Abstract
Semi-aerobic system holds greater advantages when compared to anaerobic landfill because of the reduction of environmental impacts through purification of leachate, which accelerate waste stabilization, among other things. In addition, there are less construction costs and maintenance is easier. Due to these advantages, we had some application this system in overseas such as Malaysia, China, Iran, Samoa, Italy etc. However, the landfill design and operation in overseas is dependent upon the responsibility of the recipient country. It is therefore important for the transfer of semi-aerobic system to oversea that the concept for this system is well understood and an efficient system set in place. The effects of this system on reducing environmental risks must also consist of methane gas reduction, etc. Investigation into this issue must be continued in order to collect more scientific data and detailed mechanisms must be taken into consideration before semi-aerobic system is recognized as one of the co-benefit CDM technology and eventually introduced on a global scale.
