Practically, there is the possibility of making multi-use plastic bottles that can be used again as glass bottles, but no factory has done anywhere in the world. “Plastic bottles today are widely used in everyday life of humans, but researchers believe that the use of these bottles is not beneficial to health and can not be reused,” said Sinapress. Plastic bottles are not designed for reuse on the world market and are not robust enough against wear and tear in collecting, cleaning, loading and reuse on a commercial scale. Recycling plastic and plastic bottles, on the other hand, requires basic preparations, such as sterilization of bottles, which are usually carried out by washing with very hot water and chemical solutions, which in the end should eliminate all bacteria in these bottles. Be Normally, it would not be possible to expect a multiple use of plastic bottles, as these bottles, unlike glass bottles, have less firmness and are highly vulnerable to heat and are more reactive to chemicals. As a result, factories can not use these bottles like glass bottles that revert to production cycles. For example, in industries such as beverages, milk and dairy, … glass bottles are washed and refilled after collection, but it is not possible to do this for plastic bottles. Nevertheless, it should be kept in mind that it is practically possible to make multi-use plastic bottles that can be used again as glass bottles, but no factory has done anywhere in the world. The structure of the plastic bottles Most of the plastics we use in our everyday life are thermoplastic, thermoplastic, thermosetting, and thermosetting. Thermoplastics are acrylic, nylon and polyethylene. This group of plastics is warmed, deformed and soft so that they can be shaped in any way that makes the group easily recyclable from plastics. Thermosetting plastics, such as Bakelite or polyurethane, are quite different from the previous one, these plastics are not modified after being made to the desired shape by the manufacturers, and can not be melted or recycled. Disadvantages of consuming food and drink in plastic containers According to studies by researchers, eating a liter of packaged water can bring tens of thousands of micro-plastics into the human body. These particles are on average 100 microns and are known as microplastics as micro-plastics. This has been the case, however, as earlier studies by scientists at the Babaa Atomic Research Center in India have shown that using drinking water packaged in plastic bottles is harmful to human health because the chemicals present in these waters are higher than standard standards. Scientists recommend that stopping these plastic bottles be used for water. These studies have proved the destructive effect of chemical changes resulting from the consumption of water in plastic bottles in humans. In the above research, researchers investigated and tested water-based and packaged water bottles in plastic bottles of eighteen different manufacturers, and five samples of the water inside these bottles were also analyzed and tested. These tests showed a high level of harmful chemicals for human health inside these bottles and their drinking water. For example, according to the results of experiments, in a bottle of one liter of mineral water packaged in plastic containers, there are twenty percent bromate bromate, which is harmful to the human body. This chemical is known as one of the most important causes of diseases such as cancer, digestive tract infections and hair loss. Unfortunately, while over the past decade, the use of packaged drinking water bottles in plastic bottles has grown enormously, research has shown that a high percentage of bromate chemical is present in all mineral water products produced and manufactured by different companies. It has no connection with the water source, but it is toxic to the water through the water contact with the plastic body of the bottle, and especially in the vicinity of sunlight. It should be noted that in the official reports of the World Health Organization, the authorized level of bromate in drinking water is only 10%, and it is explicitly emphasized that the maximum amount predicted and approved by this substance should be four milligrams per liter of water in bottles Unfortunately, the amount of the aforementioned material is now much higher than this.
