On November 8th, as one of the highlights of the 10th China Shuitou International Stone Fair, the first round of the stone industry circular economy exhibition area was set up to show the achievements of Nanan Stone Enterprise by increasing the intensity of technological transformation and turning waste into treasure. Products such as waste, stone powder, artificial marble made of stone enamel, mosaics, etc. are introduced to customers at home and abroad. At present, there are 135 stone crushing stone comprehensive utilization enterprises in Nan'an, with an annual output value of 1.5 billion yuan. The annual utilization of stone powder is more than 1.8 million tons, crushed stone is more than 1.5 million tons, and the comprehensive utilization rate of stone powder is 70%. It has exceeded 90% and has become the country's largest green recycling industry for stone recycling economy.
The data shows that the above-scale stone enterprises in Nan'an City realize zero discharge of sewage, and the energy consumption of the stone industry is 0.43 tons of standard coal per 10,000 yuan. There are 135 stone crushing stone comprehensive utilization enterprises, including 41 enterprises above designated size, and there are 5 provincial-level circular economy pilot parks and enterprises, which basically eliminate the environmental pollution generated by the stone industry.
In 2005, some members of the CPPCC National Committee of Nan'an submitted the proposal on “Supporting the development and utilization of stone powder and turning waste into treasureâ€, and promoted a special fund for the comprehensive utilization of stone powder and gravel for 1 million yuan per year. In the past four years, this move has played a "four-two-pound" effect, setting off a circular economy in the stone industry.
In order to accelerate the research and development of stone powder and gravel comprehensive utilization technology, Nan'an City and Tongji University jointly established the Building Materials Technology Development Center to carry out technical research. At the same time, actively guide stone enterprises to gather in industrial concentration areas, and increase law enforcement efforts, resolutely take measures to stop power and stop production for enterprises that fail to meet environmental protection requirements. Actively guide the development of stone enterprises in the direction of scale and branding, improve the threshold for entry, and increase the minimum investment amount of new stone enterprises to 30 million yuan.
In the stone industry circular economy exhibition area, the person in charge of Nan'an Pengxiang Gangshi Company told the reporter that the green artificial granite series products launched by the company this year are all processed from recycled stone waste, and while maintaining recycling, they have also maintained The product does not contain radiation and is processed green from raw material to product.
In Mingchao Stone Industry Co., the reporter saw that the company's production water is all used to recover groundwater. When the enterprise was put into production, the sewage recycling system was built in the same year, which can save more than 3,000 tons of water per year. Like Mingchao Stone Industry Co., many Nanan stone enterprises have consciously assumed the social responsibility of pollution control through technological innovation and technological transformation.
At present, Nan'an has emerged as a number of circular economy demonstration enterprises such as Guoneng Building Materials, Wright Building Materials, Xiejin Ceramics, Pengxiang Gangshi, Nanxing Marble, etc. The city has more than 100 enterprises that rely on “eat†stone powder and gravel. Driven by these companies, the scrap that was once regarded as a white pollutant has now become a sought-after "sweet".
