The paintings builds at the result of the COMPETE Bioenergy Competence Platform for Africa, which used to be supported through the ecu fee and coordinated by means of WIP Renewable Energies, Germany. The 5 sections disguise biomass construction and use, biomass applied sciences and markets in Africa, biomass regulations, sustainability, and fiscal and socio-economic matters. This precious paintings is, in influence, a single-source therapy of a key strength area in part of the realm which nonetheless has loads of unrealised capability for development.

2000). The fuel-stacking model is an important aspect to consider when designing and implementing policies to increase the use of improved traditional energy systems. 5 Conclusions The overwhelming majority of biomass used for energy in Sub-Saharan Africa consists of fuel-wood and charcoal that is burned in low-efficiency stoves for cooking, resulting in significant socio-economic, health, and environmental impacts. A number of alternatives exist to provide higher quality energy services at lower lifecycle costs and with significant reductions of negative impacts.

G. Forestry Stewardship Council – FSC). With respect to sustainability the main issues of concern addresses greenhouse gas balances, biodiversity, environment, food security, welfare of the community, and wellbeing of workers and of the local population (Fehrenbach et al. 2008; Royal Society 2008; Smeets 2008; Rutz et al. 2010). In order to ensure that biofuels are produced in a sustainable way, a number of countries are now introducing sustainability certification systems, whereby the buyers of biofuels ensure that their production complies with certain standards or sustainability criteria (Smeets 2008).

Traditional earth and earth mound kilns have an efficiency of 10–20%, depending on the skills of the charcoal producer and on the tree species. A skilled charcoal producer who uses well-dried wood can reach efficiencies of up to 30% (Wiskerke et al. 2008). Improved charcoal kilns can increase the efficiency of charcoal production to 45%, as well as enhancing the quality characteristics of charcoal. Whilst most of the low-cost improved charcoal kilns have demonstrated high efficiencies under test conditions, none of the developed designs have attained substantive dissemination, largely because of the surprisingly high efficiency of traditional kilns under field conditions.
