At the meeting, GIZ-Nexus reported the results of their inspection visit to the Khanh Son Landfill, and introduced to the related agencies two methods of improving the quality of solid waste management in Da Nang city, including thermal treatment with upstream dewatering and mechanical biological treatment.
In specific, thermal treatment with upstream dewatering will take from 24 to 28 months for construction at a cost of $100 million. However, once finished, the plant can operate with a capacity of 365,000 tonnes per year, generating up to 91,000 mWh of renewable energy per year and with a waste handling fee of $25 per tonne for collection. Meanwhile, after completion, the mechanical biological treatment project can operate with a capacity of 335,000 tonnes per year, producing 210 tonnes of RDF per day for cement kilns, paper mills and thermal power stations. This project can generate up to 110,000 kWh of electricity per day with a source of profit of $22 per tonne for waste management fee. According to GIZ-Nexus experts, in terms of technology, both methods are environmentally friendly, the liquid waste of the projects is up to the TCVN 5945 2010 standard.
After listening to the report by the project team to improve solid waste management in Da Nang, Vice Chairman Nguyen Ngoc Tuan highly appreciated the results of the study and stressed that Da Nang was very concerned about environmental issues, especially wastewater and solid waste. Therefore, the city leaders and related departments will seriously study the two treatment methods suggested by GIZ-Nexus. The vice chairman hope in GIZ-Nexus' coming report, which is supposed to be submitted to the city leaders in July 2017, the team can advise on the better option between the two methods for the city to choose from.
