The DSD recycling company's national recycling system is based on its contract with more than 500 private and waste management companies. It is a model that is not subject to geographical restrictions; at the same time, DSD is a privately owned organization that serves the public interest. Under the premise of national environmental policy requirements, in the form of fee-based operations, the interests of all parties in the local government, waste management departments, and recycling companies are coordinated, and the responsibilities and responsibilities of all parties are clearly defined so that the recovery can be carried out smoothly.
DSD company issued a "green dot" logo for the packaging companies and importers entrusting them with the recycling of packaging waste and charged them. Charges are calculated according to the weight, volume and area of ​​the different types of recycled waste packaging.
Calculated by weight: 150.8 cents per kilogram of plastic packaging; 107.3 cents per kilogram of composite packaging; 86.4 cents per kilogram of beverage cardboard box; 76.6 cents per kilogram of aluminum packaging; 28.6 cents per kilogram of tin can Charge 20.4 cents per kilogram of paper/cardboard packaging; 10.2 cents per kilogram of natural packaging material; and 7.6 cents per kilogram of glass packaging.
From January 2002, the above fees have dropped by 11%.
Calculated by volume: <50 to 200 ml, charge 0.05-0.31 cent;> 200 ml to 3L, charge 0.36-0.46 cent;> 3L, charge 0.61 cent.
Calculated on an area basis: <150 square centimeters to 300 square centimeters, charge 0.05-0.20 cents;> 300 square centimeters to 1600 square centimeters, charge 0.31 cents;> 1600 square centimeters, charge 0.46 cents.
After packing companies, importers, and trading companies have paid their bills, they can use the “Green Point†logo registered with DSD. By 2000, DSD had already owned 17,900 companies that used its “Green Dot†logo. 340 million tons of packaging waste was recycled, reused and disposed of.
The DSD company's recycling mark is only used on disposable packaging. Reusable packaging, such as beer bottles, does not use the "green dot" logo, but is paid for by the "deposit" method. For packaging wastes with the "Green Dot" logo printed on them, DSD companies recycle them through "send" and "take" systems. For large amounts of glass (separated by green, white, brown), paper and cardboard waste, and corner waste, the company uses the “send†system to send the vehicle to the recycling processing company for centralized recycling after using the garbage bag to centralize the packaging. For scattered packaging waste, the company sets up garbage collection bins (barrels) near residential areas and pedestrian walkways. The bins (barrels) are available in three models: large, medium, and small, and are selected according to need; garbage cans (barrels) are also Divided into different colors, the waste collection, blue bins (barrels) collection carton carton, yellow bins (barrels) to collect all kinds of waste light packaging, such as plastic, composite, tin cans, cans and other waste packaging, gray Or brown bins (barrels) to collect other debris.
In 2001, Green Point collected an average of 76.6 kg of recyclable waste from each inhabitant, including glass packaging 30.0 kg, light packaging 27.91 kg, and paper/cardboard packaging 18.7 kg.
DSD two-way system for the recycling of packaging waste recycling operation description: Its use of recycling circle: packaging product manufacturers → sell the packaging to the production company for packaging or filling, the production company to pay a green point fee to the two-way system → production companies Disposable packaging products can be printed with green dot logos → handed over to the store for sale → consumer purchases → post-consumer scrap packaging Recycling by the Green Point company using its investment in a garbage bin → recycling companies contracted by Green Point or contractors will be scrapped After the material is collected, it is transported to the recycling factory → the production of recycled raw materials (or made into other products) → return to the manufacturer of the packaging products to produce recycled products.

Separation and regeneration 1. Waste paper In Germany, 75% of waste paper is newspapers and magazines, and 25% are paper and cardboard. In 1999, 214.6kg/person/year was recovered, which has good economic value for recycling. After the “send†and “take†systems were recovered, they were used in the past. The automatic waste paper sorting line is now used for sorting. After the waste paper is shredded, it is separated by weight (specific gravity) so that it can be sent to the company. The quality of recycled pulp after paper mills. If waste newspapers and magazines are mixed with 5% paper/paperboard, it will seriously affect the quality of high-grade pulp. Therefore, Germany has high requirements on the quality of sorting, and it is stipulated that the mixed paper must not exceed 1.25%.
2. Waste composite packaging beverages Cardboard packaging mostly uses aluminum-plastic composite materials. Its composition is 80% paper-based, 16% PE plastic, and 4% aluminum foil. Germany recycles 130,000 tons of composite packaging every year.
The recovery and separation process is as follows:
(1) After tearing and crushing the waste composite package, the waste water can be separated and formed into fiber pulp by utilizing the characteristics of water absorption of the waste paper. After the fiber pulp is extruded into a large package, it is transported to paper mills in Finland and Germany for papermaking. Food packaging paperboard fiber is long, good quality, and therefore welcomed by the paper mill.
(2) After tearing and separating the paper, aluminum foil (aluminum oxide) and PE are not good enough to be separated, so most (75%) are sent to the cement plant as an additive for the production of cement; (25%) can also be pyrolyzed, and aluminum oxide remains after burning off the plastic PE (which can be used as a heat source). (To be continued)
