Vietnamese hospitals dump more than 30 tons of hazardous solid waste, or a quarter of the untreated medical solid waste discharged every day, according to the Ministry of Health.
The ministry said at a conference Wednesday that only around 73 percent of hospitals in the country use incinerators to process hazardous wastes.
The rest resort to burning the waste outdoors or burying it in their premises or in local garbage dumps.
According to the ministry, more than half of hospitals also fail to meet environmental standards for storing medical waste.
It estimated the volume of medical solid waste discharged daily to reach 800 tons by 2020.
