The main ways of paper packaging recycling economy development

The packaging industry is a resource-consuming industry and the life cycle of packaging products is short. The growth of China's packaging industry is still an extensive mode of economic growth. The utilization rate of resources is low, and the energy consumption per unit of production is twice the world average, which is 11.5 times that of Japan and 4.3 times that of the United States.

Circular economy is a kind of economic growth model that takes the efficient use of resources and recycling as the core, and has the basic features of low consumption, low emission and high efficiency, and is consistent with the concept of sustainable development. The circular economy of the packaging industry will begin with four major links: reduction of packaging materials, recycling of packaging resources, efficient recycling of packaging waste, and energy conservation and emission reduction of packaging.

The National Development and Reform Commission has identified the concept of circular economy as the guiding ideology for China's "Eleventh Five-Year Plan". The circular economy has become an inevitable trend for various economic developments in China, including the packaging industry. In the future, with the development of industry, in the period of new important strategic opportunities, China will develop green packaging, recycling and recycling of packaging waste, save resources, achieve lightweight packaging, protect the environment, and reduce energy consumption, as a comprehensive packaging industry. The first driving force for development.

Reduce the use of promotional materials

The trend of international packaging development is to reduce the main trend, vigorously promote low-weight, high-intensity, lightweight, promote the use of micro-corrugated, special-shaped boxes, five-story box to three-tier box, to save resources, reduce production costs, protection The main purpose of the environment.

1. On the packaging paper, adopt low weight, high strength, and light weight, so as to achieve the purpose of reduction. Such as kraft linerboard, the international advanced countries generally use 100 grams to 140 grams of weight, while the domestic currently commonly used 150 grams to 180 grams of weight, the minimum in 120 grams, the highest 330 grams; corrugated paper international advanced countries commonly used 90 grams ~ 120 Grams, the current domestic use of 120 grams to 150 grams.

High strength base paper. The internationally advanced countries generally use all-wood pulp cattle cards and corrugated papers, which are of good quality. However, at present, there are some high-strength cattle cards and corrugated medium papers in China, which are quite different from imported papers. Domestic wood pulp has a low composition and a large amount of waste paper. Therefore, the price is low and the quality is poor. It is difficult to meet international standards, and it has some impact on the promotion of low weight, and can only gradually reduce the weight.

Lightweight. With the implementation of low-strength and high-strength, the weight of the carton box is reduced, and BF and BE tile types are used to reduce the amount of paper used, saving the country's timber resources and reducing the production cost.

2. The implementation of fine corrugated, special-shaped box. International advanced countries generally use BC corrugated cardboard boxes, heavy-duty cardboard boxes use AB or AC corrugated, micro-boxes and special-shaped cartons commonly used BF or BE corrugated, special-shaped boxes are characterized by convenience for consumers to carry, more popular in the international community. The domestic production of special-shaped boxes is not much, involving complex design, higher processing quality and equipment and other issues.

3. The implementation of a five-layer cardboard box was changed to a three-layer paper box. According to reports from international advanced countries, the ratio of three-layer boxes accounted for 85%, and the proportion of five-layer boxes accounted for only 15%. On the contrary, the proportion of five-layer boxes accounted for About 70% to 80%, while the proportion of three-tier box only accounts for 20% to 30%. If the three-tier box can reach the level of 85%, it can save a lot of timber resources for the country, reduce the cost of cartons, and reduce packaging costs for users and consumers. Therefore, we must vigorously publicize users' work and change the old concept of “the weight of the carton is good”; according to the weight demand, adopt good quality, low weight, high strength base paper, and reasonable calculation and design to help users change to three layers of boxes. The three parties benefit together.

Promote green packaging, comprehensive recycling of packaging waste

Green packaging should be a package that is harmless to the ecological environment and human health, can be recycled, recycled, and used to promote the sustainable development of the national economy. That is, the whole process of packaging products from raw material selection, product manufacturing, use, disposal and recycling should meet the requirements of ecological and environmental protection. It includes the contents of eco-environmental protection requirements such as saving resources, energy, reducing quantity, avoiding the generation of waste, easy recycling, recycling, incineration or degradation. In addition, the content of green packaging will have new connotations with the advancement of science and technology and the development of packaging.

Green packaging generally includes the following five aspects:

The first is to reduce packaging. The packaging should be used in the minimum amount under the conditions of protecting the goods, facilitating sales, and other functions.

Second, the packaging should be easy to reuse or easy to recycle and regenerate. The purpose of recycling should be achieved through the production of recycled products, incineration of heat energy, and composting to improve the soil.

