Yellow text in the above graphic shows sources of plastic that eventually end up in the ocean. We use plastic products to help make our lives cleaner, easier, safer and more enjoyable. [25] In 1933, polyethylene was discovered by Imperial Chemical Industries (ICI) researchers Reginald Gibson and Eric Fawcett. Thermoplastics and thermosetting polymers are the two types of plastic. [20] Parkesine won a bronze medal at the 1862 World's fair in London. A polymer is a large molecule made of smaller ones, called monomers. [41] For example, plasticizers like adipates and phthalates are often added to brittle plastics like polyvinyl chloride to make them pliable enough for use in food packaging, toys, and many other items. [92][93], When different types of plastics are melted together, they tend to phase-separate, like oil and water, and set in these layers. The Ocean Conservancy reported that China, Indonesia, Philippines, Thailand, and Vietnam dump more plastic in the sea than all other countries combined. iron (from iron ore) requires 20-25 MJ/Kg of energy, glass (from sand, etc.) This means that they keep warm things warm and cool things cool. Controlled high-temperature incineration, above 850°C for two seconds[citation needed], performed with selective additional heating, breaks down toxic dioxins and furans from burning plastic, and is widely used in municipal solid waste incineration. Plastic-eating microbes also have been found in landfills. Most plastic produced has not been reused, either being captured in landfills or persisting in the environment as plastic pollution. The word polymer means “of many parts,” and polymers are made of long chains of molecules. With such a major investment, it was no surprise that Du Pont spared little expense to promote nylon after its introduction, creating a public sensation, or "nylon mania". Eco-plastics come in several different flavors: recycled petroleum-based plastics, plant-derived (bio) plastics and miscellaneous. However, in 1839, Charles Goodyear invented vulcanized rubber; a form of natural rubber heated with sulfur (and a few other chemicals), forming cross-links between polymer chains (vulcanization), improving elasticity and durability. [35]. Learn about plastics and how they improve our lives. Phenol-formaldehyde, commonly known as bakelite, is degraded by the white rot fungus, This page was last edited on 11 January 2021, at 09:12. For example, plastics make possible bicycle helmets and child safety seats. The two most widely manufactured plastics, polypropylene and polyethylene, behave this way, which limits their utility for recycling. The same material can be utilised as a casting resin, in inks and coatings, and has many other uses. [91] The plastics industry has known since at least the 1970s, that recycling of most plastics is unlikely because of these limitations. Photo: An oxy-biodegradable fruit and vegetable bag produced by d 2 w® for the UK's Co-op chain of grocery stores. Let’s start from the where microplastics come from: these fragments are “crumbs” of larger polymers, so-called primary plastics.When plastic ends up in water, it dissolves into smaller fragments.This is caused by many factors, for example ultraviolet rays, wind, waves, microbes and elevated temperatures.. In its bulk form it is very wear resistant, particularly if oil-impregnated, and so is used to build gears, plain bearings, valve seats, seals and because of good heat-resistance, increasingly for under-the-hood applications in cars, and other mechanical parts. Biodegradable plastics are plastics degraded by microorganisms into water, carbon dioxide (or methane) and biomass under specified conditions. PlasticsEurope is committed to being a reliable partner on standardisation issues. The plastics you put in your recycling bin are brought here to the material recovery facility. Polymers often are made of carbon and hydrogen and sometimes oxygen, nitrogen, sulfur, chlorine, fluorine, phosphorous, or silicon. [54] Microplastics are not a specific kind of plastic, but rather any type of plastic fragment that is less than 5 mm in length according to the U.S. National Oceanic and Atmospheric Administration (NOAA) [55][56] and the European Chemicals Agency. Some are run by municipalities. Naturally occurring materials, such as wood, horn and rosin, are also composed of molecules of high molecular weight. Some are transparent, making optical devices possible. Plastics manufacturing is a major part of the chemical industry, and some of the world's largest chemical companies have been involved since the earliest days, such as the industry leaders BASF and Dow Chemical. Many of the controversies associated with plastics actually relate to the additives:[30] organotin compounds are particularly toxic.