The significance of waste paper recycling in the green packaging field Scientists call the various types of waste paper, waste wood fibers, and wood waste that have been discarded "fourth forest." Among them, waste paper refers to the general name of used paper and paperboard, and corners and corners of materials used in related industries such as paper and cardboard, or “secondary fiberâ€. The recycling of waste paper conforms to the development trend of the world's green packaging, has a direct relationship with environmental governance and resource protection, and has good economic and social benefits. The green wave centered on the protection of the environment and sustainable development aims to protect the environment and resources, make full use of renewable resources, and create a sustainable environment for humankind. Green packaging materials are the inevitable result of human beings entering a highly civilized world and the rapid development of the world economy. They have emerged from the call for human beings to maintain their living environment. They have the basic properties of general packaging materials (such as protection, processing operability, Appearance decorative, economical, easy to recycle, etc.), also has no harm to human health and eco-environment, is easy to recycle, and has unique properties that can be degraded by the environment and return to nature. In accordance with the requirements of environmental protection and the use of materials, the ownership can be roughly divided into three categories: recyclable materials (including paper products, glass, metals, linear polymers, degradable materials), materials that can be naturally weathered and returned to nature. (Including paper products, biodegradable, edible materials) and materials that can be incinerated to recover energy without polluting the atmosphere (including non-recyclable linear polymers, bulk polymers, and partially composite materials). Paper product is a kind of renewable green packaging material that is natural and can return to nature. The recycling of waste paper conforms to the development direction of “paper-based wood†and “paper-based plastic†in the packaging industry, and is in line with green packaging. Claim. Paper products that belong to green packaging materials occupy an important position in the entire packaging industry. They are widely used and have many varieties. Modern packaging from traditional packaging to today is always one of the pillar materials for packaging, accounting for the total output value of the entire packaging industry. 45%. For each ton of waste paper recovered by a paper mill, 800 kg of paper can be recycled, which is equivalent to saving 3 cubic meters of wood, saving 1.2 tons of coal, saving 100 cubic meters of water, saving 300 kilograms of chemical raw materials, and saving 600 degrees of electricity. Practice has proved that after repeated use of waste paper, the strength of the pulp remains basically constant. Although waste paper recycling will increase some costs and difficulties due to cleaning of debris and ink, it can reduce energy consumption and reduce the amount of papermaking accessories such as aluminum sulfate, caustic soda and other environmental pollution, and at the same time it can save raw materials and energy, and reduce packaging. The multi-effects of natural fiber raw material resource consumption, substitution of straw pulp to improve the quality of paper products, reduction of production costs and reduction of packaging pollution, protection of the environment, and maintenance of ecological balance.
