Packaging gets new life from here

exquisite and solid packaging often becomes waste in an instant. In recent years, the substantial growth of packaging waste has become a problem that can not be ignored, so the implementation of circular economy in the packaging industry is more urgent. From July 7 to 8, the Symposium on green packaging of the Chinese Academy of Environmental Sciences, hosted by the green packaging branch of the Chinese Academy of Environmental Sciences, was held against this background. The symposium focused on the definition of green packaging and the current situation, principles and Countermeasures of implementing circular economy and developing green packaging at home and abroad. Among them, the typical cases of recycling and disposal of packaging waste at home and abroad introduced by relevant experts are of great significance for reference

Germany "green dot": Taking the lead in the recycling of packaging waste in the world

xuhaiyun, chief engineer of the Urban Construction Research Institute of the Ministry of construction, said that Germany had not formed a system of who was responsible for pollution before 1989. At that time, the output of garbage in Germany was increasing, and local residents strongly opposed the construction of more garbage treatment plants. After investigation and research, professionals found that packaging materials accounted for more than 50% of the total waste in volume and more than 30% in weight. People can reduce the amount of waste by recycling recyclable packaging materials. Therefore, in order to change this situation, Germany formally implemented the "packaging regulations act" on June 12, 1991. The packaging regulation stipulates that the trade and industry circles are obliged to recycle transportation packaging, conversion packaging and sales packaging. At the same time, this regulation also provides producers and sellers with the possibility of entrusting a third party to help fulfill this obligation. On the one hand, the implementation of the regulation promotes the classified collection, recycling and reduction of packaging waste. As the main treatment machine, the recycled plastic granulator will have a large customer base, and also open up an important source of funds for urban waste treatment. German Dual Track System Co., Ltd., or "green dot" - German Recycling System Co., Ltd. (DSD) came into being in 1990

this is a recycling system coexisting with the local government waste treatment system. It was founded by about 95 industrial and commercial enterprises from the packaging industry, consumer goods industry and commerce under the initiative of the federal Federation of German industries and the German Chamber of Commerce and industry. DSD company changed into a profit-making limited company from December 15, 2005

according to the provisions of the packaging regulations, DSD company is responsible for establishing a recycling system near users to recycle packaging waste, so that sellers and manufacturers can get rid of their respective obligations. Ms. zhuqiuyun, a former consultant of DSD, said that the German government had not invested in the establishment of this system. The funds required for the business activities of DSD company mainly come from the collection of green dot royalties by issuing a "green dot" trademark license to the enterprise. Each packaging user, packaging manufacturer and seller must purchase the "green dot" trademark for his packaging. He must pay the DSD company the corresponding sales volume and packaging license fees, so as to reasonably bear the costs of the collection, classification and plastic utilization of waste packaging, which will be included in the product price and ultimately borne by consumers. If some enterprises do not use the "green dot" trademark, they are not involved in the system. They must recycle and reuse by themselves, complete the specified limit and show proof; Andre kosonov, the general manager of some enterprises in his bag A. A. C. polymers, said that if he used the "green dot" trademark without paying for it, his behavior violated the trademark law and would be punished

according to the introduction, the charging standard of "green dot" trademark is calculated according to the material, weight and quantity of packaging, that is, the total amount of green dot usage fee is the sum of weight fee and quantity fee. The composition of the license fee takes into account the actual processing cost of each packaging material. In order to reduce the "green dot" license fees, that is, to reduce costs, industrial enterprises try to improve their packaging and packaging materials as much as possible, and strive to develop packaging that is as environmentally friendly as possible. As a result of continuous optimization of packaging and refilling, packaging waste is greatly reduced and resources are saved. It is reported that in 2004 alone, DSD's packaging fee income was about 2billion euros, and 5.2 million tons of various packaging waste were collected, utilized and treated

