Through relentless technology innovation and equipment upgrading, Yingyang Group strives on reducing emission and lowering energy consumption from the source. Replaced all water-ring vacuum pumps with screw-drive vacuum pumps on all distillation units, reducing waste water discharge by 300 MT per year.The recovered-heat boiler that is attached to our solid-waste incinerator will offer a saving of one million cubic meters (1 MM3) of NG per year.Recycling and reusing the steam condensate maximize heat-recycling.  By doing so, Yinghai CZ will save 1.6 million cubic meters (MM3) on NG per year, and SD Yingyang will save 0.9 MM3 on NG per year. An MVR energy-saving system in Yinghai CZ has commissioned and it will save 26,000 MT on steam per year, equivalent to a savings of 3 MM3 on NG.Both Yinghai CZ and SD Yingyang maximized on using solar energy for plant lighting and generating domestic hot-water.We continued to improve our production facilities and equipment to be Large-scaled, Sealed, and Automated, in order to eliminate material leaks and gas escapes.Energy consumptions are monitored on-line, KPIs are set for Energy Conservation and Process Control.We passed the ISO14001 certification, systematically and scientifically balance enterprise development and ecological environment.
