from Part III - Biochar Production
Published online by Cambridge University Press: 01 December 2016
The majority of the rural population in Cambodia, Lao PDR and Thailand is forest dependent. Biomass fuel, predominantly fuelwood and charcoal, is the main source of energy for cooking and heating in households, especially in rural areas. Traditional and simple methods to produce charcoal in combination with a range of different feedstocks leads to a wide range of achievable product qualities, production efficiencies and health risks due to emissions. Improvement in charcoal production techniques is therefore increasingly promoted. Utilization of co-products, such as pyroligneous acid, can be beneficial in agricultural and livestock production, for example as insecticides, antimicrobial agents and insect repellents. However, it is necessary to use them in a proper way, therefore more research and ultimately education of farmers and smallholders is needed, along with a robust quality assurance scheme. Moreover, waste from charcoal production such as charcoal dust or chunks of broken charcoal pieces can be used as biochar to improve soil properties. By increasing soil productivity and fertilizer efficiency, the region may contribute to climate change mitigation and sustainable development. This chapter gives an overview of traditional and improved kiln technologies and their characteristics, and potentials for biochar production and byproduct utilization are discussed in detail.
