In the process of China’s urbanization, where will a large number of construction waste go?According to the statistics of the Ministry of industry and information technology, China produced 1.5 billion tons of construction waste in 2012, of which only tens of millions of tons were used as resources, and the utilization rate was less than 5%. The recovery rate of construction waste in China is extremely low, and most of the construction waste will be transported to the relevant villages or suburbs without corresponding treatment.

 In this regard, industry experts said that in addition to harmless treatment of construction waste, it is also necessary to realize resource recycling, otherwise it is difficult to really solve the problem, and the green steel structure construction mode in line with “four sections and one environmental protection” has undoubtedly become a major direction for the development of the construction industry.

 Data show that in the total carbon emissions, the traditional construction industry accounts for almost 50% of the total carbon emissions, which is far higher than that of transportation and industry.In Europe, Australia and Japan, the local construction industry is very concerned about carbon constraint and circular economy. Prefabricated steel structure housing has developed to a very perfect stage, accounting for more than 40% of all residential buildings.This kind of fabricated steel structure can greatly save resources, protect the environment, reduce pollution, and provide healthy, applicable and efficient use space for people.

 The core of steel structure building is industrialization.Steel structure building has a high use of scientific and technological innovation and modern means, and can realize “turning waste into treasure”.The treated industrial waste can be used for steel structure to turn the originally landfill construction waste into building raw materials. For example, industrial waste can be used as the main material in the composite wall of the building, and the industrial waste such as fly ash can be used as the main material in the light grouting filling material.In fact, steel structure has made great progress because of its multiple advantages.

 Experts pointed out that with the country’s increasing emphasis on environmental protection, green and energy-saving buildings will become the focus of urban construction in the future. With the promotion of urbanization, it is estimated that a trillion yuan green steel structure construction market is forming rapidly.
