Tonglu Red Lion was awarded A-level performance of air pollution prevention and control, and many enterprises of the Group were awarded national green certification.

Recently, Tonglu Red Lion was successfully awarded the A-level enterprise of air pollution prevention and control performance in cement industry, which is the highest authoritative rating of air pollution control in the industry. The A-level performance of

air pollution prevention and control represents that the ultra-low emission of the whole chain of enterprises meets the top standards of the industry, covering the whole dimensions of organized, unorganized emissions, clean transportation and digital management and control. As the group's first enterprise to complete the whole process of ultra-low emissions and through industry publicity, Tonglu Red Lion focuses on green quality improvement, with a total investment of about 42 million yuan to carry out systematic environmental upgrading. The Company iterated the denitrification system, renovated the sewage outlets, upgraded the intelligent monitoring equipment, completed the closed transformation of the raw material storage shed and the material corridor, and equipped with dust suppression facilities such as spray dust suppression and automatic car washing. The Company also established an intelligent environmental management and control platform to achieve data traceability and closed-loop supervision of the whole process of raw materials entering the factory, production and processing, and finished products transportation, and fully met the ultra-low emission standards of the industry. After

The mine strictly implements the principle of "mining while restoring", optimizes mining technology, improves soil and water conservation, promotes reclamation and greening of mining areas, and realizes the coordinated development of mineral development and ecological protection. Relying on the construction of national green factories, the production side continuously optimizes the production process, improves the energy utilization rate, disposes of industrial solid waste on a large scale, builds an intelligent energy-saving system, greatly reduces production energy consumption and pollutant emissions, and walks out of a green development road with win-win economic, ecological and social benefits.

In the next step, Red Lion Group will take the national green certification as a new starting point, continue to deepen the construction of ultra-low emission, green mines and green factories, realize the full coverage of green development of the whole chain of mines and production, and enable the sustainable development of enterprises with green and low carbon.
