Plastic is an incredibly versatile material that is found in a huge variety of different types of products. It is also very easy to make, which is one of its biggest advantages over other types of durable goods. Plastic is made through a process called polyethylene production. The raw materials of plastic include oil, water and oil derivatives such as petrolatum, methylene chloride, polyacrylate and etc. These materials are combined with stabilizers such as potassium hydroxide, sodium hydroxide, calcium thioglycolate and etc.
One of the most common uses of plastics is the manufacture of plastic bottles and cups. Plastic bottles are widely used because they are clear, tamper proof, leak proof, biodegradable and safe. Although plastic is extremely convenient, it has come at a cost, with plastic bottles having a life expectancy of around 5 years. This means that over time, the amount of plastic waste that is dumped in landfill sites increases massively, requiring environmentally friendly alternatives to plastic packaging and trays.
There are two main methods for dealing with plastics waste. The first is to recycle the waste, by separating the plastics and reprocessing them. This waste is usually collected from the local area and recycled within a closed system, before being sent off for sorting seal nhua niem phong. This collection system is not however appropriate for all types of waste, as certain plastics are broken down too quickly within the recycling process. Another way in which the waste can be recycled is through ‘remanufacturing’, in which case, the waste is actually repaired or manufactured in a similar way to the original plastic, using the same properties and functions.
The recycling of plastics is a great idea but has some disadvantages. The first major disadvantage is that the process needs to ensure that the plastics are broken down sufficiently. As most plastics cannot be recycled without damaging the material they are made up of, this means that any recycled plastic will usually contain a large amount of unusable material. As well as this, plastic cannot generally be recycled very quickly, as the process needs careful sorting and distillation to ensure that the chemicals and substances in the plastics can be separated out without causing damage to the other materials. Furthermore, even recycling the plastics using this method does not eliminate the associated costs of manufacturing the recycled plastic, as the process requires raw materials such as virgin oil, copper wire and polycarbonate sheets.
Despite the disadvantages, recycling of plastics still occurs, as many countries are now beginning to collect plastic waste in a commercial capacity. One of the largest collections is in the United Kingdom, where large cities suffer from a serious problem with plastic waste disposal. However, recycling the plastics does have its own disadvantages, as producing the plastics requires large amounts of energy and water. Additionally, the high price tag that accompanies the production of new plastics means that the price of recycling the plastics will become higher over time. On top of this, the recycling process itself can sometimes damages the plastics, making them less viable for use in manufacturing future plastic products.
Because of these factors, it is clear that the majority of plastic products produced today are not easily recyclable. Some plastic types are so durable that they are difficult to break down for use in manufacturing. Plastic is one of the most durable materials, meaning that it is difficult to crack or break into the plastic itself. Most plastic is also highly resistant to acid rain, meaning that the only way in which most plastics can be damaged is by chemical reaction with other substances in the environment. As a result, non-recyclable plastics include packaging, food containers, polythene bags, plastic milk jugs and many more, meaning that although recycling of plastics may help the environment, it is not likely to have a major impact on the environment in general.
