It is known to all and is used as packaging for a wide variety of products: water, juices, soft drinks.What made the plastic bottle?Such packaging plays a ubiquitous role in our lives of consumers.With our growing awareness of environmental issues which surround the plastic, many are interested in the life cycle of the material, from production to subsequent disposal in a landfill or recycling.The realization of this process can get consumers to think over how they use and dispose of waste.
Structure, basic properties
What made the plastic bottle?It all starts with the receipt of raw materials - oil, which comes from the distant fields.Upon receipt for the further processing of all cargo in containers, tankers and shipped to factories.What made the plastic bottle? from petroleum.By heating and mixing the hydrocarbon with a chemical catalyst, causing polymerization obtained plastic.In addition, in the processing of its allocated different components.Further refinery receives gas, fuel oil and other products.What makes plastic bottles?Most of them are made of polyethylene terephthalate (PET known as plastic).One important chemical parameters - viscosity, which is determined by the size of polymer molecules.What made plastic bottles, both from the material they create?Polietilentereflat widely used in Russia for the production of different types of pieces, so-called "preform".Next, after heating from them are made (blown) forms of all kinds, especially plastic bottles.
What made plastic bottle, more than it can be replaced?Do not we all know that some manufacturers care about the environment, using bioplastics from plant materials (Bioplastics).For this purpose their first processed to form polymers.This is followed by the conversion process, resulting in a new bioplastic material.It is believed that it is better for the environment because they do not require the extraction and processing of oil and non-renewable resources.However, such an exchange of plant material decomposes rapidly and is not stored for a long time.Besides, in case of long exposure of the bottle of a material can be deformed and flow.Also, it is believed that in the situation of bioplastics is also not without its environmental problems.Its production requires large areas of agricultural land to grow crops.In addition, they consume large amounts of water, fuel and other resources.
Fighting rubbish
worldwide constantly increasing production and consumption of plastic packaging.As a consequence, there is a storage of waste that is not biodegradable.This plastic bottle - a very common worldwide form of waste.However, discarded, they are not all fall into landfills.The world's oceans are filled with such waste, which poses a serious threat to many marine organisms.Instead of the complete destruction of the plastic actually breaks down into very small segments that can be consumed by the inhabitants of the oceans.The small town of Concord (Massachusetts) - the first town in the United States where a ban on the sale of water in plastic bottles.
