A cassava starch processing factory, run by Taiwanese company Vedan in the north-central province of Ha Tinh, has been shut down after inspectors found it was polluting the Rao Tro river.

Inspections on April 1 found Vedan was discharging untreated wastewater directly into the local river.

Inspectors say the factory was causing severe environmental pollution because it has not built a proper wastewater treatment system; there were leaks in one of two wastewater storage pools pouring into Rao Tro river, diesel oil in cassava drying facilities were leaking out into the river; a mixture of rainwater and wastewater from over 50 tonnes of cassava waste gathered in outdoor storage areas was flowing into a drain leading to the river.

Phan Thang Long, deputy director of the province’s Department of Natural Resources and Environment, said the factory has been asked to close down until it corrects these four violations.

Truong Vinh Chu, director of the factory, has admitted to the charges and committed to install the factory’s wastewater treatment systems before July.

The Taiwanese-invested factory plans to officially begin operating in November, with a capacity of 800 tonnes of cassava starch per day.

Vedan has already gained notoriety as a river polluter. Its MSG-plant in the southern province of Dong Nai was recently found using underground pipes to dump untreated wastewater into the Thi Vai river for more than 15 years./.
