Amid greater efforts by China to achieve its dual-carbon goals, enterprises in Jinjiang, a county-level city in Fujian province, are banking on innovation to alleviate pollution and reduce carbon emissions, focusing on textile printing and dyeing industries with high energy and water consumption.

A factory of Fujian Fynex Textile Science and Technology Co, located in the Jinjiang economic development zone, has put in place intelligent printing and dyeing equipment to treat sewage, recycle and purify waste gas, and recover waste heat.

The company's 36,000-square-meter rooftop solar photovoltaic system generates about 5 million kilowatt-hours of electricity annually. Wastewater treatment systems with new technologies allow for more than 50 percent reuse of sewage. Four sets of flue gas recycling equipment for efficient recycling and purification of exhaust gas and waste heat recovery can save 5,000 metric tons of standard coal per year.

"With a set of combined technologies, our comprehensive energy consumption has been reduced by more than 20 percent," said Ye Weigang, administrative director of Fynex.

The company has introduced sewage treatment technology to improve the effect of sewage treatment, reduce its cost and achieve sewage treatment indexes that are comprehensively better than the national emission standards, said Ban Qiyong, director of the Fynex sewage treatment plant.

Through structural adjustment, policy encouragement, innovative mechanisms, scientific and technological innovation and application, Jinjiang has achieved certain results in reducing pollution and carbon emissions.

This has stimulated new momentum among enterprises in Jinjiang, of which 122 have introduced clean production technologies and efficient end-of-line treatment equipment to achieve systematic green upgrading of the whole process.

Nineteen enterprises, such as sportswear brand 361 Degrees International Ltd and Hengan Group, have been designated as national green factories, which provide valuable experience and reference in reducing pollution and carbon emissions.

"Through the construction of green factories, our company's entire production supply chain runs smoothly," said Hou Chaohui, vice-president of 361 Degrees.

The idea of green development within enterprises is now becoming more popular and it is hoped that other enterprises will act together to build green industries, Hou said.

"The concepts of green, low-carbon and sustainable development always run through the whole process of Hengan Group's production," said Wang Xiangyang, vice-president of Hengan.

Wang said that Hengan's development follows the strategy of green and sustainable development, pursuing social, ecological and economic benefits.

Looking ahead, Jinjiang economic development zone said it will continue to cater to the dual-carbon goals and improve the park's green construction, striving to build a green, smart and innovative modern park.

The economic development zone is trying to create a zero-carbon park and cultivate more green and low-carbon factories, it added.
