From December 8, 2020, to March 6, 2024, Zhang Hongliang served as the secretary of the board of directors of Zhongchuang Environmental Protection, and has been a director of the company since March 22, 2021, and chairman of the company since January 2022.

Formerly known as Sanwei Si established in 2001, Zhongchuang Environmental Protection became listed on the GEM in 2010, becoming the first environmental protection company in China to be listed with high-temperature dust removal filter materials as its main business. The company’s registered capital is 385 million yuan, with a workforce of over 1,200 employees. Over more than 20 years of development, it has transformed from a single filter material manufacturer to a comprehensive environmental service provider. Its main businesses include non-ferrous metal materials, filtration materials, and environmental governance, with main products including filtration materials, environmental engineering, non-ferrous metal materials (hazardous solid waste recycling products), and environmental sanitation services.
Financial reports of Zhongchuang Environmental Protection show continuous pressure on its revenue and net profit. In 2025, the company’s total annual operating income was 385 million yuan, a 17.44% decrease from 2024’s 466 million yuan; the net profit attributable to the parent company was a loss of 107 million yuan, marking the fifth consecutive year of annual losses, with an overall sales gross profit margin of only 8.23%. Intensified industry competition and reduced capital expenditures by downstream industrial enterprises have led to declines in revenue from filtration materials and environmental projects.
In the first quarter of this year, the company’s operating pressure has not eased, with quarterly revenue of 65.9673 million yuan, a 4.64% decrease year-on-year; the net profit attributable to the parent company once again recorded a loss of 13.3624 million yuan, down 16.33% year-on-year.
