Stone powder gravel, processed into a new type of environmentally-friendly building materials that are favored by the market; abandoned "cuttings", or successfully "transformed" into artificial marble, or made into exquisite handicrafts sold well abroad... as the largest stone production and processing base in the country and even in Southeast Asia And the distribution center, Nanan through the introduction of support measures, increase technical innovation and other initiatives, the city's stone industry is setting off a second revolution, singing energy-saving emission reduction songs, embarked on a cycle of sustainable development.
"Combination Boxing" to Develop Circular Economy
In recent years, Nan'an has vigorously implemented a development strategy of economic growth and environmental protection, and is committed to building an ecological civilization. In order to solve the environmental protection problems brought about by the rapid development of the stone industry in the city, the city has been striving to crack the recipe, and has successively produced a series of “combination punches†for the development of stone recycling economy.
In order to speed up the research and development of stone powder and gravel comprehensive utilization technology, Nan'an City Finance allocates 1 million yuan each year to establish a special fund for comprehensive utilization of stone powder and gravel, which is used to support stone powder and gravel comprehensive utilization enterprises. It also promoted the “Science and Technology Marriage†and jointly established the Building Materials Technology Development Center with Tongji University to carry out in-depth technical research and successfully realize turning waste into treasure. The city also vigorously guides stone enterprises to gather in industrial concentration areas, and intensifies law enforcement inspections, and resolutely adopts measures to stop power and stop production for enterprises that fail to meet environmental protection requirements. At the same time, the city actively guides stone enterprises to scale and brand development, improve access standards, and increase the minimum total investment of new stone enterprises to 30 million yuan.
In order to promote the exchange of new technologies, the 8th "Shibo Fair" will set up an energy-saving and emission-reduction zone for the first time, exhibiting artificial marble, mosaic, stone powder bricks and other products made from corner scraps, stone powder and gravel, and showcase the stone industry. New results.
New building materials industry favors stone powder
In the process of Nanan Stone Industry's efforts to develop circular economy, the project of stone powder aerated concrete block and autoclaved brick products invested and constructed by Fujian Guoneng New Building Materials Co., Ltd. has attracted much attention. The first phase of the company's project investment is nearly 140 million yuan, and an annual production capacity of 200,000 cubic meters of stone powder aerated concrete blocks and an annual output of 100 million pieces of autoclaved brick production lines will be built. After the project is put into production, it can eliminate 300,000-500,000 tons of stone powder every year, becoming a model project of circular economy in Fujian and even the whole country. The responsible person of the company was pleased to tell us that the project is expected to be put into production on November 20 this year.
In addition, the Wright Stone Powder Utilization Project has been put into operation in August this year, and Tongsheng Building Materials Co., Ltd., which uses a stone powder slag to produce aerated concrete cuts, was also put into operation as early as April. At present, the production of two new environmentally friendly products, such as natural stone paint and light silicate concrete block made of Nanan stone powder, can digest more than 400,000 tons of stone powder annually.
"Strip" became "Chan"
As soon as the technology is updated, the waste becomes gold. Another major source of pollution in the stone industry is the “cuttingsâ€. In recent years, with the continuous increase in scientific and technological innovation in the Nan'an stone industry, many companies in the city have set their sights on these “cutting materials†and used them as raw materials to produce mosaic puzzles and waterjet puzzles, which are sold well at home and abroad.
Recently, we saw in Wanling Mosaic Technology Co., Ltd. that several women workers are using a small piece of “cutting material†to create a colorful “great feltâ€, which makes the visitors who come to visit amazed. The person in charge of the company said that the treatment of “cutting materials†was a headache for many stone companies. Now it is completely different. The mosaic puzzles and waterjet puzzles made of “cutting materials†are favored by merchants from all over the world. It can be sold for more than 1,000 yuan, and most of them are exported abroad, and the medium-grade stone plate per square meter is only between three and four hundred yuan. At present, there are more than a dozen new stone manufacturers such as Wanling who are engaged in the processing of "cutting materials".
