A group of specialists, including Le Hoang Anh, Mac Thi Minh Tra and Nguyen ThiBich Loan, from the Northern Centre for Environmental Monitoring Portal underthe Vietnam Environment Administration discovered municipal solid waste in thecountry increases 10 to 16 percent each year.
Hanoi, HCM City, Da Nang and Hai Phongaccount for 45.24 percent of solid waste generated by urban areas.
Up to 70 percent of municipal solid waste is household waste.
Plastic waste makes up 7 percent of solid waste, about 2,400 tonnes a day.
Up to 95 percent of plastic waste in Hanoi, however, is buried. The percentagein HCM City is 76 percent.
Although the percentage of collected waste has increased in recent years, ithas still remained low due to the growing speed of waste generation, poortreatment capacity and low awareness of people, especially in rural areas.
Seventy six million tonnes of straw and 47 million tonnes of poultry litter aregenerated annually, of which up to 70 percent is discharged directly intorivers and irrigation systems.
Industrial waste, construction waste and medical waste also require effectivetreatment to prevent pollution and diseases from spreading.
Waste sorting is considered a simple yet efficient solution for the country’srapid 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 regulationson garbage classifying, imposing a fine of up to 20 million VND (860 USD) foreach violation.
The Ministry of Construction has acknowledged five solid waste treatmenttechnologies including two composting methods, refuse-derived fuel and twoincineration methods.
Among 660 landfills in Vietnam, only 203 dumps meet sanitation requirements.
Nguyen Duc Quyen, lecture of the School of Heat Engineering and Refrigerationunder the Hanoi University of Science and Technology, said waste treatmenttechnology in Vietnam is developed mostly by individuals and private companies.
Therefore, he recommended encouraging scientists and experts in this fieldto improve the efficiency of garbage collecting, sorting and treatment inVietnam.
HCM City and Hanoi spend about 1.5 trillion VND (64.5 million USD) a year onprocessing garbage, accounting for 3.5 percent of the cities’ public budgets.
The cost for other provinces is estimated at 40 billion VND (1.72 million USD)a year.
The sanitary charge of 4,000 to 6,000 VND (17 - 25 cents), paid monthly to alocal environment company, only covers 20 percent of waste collecting andtransporting expenses.
Therefore, pricing for municipal waste, especially household waste treatment,can both reduce garbage and increase investment in new technologies, expertsrecommended.
Nguyen Thuong Hien, head of the Waste Management Administration, stressed theimportance of tightening monitoring mechanisms for garbage sorting andinvesting in efficient waste treatment technologies.
The Ministry of Natural Resources and Environment also plans to impose servicecharges on municipal waste treatment by 2025, initially in largecities.-VNS/VNA
