This is because the plastic industry came up with a clever strategy in the early 1980s to put the recycling logo on the most commonly used plastic products. Therefore, most consumers believe that a large amount of plastic they consume is recyclable and will Through the roadside recycling program on the ground, it is reliably recycled. In fact, only a small part of the contents in the recycling bin will be recycled. To solve our plastic problem, the solution is not to recycle more, but to consume less.
If you are buying products containing plastic packaging, it is important to know which packaging materials are most likely to be recycled, so that you can make a shopping decision that understands the situation and is conducive to recycling. It is also helpful to understand the complex, expensive and energy-consuming recycling process (hopefully it can be used as an incentive to minimize plastic consumption) What happened after you threw the disposable plastic water bottle into your recycling bin? It can be seen from this process that paper and cardboard, steel, aluminum, and glass are the most likely items to be recycled.
Even a small piece of aluminum foil is worth throwing into the recycling bin because it will be picked up through a mechanical process that uses electric current and charge. Through the sorting process, paper, metal, and glass are not only more likely to be picked up and recycled, but these materials can also be made into new recycled products, almost like the original materials, and the recycling of these materials may continue to recycle At the end.
On the other hand, plastics can only be downgraded and recycled to make products with poor quality or few functions. For example, food packaging can no longer be remade into food packaging, it will return in the form of a product that cannot be in contact with food. These plastic resins move through the plastic manufacturing process and recycling cycle, turning into unrecyclable items at a relatively rapid rate, and finally thrown into the landfill, becoming plastic fossils that can exist for hundreds of years.
The specific steps of the recycling process:
Step 1 -throw the recyclable items into the sorting station to collect them into a pile, and then transfer the recovered items to the conveyor belt through the loader.
Step 2 -workers will then remove the garbage, oversized products, and plastic bags because they will block the operation of the system.
Step 3 -use the turntable to separate the cardboard from the recycling pile, the smaller items will pass and continue to go down.
Step 4 -the pile of items will be sent to another conveyor belt, and the workers will remove the remaining garbage or other pieces of cardboard.
Step 5 -Use a sieve to separate the paper (planar items), and the rest will continue to pass.
Step 6 -Remove the steel products with huge magnets and divide them into containers.
Step 7 -The glass jars will be crushed into pieces of glass and fall down, and the aluminum cans or foils will pass through the current classifier (power supply type) and transport them to another container.
Step 8 -the remaining piles of recycled items- is composed of plastic and garbage fragments. They will scan out the composition of each item through the outside line of the paper, and classify the target plastic fragments according to their resin type. Such as PETE, PET, HDPE, PVC, LDPE, PP, PS, etc.
Simply put, only No. 1 plastic (PETE or PET), No. 2 plastic (HDPE), and No. 5 plastic (PP) are suitable materials for recycling. It is important to consider the most likely materials to be recycled when shopping. Unfortunately, the plastic packaging of grocery products is increasing, not decreasing. Product packaging materials are gradually changed from those that are easily recyclable (such as glass jars) to non-recyclable materials (such as plastic-lined Tetra Pak bags).
Germany has been at the forefront of creative packaging waste management for more than 30 years.
In 1993, the German government passed a packaging decree requiring manufacturers to take back the packaging of their products. This decree covers glass, aluminum, and plastic beverage containers. These containers have a refundable deposit, which can be as high as 25 euros (equivalent to 29 US dollars) for plastic bottles in a "single direction". This is a very generous incentive. After the implementation of this plan, the recovery rate of PET bottles (plastic No. 1) in 2011 was 98‧5%.
After that, the city of Freiburg (Germany) proposed an innovative plan to deal with the waste produced by non-recyclable disposable coffee cups. Take-away cups are generally not recyclable, because the paper of the cup body is fused with polyethylene to make it waterproof. The resulting material cannot be easily sorted in recycling equipment. In Freiburg, coffee retail stores like bakeries, coffee shops, and restaurants buy reusable cups and use these cups to supply coffee to their customers instead of using disposable cups.
Customers will pay a deposit of €1 for the cup first, and they will get the deposit back when they return the cup to the store participating in the project. So you can take a cup of coffee in a java hut and dress it with reusable mugs, stroll to the other side of the town, and return the cup at another store. These stores will wash these cups and reuse them indefinitely. This is a good example of how the community can solve serious waste problems with a simple effort.
