Abstract—Quantification and characterization of municipal solid waste are vital information for a proper solid waste management. However, these are under-investigated and scarcely implemented in Laos PDR, especially the local communities. This work, therefore, aimed to quantify and characterize municipal solid waste generated from Beung Kiat Ngong Ramsar Site and to recommend possible integrated solid waste management strategies for a sustainable waste management. The average daily waste generation was estimated to be 3.6 kg/day and 2.6 kg/day in Thabou village and Kiat Ngong village, respectively. Organic waste appeared to be the biggest component (28%) for Thabou village, while packaging’s dominated waste composition in Kiat Ngong village. Interestingly, high percentage of golden apple shells waste were mismanaged. These had the potential to convert into value-added products such as calcium carbonate (CaCO3). It was found that fresh golden apple shells contained only 24.16±0.48 g/l as CaCO3, while incineration method increased higher CaCO3 products. The result showed that incineration at the temperature of 400 oC gave the highest amount of CaCO3 with the values of 1207.67±9.45 g/l as CaCO3. Based on the resources and the strength of the Ramsar site, the production of value added material from bio-waste could be integrated into waste management strategies along with 3Rs policies implementation.
Index Terms—Beung Kiat Ngong Ramsar site (BKN), solid waste management, golden apple snail shells (GAS), calcium carbonate (CaCO3).
