Lao People’s Democratic Republic (Lao PDR) is a land-locked developing country in Southeast Asia. The total area of the country is 236,800 km2. The total population as of 2017 was 6.8 million (World Bank 2019). Since the last two decades, the economy of Lao PDR has been growing significantly. Economic growth, population increase, rapid urbanization, and changing lifestyle are major contributions to growing environmental problems, especially solid wastes. In Vientiane Capital, wastes are generated approximately 650 tons per day, and only half of them are collected and disposed of properly in the landfill (VCOMS 2018). The same situation can be seen in secondary provinces, such as Luang Prabang, Savannakhet, Champassak, and other provinces across the country.
