Green packaging, eternal pursuit (in)

After Germany used the “Environmental Mark”, many countries have also begun to implement environmental labels for product packaging. Such as Canada's "Maple Leaf Sign", Japan's "Love the Earth", the United States' "Natural Friendly" and Certificate System, China's "Environmental Sign", the European Community's "European Flower", Denmark, Finland, Sweden, Norway, etc. White Swans of the Nordic countries, Singapore's "green logo", New Zealand's "environmental choice", and Portugal's "ecological products".
In June 1993, the International Organization for Standardization established the “Technical Committee on Environmental Management” (TC207), which established a set of environmental management standards like quality management. To date, the TC207 committee has established some standards (eg ISO14000) and issued them for implementation. In the United States, the corporate and packaging industries have implemented the ISO14000 standard and developed related "environmental report cards" to evaluate the life cycle of packaging and improve the environmental management system of packaging companies. Japan established an environmental audit certification organization in October 1994. The European Community put forward the "European Environmental Management and Environmental Audit" in March 1993 and began implementation in April 1995. Some enterprises in China have also begun to implement the ISO14000 series of standards, but there is still a certain gap compared with foreign countries.
2.2 Green Packaging Regulations In 1981, the Danish government first introduced the "Container Packaging Recycling Act" in view of the adverse impact of the increase in empty containers for beverage containers. As the implementation of this law affected the free movement of goods within the European Community, the interests of member countries were affected. So a "Danish bottle" lawsuit hit the European court. In 1988, the European Court ruled that Denmark won. In order to alleviate disputes, the European Community held a conference in Dublin in June 1990 to put forward the idea of ​​"enhanced environmental protection." The Waste Transport Act was enacted, which stipulated that packaging waste could not be shipped to other countries. Countries should take responsibility for waste.
In December 1994, the European Community issued the "Packaging and Packaging Waste Directive." After the "Dublin Declaration," countries in Western Europe have successively formulated relevant laws and regulations. Responding to Europe, the United States, Canada, Japan, Singapore, South Korea, Hong Kong, the Philippines, Brazil and other countries and regions have also formulated the packaging laws and regulations.
Since 1979, China has promulgated four special laws and eight resource laws, including the "Environmental Protection Law of the People's Republic of China," "Prevention and Treatment of Solid Waste," "Water Pollution Control Law," and "Air Pollution Prevention and Control Law." More than 30 environmental protection regulations expressly regulate the management of packaging waste. In 1984, the country set up an environment and began implementing the environmental labeling system. In 1998, the provincial Green Packaging Association was established.
3 Main methods of green packaging 3.1 Starting from the use of materials 3.1.1 Biodegradable plastics At present, the internationally popular "degradable new plastics" have the excellent quality of self-decomposing after being discarded, and do not pollute the environment.
Germany invented a packaging cup made from starch and encountered insoluble liquid, which can hold dairy products. This invention saves 4 billion plastic bottles for Germany, and it is easily disassembled after being discarded. The United States has developed a plastic bag made from starch and synthetic fiber, which can be broken down into water and carbon dioxide in nature. Countries such as the Netherlands and Italy have already stipulated that certain plastic packaging materials must use biodegradable plastics, and no environmentally harmful packaging should be placed on the market.
3.1.2 Because paper can be reused after being used for packaging, a small amount of waste can be naturally decomposed in the natural environment, and it has no adverse impact on the natural environment. Therefore, the world recognized paper, paperboard and paper products are green products that are in line with environmental protection. The request can play a positive role in replacing the white pollution caused by plastics. At present, paper packaging materials being researched and developed at home and abroad include: paper packaging films, disposable paper product containers, paper packaging materials developed using natural resources, and edible paper products.
3.1.3 If glass does not contain other substances such as metal, ceramics, etc., the glass can be almost completely recycled. The content of other colored glass fragments in a certain color glass has the maximum limit: 1 The maximum content of other color glass in green glass does not exceed 15%. 2 The maximum content of other colored glass in white glass does not exceed 3%, in which the maximum content of brown glass does not exceed 2%, and the maximum content of green glass does not exceed 1%. 3 The maximum content of other colored glass in brown glass does not exceed 8%. For this reason, it is necessary to strengthen the separate collection of different colored glass. In some developed countries, white glass and stained glass are separately collected in different containers. Because glass packaging has strong visibility and is easy to recycle and reuse, it has become the main container for traditional packaging of beverages and other products.
3.1.4 bamboo bamboo packaging has non-toxic, non-polluting, easy to recycle and so on. Bamboo packaging refers to: bamboo plastic box, silk bundle box and so on. China is a country lacking timber in the world. However, China's total bamboo area and bamboo resources rank first and second in the world respectively. China's bamboo packaging with rich traditional culture has been favored by countries in Europe, America and Japan. (To be continued)
