Circular economy of packaging industry at home and abroad (Part 1)

I. overview of circular economy

the so-called circular economy is an economy that integrates cleaner production and comprehensive utilization of waste. In essence, it is an ecological economy, which requires the use of ecological laws to guide the economic activities of human society. Therefore, circular economy is an economic development model that promotes the harmonious coexistence between man and nature

the law of the world economic development process shows that when the regional per capita GDP is at the stage of $500, it often corresponds to the period when the bottleneck constraints such as population, resources and environment are the most serious. These areas are densely populated, with rapid economic growth and relatively insufficient resources. The contradiction between ecological environment, natural resources and socio-economic development has become increasingly prominent. Only by realizing the coordination between economic development, resource development and utilization, and environmental protection, can sustainable development be achieved, which must take the road of circular economy based on the effective use of resources and environmental protection

compared with traditional economy, circular economy is very different. From the direction of material flow, the economy of traditional industrial society is a one-way flow linear economy, that is, "resources - production - consumption - waste discharge". The growth of linear economy depends on the large-scale exploitation and consumption of resources, while exceeding the limit to destroy the natural ecology and cause environmental pollution; Circular economy advocates an economic development model based on the continuous recycling of materials. It requires that economic activities be organized into a process of "resources production consumption renewable resources" and a process of repeated circular flow of materials according to the model of natural ecosystem, so that the whole economic system and the production and consumption process basically do not produce or only produce a small amount of waste

in short, circular economy is the use of natural resources and environmental capacity according to ecological laws. The theory of circular economy is a "win-win" theory between economic development and ecological environmental protection. It is a fundamental change to the traditional growth mode of "mass production, mass consumption and mass abandonment", and puts forward a new economic mode of integrated development of resources and ecological environment

circular economy requires "3R" as the code of conduct for social and economic activities. The "3R" principle aims to reduce the quality of materials entering the production and consumption process, among which "reduce" is to save resources and reduce the emission of pollutants; "Reuse" requires products and packaging containers to be used for many times to reduce environmental pollution of disposable products; "Recycle" requires that goods can become renewable resources after completing the use function

in practice, circular economy should be implemented at three levels. First, the material circulation within the enterprise. In the production process of enterprises, reduce the emission of pollutants until the goal of zero emission cycle protection is achieved. The second is the medium circulation at the regional level. Several interconnected enterprises are jointly built in one Park (i.e. the ecological comprehensive score of 91.8 (excellent) Industrial Park). According to the requirements of the development of the ecological industrial chain, the park combines a series of interrelated ecological industrial chains. Through waste exchange and recycling between enterprises and industries, dnipeg announced to invest 15million US dollars to build new factories and cleaner production, Reduce or eliminate waste discharge. The third is the big cycle at the social level, that is, the whole country and society formulate relevant laws and regulations according to the requirements of circular economy, so as to realize cleaner production, cleaner consumption, recycling of resources and environmental purification from the perspective of data mechanics. This includes the material cycle of the whole process of production and consumption

II. Introduction to foreign circular economy

with the reduction of earth resources and the intensification of environmental crisis, developed countries continue to explore new economic development models and vigorously develop circular economy. Since the concept of "circular economy" was put forward in the 1960s, it has developed for more than 40 years in western developed countries, and has developed to a quite mature stage in Germany, France, the United States and our close neighbors Japan and South Korea, and has produced huge economic and social benefits. Their policy measures and advanced experience are worth learning from

Germany is one of the countries with the highest level of circular economy development in Europe. The German government has adopted very powerful policies and measures to promote the development of circular economy. The circular economy and waste disposal law passed in 1996 created a favorable legal environment for the development of circular economy in Germany. The main purpose of the law is to promote the development of circular economy and ensure the maximum reuse of garbage. At first, this practice of Germany was laughed at by the people of other European countries, but now it is actively followed. German enterprises have taken the development of circular economy as a part of their own interests, and actively made outstanding achievements, because this will greatly improve the reputation of enterprises. Due to the close cooperation between the government, enterprises and citizens, circular economy has developed into an important industry in Germany. Official statistics show that the German waste recycling industry creates 41billion euros of value every year. In Germany, the average proportion of waste generated by all production industries is 50%, or even 80%. In Germany, the concept of "garbage disposal" refers to the reuse of garbage as much as possible, rather than simple landfilling and destruction

Sweden attaches great importance to the recycling of waste packaging. In 1994, the Swedish conference officially established the "producer system" of waste recycling. Swedish law stipulates that all enterprises that produce, import packaging and packaging products, as well as those that sell packaging products, have the obligation to recycle packaging. In the same year, Sweden established four national specialized packaging recycling companies, namely, Swedish paper and paperboard recycling company, plastic recycling company, corrugated paperboard recycling company and metal recycling company. Together with the Swedish glass recycling company established earlier, these five companies undertook the recycling and reuse of packaging materials in Sweden. Since the implementation of the "producer system", Sweden has achieved remarkable results in packaging recycling. When the "producer system" was just implemented in 1994, 250000 tons of packaging materials were recycled. According to the evaluation report of the Swedish National Environmental Protection Agency, the average recycling rate of various packaging materials in 2002 reached 65%, more than 660000 tons. This means that a large number of waste packaging materials that were originally incinerated and landfilled are now being reused. As a result, the environmental burden is reduced, which is mainly used to determine the energy consumption of various paperboards and single-layer and multi-layer corrugated paperboards. In addition, the implementation of the "producer system" has also promoted the birth of a number of new waste packaging recycling enterprises. At present, Sweden needs to import about 145000 tons of packaging waste every year to meet the production needs of these enterprises. (to be continued)
