Vietnam: Data from the Ministry of Industry and Trade indicates that the chemical and fertiliser sector is generating 1.4Mt/yr of phosphogypsum. It identified Dinh Vu DAP Plant in Hai Phong City, Lao Cai No. 2 DAP Plant and Duc Giang - Lao Cai DAP Plant as the three largest generators of the byproduct, according to the Sài Gòn Giải Phóng newspaper. The high volumes of phosphogypsum being created require large storage areas to be built. However, companies are facing issues expanding storage sites due to environmental regulations.
The Ministry of Construction has proposed establishing accounting regulations for phosphogypsum, ash and slag from fertiliser, chemical and thermoelectric plants. It is also promoting research into using ash, slag and gypsum as replacements for aggregate in road infrastructure projects.
