Developed countries in foreign countries attach great importance to the reuse of packaging materials, that is, re-resources, which not only solve the major problems of environmental pollution, but also save the resources of packaging materials, and can produce remarkable social and economic benefits.
United States
The United States has developed plastics and wood scrap to make composite materials. The method uses a special molecule (graft copolymerization molecule) that can effectively connect plastic and wood fiber, coats the waste wood material (fine wood bar) with the molecule, and then cuts the plastic yoghurt bottle into thin strips and wood. The bars are mixed and put into the machine for heating and squeezing treatment to obtain a firm brown new material with good elasticity and durability and can be used as packaging material.
The United States also uses waste paper to make packaging materials. U.S. E-Tech Products Co., Ltd. makes use of recycled waste paper to make packing material Ecube, which resembles a box shape. After filling, it can make vulnerable goods such as eggs not move inside the box to avoid cracking losses. Used in filling, it is more convenient and quicker than foam, can fill any shape of commodity, recyclable, biodegradable and safe and non-toxic.
Long View Fiber Company of the United States uses recycled kraft paper bags to produce a high-quality zippered retail package that can be printed in three to four colors. It is divided into cowhide, bleaching and other colors to compete with plastic bags. Biodegradation, environmental protection and safety. According to the United States Institute of Bottle Recycling and other institutions announced that the United States, aluminum, plastic polyester bottles, high-density polyethylene bottles, glass bottles and other beverage cans recycling 41%, the recovery part of the equivalent of saving 32 million barrels of crude oil. In the recycling process, it is most effective for the beverage wholesaler to pay the deposit to the government. In the state that implements this approach, the recycling rate of bottles and cans averages over 78%, which not only protects the environment, but also saves resources. This is of great benefit.
Germany
The German company Krone has developed a successful high quality PET bottle recycling system. The processing volume is 15,000 tons of PET beverage bottles. The processed PET raw material can be directly used to make other PET containers, the production cost is greatly reduced, and the environmental benefits are significant. The PET bottle recycling system utilizes a chemical coating removal technology to remove PET surface adherents using hot alkali as a chemical coating remover, allowing any type of PET bottle to be recycled. Recycling products can be directly mixed to make preforms, and due to the low content of acetaldehyde and yellow pigments, they can meet the purity and quality requirements, and are particularly suitable for the packaging of food and beverages. The cost is 20%-30% lower than the new material.
German plastic recycling companies use waste plastic packaging materials to make useful products and new materials. The company collects the packaging materials from the yellow trash cans and the yellow garbage bags. According to the grouping of the materials, the collected plastics are sent to the sorting equipment for separate processing. First, the old plastics are remelted and reconstructed to produce recycled pellets or pre-cooked parts that can produce pallets, anti-noise materials or fences. The second is to decompose the old plastic into chemical components and then obtain raw materials such as synthetic oil or methanol.
Japan
A Japanese company uses chemical methods to decompose recycled PET bottles into new PET bottles. At present, about 70% of used PET bottles have been recovered as fiber materials, and the remaining used PET bottles are collected and recycled by the local government agencies. The PET is chemically decomposed, and the foreign matter is first removed by multi-stage depolymerization, and the PET is decomposed into BHET through refining and other processes. Ethylene glycol, which is effectively recycled, is also used as a solvent for dissolving PET bottles.
A Japanese company successfully developed the conversion of waste plastics such as polyethylene (PE) and polypropylene (PP) into petrochemical raw materials. The PE and PP catalysts in waste plastics can be cracked into a mixture of benzene, toluene and xylene. Oil (BTX) and hydrogen. The production process is in an automatic screening device. First, the plastics such as PE and PP are melted at 230° C., and then they are cracked into gas, and then cracked in a catalytic cracking tank containing potassium silicate, and the generated gas is separated in the separator. After separation, the obtained BTX mixed oil can be reused as petrochemical raw materials such as plastic raw materials and pharmaceutical raw materials.