[31]. [89][90] Compared with the lucrative recycling of metal, and similar to the low value of glass recycling, plastic polymers recycling is often more challenging because of low density and low value. [94] Thus, even when plastics have a resin code, or are collected for recycling, only a small portion of that material is actually recycled. In some instances, rodent, pest, or insect attack can also be considered as forms of biodegradation or environmental degradation. A polymer is a substance made of many repeating units. Plastic is any synthetic or semisynthetic organic polymer. They're large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers. Will coronavirus be the death or salvation of Big Plastic ? To customize the properties of a plastic, different molecular groups "hang" from this backbone. The term plastics includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur. Find articles, infographics and quizzes to inspire meaningful discussions with your family, friends, neighbors and the world about the power of plastics. Everywhere you look, you will find plastics. Some compounds leaching from polystyrene food containers have been proposed to interfere with hormone functions and are suspected human carcinogens. The development of plastics has evolved from the use of natural plastic materials (e.g., chewing gum, shellac) to the use of chemically modified, natural materials (e.g., natural rubber, nitrocellulose, collagen, galalite) and finally to completely synthetic molecules (e.g., bakelite, epoxy, polyvinyl chloride). Due to purposefully misleading symbols on plastic packaging and numerous technical hurdles, less than 10% of plastic has ever been recycled. An error occurred during the subscription process. Modern synthetic plastics were invented around 100 years ago. In the prototype design, manufacturing, and injection molding industry we interact with plastics on a daily basis. In some cases, small amounts of those chemicals can remain trapped in the product unless suitable processing is employed. Nylons still remain important plastics, and not just for use in fabrics. The first plastic based on a synthetic polymer was made from phenol and formaldehyde, with the first viable and cheap synthesis methods invented in 1907, by Leo Hendrik Baekeland, a Belgian-born American living in New York state. The backbone is the part of the chain that is on the "main path", linking together a large number of repeat units. In principle, plastics can be developed with virtually any combination of properties to accommodate almost any application you can think of. Most plastics are strong, long-lasting, and lightweight. Where microplastics come from. Examples include: polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). In 2009, it was estimated that 10% of modern waste was plastic,[24] although estimates vary according to region. [31], Whereas the finished plastic may be non-toxic, the monomers used in the manufacture of the parent polymers may be toxic. Plastics are easy to mould into any shape, and they can take on any colour. After the war ended, DuPont went back to selling nylon to the public, engaging in another promotional campaign in 1946 that resulted in an even bigger craze, triggering the so-called nylon riots. What are Microplastics? [28], However, the COVID-19 pandemic has had a devastating effect on the fossil fuel and petrochemical industry. [65] The Marine Conservancy has predicted the decomposition rates of several plastic products. Owing to concerns over the effects of such leachates, the European Union has restricted the use of DEHP (di-2-ethylhexyl phthalate) and other phthalates in some applications, and the United States has limited the use of DEHP, DPB, BBP, DINP, DIDP, and DnOP in children's toys and child care articles with the Consumer Product Safety Improvement Act. Plastics are the most common form of marine debris. [49] Much of this material may persist for centuries or longer, given the demonstrated persistence of structurally similar natural materials such as amber. Plastics could be used to benefit the environment. There are differing estimates of how much plastic waste has been produced in the last century. Plastics, also called polymers, are produced by the conversion of natural products or by the synthesis from primary chemicals generally coming from oil, natural gas, or coal. In World War II, supply blockades of natural rubber from South East Asia caused a boom in development of synthetic rubber, notably styrene-butadiene rubber. The raw materials used to produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil. The most common type of plastic is polyethene, which is a thermoplastic. Additionally, plastics degrade slowly, often over hundreds if not thousands of years. After The Plastics’ break-up, according to Cady, “Gretchen found herself a new clique, and a new queen bee