Good at Changing Waste Material into Things of Value, Praised by CCTV to Do a Great Job in “Recycled Concrete”
2019-02
Trash is misplaced treasure. What else can we do with the waste of concrete, construction waste, etc.? After years of scientific research, STEC Shanghai City Building Material Co., Ltd successfully built an internal circular industrial chain. The measure of changing waste material into things of value also got the attention of CCTV, which was broadcast as a special program on the day of the closing ceremony of the 19th National Congress of the Communist Party of China.
On October 25, 2017, CCTV financial channel, in the special program, “New Beginning and New journey”, focusing on the 19th National Congress of the Communist Party of China, took “recycling building solid waste and generating recycled concrete” as the theme, and made special coverage on the new economic case of STEC Shanghai City Building Material Co., Ltd. on changing construction waste into things of value and creating recycling solid waste.
From lab to market
The amount of waste concrete produced worldwide each year is huge and rising year by year. In developed countries such as Europe and America, the recycling rate of construction solid waste is as high as 90%, but it is less than 5% in China. In 2005, STEC Shanghai City Building Material Co., Ltd. challenged the field, conducted strategic cooperation with Collage of Civil Engineering of Tongji University and Shanghai Research Institute of Building Sciences Group, and built the first national demonstration production line on Jungong Road. Regenerated concrete, a new green and environmentally friendly product, is well known as the construction of the World Expo pavilion - “Shanghai eco-house”. All the concrete used in the project structure can be recycled. After monitoring, the performance indexes met or exceeded the design requirements.
Misplaced treasure
The application of recycled aggregate can not only achieve the goal of resource recycling, but also reduce the dust pollution in the mining and transportation of natural raw materials, playing a good role of demonstration and guidance for the comprehensive utilization of efficient resource recycling of construction waste nationwide.
Effective solid waste utilization
After 12 years of technical study, the application of recycled concrete of STEC Shanghai City Building Material Co., Ltd. changed from pavement casting in preliminary stage to low-level architectural structure and to nowadays high-level architectural structure. In the field of comprehensive utilization of solid waste resources, we have continuously increased scientific investment and product research and development, especially the projects of key technologies and applications of high-performance regenerative concrete structure, the original achievements of which have reached the international advanced level.
It is learned that when scientific research was just been transformed into finished products, STEC Shanghai City Building Material Co., Ltd.’s annual output of recycled concrete produces reached only a few thousand cubic meters. In 2011, the company started to industrialize, and the annual output has been nearly 2 million square meters. Meanwhile, by internal coordination of STEC Shanghai City Building Material Co., Ltd., the successful application in the project has saved a lot of energy resources, such as Hongyuan Shengshi International Cultural City, SIPG 14 Districts, World Road, etc.
