An Overview of Biochar Production and Biochar Producing Stoves in Bangladesh

Abstract

Biochar is not a newly invented technology; rather its relevance and efficacy have recently come to the front burner. Naturally, it is deposited in the soil through forest and grassland fires. Interestingly, biochar is also produced from biomass by zero or low oxygen environment. However, biochar has gained an international research interest and offers ample scope for further investigations on biochar and biochar producing cooking stove. The present review paper mainly focuses on the status of biochar production and biochar producing stoves with specific emphasis on the status of biochar production technology and the perception, knowledge, and attitude towards biochar production and utilization; use and performance of biochar producing cooking stoves; and problems encountered in biochar production and utilization. Having observed positive perception, and attitude as well as an appreciable knowledge of rural farmers in biochar production and utilization the paper emphasizes the incorporation of a policy framework, training and enhanced access to information for higher agriculture use of biochar and sustainable environment.
