1. Sand and gravel are the most widely used basic construction materials, and for a long time, China has relied primarily on mining and river‑bed extraction to meet this demand. In recent years, the rapid expansion of infrastructure projects and real estate development—particularly the accelerated pace of urbanization—has led to a sharp surge in the demand for construction sand. Although Fujian boasts abundant natural sand and gravel resources, natural river sand is a non‑renewable resource that cannot be replenished in the short term. Prolonged overexploitation has left the entire province facing the looming prospect of depleting its natural river‑sand reserves. As the state strengthens ecological balance and intensifies environmental protection policies, numerous mines have been shut down, and the extraction of natural sand from lakes and inland rivers has been either banned or severely restricted. This has triggered an acute shortage of sand and gravel, with supply‑demand imbalances driving up the price of natural river sand. Driven by profit, washed sea sand, rock fines, and quarry sand have slipped through regulatory oversight, compromising material quality and creating hidden risks for construction projects. To safeguard finite river‑sand resources, prevent excessive and indiscriminate extraction that harms the ecosystem and jeopardizes the safety of river embankments, navigation, and bridges, replacing natural river sand with manufactured sand has become an inevitable trend in the industry.

2. As China’s society has entered a new era, and in response to the shift from high-speed economic growth to high-quality development, the company is actively pursuing a transformation from a purely trading‑oriented enterprise into an integrated entity encompassing science, industry, and trade. Guided by the five major development concepts of innovation, coordination, green development, openness, and shared benefits, the company is working to adjust and upgrade its industrial structure. Moreover, promoting the development of the manufactured sand industry represents a concrete step in implementing Xi Jinping’s thought on ecological civilization and is an essential measure for protecting river and marine environments as well as natural sand resources.
