The business of Molded Furniture has marked its place in the country through growth during the last ten years. This growth has opened up new opportunities. The prime reason for this is awareness about the product. Along with that, companies are offering conditional warranty of plastic chairs minimizing risk of customer. Molded Furniture is basically produces in developed countries to be used as Lawn Furniture and outdoor restaurants.

One of the most important plastics processing operations, in terms of variety of products made and amount of material handled, is injection molding. This production method now is being used to manufacture items from practically every known plastic.

Manufacturers in the plastic furniture market are modifying their business strategies to capitalize on the growth of the e-commerce industry as a potential distribution channel, as millennial consumers are highly inclined towards purchasing furniture online.

With the growing awareness about the negative impacts of plastic pollution on the environment, the adoption of recycled plastic materials is expected to increase in the plastic furniture market.

Injection molding is somewhat unusual among production methods in that essentially the entire process in carried out on the injection molding machines were similar in general design to metal die casting machines, but the processing characteristics of plastic have led to change in design & evolution that are still going on. The product injection molded plastic furniture are the products produced by these injection molding machines with varied shape & size along with different colour & shades according to the choice of customers & even according to the pattern as per the modern society such as office culture, drawing rooms of houses, which give style & liking of consumers.

At present, these injection molded plastic furniture frequently used at every mode of the social occasions & places.

The global market for plastic furniture has been witnessing healthy growth with commercial sector accounting for more than one-third share of the market revenues. However, with the increasing growth of the construction industry worldwide, especially in developing countries, the demand for plastic furniture is expected to surge significantly in the residential sector.

Leading manufacturers in the plastic furniture market account for over 45% revenue share of the market. Market leaders are predominantly focusing on expanding distributors’ network and strengthening their geographical foothold in the market.

New entrants and start-ups in the plastic furniture market are concentrating on launching innovative designs and cheaper alternatives to plastic furniture to gain recognition and create brand identity in the market.

A mounting number of small businesses are entering the plastic furniture market with an environmental conscience by launching new designs of plastic furniture made of recycled plastic, in order to capitalize on the growing consumer demand for eco-friendly products.

This type of chair is injection moulded. This manufacturing process is most cost effective for batch produced pieces of furniture. The initial sets up costs are high as expensive equipment is needed. The development and skillful manufacture of a dye (former) is an expensive task. However, if thousands of these type of chair are to be manufactured each chair is relatively cheap. Each chair should be of the same high quality. The modern contemporary materials suit a modern style and environment.

It is intended to prepare a Feasibility Report to install 120000 Nos/Year Plastic Moulded Chairs production facilities as a Green Field Project.

A plastic is any one of a large and varied group of materials, which consists of essential ingredient combination of carbon with oxygen, hydrogen, nitrogen and other organic and inorganic elements. While solid in the finished state, at some stage in its manufacture it has been or can be formed into various shapes by flow-usually through the application singly or together of heat and pressure. They play an important role in the economy of all industrially advanced countries.

Though plastic is a very useful material that is flexible, robust and rigid they become waste after their use and they pollute the atmosphere. To protect the environment as well as to take advantage of plastic, recycling procedure is used. Plastic recycling is the process of reprocessing used scrap and waste plastic into new plastic material. Recycling old plastic products uses 20%-40% less energy than manufacturing it from new. To aid the recycling process, plastics come with plastic identification code to identify the different polymers that are used in the manufacture of plastic.

The demand for plastics depends largely on growth in user segments and overall macro-economic growth. It has been seen that the consumption of polymers is closely linked to the economic development of a country. In this respect, plastics are similar to rubber and driven by the same factors. Thus all used plastics will either go for recycling or land filling. If all plastics could have been recycled, we could reduce our oil consumption and save 25% of our landfill space. Plastics waste recycling is considered to be one of the most viable projects all over the world today.

