops in Africa

Developing a BioEthanol Refinery from Cassava for Zambia

Cassava has the highest known rate of sucrose synthesis of any plant surveyed to date (80-90% Carbohydrates-3.05Mcal/kg)

Potential starch yields are greater than most other starch producing plants when grown under ideal conditions (90 tons FW/hectare)

Cassava is drought tolerant Cassava grows well even in poor soil conditions Cassava is protected from most

pests and herbivores by cyanogenic glycosides

Cassava requires little maintenance or labor in the field

1kilogram = 2.2 pounds

Tropical/Sub-tropical crop

About GroAfrica

GroAfrica Zambia is part of GroAfrica International Ltd. GroAfrica Zambia is focused in a BioEthanol refinery plant for Zambia to serve the local market, cutting importation of ethanol for fuel blending as mandated by the Zambian Government. The market will be for fuel blending, power generation/electrification and to introduce a market for ethanol as a replacement for charcoal based cooking. GroAfrica also is developing plantation based Moringa, and to grow Soya and a food crop business – reducing net importation to Zambia of soya products.
