| Abstract | The study was aimed to assess the use of biomass and its application in Battambang province of Cambodia. Specifically, the research estimated the availability of biomass resources within the province, characteristics of fuels used and efficiency of cookstoves, and the use of traditional and improved cookstoves in the province. Estimation of biornass resource availability in the province indicates that there is about 1,308 TJ per year from agricultural residues, while from forest residues it is 1.42 TJ per year and about 197 TJ per year from animal wastes. A survey was conducted in 95 households to find the energy sources used for cooking. The results indicate that 80% of households use fuel wood, 14.74% use charcoal and the rest use other biomass, LPG and kerosene. Amongst the households using fuclwood, most respondents (89.5%) collect fuelwood and only 10.5% purchase fuelwood. The fuel consumption in household was 120 kg of fuelwood or 75 kg of charcoal or 10kg of LPG per month. The household's expenditure for purchasing fuelwood, charcoal and LPG is estimated to be about 20,000 riel, 30,000 riel and 33,600 ricl per month respectively. The survey also found that two cookstove types were used: traditional cookstove (74%) and improved cookstoves. The traditional lao bucket stove was used by 63% of the respondents. Experiments carried out to estimate the efficiency of fuelwood (fuel) showed that traditional stove gave an efficiency of 12.18 to 15.86%, while improved cookstove gave efficiency ranging from 16.43 to 22.96%. Charcoal (traditional) cookstoves gave an efficiency of 21.34 to 22.37%, and improved cookstoves from 23.72 % to 29.82%. A study on use of cookstoves in Battambang province was conducted to find the specific daily fuel consumption and the fuel savings. Cookstoves using charcoal could save 2.79 kg to 3.54 kg per household per day and cookstoves using fuelwood could save 5.13 kg to 6.38 kg per household per day. Improved cookstove (NLBS) can save 338 kg per year charcoal as compared with traditional cookstove (TLBS) or about 135,200 riel per year per household. The payback period of improved cookstoves is estimated at about a month (33 days) |
