(VEN) - The Vietnamese mining industry has made significant contributions to the country’s socioeconomic development. However the industry has had a negative impact on the environment. To reduce this, coal companies, especially the Vinacomin-Nui Beo Coal Joint Stock Company have made greater efforts to control pollution as part of moves to preserve the environment.
The company has promoted investment in wastewater treatment systems
The company’s mine sites and dumping grounds are located near to residential areas in Ha Long City. Therefore, the company has implemented many solutions to reduce pollution such as classifying kinds of wastes and building wastewater drainage systems. In particular, neighboring company offices and workshops have been surrounded with 64.5 hectares of trees.
Dust and harmful gases are unavoidable in the mining. Therefore, the company implements water sprayer activities three times a day in order to reduce dust. The company has invested in purchasing road cleaning trucks.
To deal with dangerous wastes, the Nui Beo Coal JSC has developed a strict management system. The company has built eight basins containing water polluted by oil in order to collect oil film and 11 dangerous waste storages facilities. In addition, the company has signed contracts to transport and deal with dangerous wastes with environmental firms.
The public has complained about wastewater treatment activities at mines. Therefore, the company has invested in a 1,200 cubic meter per day system to handle wastewater. All wastewater meets environmental standards. Half of the clean water is used its water for road cleaning, water spraying for dust reduction and car washing.
The Nui Beo Coal JSC has also worked with the Japan International Cooperation Agency following support from the Quang Ninh Department of Natural Resources and Environment and Department of Agriculture and Rural Development to pilot the growing of 100 Jatropha trees at the northeast mine site, marking a major step forward in environmental restoration activities in Quang Ninh Province.
The Japan International Cooperation Agency is also supporting the company to pilot the planting of Jatropha trees on three hectares at the northern dumping ground.