to serve” (Mean Girls). One of the things all of us can do to protect and improve our environment is: recycling. They're large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers. But it also helps recycling collectors determine what items they can accept — and which ones go in the trash. ", J. Harry Dubois Collection on the History of Plastics, ca. Most plastics are durable and degrade very slowly, as their chemical structure renders them resistant to many natural processes of degradation. In addition, plastics can be made in many colors. They have countless uses. [66], In 2018, a survey by the Global Oceanic Environmental Survey (GOES) Foundation found that the ecosystem in seas and oceans may collapse in the next 25 years, potentially causing failure of terrestrial ecosystem and "very possibly the end of life on Earth as we know it";[67] the main agents of this prediction were hypothesized to be plastic, ocean acidification, and ocean pollution. Early plastics were bio-derived materials such as egg and blood proteins, which are organic polymers. [2], Production of plastics from crude oil requires 62 to 108 MJ/Kg (taking into account the average efficiency of US utility stations of 35%). [24] Among the earliest examples in the wave of new polymers were polystyrene (PS), first produced by BASF in the 1930s,[2] and polyvinyl chloride (PVC), first created in 1872 but commercially produced in the late 1920s. However, all plastics are not made alike. [42] Research in Environmental Health Perspectives finds that BPA leached from the lining of tin cans, dental sealants and polycarbonate bottles can increase body weight of lab animals' offspring. However, not all plastics are equal, since some are worse than others for marine life. Estimates of the global production capacity for bio-derived materials is put at 327,000 tonnes/year. Plastic, polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. Plastikos, Henry George Liddell, Robert Scott, "Global Market Trends and Investments in Polyethylene and Polyproplyene", "Scientists could have finally created the 'holy grail' of plastic", "Historical Overview and Industrial Development", "Those White Plastic Chairs – The Monobloc and the Context-Free Object | … My heart's in Accra". Recycled traditional plastic is composed of varying percentages of "virgin" (nonrecycled), traditional plastic. Through a process called cracking, crude oil and natural gases are converted to hydrocarbon monomers like ethylene, propylene, styrene, vinyl chloride, ethylene glycol, and so on. Plastics are organic materials, just like wood or wool. Carothers and his team synthesized a number of different polyamides including polyamide 6.6 and 4.6, as well as polyesters.[110]. After World War I, improvements in chemical technology led to an explosion in new forms of plastics, with mass production beginning in the 1940s and 1950s (around World War II). Plastics are polymers. Trust your plastics recycling questions to Miller Recycling. The final result was unsuitable for the original purpose. Plastics typically have high molecular weight, meaning each molecule can have thousands of atoms bound together. While plastics can be made electrically conductive, with a conductivity of up to 80 kS/cm in stretch-oriented polyacetylene,[14] they are still no match for most metals like copper; which have a conductivity of several hundred kS/cm. Plastics are simply chains of like molecules linked together. What Are Single-Use Plastics? Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years. Plastics are the source of innovations that contribute to sustainability, safety, longer lives and better performance. These long chains of carbon molecules give plastic its characteristic strength and flexibility. Most plastics contain organic polymers. Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene).. Separating Myth from Fact. Thermosets, or thermosetting polymers, can melt and take shape only once: after they have solidified, they stay solid. As of 2019, due to limitations in their economic viability, these facilities have struggled to make a meaningful contribution to the plastic supply chain. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger, who has been called "the father of polymer chemistry" and Herman Mark, known as "the father of polymer physics".