Developed countries like Japan, Korea, reprocess plastic waste in a big way. There are new techniques introduced every day; however, the polymer industry can develop new grades and types of plastics, that too faster than the recycling equipment industry can develop identification & sorting techniques as well as equipment. There is still much that can be done to improve the collection and infrastructure of the recycling industry. Incentives to increase collection and use of recycled or bio based materials come mainly from legislatively mandated initiatives or from positive business climates (such as dramatic increases in oil prices or consumers demand). There is a very good scope and market potential for recycling. New entrepreneurs should venture into this field.

Reprocessed plastic granules are used to produce packing covers, carry bags, buckets and mugs etc. Hence there is a good scope to recycle used plastic scrap to produce plastic granules, subject to guidelines laid down in Environment Act.

Granules are in demand by various industrial units manufacturing plastic products. There is a good scope for selling plastic granules in any part of the country. Granules of different colours also can be produced with the same equipment by separating waste material by colour.

Plastic recycling refers to the process of recovering waste or scrap plastic and reprocessing the materials into functional and useful products. This activity is known as the plastic recycling process. The goal of recycling plastic is to reduce high rates of plastic pollution while putting less pressure on virgin materials to produce brand new plastic products. This approach helps to conserve resources and diverts plastics from landfills or unintended destinations such as oceans.

The Need for Recycling Plastic

Plastics are durable, lightweight and inexpensive materials. They can readily be moulded into various products which find uses in a plethora of applications. Every year, more than 420 million tons of plastics are manufactured across the globe. Consequently, the reuse, recovery and the recycling of plastics are extremely important.

What Plastics Are Recyclable?

There are six common types of plastics. Following are some typical products you will find for each of plastic:

• PS (Polystyrene) – Example: foam hot drink cups, plastic cutlery, containers, and yogurt.

• PP (Polypropylene) – Example: lunch boxes, take-out food containers, ice cream containers.

• LDPE (Low-density polyethylene) – Example: garbage bins and bags.

• PVC (Polyvinyl chloride)—Example: cordial, juice or squeeze bottles.

• HDPE (High-density polyethylene) – Example: shampoo containers or milk bottles.

• PET (Polyethylene terephthalate) – Example: fruit juice and soft drink bottles.

Looking Ahead

Recycling is critical to effective end-of-life plastic management. Increasing recycling rates have resulted from greater public awareness and the increased effectiveness of recycling operations. Operational efficiency will be supported by ongoing investment in research and development.

Recycling of a greater range of post-consumer plastic products and packaging will further boost recycling and divert more end-of-life plastic wastes from landfills. Industry and policymakers can also help stimulate recycling activity by requiring or incentivizing the use of recycled resin versus virgin plastics.

The global Recycled Plastic market is projected to grow from US $44.03 billion in 2021 to US $76.23 billion in 2028 at a CAGR of 8.2% in forecast period.

It is intended to prepare a Feasibility Report to install a Reprocessed Plastic Granules production facility with an installed capacity of 450000 Kgs/Year as a Green Field Project.

Playing with toys help children learn about the world around them in a much better way. Toys nurtures healthy overall growth in children. It is often said that play is a child's work. Play provides an outlet for children's imagination, creativity and ingenuity. Toys are tools that children use to play. They learn essential skills through their playtime with toys. Communication, fine and gross motor skills, cognition, creativity, problem solving, learning ability and social interaction are a few of the developmental areas that are stimulated by play activities. Toys can be categorized into various groups, depending on the part of the child it helps to stimulate. Here the games have broadly categorized the games into 4 distinct categories.

• Cognitive Toys : Toys that stimulate thinking and problem solving are cognitive toys.

• Physical Toys : Toys that helps in developing the gross and fine motor skills are physical toys.

• Sensory Toys : Toys that stimulate the senses of hearing, smell, touch, sight, and taste are sensory toys.

• Social Toys : Toys that help children to develop social skills and understand emotions are social toys.

