China is a country with scarce timber resources. According to the results of the eighth (2009-2013) forest resource inventory, the per capita forest area is only 1/4 of the world's per capita level, and the per capita forest volume is only 1/7 of the world's per capita level. In my country's wood consumption structure, the construction and construction sector is a major consumables consumer. Annual wood consumption accounts for about 1/3 of the country's total consumption, reaching 150 million cubic meters. Most construction timbers are high-quality varieties, but due to factors such as construction technology and usage habits, the number of turnaround uses is very low, resulting in inefficient use and waste of resources. Plastic formwork is a new generation of green building materials that accompanies the development of my country's plastic industry. It has the characteristics of high turnover, 100% recycling and reuse, and easy quality shaping. It is very suitable for national environmental protection and circular economy policies. It is estimated that if 1/3 wood bamboo plywood formwork is replaced by plastic formwork in the construction field, the annual consumption of wood bamboo plywood formwork can be reduced by 100 million square meters, and 2.5 million cubic meters of high-quality wood can be substituted, which is equivalent to a reduction of 43,000 hectares of deforestation. Reducing carbon dioxide emissions by 7.6 million tons, the advantages of low-carbon environmental protection are obvious.
In 2013, as the "Green Building Action Plan" was officially launched, green building actions in various regions were in full swing, and many provinces and cities issued supporting policies for green building subsidies to vigorously promote the green process. Among the green building assessment conditions, green building materials are a key project. In the process of rapid development of building formwork towards diversification and lightweighting, plastic formwork is the emerging fourth-generation concrete formwork after wood formwork, bamboo plywood formwork and steel formwork, due to its "environmental protection, safety and recyclability" green The characteristics of building materials quickly gained the attention and favor of many construction and formwork rental companies. In countries with relatively developed plastic industries, such as Germany, North America, Japan, and South Korea, plastic building templates began large-scale production and application as early as a few decades ago, gradually replacing wood templates with serious waste of forest resources and steel templates with high energy consumption. . Therefore, to plastic
Yoyogi not only conforms to the development direction of the national green circular economy, but also meets the interests of construction enterprises.
