Based on the Malawi study, charcoal costs 6.0 to 10 US$/40 Kg bag (Malawi), or US$2,700/Ha for 15 tons of wood cleared. 6.0 to 10 US$/40 Kg bag (Malawi), or US$2,700/Ha for 15 tons of wood cleared. Pellets from wood shavings cost about 3.0 to 5 US$/40 Kg bag (Zambia, personal communications with Dr. Per Lofberg of Vagga till Vagga AB of Sweden) 3.0 to 5 US$/40 Kg bag (Zambia, personal communications with Dr. Per Lofberg of Vagga till Vagga AB of Sweden) Energy efficiency of selected cooking fuels Economics between charcoal and wood pellets

Feedstock Supply and Logistics Feedstock constitutes about 70% of final bioenergy product. Providing biomass for conversion into biofuels represents an economic opportunity for communities across Africa. This requires developing the technologies and systems needed to sustainably and economically deliver a broad range of biomass in formats that enable efficient use in biorefineries.
Feedstock Supply and Logistics (continued) The diverse biomass transformed by these technologies and systems must be consistent, quality-controlled commodity products that can be efficiently handled, stored, and transported to biorefineries for processing. This work requires a complementary focus on feedstock supply interfaces and logistics, as follows (http://apps1.eere.energy.gov).http://apps1.eere.energy.gov Interfaces: To develop compatibility at interfaces with commercial-scale handling equipment and conversion processes, R&D should explore biomass specifications and characteristics, the effects of various handling techniques, and the resulting impacts on conversion performance. Logistics: R&D is required for systems for harvesting, collecting, preprocessing, storing, and transporting diverse forms of biomass more efficiently. Therefore it is important to also research and develop equipment and systems to improve biomass quality, reduce costs, and increase productivity.

37 Africa has resources (material and human), but lacks productive action. Available technologies can be used to establish a vibrant bioenergy industry in Africa. Bioenergy is (probably) the only industry that can benefit all on sustainable basis. Economic empowerment from bioenergy industry, if well organised, can reduce conflicts and save the environment.
