We can always see people recycling plastic bottles, but do you know where these recycled plastic bottles go? In fact, most plastic products can be recycled, and through a series of means, the plastic can be reused and transformed into new plastic products or other uses. So what happens to these recycled plastics? In the end, in what form will plastic return to our lives? In this issue we talk about plastic recycling.
When a large amount of plastic is transported from all corners of society to the recycling plant, the first thing it needs to go through is to remove a series of substances that have nothing to do with the plastic, such as labels, lids, etc., then sort them according to type and color, and then sort them Break it into particles about the same size as pebbles. At this step, the preliminary processing of plastics is basically completed, and the next step is how to process these plastics.
The most common method is very simple, which is to melt plastic at high temperature and reshape it into other products. The advantages of this method are simplicity, speed, and low cost. The only trouble is that the plastic needs to be carefully classified and remade in this way. The performance of the plastic will drop a lot. However, this method is suitable for common plastics, such as our daily beverage bottles and other plastic bottles, which are basically recycled and reused in this way.
So is there any recycling method that will not affect performance? Of course there is, that is, plastics are broken down into their original chemical units, such as monomers, hydrocarbons, etc., and then synthesized into new plastics or other chemicals. This method is very crude and can handle mixed or contaminated plastics, expand the application scope of plastics, and increase the added value of plastics. For example, plastic fibers are produced in this way. However, chemical recycling requires high energy consumption and capital investment, which means it is expensive.
In fact, in addition to recycling and re-producing into plastics, there is also the direct incineration of plastics instead of fuel, and then using the heat generated by incineration for power generation or other applications. This recycling method has almost no cost, but the trouble is that it will produce harmful gases and pollute the environment. This recycling method will not be considered unless it is absolutely necessary. Only plastics that cannot be mechanically or chemically recycled or have no market demand will be used in this way. deal with.
What is even more special is a special plastic with degradability. This plastic does not require special treatment after recycling. It can be directly degraded by microorganisms and will not cause pollution to the environment. At Jiangsu Yuesheng Technology Co., Ltd., we have used many years of experience in equipment research and development to take the lead in developing degradable PLA foaming products. We provide customers with one-stop services based on their different needs and do not need to make changes to their existing equipment. If you make any changes, you can adapt directly!
There are also some more unique solutions that try to use recycled plastic to create other chemicals. For example, carbon black, which is used to make rubber, ink, paint and other products, is converted into carbon black and other gases by thermally cracking plastic waste. After all, in essence, these products, like plastics, can obtain raw materials through petrochemical industry, so it is not difficult to understand their interoperability.
What’s even more amazing is that recycled plastic can also be used to make methanol. Plastic waste is converted into methanol and other gases through gasification and catalytic conversion. This method can reduce the consumption of natural gas and increase the production and efficiency of methanol. After obtaining methanol, we can use methanol to make formaldehyde, ethanol, propylene and other substances.
Of course, the specific recycling method used depends on the type of plastic, such as PET plastic, which is a transparent thermoplastic commonly used to make beverage bottles, food containers, etc. It can be mechanically recycled into PET products with other shapes and functions. This process can be used in the PET production line of Jiangsu Yuesheng Technology Co., Ltd., which is mainly engaged in the research and development of plastic extruders and related equipment. With the production of enterprises, we can provide overall solutions for polymer material extrusion processing. The extrusion granulation unit with independent intellectual property rights continues to make progress and bring customers the highest quality products and the best user experience.
Plastic recycling helps reduce dependence on crude oil, save resources, protect the environment and human health, and reduce greenhouse gas emissions and the harm of plastic pollution. The waste plastics we throw away in our daily lives, if not reused through recycling, will one day return to human society in other ways. Therefore, for us, the most important thing is to classify the garbage well and let it be recycled. Those who go go, those who should stay stay. So do you know what to recycle plastic products?
