Since its operation in 2007, the Khanh Son landfill site in Hoa Khanh Nam Ward, Lien Chieu District, Da Nang, has been an urban solid waste treatment facility with sanitary landfill technology.

After more than 10 years of operation, the landfill site has received more than 3.2 million m³ of waste.

Over recent years, the landfill has been emerging as one of the city’s environmental pollution hotspots, adversely affecting the health of the local residents as well as their daily lives.

The city is now facing challenges in dealing with the large volume of untreated solid waste. It is reported that, every day, between 850 and 900 tonnes of solid waste are collected from across the city and buried at the landfill.

The Khanh Son landfill site is expected to be full by May 2020, and its working life is likely to end no later than 2021.

Although the municipal authorities and Although the city government and the local Urban Environment Company have taken numerous measures, the problem has yet to be resolved completely.

The Khanh Son landfill will be upgraded into an ecological solid waste treatment complex

Director of the city’s Department of Natural Resources and the Environment To Van Hung remarked the municipal authorities are planning to upgrade the Khanh Son landfill into an ecological solid waste treatment complex in the coming time. The intention is to help the city deal with overloaded dumps and environmental pollution there.

The focus will be on building leachate collection system to ensure its synchronous operation with the 2^nd stage of the leachate treatment plant having a daily treatment capacity of 1,050m³.

Besides, waste burial areas Nos 6 and 7 will be constructed to minimise the possibility of dispersing odour from newly-buried garbage.

The landfill will be covered with canvas sheets, just leaving an area of 2,000m² to dump the rubbish.

Also, an energy-from-waste incinerator, with a daily treatment capacity of 1,000 tonnes of trash, a medical and industrial waste incinerator, and a qualified sludge treatment system, will be built at the Khanh Son landfill.
