Abstract
The waste hierarchy refers to the "3Rs" reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization. Finally non-usable wastes go to the landfill. In developed countries, landfilled waste amount has been decreased and the importance of prevention, material recycling has been growing.
However, realistic priority for supporting waste management in developing countries has shown in reverse. In many countries in Southeast Asia, technical improvement of landfill is the most urgent issue. Besides, increasing waste amount in developing countries is also main problem because the usable capacity for landfill is limited by the public resistance and environmental contamination. For reducing the disposed waste amount, there are two concepts of material recycling and energy recovery. As growing energy supply issue in Southeast Asia, this study is aimed to explore the item to solve both energy supply and reduction of waste amount by waste-to-energy technologies.
It has been reported that deforestation problem by indiscriminate logging for cooking fuel or energy source in industrial part. In this study, we will discuss appropriate technologies for achievement of energy supply and global warming problem based on our site visiting in Cambodia.
