Biochar Production from Agricultural Waste in Amphawa District, Samutsongkram Province Thailand

Article Preview

Abstract:

Agricultural waste is environmental problem in Amphawa district. Therefore, Biochar is the alternative choice of waste minimization from agricultural waste. This research was aimed to produce biochar by pyrolysis method and characterize the biochar obtained under different raw materials. Branches of pomelo trees, lychee trees, coconut shells and pomelo pulps and the aquatic weed were used raw material for biochar production. The bio char had high carbon at above 70% w/w all of samples. Potassium concentration of pomelo branches and water hyacinth was 1.85 and 1.048 mg/kg, respectively. Surface area of biochar product from Branch of lychee tree was highest at 253 m2/g.The ratio of 1:1 bio char with organic fertilizers is highest plant growth rate.
