But do you know what plastic is?<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\"> <\/span><\/p>\n<p><b>Meaning and origin<\/b><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">The word <\/span><b>plastic<\/b><span style=\"font-weight: 400;\"> comes from the Greek and means <\/span><b>something that can be<\/b> <b>molded<\/b><span style=\"font-weight: 400;\">, and this is one of the most important characteristics of the material.<\/span><\/p>\n<p>Its history begins during the late 19th and early 20th centuries, <span style=\"font-weight: 400;\">when the first synthetic plastic was developed and advanced at a rapid pace beginning in the 1920s. Today, plastic is present in nearly all spheres of our lives, for being a cheap, versatile, inert, lightweight, and resistant material, which elevates the quality of life of society in general.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"> <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Main Types of Plastic Composition<\/b><\/p>\n<p>&nbsp;<\/p>\n<p>Today, plastics are already being made from different raw materials, even from vegetable sources, such as green polyethylene or PLA, a type of biodegradable plastic made from sugar cane or corn syrup, but traditionally plastic is composed of resins derived from petroleum.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">In the refinery, petroleum is fractionated into by-products such as gasoline, kerosene, diesel, n<\/span>aphtha<span style=\"font-weight: 400;\"> and many others. And it is precisely naphtha that gives rise to the substances necessary for the production of the main types of plastic.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Moreover, plastic belongs to the group of polymers, large molecules with a variety of characteristics, hence its versatility.  These molecules are made up of other smaller molecules, called monomers, which through the process of <\/span><b>polymerization<\/b><span style=\"font-weight: 400;\"> are chemically united, generating the polymer.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">In general, plastics can be divided into two groups: thermoplastics and thermo-rigid.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"> <\/span><\/p>\n<p><b>Thermoplastics<\/b><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Plastic that soften when heated and become solid when cooled, which allows it to be molded and take new shapes, a process that can be repeated several times. Thermoplastics account for 80% of the plastics consumed. Among them are:<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PET, present in beverage bottles, packaging for cleaning products, textile fibers and more;<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">HDPE (high density polyethylene), widely used in the production of pharmaceutical product packaging, gas or liquid pipes, among other other applications;<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PVC, best known for composing pipes and connections for the civil construction sector, but which is also present in footwear and surgical equipment, for example;<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">LDPE (low density polyethylene), common in food packaging, industrial packaging, industrial bags, garbage bags, agricultural tarpaulins, flexible films for packaging and other purposes.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">            Among others.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"> <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Thermo-rigid or thermosetting<\/b><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">These are plastics that do not melt when heated, which makes it impossible to reuse them through conventional recycling processes.
