In China's timber consumption structure, the construction industry is a major consumer, and the annual consumption of wood accounts for about one-third of the country's total consumption, reaching 150 million cubic meters. Most of the building timber is of high quality, but it is affected by construction techniques, usage habits and other factors, and the number of turnover uses is very low, resulting in inefficient use and waste of resources. The plastic formwork is a new generation of green building materials produced along with the development of China's plastics industry. It has the characteristics of high turnover, 100% recycling and easy to shape, and is very suitable for national environmental protection and recycling.


China is a country with scarce timber resources. According to the results of the eighth (2009-2013) forest resource inventory, China's per capita forest area is only one-fourth of the world's per capita level. China's per capita forest reserves are only 1/7 of the world's per capita level. . In China's timber consumption structure, the construction industry is a major consumer, and the annual consumption of wood accounts for about one-third of the country's total consumption, reaching 150 million cubic meters. Most of the building timber is of high quality, but it is affected by construction techniques, usage habits and other factors, and the number of turnover uses is very low, resulting in inefficient use and waste of resources. The plastic formwork is a new generation of green building materials produced along with the development of China's plastics industry. It has the characteristics of high turnover, 100% recycling and easy to shape, and is very suitable for national environmental protection and circular economy. According to estimates, if one-third of the wood-plywood plywood formwork in the construction field is replaced by a plastic formwork, the annual consumption of the wood-powder plywood formwork will be reduced by 100 million square meters, and the substitute high-quality wood will be 2.5 million cubic meters, equivalent to a reduction of 43,000 hectares of deforestation. Reduce carbon dioxide emissions by 7.6 million tons, and the advantages of low carbon and environmental protection are obvious.

In 2013, with the official launch of the “Green Building Action Plan”, green building actions in various regions were in full swing. Many provinces and municipalities have introduced supporting policies for green building subsidies and vigorously promoted the green process. Green building materials are a key item in green building assessment conditions. In the process of rapid development of building templates towards diversification and light weight, plastic formwork is the fourth generation of concrete formwork after wood formwork, bamboo plywood formwork and steel formwork, because it has “green, safe, recyclable” green The characteristics of building materials quickly gained the attention and favor of many construction and template leasing companies. In countries with relatively developed plastics industries such as Germany, North America, Japan, and Korea, plastic building formwork began to be used in large-scale production decades ago, gradually replacing wood formwork that wastes serious forest resources and steel formwork with high energy consumption.
