In 2024, the WHR system generated 69.6 million kWh of electricity, saving 121.7 billion VND in electricity costs. Additionally, the system supplied 25–30% of the total electricity demand for the entire plant, reduced exhaust temperature released into the environment, and indirectly reduced 86,000 tons of CO₂ by cutting dependency on power from thermal plants. It also reduced the input temperature for post-boiler processing stages, enhanced the operational stability of industrial fans, extended the lifespan and improved the efficiency of electrostatic dust filters, and contributed positively to business and production outcomes.

The WHR power generation system is a clean and green technology that reduces greenhouse gas emissions, decreases dust, and improves equipment efficiency. It is part of Vicem But Son's strategy of “Sustainable development, production in parallel with environmental protection, energy and resource efficiency,” following a circular economy model.

In addition to the WHR project, over the past five years, Vicem But Son has completed several other projects: converting electrostatic dust filters at the kiln and raw mill stages (DC1 and DC2) to baghouse filters; renewing license No. 337/QĐ-QLTN dated April 26, 1995, for the Hong Son limestone mine and Kha Phong clay mine; conducting supplementary exploration for associated mineral reserves, licensing extraction of limestone and associated minerals at the Hong Son mine; eliminating T-junction connections and installing a SCADA system for the 110kV But Son cement substation; as well as implementing various environmental protection measures. All projects have been executed on schedule and in compliance with legal regulations.

To continue improving production efficiency and ensuring employment and livelihoods for workers, the company is preparing to implement several new projects, including: projects involving clay mines in Lac Thuy District, Hoa Binh Province, currently undergoing legal procedures; and a project to increase the productivity of Cement Mill 2, which is in the process of investment approval.
