How to find the balance of green packaging from circular economy (2)

(B) Development of Green Packaging Materials

1. Develop natural green packaging materials. Natural green packaging refers to packaging materials that use renewable natural resources to carry out pollution-free, less energy-consuming processing, and wastes can be efficiently recovered or rapidly decomposed without causing pollution to the environment. These raw materials have the characteristics of low environmental load, abundant resources, and cheap access. Making full use of bamboo, sawdust, hemp, cotton fabrics, wicker, reeds, crop straw, rice straw, wheat straw, and other raw materials, expanding the variety of packaging, and increasing the technical content are important directions for the ecological packaging.

  2. Research on ecological packaging materials and ecological transformation of traditional packaging. Ecological packaging materials are synthetic materials. We must examine the performance of design materials from the perspective of protecting the environment and protecting resources so that they meet the requirements of green packaging. The development of degradable plastics is currently a hot spot in the scientific and technological community in various countries. Its main target is biodegradation and optically degradable plastics. According to different manufacturing methods, biodegradable plastics can be divided into three types:

(1) microbial synthesis, also known as bacterial plastic. There are many microorganisms that produce polyester in nature. It is a very efficient method to produce degradable plastics by fermenting these microorganisms to polyester under proper conditions.

(2) chemical synthesis type. Most chemically synthesized macromolecule compounds are not degraded by microorganisms, but there are substances that are easily degraded by microorganisms among aliphatic polyesters and water-soluble macromolecules. Chemical synthesis of these biodegradable high-dose constituents can be made. Biodegradable plastic.

(3) Natural material utilization type. Chemically denatures natural polymer materials such as fiber systems and starches, making their properties such as strength, water resistance, and thermal plasticity similar to those of ordinary plastics. This plastic has low cost and good degradation performance.

(III) Clean production of green packaging materials

Cleaner production is the core of circular economy. The so-called clean production refers to the goal of energy saving, consumption reduction, pollution reduction, and efficiency improvement. It uses technical management as a means to design and produce optimal production processes and products to eliminate and reduce the adverse effects of industrial production on human health and the ecological environment. influences. The fundamental purpose of cleaner production is to carry out non-waste, less waste production, to achieve "zero emissions" of pollution in the production process and the greenization of manufactured products, that is, not only to achieve pollution-free and less pollution in the production process, but also to use and ultimately produce its products. There will be no damage to the environment during the scrapping process. Throughout the entire life cycle of green packaging, we follow the principle of “reduction, reuse, and recycling” of economic activities in the circular economy to minimize the impact of packaging on the environment.

The establishment of a company's environmental protection management system (EMS) is the key to the implementation of cleaner production, and is also the primary condition for the development of green packaging. To establish an EMS system, we must first assess the company's environmental behavior and environmental impact. The contents include the energy consumption and material consumption of packaging products, the emission indicators in the packaging materials production process and after the use of packaging products, and the activities of the company's enterprises are environmentally friendly. Comprehensive impact and so on. The evaluation results will help companies choose environmental technologies, clean processes and new management systems. On the basis of environmental assessment, we will establish an “environmental protection management system” whose core content is environmental policy, environmental planning, implementation and operation, inspection and correction, and management review. The EMS system will ensure that companies implement "green standards" and eventually achieve the goal of "green packaging." The environmental policy, environmental protection objectives and activity plan formulated by the company should be compatible with the company's own attributes, scale, production activities, products and services, and have the effect of saving resources, reducing pollution, recycling, and complying with relevant laws and regulations. Promise of. EMS will also be responsible for routine tasks such as environmental supervision and environmental inspections.

Second, expand the effective demand of the green economy and promote the development of green packaging

Green demand is the locomotive driving the development of green packaging. In the operation of the circular economy, we can start with investment and consumption and expand green demand.

(I) Encouraging green industries and expanding investment demand for green packaging

As a newly-packed industry, the green packaging industry has just begun to flourish in China. Most products have not yet reached scale production. They cannot meet the green consumer demand of the majority of consumers in terms of quantity and quality, and they have not yet formed a brand effect. At present, relevant government departments should seize the opportunity of economic structural adjustment, actively promote the merger and reorganization of enterprises, promote the rational allocation of resources, achieve the scale production of green packaging, increase the development of green packaging from the structure and total amount, and strive to meet the increasing market Green consumer demand. The government must strengthen incentives for packaging and manufacturing enterprises that implement the operation of the circular economy, and give policy sloping in terms of project approval, market access, taxation, and credit. Such as the reduction of taxes on green packaging products; the establishment of special funds to increase financial input to enterprises; increase the scale of corporate credit, give discount interest subsidies; on the import and export of raw materials and finished products, give preferential tariffs and quotas; support companies in Listing on the stock market creates conditions for absorbing social investment.
