Looking for a "green road" for packaging

large consumption of resources, destruction of the ecological environment, increase of urban garbage, damage to the interests of consumers, and vulgarization of social atmosphere - these major "crimes" make excessive packaging become the target of public criticism. How to correctly select and properly deal with packaging and packaging waste is concerned by the whole society. Therefore, the term "green packaging" is gradually familiar to Chinese people. However, what is the real meaning of "green packaging"? Is the packaging that is easy to dispose of waste "green packaging"? I have increased investment in infrastructure, irrigation engineering facilities and the construction of social security housing. The country's "green packaging" is confused about where the way out is. With these questions, I interviewed relevant experts

understand the life cycle of packaging products

"green packaging" is also known as ecological packaging, which refers to packaging that is harmless or does little harm to the ecological environment, is safe and hygienic to human health, and can be recycled or recycled. For example, municipal pipelines are very basic for people's livelihood construction, and can promote sustainable development

Ren Fazheng, professor and doctoral supervisor of the school of food science and nutrition engineering, China Agricultural University, told that developed countries stipulate that "green packaging" should have the characteristics of low consumption, reuse, recycling, obtaining new value, degradability and so on

Professor Wang Rusong, a researcher of the ecological environment research center of the Chinese Academy of Sciences, vice president of the international society for human ecology and vice president of the International Association of ecological cities, said: "what 'green packaging' is more important is a social economic natural complex ecosystem problem." He believes that the content of "green packaging" includes life cycle assessment, life cycle design and life cycle management of packaging products

Professor Wang introduced that the earliest life cycle assessment was initiated by Coca Cola company of the United States. In 1969, the company's evaluation research on beverage packaging bottles attempted to conduct the whole process tracking and quantitative analysis from the excavation of raw materials to the final waste disposal, so as to determine which packaging bottle has the least impact on the environment and the least pressure on resource use

many consumers think that all paper packaging is "green". In this regard, caimingchi, deputy director and Secretary General of the plastic packaging Committee of the China Packaging Technology Association, believes that "green packaging" should be a packaging that is environmentally friendly from the processing of materials and products, which is a kind of material based on fossil fuels to the whole process of waste disposal; We should not take it out of context and unilaterally believe that the packaging that is easy to dispose of waste is "green packaging", which is conducive to environmental protection

What are the green packaging materials

paper, glass, plastic and metal are the four pillars of modern packaging. The research and development of green packaging materials is the key to the final realization of "green packaging". Professor Ren Fazheng introduced several kinds of green packaging materials at present:

-- reusable and renewable packaging materials. In Sweden and other countries, polyester PET beverage bottles and PC milk bottles are reused for more than 20 times; Dutch and American companies recycle 100% of PET containers

-- edible packaging materials. Queensland potato chip container company, Australia, has developed an edible container for potato chips, which adds sour, spicy, salty flavor, smoked flavor, sauce flavor, chicken flavor and other different flavors, making the taste of the container no less than that of potato chips. In Japan, deacetylated chitosan extracted from shells is used to produce an edible package. The fast-food noodles and condiments packaged with it can be directly cooked in the pot

-- degradable material. After the end of its service life, degradable plastic packaging materials can be split, degraded and reduced in the natural environment, and finally re-enter the ecological environment in a non-toxic form

a bag of fruit made of potato starch and fiber can reduce the damage of a large number of fruit packaging waste to the environment

green packaging: there is no alternative

Che Xiangfu, Deputy Secretary General of China Packaging Technology Association, believes that there are four factors affecting the development of China's green packaging industry: first, the investment structure is out of balance. Waste packaging treatment projects rarely enter the planning management and investors "through BOT, boot, boot, blt, PPP and other ways". Second, the late industrial content of green packaging has not been included in the national plan. Third, the state did not specify preferential policies for investment and taxation of packaging environmental protection projects, which could not attract large-scale private investment. Fourth, the input of science and technology is insufficient, and the input of civil society and society cannot meet the demand

Professor Ren Fazheng believes that the urgent task in China is to develop new green packaging materials to replace the original polluting materials. In addition, the products of the food packaging industry account for about 70% of the packaging industry, and the waste is the most serious environmental pollution. Professor Ren believes that edible packaging is a good way to solve this problem, but the research in this area is still in its infancy in China, and great efforts should be made in variety development, performance improvement and cost reduction. China also urgently needs to effectively recycle and utilize packaging waste, and establish and improve the recycling system

it is reported that in Germany, the government will impose a mandatory deposit on anyone who buys mineral water, beer and soft drinks packaged with non renewable materials. Customers can return the deposit only after they return the empty package to the store they bought. In the interview, Secretary General Cai Mingchi made a deep impression: in the face of the contradiction between packaging and the ecological environment, people should realize that environmental protection is not a slogan, but an action. To protect the environment, we may lose some conveniences and even pay a high price. Choosing "green packaging" often means paying more money and attention, but human beings have no choice
