On November 10, a delegation of more than 20 people from Zibo Environmental Protection Century Tour organized by the Municipal People's Congress came to our company for a centralized interview on deepening the prevention and control of air pollution and consolidating the achievements of water environment governance. Song Yuanai, Secretary of the Party Leadership Group and Deputy Director of the Standing Committee of the District People's Congress, Zhao De, Deputy Director, Li Sen, Deputy District Head, and heads of relevant municipal and district departments accompanied the event.

The interview group listened to the report of the Chairman after visiting the reclaimed water reuse project of the Group. Dongjia Group has built a low-temperature waste heat recovery system and a back pressure power generation system in the new 300000 ton sulfur based sulphuric acid production project. The low-temperature waste heat recovery system will recover 200000 tons of steam on the basis of 400000 tons of steam produced by the main system. The back pressure power generation system can generate 48 million kilowatt hours of electricity annually, with significant energy conservation and economic benefits. The reclaimed water reuse project of the Group has entered the trial production stage, which plays a positive role in the water reuse rate and energy conservation and emission reduction through the Group. At the subsequent symposium, we listened to the presentations on environmental protection by the heads of relevant units.
