Zambia is home to diverse bioenergy feedstocks.
Bioethanol can be produced from sugar-based plants such as sugarcane, sweet sorghum, pineapple, mango and local wild fruits such as Masuku, and from starchy-based feedstocks such as cassava, sweet potatoes, maize, rice, and sorghum.
Biodiesel is made from plant oils and animal fat. Plant oils can be obtained from plants such as soybeans, palm, jatropha, sunflower, groundnuts, cotton, moringa, Mubula (Parinari Curatelli) and Mungogo (Ricinodendron Rautaneii).
BioCNG and bioelectricity can be produced from different sources of biomass such as Agricultural residues – Farm/agricultural waste derived from farms or food processing; Food waste – Wastes produced as by-products from food-processing plants or after consumption by consumers; Industrial waste – Bio-wastes from industries, such as sugar manufacturing plants and ethanol distilleries; Municipal solid waste (MSW) – Organic fraction of MSW, garbage, and sewage slurry; and Energy crops – Crops that have high energy content grown specifically for this purpose, such as Napier grass, Giant King Grass and Miscanthus. The table below gives gas yields and methane content in some feedstocks for biogas/bioCNG production.
|FEEDSTOCK||GAS YIELD (m3/kg)||METHANE (%)|
|Municipal solid waste||0.308||60.0|
|Jatropha curcas seedcake||0.640||66.5|
|Pongamia pinnate seedcake||0.738||62.5|
