The story begins with the welding sparks that flickered in the Yixing Cold Working Machinery Factory in 1983. Group founder Zhang Juping was tempered through thousands of trials at the grassroots level, not only honing solid skills but also participating in the introduction of advanced foreign technology in 1987, achieving the localized application of key equipment. In 1990, with perseverance, he secured his first order worth 600,000 yuan, officially opening the door to the market. In 1993, with the spring breeze of private economic development, he founded Yixing Tongyong Environmental Protection Equipment Factory in a rented workshop, deeply embedding the gene of "surviving through quality" into the enterprise's bones.

The Group's growth has been a steady, step-by-step "Long March." From building its own factory in 1999 to relocating to the Yixing Economic Development Zone in 2006, Tongyong Environmental Protection entered the fast lane of standardized development. They deeply cultivated Shanghai's environmental infrastructure construction, leaving the mark of "high quality and beautiful appearance" in over 30 wastewater treatment plants and more than 500 pumping stations.

2012 was a turning point of destiny. Through capital integration, the Group entered the industrial system of a listed company, completing an astonishing leap from equipment supply to industrial chain collaboration. Starting in 2016, the Group launched its "second venture," transforming toward an integrated model of "investment—manufacturing—engineering—operation." By 2025, the Group had grown into a comprehensive service provider with annual revenue of 572 million yuan and overseas business scale of approximately 60 million yuan, achieving a leapfrog improvement in strength.

In the second half of industrial upgrading, Tongyong Environmental Protection deeply understands: only innovation can ensure evergreen vitality. The Group has not only invested heavily in research and development but also made significant efforts in digital transformation.

Facing the future, Tongyong Environmental Protection Group has set its sights on a broader global landscape. On the basis of consolidating the domestic market, the Group is actively implementing its "going global" strategy, promoting the coordinated export of technology and services, and striving to build a Chinese environmental protection brand with international influence.

From an ordinary frontline worker to the helmsman of a group with annual revenue in the hundreds of millions; from a simple rented workshop to marching toward the international market. The development journey of Tongyong Environmental Protection is a vivid microcosm of serving the country through industry, and also the most resounding answer to "high-quality development." On the journey of the new era, this green giant ship is cleaving through waves, steadily advancing toward a more sustainable future.

TongYong Environmental Protection Group always takes quality as the core of the Group's development, building a quality control system covering the entire process of R&D and design, production and manufacturing, engineering implementation, and after-sales service, continuously improving product stability and engineering delivery capabilities, adhering to standardized and refined management, strictly implementing quality control processes, and exercising full-process control over key procedures and core links to ensure controllable product quality and reliable results.
