Introduction In recent years, the fast-growing poplar species has been widely planted in northern China, and it has become an important raw material for pulping.
On the development of chinese paper industry, the planting of fast-growing hardwood is the most efficient way to solve the shortage of wood raw material.
EXPERIMENT Materials: Chips of Fast-growing Poplar were obtained from trees (5-year-old,height 10.8 m,diameter 18.7cm) grown in Hebei province.

According to the requirements of the two ministries, all the related local governments undertook to accelerate construction of recovery system to guarantee raw material supply.
As a major component of “urban minerals”, e-waste is an important raw material of “urban materials” demonstration base.
Practical Significance of Informationization of Beijing E-Waste Recycling Network Informationization of Beijing e-waste recycling network will promote the scientific management and high-efficient operation of the recycling network, and provide a solid guarantee for the supply of raw materials of “urban minerals” demonstration base in Beijing.
Promoted by “urban materials” demonstration base, China's e-waste recycling network will accelerate the upgrade and pay more attention to standardization and informationization on the basis of hardware construction, in order to improve the operating efficiency of recycling network.