Playing with toys is considered to be important when it comes to growing up and learning about the world around us. Younger children use toys to discover their identity, help their bodies grow strong, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults on occasion use toys to form and strengthen social bonds, teach, help in therapy, and to remember and reinforce lessons from their youth.

Toys these days are popular not only among kids, but adults too have entered this field through the medium of sports and games. Many sports and games are played by adults at national and international levels representing their respective countries. Parents too prefer to play with their children in order to interact with the latter and thus engage in board games and other toys with them. The metros and category A towns account for most branded purchases and those that sell at higher price points. Largely, the rest of the market is highly price sensitive and items above ₹ 200 fall in the planned purchase category and not impulse buying. In category C and D towns, unbranded and lower-priced toys are sold at average price points of below₹ 100.

Plastic Classification:

Plastics are classified in several ways. The most accepted division that covers the entire field is by the behaviour pattern.

(1) Thermoplastic

(2) Thermosetting plastics

In this report we are only concerned with Thermoplastics.

Thermoplastics are those which soften under heat and again harden when cooled and this process can be repeated a number of times without any appreciable was in the physical properties.

Plastics today have a prominent place in the spectrum of materials frequently used by materials engineers and designers. They have earned this placed on the basis of performance at a price, plus the apparently unlimited ability of the plastics industry to develop new plastics or new grades of older plastics to meet specific needs of modern industry. With this status and the tremendous growth of new uses has come an important need for meaningful data on fundamental plastics behaviour under realistic stresses and strains, couched in engineering terms, in short, engineering properties as contrasted with data sheet properties. Needed are engineering criteria for rigidity, strength, endurance and temperature range, which are common to nearly all plastic applications, as well as more specialized performance characteristics that are important only in certain types of special product (eg. electrical properties).

Among the plastics the various industrial grade plastic waste available, the following are the materials like A.B.S. (Acrylonitrite Butadiene) styrones, polypropylene, HIPS, L.D.P.E., L.I.D.P.E. Polystyrene, Opp. OPS and Acrylic. In this report we have considered Ten Industrial grade plastic waste material and for that plastic granules will be prepared.

Nowadays, PET bottles are the global number one in beverage packaging. More than 400 billion plastic bottles come on the market every year and PET is becoming increasingly valuable as a recyclable raw material used in the production of beverage bottles. Thus, it is important that all of the production steps applied for the manufacture of your PET bottles are made sustainable for the future.

The gentle treatment of resources and economical use of materials are a must when it comes to sustainable production. Valuable raw materials such as PET must be processed as efficiently as possible while still tapping into every way of saving costs. The PET manufacturing and production process allows for the application of a sustainable approach which can optimally combine environmental awareness and cost effectiveness: the bottle-to-bottle recycling concept.

Bottle-to-bottle recycling plant efficiently recycles used PET bottles and the recyclate is then reused in the food and beverage industry as recycled PET (rPET). The complete process comprises the cleaning of the used PET bottles and the treatment of the recyclate so that the end product - which could come in the form of flakes, pellets or preforms - can meet the highest quality requirements after the recycling process. European and American certificates (e.g. FDA), and a number of different corporate approvals, all confirm the high quality of the recyclate for direct use in containers which come into direct contact with foodstuffs.

• Food-grade PET flakes and pellets

Recycling plant produces food-grade PET. With it, returned PET bottles can be reused to make new PET bottles. The use of recyclate has clear economic and ecological benefits.

• Flakes, pellets or performs

The procedure gives you the freedom to decide which end product you wish to create. The decontamination step required for the material's later contact with foodstuffs is only ever performed with flakes. Afterwards, the flakes are either used directly or are made into pellets. Another extremely energy-efficient use for the decontaminated flakes is the direct feeding of the material into an extrusion process –

Worldwide, PET-bottles more and more replace glass bottles in the beverage and food sector. The success of PET in comparison to glass is based on several economic (and environmental) advantages.

