Abstract

The paper presents results of rice straw biomass potential and applying efficiency for household scale biochar production in Tien Giang, a typical case study in Go Cong Tay district. The study results showed that the total rice production of Go Cong Tay district was 185.072 tons/year and the rice straw biomass corresponding 233.190,72 tons/year. This rice straw biomass have the high organic ingredients and calorific value, about 44,1% ratio and 4.030 kcal/kg respectively. With weigh 100 kg of input rice straw, the biochar obtained 48,25 ± 2,25 kg (48,25%) after 6 hours burning. The volume of ash and unripe coal ratio were quite low equal to 0,75 ± 0,13 kg and 3,95 ± 1,33 kg, respectively. Optimizational biochar production have short burning process with highly biochar products weight, low ash and unripe coal contents. In addition, the organic ingredients and calorific value from biochar products meet the quality requirements for purposes such as land reclamation, increasing crop yield and towards sustainable agriculture.