[5]. Other types of thermoplastics include nylon, PVC and PVA. Plastics are a wide range of synthetic or semi-synthetic materials, that usually use a polymers as a main ingredient. Bioplastic is a biodegradable material that come from renewable sources and can be used to reduce the problem of plastic waste that is suffocating the planet and polluting the environment. Plastics contribute to approximately 10% of discarded waste. As a result of these attractive properties, plastics are being used in the following applications: PlasticsEurope is committed to encouraging the plastics industry to operate in a safe, healthy and environmentally-responsible manner, and to ensure that plastic products make a positive contribution to people’s safety and health, as well as the environment. [2], In 1954, polypropylene was discovered by Giulio Natta and began to be manufactured in 1957. Polymers are lengthy chain compounds composed of monomers. [57] They enter natural ecosystems from a variety of sources, including cosmetics, clothing, and industrial processes. This category includes both commodity plastics, or standard plastics, and engineering plastics. In 1897, the Hanover, Germany mass printing press owner Wilhelm Krische was commissioned to develop an alternative to blackboards. [45] As of January 2010, the LA Times newspaper reports that the United States FDA is spending $30 million to investigate indications of BPA being linked to cancer. Subsequently, polyamides 6, 10, 11, and 12 have been developed based on monomers which are ring compounds; e.g. Furthermore, if the physical properties of a given plastic do not quite meet the specified requirements, its balance of properties can be modified with the addition of reinforcing fillers, colours, foaming agents, flame retardants, plasticisers, etc., to meet the demands of the specific application. [15], While most plastics are produced from petrochemicals, bioplastics are made substantially from renewable plant materials such: as cellulose and starch. But it also helps recycling collectors determine what items they can accept — and which ones go in the trash. Plastic pollution can be found in all the world's major water bodies – for example, creating garbage patches in all of the world's oceans – and contaminating terrestrial ecosystems. 1900–1975, Material Properties of Plastics – Mechanical, Thermal & Electrical Properties, History of plastics, Society of the Plastics Industry, "A brief history of plastics, natural and synthetic", Timeline of important milestone of plastic injection moulding and plastics, https://en.wikipedia.org/w/index.php?title=Plastic&oldid=999665007, Wikipedia articles needing page number citations from November 2018, Articles with unsourced statements from July 2017, Articles with unsourced statements from December 2019, Articles with unsourced statements from March 2019, Creative Commons Attribution-ShareAlike License. [2] Other uses include automobiles (up to 20% plastic [2]), furniture, and toys. Most plastics are man-made; they do not occur in nature. In this chapter of Synthetic Fibres and Plastics, we will get introduced to the most useful material used daily, that is Plastic! The molecular structure of the repeating unit can be fine tuned to influence specific properties of the polymer. through pushbacks on plastic bans and by increasing the number of products wrapped in plastic in countries, where plastic use is not already as widespread (i.e. In most plastics, the long chain is a chain of carbon atoms with other atoms attached to them. [105] Bakelite was originally used for electrical and mechanical parts, coming into widespread use in consumer goods and jewelry in the 1920s. caprolactam. In contrast, global production of polyethylene (PE) and polypropylene (PP), the world's leading petrochemical derived polyolefins, was estimated at over 150 million tonnes in 2015.[17]. ", "Technical Support Document: Toxicology of Hydrogen Chloride (Revised)", "How can I preserve my family photographs for my grandchildren? Plastic is the most prevalent type of marine debris found in our ocean and Great Lakes. That’s likely because they contain flexible films. [32] Typically fillers are mineral in origin, e.g., chalk. Depending on their chemical composition, plastics and resins have varying properties related to contaminant absorption and adsorption. The manufactured or synthetic plastics are often designed to mimic the properties of natural materials. Oxy-biodegradable means it needs only oxygen (not light or anything else) to break down. 1. Polyvinyl chloride (PVC, commonly called "vinyl") [106] incorporates chlorine atoms. BPA is found in polycarbonate plastics and epoxy resins. Some modes of degradation require that the plastic be exposed at the surface (aerobic), whereas other modes will only be effective, if certain conditions exist in landfill or composting systems (anaerobic). Put simply, single-use plastics are goods that are made primarily from fossil fuel–based chemicals (petrochemicals) and are meant to … [11] Common thermoplastics range from 20,000 to 500,000 amu, while thermosets are assumed to have infinite molecular weight. [46] Bis(2-ethylhexyl) adipate, present in plastic wrap based on PVC, is also of concern, as are the volatile organic compounds present in new car smell. These include microfibers