The machines in the workshop roared, accompanied by the waving of the robotic arm, and photovoltaic modules were orderly transported out of the production line. At a new energy technology (Zhangzhou) Co., Ltd. located in Dongshan, Fujian, Sun Zhenghui, the quality assistant engineer of the "80s generation", focuses on the machine - unlike her father's generation of farmers, herdsmen, and fishermen, her generation of Dongshan youth has more job opportunities. Dongshan Island, located in the southern part of Fujian Province, is the second largest island in Fujian. Due to the scarcity of land and fertile land, for thousands of years, the people of Dongshan have relied on fishing for a living. However, in recent years, tower cranes have sprung up here, factories have sprung up, and millennium old agricultural counties have embarked on the path of industrialization. Many young people like Sun Zhenghui have chosen to return to their hometowns for employment. Previously, people used to say, 'Money is not brought by the strong wind,' but now our money is brought by the wind and sand! 'Sun Zhenghui joked,' The secret of 'East Mountain Rises Again' comes from a grain of sand. 'In the history of East Mountain, sand was once known as the' sand tiger '. In the past, sandstorms raged here, and more than ten villages were buried by yellow sand, causing displacement of the people. Until the 1950s, Gu Wenchang, then the secretary of the county party committee, led the people of Dongshan to plant casuarina everywhere, and finally built a "Green Great Wall", successfully blocking the invasion of quicksand. Now when we enter Dongshan Mountain, we can still see layers of Casuarina equisetifolia at the junction of water and sky. They are spreading dense needles, telling us the history of the struggle against Huangsha. The older generation may find it hard to imagine that one day, sand will not only be repelled but also turned into wealth. In 2007, Zhangzhou Qibin Glass Co., Ltd. settled in Dongshan, and the local sand caught the eye of the enterprise. Dongshan Sand is rich in resources, with over 200 million tons of silica sand reserves and a silicon content of over 97%, ranking among the top in the country as an excellent glass raw material. Pan Tianxi, the relevant person in charge of the Lingang Industrial Park Service Center in Dongshan Economic and Technological Development Zone, told reporters that as the first manufacturing enterprise to utilize local natural resources in Dongshan for industrial processing, Qibin Glass has also made many Dongshan people realize for the first time, Originally, sand can also be 'turned into treasure'. Backed by abundant silica sand resources, Qibin Glass has developed rapidly today, with an annual tax payment accounting for 14.22% of the local fiscal revenue in Dongshan. In recent years, the company has also implemented technological upgrades on 8 production lines and invested 4 billion yuan in the construction of photovoltaic glass projects. "Photovoltaic new energy is a new outlet. At present, we have invested in the construction of two photovoltaic Glass production production lines, and it is estimated that the annual output value of the project can reach 4 billion yuan after its full capacity." Shao Ruibin, Deputy General Manager of Dongshan Branch of Zhangzhou Qibin Photovoltaic New Energy Technology Co., Ltd., said that the added value of photovoltaic glass has increased by about 30% compared with traditional glass. While the industrial development is booming, Dongshan people have also noticed the hidden worry of the island development: natural silica sand is a non Renewable resource. How can we support the sustainable development of the industry only by resource mining and processing? In recent years, Dongshan has begun new explorations in the face of this topic. In October last year, the first high-efficiency single-crystal photovoltaic module in Fujian Province was officially launched after 31 processes in the assembly line. This is a new energy technology photovoltaic module project introduced by Dongshan County government. After the project is put into production, photovoltaic glass from Qibin can be directly assembled into photovoltaic
