It meets the requirements of the control of waste water flowing into the Yangtze River, and effectively improves the environmental quality of the Yangtze River estuary.
The Chengbei sewage treatment plant project in Pizhou City, Jiangsu Province, constructed by China CAMCE Environmental Technology Co., Ltd. (CEETC), a subsidiary of Sinomach, boasts a service area of 39 square kilometers and a population of about 200,000 people, with an average daily sewage treatment capacity of more than 40,000 tons. It has been operating for over 10 years, and has played an important role in local energy conservation and emission reductions.
The Jiangbei comprehensive waste disposal center, constructed by the SUMEC, in Jiangsu Province, is the first domestic kitchen waste treatment project featuring a complete process system, advanced technology, and high resource utilization. The project’s processing capacity of kitchen waste, food waste, and waste cooking oil has hit 500 tons per day, 300 tons per day, and 50 tons per day, respectively.
The Foshan municipal domestic waste recycling treatment and quality improvement project in Guangdong Province, undertaken by China United Engineering Corporation Limited, a subsidiary of Sinomach, is an environmental protection science education base integrating industrial tourism, the circular economy, environmental protection demonstration, science education, and Party building education. The project is designed to process one million tons of domestic waste and 66,700 tons of municipal sludge annually, with an annual power generation of 517 million kilowatt-hours, and a cumulative reduction of 242,400 tons of carbon emissions.
The Xichang kitchen waste treatment project in Sichuan Province, undertaken by CEETC, a subsidiary of Sinomach, under the BOT (Build-Operate-Transfer) model, has improved kitchen waste treatment, ensuring waste is both harmless and recycled, reducing the overall volume of waste. Since it was put into operation, the project has processed more than 19,000 tons of kitchen waste per year, and reduced carbon emissions by about 17,000 tons annually, significantly alleviating the pollution caused by kitchen waste on the urban environment and local water systems.
The Changbai Mountain ecological protection and restoration project, undertaken by China IPPR International Engineering Co., Ltd., a subsidiary of Sinomach, aims for the conservation and restoration of mountains, rivers, forests, farmland, lakes and grasslands in the Changbai Mountains. Tackling comprehensive challenges involving extensive areas, difficult fields, multidisciplinary, and various specialties, the project fulfills 12 performance indicators such as river courses remediation and basin ecology restoration, increasing the area of local forests by 12.26 square kilometers.
The new energy-saving and environment-friendly R32 refrigerant key technology and air conditioning equipment industrialization project, implemented by Hefei General Machinery Research Institute Co., Ltd., a subsidiary of Sinomach, has made breakthroughs in key technologies such as thermodynamic cycle enhancement, safe and reliable application, and enhanced heat transfer with a small diameter. The project has developed a series of air conditioning equipment and related testing devices, promoted the full conversion of R22 air conditioning production lines to R32 air conditioning production lines, and has provided a Chinese solution to fulfill international conventions and promote pollution and carbon reduction in key industries.
