As part of the project which is under JICA’s partnership program, in June 2015, Fukuoka Prefectural Government has collaborated with Hanoi to complete the construction of a pilot model on landfill cell using semi-aerobic sanitary landfill technology known as Fukuoka method, in Xuan Son commune. This waste disposal method enhances the decomposition of waste by installing pipes under the ground of the landfill and activating micro-organisms in the soil.
Thanks to the method, waste is decomposed under semi-aerobic circumstances, and waste layers sink deeper compared to other traditional landfill (anaerobic) dumped at the same time. Accordingly, land filling will last longer. Besides, compared to completely open land filling (waste is just dumped without processing), Fukuoka method almost liberates landfills from their typical foul odor.
With the basis of waste treatment techniques and experiences in the project, Fukuoka method is synthesized and compiled as “Guidelines for construction of Fukuoka method landfills in Hanoi” for future landfill construction tailored to the particulars of Hanoi.
This document is expected to show its effectiveness when being applied to construction of new sanitary land fill sites” while experiences gained from the project will be widely disseminated to other cities and provinces in the country.
Rapid economic growth, population growth in the city and lifestyle changes have increased consumption of Hanoi, thereby leading to annual increase in the amount of waste and changes in waste quality. In this context, the lack of sanitary landfill sites has caused a serious problem for the capital.
Besides, environmental sanitation and other problems for the public places such as odor and waste water discharge due to inappropriate treatment, indiscipline rubbish dumping … have been headache issues./.
