บทคัดย่อ (EN): The economy of the Lao Peoples Democratic Republic (PDR) has relied substantially on natural resources, especially timber. With the expansion of the economy, forests are continuously depleted to meet industrial demands for wood products. In Khammouane province, where many wood processing industries are located, one of the problems is the pollution of the environment through sawdust disposal. Meanwhile, all of the communities who inhabit this area use wood charcoal as a main source of fuel. However, the suitability of the wood charcoal for cooking has not been fully determined. This study examines the conversion of sawdust to briquette charcoal as one of the alternative utilizations of sawdust dumping. This research aimed to study this utilization of sawdust into briquette charcoal production by determining the quantity of sawdust produced from timber processing, investigating the briquette and wood charcoal consumption in this province, and comparing the physical and chemical characteristics of briquette and wood charcoal. Six different wood charcoal specimens from six different wood species were taken, namely Cratoxylum cochinchinense, Pterocarpus marcocapus, Pinus merkusii, Sindora siamensis, Ketepeleeria davidiana and Pettophorum dasylachis. In addition, one specimen of sawdust briquette charcoal was collected and taken to the laboratory to determine the physical properties (gross calorific value) and the chemical properties (moisture, volatile, ash and fixed carbon content). Results show that there was a total sawdust generation of approximately 6,100, 8,204 and 4,763 metric tonnes in 2005, 2006 and 2007, respectively, while the average proportion of charcoal consumption per capita was estimated to be approximately 0.072 kg/capita/day of briquette charcoal and 0.072 kg/capita/day of wood charcoal. Also sawdust briquette charcoal was found to be a quality charcoal in terms of high gross calorific value at 7,595 cal/g and high fixed carbon of 78.68%. Nevertheless, sawdust briquette charcoal had low moisture and ash contents of 1.88% and 3.79%, respectively, compared to wood charcoal. Results from this research conclude that sawdust briquette charcoal is an alternative source of household cooking fuel. Therefore, the conversion of sawdust into briquette charcoal production is likely the most appropriate approach for sawdust utilization in Khammouane province.