The Teijin company developed a recycling method to recover DMT (dimethyl terephthalate) and EG (ethylene glycol) from used PFT bottles. The method smashes and cleans the waste PET bottles, and then dissolves them in EG. The PET is depolymerized and filtered at a boiling point temperature of EG and a pressure of 0.1 MPa to remove the impurities and additives, and the BHET reacts with methanol. Methanol boiling temperature and 0.1Mpa pressure, transesterification to generate DMT and EG. DMI and EG were separated by distillation, and the purity of recovered EMT and EG was more than 99%. DMT can be converted to pure TPA (terephthalic acid) for the manufacture of bottles and PET resins, and EG can be reused.
Brazil
The Parana Polytechnic Institute in Brazil has successfully developed a new method for recovering reinforced packaging materials made from paper, plastic, and aluminum foil. After recovering the 3 components of the packaging material by special chemical solvents, ie, after immersing the reinforced packaging bag in the solvent for 2.5 minutes, the plastic, aluminum, and paper in the package are layered, separated, and the residue is removed by high pressure. Solvents are classified and recovered as three substances. The solvent has an effect on any type of paper, PVC and polyethylene plastics. This technology can recycle packaging materials such as milk and juice, salt, vacuum coffee and eggs.
The New PET company, a Brazilian plastics recycling company, has established a new PET bottle recycling plant that can recycle more than 90,000 PET bottles per month, and the annual production capacity will reach 48,000 tons. The recycled PET bottles are processed into chips and pellets for supply to plastic processing companies.
United Kingdom
Fully implement recycling of large-scale recycled beverage paper packaging. The Smithsonian Paper Packaging Production Company recently invested a total of 500,000 pounds in the construction of a new plant that specializes in remanufacturing and using paper packaging. Each year, it can recycle about 180 million tons of recycled paper packaging. In order to promote the recycling of packaging paper, not only has the public been fully aware of their environmental protection, but it has also conducted a large number of promotional campaigns to create a social environment that fully recycles paper packaging.
Sweden
Great importance was attached to green packaging, and the use of a storage and recycling system for plastic and metal beverage packaging containers was implemented at the end of last year. Where beverages are filled and commercialized in plastic or metal containers, it must be ensured that an approved container storage recovery system is used. It is forbidden to sell containers that are not included in the storage and recycling system. According to reports, Sweden's PET beverage bottles and PC bottles can be reused more than 20 times.
Norway
Invented Tomra special machine to recycle beverage bottles, cans. The aircraft is placed near the supermarket population. People put the waste beverage cans and bottles into the round holes above the machine, and they will print out the coupons of the value of the bottles and cans printed from the printing outlet of the machine. After entering the round hole, the waste beverage bottles and cans are immediately scanned by the laser device. The microprocessor compares the information with the information stored in the can and immediately recognizes the type of each can or plastic, or glass, or metal. Enter the respective container in the sorting device. The Tomra recycling system plays an important role in the recycling of beverage bottles and cans. The use of this system by countries such as Europe, the United States, and Japan is quite common.
Finland
The National Highway Research Center blends various plastic packaging wastes into the asphalt and paves the way. First, the packaging wastes such as plastic bags, bottles, and blanks are crushed. After heating, the solvent is added to the asphalt after processing, and the ratio accounts for 30% of the asphalt. The paved highway has strong elasticity and is less noisy when rubbed against the wheels.
Korea
South Korea - The company successfully made make-up paper from waste milk cartons. Milk cartons are made from raw materials such as general plastics or synthetic resins and kapok and fibers. According to reports, five rolls (70 meters long) of makeup paper can be made for every 30 waste milk cartons.
Canada
In recent years, Canada has made remarkable achievements in recycling waste paper packaging. Canada introduced new technology for the recycling of waste paper in the United States, which allowed one third of Canadian papermakers to use paper from recycled waste (also waste wood chips and sawdust) to increase the production of pulp and packaging materials containing recycled fiber in Canada by 3 times. Cartons and other paper products can be recycled and regenerated up to 9 times.
Canadian VEG company invented the use of waste glass bottles to make sand. Using the glass crusher of the invention, waste glass bottles, including bottle caps, labels, etc., are ground into a fine powder, and the glass sand produced has a greater hardness and a wider range of use than ordinary sand. After it is mixed with concrete and pellets, it is sprayed on the outside of the building through a sandblasting machine. It shines and is stronger than ordinary sand. Glass sand can also be made into water filters, the effect is better than normal sand or activated carbon.
Italy