Brazil: it has a unique sustainable urban waste management model

zouzuye, President of Beijing Packaging Technology Association, made a special investigation on the development of circular industry - circular economy in Brazil's packaging industry last October. He was deeply impressed by the local unique sustainable urban waste management model

he said that in the past decade, Brazil has 7. Digital timers: 1-99 points 237 cities have implemented resource recycling. Locally, the recycling system of urban waste is divided into five levels: 4, 3, 2, 1a and 1: 4 is a large recycling (use) enterprise; 3. It is a large recycling company, which has the ability to control vehicle equipment and recycled resources; 2 is a private truck recycling household, which is sold to "4" through "3"; 1A is a large-scale recycling station, a cooperative form supported by the government and large enterprises, which is responsible for sorting, compressing and packaging, and selling to users; 1. There are 500000 recyclers in Brazil

in addition to recycling the waste that will produce moire stripes, Brazil also advocates "making the best use of everything" for the recycled waste, and advocates increasing the utilization rate and added value of products and selling them to enterprises and consumers. For example, pick out the recycled old books, conduct sanitary treatment, and establish a library; Recycled old toys that can be repaired will be sent to charity institutions or private kindergartens after repair; Establish a wood art studio with waste wood and send products to supermarkets for sale. There is also a training course in Brazil, which provides 4-month carpentry training for some recyclers. After obtaining the certificate, students can get a small amount of government loans to set up a private woodworking company to engage in the processing of waste wood

in addition to the perfect recycling system, the recycling technology of packaging waste has also been developed in Brazil. The most typical is the treatment of packaging waste mainly Tetra Pak. It is reported that although aluminum plastic paper composite packaging has the largest value content in packaging waste, the recycling technology is also the most difficult. The technology of thermal plasma separation and treatment of aluminum plastic paper composite packaging, which was jointly developed by TSL, was developed to solve this problem. This technology has been built and put into operation in Olympia, Sao Paulo, Brazil, in April last year

zouzuye said that the demonstration plant was built near the karbin paper mill, and the two sides are connected in the recycling process. Tetra Pak, as the representative of the waste, is first sent to the pulp machine of the karbin plant to separate the paper fiber (as the raw material for the production of kraft paper), and the remaining aluminum-plastic mixture is sent to the demonstration plant, which is continuously put into the thermal plasma treatment furnace. At a high temperature of 15000 ~ 50000 degrees, both aluminum and plastic are gasified, the aluminum component sinks, and melts into aluminum ingots (purity is 99%), and the high polymer materials are gasified and condensed into colloids, which can be used as chemical raw materials. At present, the capacity of the demonstration plant is 8000 tons per year

according to zouzuye, the construction of such a factory requires an investment of about $5-7 million, and it is estimated that the recoverable cost will be two and a half years. This technology has been transferred to Germany, Spain and other EU countries

Shanghai: "Three Penny project" turns waste into treasure

Shanghai has taken the lead in the country to make great progress in the treatment of environmental pollution caused by disposable expanded polystyrene tableware, realizing the harmless treatment of disposable expanded polystyrene tableware waste, and the recycling rate has reached more than 70%. The participants spoke highly of Shanghai's practice

in 2000, the Shanghai municipal government promulgated the "Interim Measures" in accordance with the internationally accepted principle of "Whoever pollutes is responsible", and the management department charged the manufacturers a pollution control fee of 3 cents per piece as the funds for recycling. One third of the three cents are used for recycling, transportation, disposal and management. At the same time, similar to the practice of German green dot company, products that pay recycling and disposal fees will be labeled with special labels

at present, the "3-cent project" has given value to disposable plastic lunch boxes, giving birth to a complete circular industrial chain of disposable plastic lunch boxes from production, recycling to disposal, and producing a series of economic effects. About 95% of the recycled lunch boxes in Shanghai are processed into plastic particles in Kunshan Baolv plastic resource recycling treatment Co., Ltd. These particles can be further made into various building materials, air conditioning filters, TV shells, raincoat buttons, soles and heels, office stationery, etc. Over the past five years, 3687 tons of recycled plastic particles have been made from disposable plastic lunch boxes recycled in Shanghai

according to Kunshan Baolv plastic resources recycling treatment Co., Ltd., through the exploration of recycling disposable expanded polystyrene tableware waste in recent years, the company has transitioned from relying on the subsidy of disposable expanded polystyrene tableware production units in the initial stage to producing good economic benefits, with a profit of more than 1 million yuan in 2004

according to the person in charge of Shanghai Waste Management Office, from May 1st, 2006, disposable foamed plastic trays will be included in the management scope. Two new manufacturers of disposable foamed plastic pallets have been added for the record, and the used foamed pallets enter the recycling and disposal system
