Alterations will be made to packages three and four of the civic body's four-part (each called a package) 1,442-crore solid waste management revamp plan, which TOI reported in June. According to the initial proposal, the city's landfill sites at Perungudi and Kodungaiyur would be shut and, in its place, the civic body would set up two waste-to-energy incinerator plants.

About 6,000 tons of solid waste (click here) is produced daily in Hanoi, 95 percent of which is buried, according to the city’s construction department.
Hanoi authorities have called on enterprises to invest in technologies to treat and recycle waste to turn waste into useful materials.
Nguyen Phuc Thanh, general director of Enserco, said his company has a patent for technology to treat domestic waste by burning with heat recovery.
The technology reduces waste treatment costs as it uses less supporting fuel because it removes garbage components that cannot be burned and dries garbage to reduce humidity before burning.
During the waste burning process, the heat from the incinerator emissions is used to dry garbage and heat the air provided to the incinerator. When sorting and drying garbage, workers use equipment to collect gas in the incinerator in order to reduce the discharge of bad odors into the environment.
Enserco’s waste treatment plant in Son Tay can treat 700 tons of waste a day.
