Cost structure of charcoal Blantyre and Lilongwe FROM: Kambewa P. etal. 2007. Charcoal: the reality - A study of charcoal

consumption, trade and production in Malawi. pubs.iied.org/pubs/pdfs/13544IIED.pdf.

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.

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)

Feedstock Supply and LogisticsFeedstock Supply and LogisticsFeedstock Supply and LogisticsFeedstock 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)Feedstock Supply and Logistics (continued)Feedstock Supply and Logistics (continued)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).

• 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.

CONCLUSIONS

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.
