IE expo Chengdu 2023: breakthrough in industrial concept, technology and ecosphere

On July 14, 2023, with the strong support of all parties, the 4th edition of West China’s Leading Environmental Trade Fair—IE expo Chengdu 2023—concluded successfully at the Western China International Expo City. After a two-year hiatus, 449 exhibitors gathered in the western region, attracting over 32,000 trade visitors. The three-day event served as a platform for exploring cutting-edge technologies and development trends in the industry.

Upgraded concept of “Environmental Protection” to build “big environmental protection” ecosystem in the Central and Western China

Since 2021, the concept of "Environmental Protection” has evolved to include not only traditional environmental governance and pollution reduction but also the mission of carbon reduction in green and low-carbon areas. As the flagship industry platform in Central and Western China, IE expo Chengdu 2023 has adapted to these evolving needs. While maintaining a focus on pollution end treatment, this year's event also extended its scope to include energy conservation, emission reduction, carbon reduction, recycling, and other related areas. The exhibition scale has increased by a steady 16.6 % compared to the previous edition, covering approximately 40,000 square meters. IE expo Chengdu 2023 actively created a “big environmental protection” ecosystem, providing solid support for green, low-carbon, and high-quality development.

Technology-based enterprises shine brightly in Central and Western China

In the critical period of improving the quality of the ecological environment, the environmental protection industry technology needs to focus on improving quality and efficiency, technology coupling, and system collaboration to provide technical support for high-quality industrial development. Over 70 % of the exhibitors in this exhibition are leading “high-tech,” “specialized, refined, and innovative,” “invisible champions,” and “individual champions” enterprises. The overall solutions, as well as the new technologies and products showcased, reflect a significant increase in digitalization, low-carbon approaches, integration, and resource utilization.

Breakthrough of regional influence to gain more exposure

Since its entry into the western region of China in 2019, IE expo Chengdu has grown in scale and influence. Over the three days of the exhibition, it welcomed over 32,000 visitors from 32 provinces, cities, and autonomous regions.

The number of visitors from other cities in Sichuan has doubled compared to the previous edition, including Mianyang, Deyang, Leshan, Meishan, Ziyang, Suining, Nanchong, Yibin, and Luzhou. Furthermore, IE expo Chengdu's influence continues to expand throughout the western region of China, with a 75 % increase in trade visitors from Chongqing compared to the previous session.

The exhibition received coverage from 35 mass media outlets, including People's Daily Online, Xinhua Net, Sichuan News, Daily Economic News, and China Economic Times. Additionally, with the expanding influence of new media in the environmental protection industry, the exhibition topics garnered over 1 million exposures.

Thinking exchange leading the way to future innovations

With the goal of promoting industrial exchanges, IE expo Chengdu collaborated closely with industry associations and trade media to organize 15 high-quality industry conferences and forums. These events brought together over 130 industry experts and leaders, including Kebin HE, an academician of the Chinese Academy of Engineering and a professor at the School of Environment, Tsinghua University, and Bin LUO, the president of the Sichuan Institute of Environmental Policy Research and Planning. The topics covered urban green low-carbon initiatives, resource recycling, industrial wastewater reduction, and resource utilization. The supporting program attracted over 3,000 participants, providing them with useful case studies and intellectual support.
