Waste packaging materials to achieve a virtuous cycle

first, the recycling of waste packaging materials and recycling goals

at present, European countries, especially Germany, have a better recycling of all kinds of packaging materials, with a recycling rate of 83% and 79% in the Netherlands. At present, the recycling rate of waste packaging in China is less than 10%

the main problem affecting the recovery rate is the transportation and processing costs. The European Parliament has proposed that the recovery rate of metal packaging materials in Europe should reach 50% by 2006, requiring the packaging industry, users and consumers to work together to reduce the total amount of waste. After the total amount of waste recovery reaches the target, the environmental cost will be saved by 350million euros. The overall goal is that the total recovery of various packaging materials will be 25% - 45% in 2001 and 55% - 70% in 2006, of which the metal recovery rate will be increased from 15% to 50%

in addition, governments of various countries have also taken corresponding measures to adapt to the wave of green consumption. For example, in order to promote renewable utilization and the use of recycled packaging products, the EU stipulates that non reusable or non renewable packaging products will be excluded from the market from 2000

II. Advantages and disadvantages of packaging material recycling

pay attention to the recycling and reuse of packaging waste, and save energy and resources. According to relevant data analysis, recycling aluminum materials such as cans can save 95% of the energy used in aluminum production; Recycling steel and glass waste can save 50% of the energy required for the production of this material

in recent years, the plastic products used for packaging in China have caused environmental pollution and harmed soil and crops because of their non-destructive properties. Burning, polluting the air; Buried, not rotten for 200 years. If the waste plastics discarded every day in Beijing are recycled and refined, 500000 liters of unleaded gasoline and 500000 liters of diesel oil can be obtained. Gasoline alone can drive about 30000 cars for 100 kilometers. Plastic products can be recycled and reprocessed to make new plastic products, so that resources can be recycled. China has more than 15 million tons of packaging waste every year, one third of which is waste plastic; The annual demand for plastic in China is about 11million tons, with an annual output of only more than 6 million tons of plastic. The gap of 5 million tons needs to be imported. 120 tons of waste cans can recover 1 ton of tin, which is equivalent to mining and smelting 400 tons of ore, and does not include operating expenses

aluminum plastic composite packaging is widely used in food factories, pharmaceutical factories and other product packaging. With the progress of society, waste is increasing year by year. Due to the combination of aluminum and plastic, it cannot be granulated, no one cares about recycling, and can only be incinerated, which not only pollutes the environment but also wastes resources. Using aluminum-plastic automatic separation agent, put the waste aluminum-plastic packaging into the container, add water and automatic separation agent, the aluminum-plastic packaging will completely separate the aluminum-plastic in about 20 minutes, and 0.85 tons of recycled plastic and 0.1 tons of waste aluminum can be separated from each ton of aluminum-plastic packaging, Every (see ASTM C 363) day, 1 ton of waste aluminum-plastic composites is recycled, with a profit of yuan

metal containers are light, easy to transport and store. From the perspective of environmental protection, they are renewable materials, which can be completely degraded in. The disadvantage is that the tank is easy to be damaged, easy to rust and lack of visibility

due to the characteristics of glass, the packaging of glass containers can provide hygiene assurance after being equipped with metal screw caps. Glass containers are usually used for food packaging containers with high value and specific needs of consumers. Its disadvantage is that there is the possibility of breakage on the canning line and during transportation, which affects the cost. The packaging of glass containers has very strict requirements on the quality of wide mouth bottles. It is essential to adopt safety shockproof devices and collision avoidance devices, which can better show the high efficiency of the production line and the excellence of products

third, promote the recycling of packaging materials

many developed countries have taken positive measures in environmental protection packaging, such as legislating that beer, soft drinks and mineral water must use recyclable containers; Enact laws that enforce the recycling or utilization of packaging

Germany promulgated the waste act 30 years ago, and later formulated the circular economy and waste avoidance act, taking the lead in legislation towards a circular economic society. As a newly industrialized country, Japan has doubled its taste of the bitter fruit of environmental destruction and pollution. In the 1990s, Japan put forward the slogan of "building a country with environment", and formulated a number of regulations on waste treatment, renewable resources utilization, packaging containers and household appliances recycling, chemical substance management and so on. Japan's "container packaging recycling law" implemented in April 1997 stipulates that the manufacturers are responsible for recycling PET bottles and glass bottles. The weight of these containers accounts for 20% to 30% of the total weight of household equipment waste. However, due to their large volume, they account for 60% of the total. This method 7. the journal adopts the specific method of the paper. Please use the law in Annex 1 to apportion the cost of waste treatment among companies, consumers and municipalities. Previously, this cost was borne by the tax revenue of the government. When consumers abandon a container, they need to classify it in advance and send it to the designated place in the city. Manufacturers go to these places to recycle these containers. Since April, 2000, the recycling of paper and plastic packaging materials should also be handled in accordance with this law

EU requires all members to formulate laws and regulations on recycling packaging waste, and the recovery rate is required to reach 50%-65%. Since June 30 this year, EU countries have imposed new restrictions on commodity packaging, and any packaging must not contain 1 in 10000 heavy metals, otherwise it must not be sold. Subsequently, in view of the high lead content of recycled glass containers, the European Union announced that glass containers could be exempted from the restrictions on the content of heavy metals in several cases, so as to encourage manufacturers to recycle glass. The key points of the relevant regulations are as follows: (1) if the content of heavy metals in glass bottles exceeds the specified standard, it is purely caused by the addition of recycled remanufactures, and the limit of heavy metal content can be exempted. (2) Lead, tin, mercury and hexamethylene chloride shall not be intentionally added to glass containers. For this reason, Spain has drafted a bill that will lift the restrictions on the content of heavy metals in glass containers. In order to cooperate with the implementation period of the EU's relevant provisions on packaging materials, the Spanish draft bill is valid until June 30, 2006. Unless the EU extends the relevant period, all glass containers must meet the heavy metal content standards originally listed in the EU directive after June 30, 2006

the United States enacted the resource conservation and recycling act in 1976, which plays a decisive role in solid waste management. Recently, it is proposed to amend the regulations on beverage bottles and cans and implement the industrial self payment to increase the recycling rate of bottles and cans. Pat Franklin, spokesman of CRI (container circulation mechanism), said: "In 1999, more than 114 billion containers were discarded in the United States, and the market strategies and packaging choices of beverage companies have accelerated the occurrence of waste problems. Therefore, CRI established a national beverage container recycling standard, which must achieve a recovery rate of 80%, and requires beverage companies to be directly responsible for meeting this requirement. Under the new law, all soda, beer and other beverage companies need to establish their own plans to achieve the recycling goal, which The plan will be submitted to the U.S. Environmental Protection Agency for approval. "

in 1998, China promulgated the interim management measures for the recycling of packaging resources, which stipulates the disposal of waste. Experts called for the establishment and improvement of the "resource recycling law" as soon as possible, which is of great significance to the realization of China's sustainable development strategy. At this stage, China urgently needs to establish and improve the resource-based system, form a continuous cycle of "production consumption waste reproduction", and avoid taking the old road of developing the country again. "With the legislative guarantee of turning waste into treasure, 15million tons of waste packaging can't be casually 'thrown'
