Workers spread substances to curb odours from garbage at Nam Sơn landfill in Hà Nội's Soc Son district (Photo: VNA) While officials say they are concerned about the growing mountain of trash,there are a number of new waste treatment centres close to beginningoperations.
And over the next 10 years, more high-tech landfill sites will be created.
The biggest site in Nam Son opened in 1999 and covers an area of 157 ha withfurther expansions planned over the next thirty years.
It receives around 5,000 tonnes of garbage each day, reaching 1.8 milliontonnes every year serving 12 inner districts and five suburbs of the capital.
This vast amount of rubbish has caused the authorities to look for alternativemeasures to solve the garbage problems.
Thien Y Hanoi Environment and Energy Joint Stocks Company were granted aninvestment licence to build a 7 trillion VND waste-to-energy plant at the Nam Son.
It was expected to handle 4,000 tonnes of garbage daily, generating about 75 MWper hour.
But construction of the new facility was delayed because of the COVID-19pandemic, according to the investor.
It now says it should be operational later this year.
Xuan Son landfill in Ba Vi district receives garbage from 12 suburban districtsof Ba Vi, Chuong My, Dan Phuong, Hoai Duc, My Duc, Phuc Tho, Phu Xuyen, QuocOai, Thach That, Thanh Oai, Thuong Tin, Ung Hoa and Son Tay town.
About 1,500 tonnes of garbage is transferred to the landfill daily, of which,1,400 tonnes is buried and the rest burnt.
Cau Dien landfill in Nam Tu Liem district mostly deals with medical waste andtoilet waste. Two other landfills in the city – Kieu Ki waste treatment area inGia Lam district and Phuong Dinh waste treatment area in Dan Phuong districthave both closed.
Solid waste is now gathered at Van Noi and Nguyen Khe dumps in Dong Anh districtand Vinh Quynh dump in Thanh Tri district. However, only the Nguyen Khe dump isnow able to get rid of a modest volume of waste.
Nguyen Huu Tien, Hanoi Urban Environment One Member Limited Company (URENCO)Director General, said overloaded landfills pose high risks of air pollution,wastewater leakage and garbage mounting up because it cannot be buried quickly.
He also fears the situation will worsen as the weather gets warming.
Tien said: “After Tet festival, the concentration of organic waste increasedwhile it’s wet and warm during spring, this caused difficulties to control thesmell discharged from the garbage.”
There were also issues with local residents who live near the plants angry overthe increasing amount of rubbish. Demonstrations at the site prevented trucksfrom entering and caused a huge garbage backlog.
But there is light at the end of the tunnel.
According to the Hanoi Construction Department, investment procedures of threewaste-to-power projects in the city are being completed.
The three projects are in Son Tay town and Ba Vi district and can handle an extra3,000 tonnes of garbage each day.
In Viet Hung commune, Dong Anh district, an industrial waste depot is almostcomplete, but investors are asking for permission to treat medical waste aswell as industrial waste.
If Government approves their proposal, the plant would start operating in July,a representative of the Viet Hung plant said.
Nguyen Truc Anh, Director of the municipal Planning and Architecture Departmentsaid that by 2030, Hanoi plans to have 17 waste treatment areas.
The municipal authorities were stepping up land clearance to make room forwaste treatment projects and called for investment including Chau Can in PhuXuyen district, Phu Dong in Gia Lam district, Dong Ke, Nui Thoong in Chuong Mydistrict, Dong Lo in Ung Hoa district, Lai Thuong in Thach That district and HopThanh in My Duc district.
The waste treatment areas ranged from 4 ha to 20 ha with the capacity of500-1,200 tonnes of garbage daily.
Anh said: “Under the plans, more waste treatment plants would be built in HàNội to help reduce the distance from the places where garbage is gathered tothe places where the garbage is treated.
“The distance is about 10-30 km, so garbage would not be carried throughinner-city areas.”
Nguyen Trong Dong, Vice Chairman of the Hanoi People’s Committee said the cityasked relevant agencies to help solve difficulties for waste-to-energy plantprojects.
Authorities in districts of Soc Son, Ba Vi, Son Tay town and other districtswith waste treatment projects were asked to speed up land clearance to makeroom for the projects, Dong said.
He added: “With such a huge amount and increase in volume of garbage, Hanoi identifiedtwo key solutions to the issue.”
While the city is looking for investors who can incorporate modern technologyin their waste control methods, they are also asking the public to ensure theycategorise garbage at source and work together to improve waste management forfuture generations./.