Thirdly, packaging waste can be degraded and corrupted, and eventually it will not form permanent waste, thus achieving the purpose of improving the soil.

Fourth, packaging materials should not be harmful to humans and organisms. The packaging materials should not contain toxic elements, and viruses, heavy metals or these contents should be controlled within relevant standards.

Fifth, packaging products from raw materials collection, processing, manufacturing products, use, waste recycling and regeneration, until the final processing of the entire process should not cause pollution to the human body and the environment.

Promote the development of packaging recycling economy

The author believes that packaging companies should do the following:

1. Expand paper packaging products

Paper for wood, paper for plastic, paper for metal, paper for glass, etc., can protect the environment for the country, solve pollution and reduce waste that cannot be handled.

2. Comprehensive recycling of paper packaging waste

The life cycle of paper packaging products is short. After the general contents are used, the packaging box is discarded or sold as waste paper. The packaging company wastes and scraps are recycled as waste paper to the paper mill as raw materials to achieve recycling-use-to-manufacture recycled paper. Recycling; As people's living standards and consumption levels increase, some residents do not care about the recovery of waste paper, resulting in a low recovery rate. In 2007, the output of paper and board was 73.5 million tons, and the consumption was 72.9 million tons, while the waste paper recovery amount was 27.65 million tons. Waste paper recycling rate was only 37.9%. A large amount of waste paper was lost. The main loss was household waste paper. Therefore, the relevant government departments and waste recycling stations must pay attention to and strengthen the waste paper recycling work. Paper packaging companies attach great importance to the recovery rate of waste paper, basically reaching 90% to 95%, which can reduce production costs for enterprises. If the social waste paper recovery rate can reach 70%, it can provide more raw materials for papermaking. It is calculated by using 1.3 tons of waste paper to make 1 ton of base paper, with a recovery rate of 37.9%, reaching 27.74 million tons of recycled paper and 21.4 million tons of recycled paper. If the recovery rate is increased to 70%, 32% will be recycled, waste paper recycling will be increased by 23.52 million tons, and recycled paper will be 17.7 million tons, which is in full compliance with the concept of sustainable economic growth and recycling of packaging resources.

3. Promote packaging enterprises to save energy and reduce emissions

As China's economy has grown substantially and energy has not kept pace with economic development, the State Council has vigorously grasped the task of energy-saving emission reduction and production. At present, the country regards energy conservation and emission reduction as the key point of industrial development, and it has issued assessment indicators for energy conservation and emission reduction in various provinces, cities and districts.

How Packaging Enterprises Implement the Goal of Energy Saving and Emission Reduction in the Central Government

First, in the aspect of energy saving, it is necessary to seize the boiler steam recovery device so that a large amount of steam can not be leaked and can be recycled, thereby saving coal, water and electricity energy. After more than 20 carton enterprises in Shanghai have installed steam recovery devices, one boiler can save 300,000 yuan per year, install a steam recovery device of about 80,000 yuan, and can recover all installation costs in three months.

Second, the country’s energy resources are very tense, and it has a certain impact on the entire economy. Electricity, coal, water, etc. are planned to be allocated, especially during the summer. Some companies do not open night shifts on a day shift, avoid peaks in electricity usage, and require blackouts during peak hours. Some companies require production to stop production to ensure that key enterprises and residents use electricity, and electricity is lost after 10 pm, and electricity consumption is encouraged at night. Save electricity by 50% and reduce production costs. Educate the staff to keep the lights off, turn off the air, shut down, turn off the air conditioning habits, and promote energy-saving lamps in workshops and offices.

The third is emission reduction. Packaging companies mainly deal with printing ink cleaning wastewater and corn starch cleaning wastewater treatment. Although they are non-toxic and harmless, printing ink red, yellow, blue, black and other colors inflow into sewage pipes or rivers affect the environment and must be treated with sewage. Governance, and installation of sewage treatment equipment to solve and protect the environment.

The fourth is to reduce paper consumption, indirect energy-saving emission reduction. The production cost of packaging enterprises is mainly packaged paper, which accounts for 70% to 75% of the total production cost. It is extremely important to save paper consumption and reduce the loss in the production process. At present, a good carton manufacturer loses about 5% to 7% in the production process. A poor company has a loss of 1% or more, which means a 1% reduction in profits. It also wastes energy. The focus of carton enterprises is to reduce the use of packaging paper. Attrition rate.

In addition, the comprehensive utilization of waste paperboard will be strengthened, and waste paperboard will be used to make matching products such as lining plates, clips, gaskets, matboards, etc. to increase profits.
