Solid waste treatment remains questionable

VietNamNet Bridge – In 2017, up to 38,000 tonnes of municipal waste is generated a day in Vietnam and a lack of proper solutions to the waste problem is harming the urban environment.

A group of specialists, including Le Hoang Anh, Mac Thi Minh Tra and Nguyen Thi Bich Loan, from the Northern Centre for Environmental Monitoring Portal under the Viet Nam Environment Administration discovered municipal solid waste in the country increases 10 to 16 per cent each year.

Hanoi, HCM City, Da Nang and Hai Phong account for 45.24 per cent of solid waste generated by urban areas.

Up to 70 per cent of municipal solid waste is household waste.

Plastic waste makes up 7 per cent of solid waste, about 2,400 tonnes a day.

Up to 95 per cent of plastic waste in Hanoi, however, is buried. The percentage in HCM City is 76 per cent.

Although the percentage of collected waste has increased in recent years, it has still remained low due to the growing speed of waste generation, poor treatment capacity and low awareness of people, especially in rural areas.

Seventy six million tonnes of straw and 47 million tonnes of poultry litter are generated annually, of which up to 70 per cent is discharged directly into rivers and irrigation systems.

Industrial waste, construction waste and medical waste also require effective treatment to prevent pollution and diseases from spreading.

Waste sorting is considered a simple yet efficient solution for the country’s rapid solid waste generation rates.

Hanoi, Da Nang City and HCM City have piloted waste sorting projects recently.

From November 24 last year, HCM City authorities started enforcing regulations on garbage classifying, imposing a fine of up to VNĐ20 million (US$860) for each violation.

The Ministry of Construction has acknowledged five solid waste treatment technologies including two composting methods, refuse-derived fuel and two incineration methods.

Among 660 landfills in Vietnam, only 203 dumps meet sanitation requirements.

Nguyen Duc Quyen, lecture of the School of Heat Engineering and Refrigeration under Ha Noi University of Science and Technology, said waste treatment technology in Vietnam is developed mostly by individuals and private companies.

Therefore, he recommended encouraging scientists and experts in this field to improve the efficiency of garbage collecting, sorting and treatment in Vietnam.

HCM City and Hanoi spend about VND1.5 trillion ($64.5 million) a year on processing garbage, accounting for 3.5 per cent of the cities’ public budgets.

The cost for other provinces is estimated at to VND40 billion ($1.72 million) a year.

The sanitary charge of VND4,000 to 6,000 (17 - 25 cents), paid monthly to a local environment company, only covers 20 per cent of waste collecting and transporting expenses.

Therefore, pricing for municipal waste, especially household waste treatment, can both reduce garbage and increase investment in new technologies, experts recommended.

Nguyen Thuong Hien, head of Waste Management Administration stressed the importance of tightening monitoring mechanisms for garbage sorting and investing in efficient waste treatment technologies.

The Ministry of Natural Resources and Environment also plans to impose service charges on municipal waste treatment by 2025, initially in large cities.
