Primary And Secondary School Textbooks Recycling Technology

In the deteriorating environmental problems today, the perspective of the environmental protection and sustainable development has been accepted by most people, and environmental protection has become increasingly been highlighted. Circular economy has fund an economic mode with applied value for sustainable development. Circular economy is a kind of strategy of conservation of resources, whose principles are "reduction, reusing, recycling". What it seeks isn't to reduce the consumption of resources, but the resources to be made possibly use of efficiently and circularly, thereby achieving greater efficiency of resource and reducing the waste, and the circular usage of the textbook makes use of this principle.After students and teachers in Xi'an investigated about the circular usage of the textbook, they support the circular usage of the textbook, but they haven't yet identified the deeper understanding of the significance of the circular usage of the textbook, so it still needs to carry on extensive publicity. This thesis focus on calculation and analysis of economic performance after carrying out the circular usage of the s, and considerable economic performance is achieved by this way. This thesis also provides a detailed analysis that the circular usage of the textbook attains a purpose of conserving the resources and controlling the wastes by increasing times of circulating usage, resulting controlling pollution ahead, reducing pollution costs required and reducing ecological damage, as a result it is of great significance to push the development circular economy. When carrying out of the circular usage of the textbook, the experiences used should be made use of and the project of carrying out the circular usage of the textbook will be carried by various stages and regions step by step. In addition, the development of the teaching material should face electronic teaching material, which takes up smaller space and sharing resources by making good use of internet. Electronic teaching material achieves the complete scripless, which has more significant environmental significance.
