Quang Ninh (VNS/VNA) - Going green withconstruction work, TKV, a unit of Vietnam Coal and Mineral Industries Group(Vinacomin), started recovering its mine waste with soil and rock for levellingof civil and industrial works at Suoi Lai mine in Quang Ninh province recently.

Director of Quang Ninh Coal Processing Company - TKV Ngo Xuan Truongsaid: "The use of waste rock will contribute to reducing the height andarea occupied by the waste dumps and reduce exploitation and use of naturalhills, minimise negative impacts on landscape and environment."

The transformation is consistent with the economic transformationmodel from brown to green in Quang Ninh province and developing sustainablyaccording to the circular economy model.

After the end of land and rock recovery from the waste dumps,cleaner land will allow for infrastructure and industrial parks to be builtaccording to the province's traditional model of the coal industry.

Vinacomin has assigned TKV to plan areas for waste soil and rockfrom coal mining and processing that can be used as sanding materials, groundlevelling, building materials, and using and trading waste soil and rock afterobtaining the permission of the State and local management agencies.

The company has signed economic contracts to provide land andwaste rock for projects, including Cua Luc 3 Bridge and Coal Industry UrbanArea. It continues to negotiate signs with project owners/contractors.

The demand for building materials for civil, industrial, serviceand tourism projects increased. In the period from 2021 to 2025, the demand forlevelling materials to develop the land fund for the socio-economic developmentof registered projects was about 640 million cu.m in the local area. By 2030,the demand for levelling materials for registered projects will be about 1.02billion cu.m.

From the process of mining coal by the open-pit method fordecades, excavated and waste soil and rock have been dumped into landfills atmore than 1 billion cu.m with a very large area of land.

Currently, an annual amount of soil and rock excavated and dumpedmore than 150 million cu.m, partly to fill in the mining pits, improve thewaste layers, and improve and restore the environment.

Earlier, the Ministry of Natural Resources and Environment agreedin principle to allow the Vietnam Coal-Mineral Industry Group to recover anduse wasteland and rock from the waste dump during coal mining at Suoi Lại mineto as levelling materials for construction projects in Quang Ninh province atthe total volume of3.5 million cu.m. The implementation period was until theend of this year.

The group was asking MoNRE for an extension until the end of 2025./.
