How plastic bottle recycle？
Do you know how to recycle the plastic bottle thrown away every time it is used up? The world consumes about hundreds of billions of plastic bottles every year, of which the recycling rate is poor, less than 50% of the recycled plastic bottles will be sent to the sorting plant, but the problem is that there are many types of plastics, and it is difficult to separation.
As a result, non-recyclable plastic waste is sent to power plants, and steel plants are used for energy combustion. The remaining recyclable bottles are divided into hdpe bottles, pet bottles and pp bottles. These are all reusable plastics.
Sorting is first required, passing through a conveyor belt and then passing through a large trommel screen. This machine sorts objects according to size, packaging and other miscellaneous items.
Inside the drum, the smaller pieces of metal fall through the hole in the middle, while the rest of the mixture is sent to the air separator. Most of the lighter debris will be blown away, leaving only the hard plastic.
Next, with an infrared scanner, it can quickly identify four types of plastic. The first is the pp plastic, which will be bounced to another place, then the pad, and finally the hdpe through this series of sorting, which can screen out the plastic that can be recycled.
The sorted plastic is compressed into bales and sent to plastic factories. Among them, hdpe plastic is used to make pipes or plastic bottles, pp plastic can be used to make flower pots or buckets, and pet can be used to make clothes or sofas, which can save oil consumption and reduce energy waste.
What is bottle to bottle recycling?
Most of the plastic is still made into plastic bottles, Hdpe plastic bottles will be put on a conveyor belt, washed and crushed to make a colorful mixture the size of a fingernail.
These materials are then melted in an extruder, filtered, purified again, and after cooling, the plastic is processed into pellets, and several other plastics are processed in much the same way. After the factory gets the high-quality plastic pellets, the machine can make plastic bottles of any shape by heating and extrusion, which means that the hdpe bottle is made of another hdpe bottle, and the recycling of renewable resources is completed.
MEPER co extrusion blow molding machine,using recycled materials to create multi-layer plastic bottles, thus reducing the production of plastic waste.
Why plastic bottle recycling?
Since the invention of plastic, the use of plastic products has become increasingly widespread, bringing great convenience to people's daily life. But at the same time, the problem of plastic pollution is becoming more and more serious, and it has become a hot environmental issue that countries around the world pay attention to. How to find a balance between the convenience of life and the protection of the environment has become a common issue facing the world, and it is also a problem that each of us needs to think deeply about.
People mainly reflect the "visual pollution" and "potential hazards" issues, and most people still lack awareness of the long-term and deep "potential hazards" of waste plastic packaging. Specifically, it can be said from the following aspects:
First, there is too much land occupation. Plastic garbage stays in nature for a long time, generally up to 200-400 years, and some up to 500 years.
Second, pollute the air. Plastic, confetti, and dust fly with the wind.
Third, pollute water bodies. The plastic bottles and lunch boxes floating on the river and sea surface, the plastic bags and bread paper hanging on the branches above the water surface, not only cause environmental pollution, but also harm the health of animals if they eat the white garbage by mistake. Undigested and starved to death.
Fourth, fire hazards. Almost all white garbage is combustible, and methane and other combustible gases will be produced during the natural stacking process. Fire accidents that are easily caused by open flames or spontaneous combustion continue to occur, often causing heavy losses.
Fifth, white garbage may become a nest of harmful organisms. They can provide food, habitat and breeding places for mice, birds and mosquitoes, and the residues are often the source of infectious diseases.
Sixth, after the waste plastic packaging enters the environment, because it is difficult to degrade, it will cause long-term and deep-level ecological and environmental problems. First of all, waste plastic packaging is mixed in the soil, which affects the absorption of nutrients and water by crops, which will lead to a reduction in crop production; waste plastic packaging mixed with domestic waste is difficult to deal with: landfill treatment will occupy land for a long time, and domestic waste mixed with plastic It is not suitable for composting, and the sorted waste plastics are difficult to recycle because they cannot guarantee the quality; if livestock eat plastic film, it will cause digestive tract diseases and even death of livestock.
We call on everyone to pay attention to the problem of plastic pollution.
What happens when you recycle a plastic bottle?
First of all, the biggest benefit is environmental protection. We all know that plastic is difficult to degrade in nature, especially hard plastic items such as plastic bottles. If it is not artificially disposed of, burned or reused, it may take several dozen in nature. It takes hundreds of years to degrade completely. Moreover, due to the wide range of uses of this type of plastic products in our lives, many products use this type of plastic packaging, and the flow in the world is extremely large, causing serious white pollution to the society. Recycling plastic bottles is a good way to alleviate pollution. After recycling, it can be handed over to a professional team for reuse, which can effectively deal with the problem of plastic pollution and can relieve a lot of pressure on nature.
In addition, recycling plastic bottles can also improve our awareness of environmental protection. In this process, we can discover the seriousness of plastic pollution to the current environment, stimulate human desire to protect the environment, and improve our environmental awareness.
