Waste paper recycling in packaging industry

The discarded waste paper, waste wood fibers and waste wood materials being seen as the fourth forest by the scientist. The waste paper refers to the used paper and carton packaging, as well as the use of paper and cardboard corners in related industries. Waste paper recycling conforms to the development trend of the world green packaging, environmental governance and resource protection, with good economic and social benefits. The green wave of environmental protection and sustainable development as the core, its purpose is to protect the environment and resources, make full use of renewable resources, and create a sustainable environment for human beings. Green packaging materials mankind enters a high degree of civilization, the world economy has entered a rapid development of the product came into being in the human requirements to keep the voices of the living environment, both the basic performance of general packaging materials (such as protection, processing operability decorative appearance, economical, easy recovery processing, etc.), and also has the unique characteristics of environmental degradation on human health and it is eco-friendly.

The carton packaging is a green packaging material which derived from natural and can return to natural, waste paper recycling in line with the packaging industry direction of replace plastic and wood, in line with the green packaging requirements. The paper products throughout the packaging industry occupies an important position, and it is widely used, more varieties, from traditional packaging to today's modern packaging has always been one of the pillars of material packaging, it accounting for 45% of the entire packaging industry output 45. Recycling one ton paper could produce 800kq new paper, equivalent to saving 3 cubic meter timber, 1.2t coal, 100L water, 300kg chemical raw materials, 600kw power. Practice has proved that the waste paper after repeated use, the strength of the pulp remains the same.

Although waste paper recycling increased costs and difficulties due to the clean-up of debris, ink, etc., but you can reduce energy consumption, reduce the amount of paper accessories such as aluminum sulphate, caustic soda which pollutes the environment, saving packaging to receive raw materials and energy, reduce consumption of natural fiber raw material resources, lower down the cost and reduce pollution.

Now the production of recycled paper mainly used for pulp raw materials, in order to make more effective use of waste paper, the developed countries tried to explore new ways to study waste paper utilization (such as the production of packaging and building materials, to improve agricultural and livestock production, methane production, manufacturing pencil rod, etc.), and has made great progress.