On the one hand, the production of PET is less expensive and energy consuming than the production of glass. Secondly, the light weight of the PET-bottle makes it easier for merchants and consumers to handle the bottles and crates. It saves energy during transport, particularly on long distance haulage. Finally, PET offers more or less the same material properties as glass regarding hygiene, taste and gas impermeability.

The negative impacts of PET-bottles in recent years result from their use as nonreturnable beverage containers leading to a dramatic increase of beverage container waste. But even here, changes are on the move, particularly in industrialized countries, where PET-bottles enter more and more the existing returning and refilling schemes. Apart from returning and refilling, recycling of used PET-bottles is also possible and will be an interesting option especially for developing countries, where refilling schemes are not in place or economically unfavourable.

A process design is proposed which involves pyrolysis of plastic waste and used tires, activation of the solid residue, partial combustion of liquid to produce carbon black and the use of high BTU gas for process heat. The activation of the solid residue is done using CO2 which produces CO and activated carbon.

The CO2 is regenerated and the lost carbon is recovered using the boudouard reaction to produce CO2 and finely divided carbons. The latter material may be used as a substitute for carbon black.

For many years, various methods are tried and tested for processing of waste plastic. The plastic materials are recycled and low value products are prepared. Plastic materials which cannot be recycled are usually dumped into undesirable landfill.

Worldwide almost 20% of the waste stream is plastic, most of which still ends up in landfill or at worst it is incinerated. This is a terrible waste of a valuable resource containing a high level of latent energy.

In recent year this practice has become less and less desirable due to opposition from Government and environmentally conscious community groups. The value of plastics going to landfill is showing a marginal reduction despite extensive community awareness and education programs.

Research Centre for Fuel Generation (RCFG) has conducted successful 300 successful pilot trials and commercial trials for conversion of waste plastic materials into high grade industrial fuel. The system uses liquefaction, pyrolysis and the catalytic breakdown of plastic materials and conversion into industrial fuel and gases. The system can handle the majority of plastic materials that are currently being sent to landfill or which have a low recycle value.

Catalytic conversion of waste plastic into high value product is a superior method of reusing this valuable resource.

The distillate fuel is an excellent fuel and can be used for

1) Diesel electrical generators
2) Diesel burners / stoves
3) Boilers
4) Hot air generators
5) Hot water generators
6) Diesel pumps

The distillate can be further fractionated into fuels as under and can be used in automobiles.

1) Petrol
2) Kerosene
3) Diesel

Crude oil, Petroleum Gases and Activated Carbon are the product of waste plastic.

The term Activated carbon, active carbon, or active charcoal is usually applied to amorphous carbons possessing higher absorption capacities than wood or animal charcoal. Many processes were developed during world war for the production of effective absorbents for use in gas masks. Industrial activated carbons in the form of pellets, granules or fine powders, and with many industrial applications, are now available in the market under different trade names.

Commercial absorbent carbons may be grouped into decolorizing, gas absorbent, metal absorbent, and medicinal carbons according to their physical structure, properties and applications. No one type of carbon can be used for all purposes. A large variety of raw materials are available for the manufacture of these products. Coal, petroleum coke and wood charcoal are activated by gas activation. Industrial waste e.g. raw dust, begasse, molasses, straw, coconut pericarp and shell, corn cobs, paddy and ground nut husk, corn bean shell, distillery slop, waste Mahua flowers, waste wood pulp laquor and mud from sugar factories have been utilized for the production of active carbons by chemical activation.

DECOLORISING CARBONS

Decolorising carbons are manufactured by gas activation, in which the raw materials are first carbonized and the resulting charcoal heated to a high temperature in an oxidizing atmosphere Chemical activation in which the raw materials are impregnated with a chemical extruded and carbonized and deposition of carbon on porous inorganic base activation is needed in this case.