from clothing, microbeads, and plastic pellets (also known as nurdles). In the nineteenth century, as industrial chemistry developed during the Industrial Revolution, many materials were reported. Primary microplastics are any plastic fragments or particles that are already 5.0 mm in size or less before entering the environment. Download a PDF of this page Science of Plastics Definition Plastics are a group of materials, either synthetic or naturally occurring, that may be shaped when soft and then hardened to retain the given shape. Like most other foam plastics, foamed polystyrene can be manufactured in an "open cell" form, in which the foam bubbles are interconnected, as in an absorbent sponge, and "closed cell", in which all the bubbles are distinct, like tiny balloons, as in gas-filled foam insulation and flotation devices. Others are small, privately owned operations. Plastics are used to make bicycle helmets, child safety seats and airbags in automobiles. The European Union has a permanent ban on the use of phthalates in toys. Plastic debris can come in all shapes and sizes, but those that are less than five millimeters in length (or about the size of a sesame seed) are called “microplastics.” If the problem persists, please contact us: info@plasticseurope.org. In addition, plastics can be made in many colors. Sign up for the latest news on plastics and innovation!

The plastics industry was revolutionized in the 1930s, with the announcement of polyamide (PA), far better known by its trade name nylon. They are mostly used in the manufacturing of baby milk bottles, riot shields, plastic toys, sunglasses lenses, and automotive headlamps. Let’s set … They can come from a variety of land and ocean-based sources; enter the water in many ways; and impact the ocean and Great Lakes. Municipal solid waste incinerators also normally include flue gas treatments to reduce pollutants further. We may not think about them often, but versatile plastics inspire countless innovations that help make life better, healthier and safer every day. Prior to the Montreal Protocol, CFCs were commonly used in the manufacture of polystyrene, and as such the production of polystyrene contributed to the depletion of the ozone layer. [16] Due both to the finite limits of the petrochemical reserves and to the threat of global warming, the development of bioplastics is a growing field. Essentially, plastics are human-made, synthetic polymers made from long chains of carbon and other elements. Standards help maintain the quality and safety of products. Nevertheless, this is a developing field. Separating Myth from Fact. Natural rubber is an elastomer (an elastic hydrocarbon polymer) that originally was derived from latex, a milky colloidal suspension found in specialised vessels in some plants. A monomer is a molecule that can be bonded to other identical molecules. The majority of the world’s plastics end up in the garbage, rivers, and eventually in lakes and oceans. Each boasts different "green" properties. Plastics is the term commonly used to describe a wide range of synthetic or semi-synthetic materials that are used in a huge and growing range of applications. Plastic debris can come in all shapes and sizes, but those that are less than five millimeters in length (or about the size of a sesame seed) are called “microplastics.” Examples of such qualities and classes are: thermoplastics and thermosets, conductive polymers, biodegradable plastics and engineering plastics and other plastics with particular structures, such as elastomers. d 2 w® stands for "degrade to water"; after it breaks down, only oxygen, carbon dioxide, and biomass remain. The output of the process (commonly known as cellulose nitrate or pyroxilin) could be dissolved in alcohol and hardened into a transparent and elastic material that could be molded when heated. Get facts about plastics, discover plastics history and read about the diverse types of plastics. Well, at least for me … Plastics Chemistry: How Plastic are Made. The common noun plastic should not be confused with the technical adjective plastic. They may also be used in other consumer goods. The most popular plastics in this category is polycarbonate and polylactide. developing nations)).[29]. Plastic colorants are chemical compounds used to color plastic. In the late 1950s, high impact styrene was introduced, which was not brittle. Examples of thermosetting plastics are silicones, urea aldehyde and Bakelite. Many of the properties of plastics are determined by standards specified by ISO, such as: Many of the properties of plastics are determined by the UL Standards, tests specified by Underwriters Laboratories (UL), such as: Blended into most plastics are additional organic or inorganic compounds. They resist damage by water, heat, chemicals, and electricity.