In the gas activation process, the raw material is carbonized under controlled conditions in closed retorts, the resulting charcoal is crushed, screened and heated in a second retort at 1000oC for 10 to 12 hours in an atmosphere of air, carbon dioxide, chlorine, super heated steam or a mixture of steam and air. Raw materials which do not possess the necessary density and structure for direct conversion are briquetted prior to carbonization. Prebriquetting gives a higher yield and a better product. In the process for the direct conversion of coal to activated carbon the crushed-materials, screened to 11/8 in pieces, is carbonized at 450o - 500oC and steam activated at 950o in continuous vertical retorts, the yield is about 12 1/2% of the coal taken.

For activation by chemical treatment, the raw material is ground and formed into paste with chemicals, e.g. chloride of zinc, calcium and magnesium, alkalies, sulphuric acid, phosphoric acid, sodium, silicate, boric acid, potassium sulphide, lime, ferric chloride, or potassium thiocynate. The paste is extruded under pressure dried and carbonized in gas retorts at about 1000oC. The charcoal is cooled, washed with hydrochloric acid and water to remove inorganic residues and finally dried at about 300oC. A fluidization technique has been developed in France for the production of activated carbon.

The third process gives a product with a porous structure and appreciable mechanical strength. The raw materials viz saw dust, sea weed, peat molasses etc. is mixed with a insoluble salts and the mixture is strongly heated. The carbon gets deposited on the porous inorgenic base. A similar product is obtained when a high ash vegetable product, such as paddy husk, containing an appreciable percentage of silica is carbonized.

GAS ABSORBENT CARBONS

Gas and vapour absorbent carbons are obtained by carbonizing coconut shells, apricot stones, vegetable ivory and anthracit. In recent years, methods have been developed for using softer materials which are rendered hard and dense by briquetting. The carbons are gas activated. A preparation useful for gas masks has been obtained by chlorinate bituminous coal (6-20) mesh until a 100% increased in weight takes place, pelleting and chlorinated material with hydrolyzed starch as binder, baking, crushed and powdered to (8-20) mesh and steam activated at 800oC. Gas absorbent carbons are available in granular form of specified mesh range, e.g. 4 x 6, 412, 20, i.e. retained on 6- and 20 mesh sieve and passing through 4.12 mesh sieve.

METAL ABSORBENT CHARS

Metal absorbent chars are prepared by alkali activation. Structurally, they are identical with decolorizing carbons and are converted into the lather by acid treatment. An active product is obtained by heating bone charcoal with alkali at 850oC. The product obtained is negative changed material and important of its metal absorbing power. It however, possesses the properties of a decolorizing char. Treatment of flocculated material with alkali does not restore the metal absorbent properly.

MEDICINAL CARBONS

Activated carbon finds application in the preparation of pills and digestive tablets. Its absorptive properties are utilized in the treatment of the stomach due to hyper acidity. It removes toxic amines, organic acids of decomposed foods and probably also bacteria from the intestinal tract and many other purposes.

The origin of toys is prehistoric; dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are readily found at archaeological sites. The origin of the word "toy" is unknown, but it is believed that it was first used in the 14th century. Toys are mainly made for children. The oldest known doll toy is thought to be 4,000 years old.

Playing with toys is considered to be important when it comes to growing up and learning about the world around us. Younger children use toys to discover their identity, help their bodies grow strong, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults on occasion use toys to form and strengthen social bonds, teach, help in therapy, and to remember and reinforce lessons from their youth.
The very word toy makes you remind of your childhood. The toys are categorized into many in India and the plastic toys have a market share of nearly 80% of the total toy industry in the country. Other types of toys available in the market are fabric toys, paper toys, and wooden toys, metal toys and DIY toys (containing arts and craft toys) that are manufactured mostly by the cottage industry. However, out of these the metal toys are considered to be sharp toys which are harmful for children and a hindrance in their safety, that is why these toys are known to be slowly loosing it's popularity. Another popular category of toys seen today are educational toys and activity toys which help build the mind and body of the child, then there are soft toys, Electronic toys, battery operated toys and board games like chess and monopoly. There are different types of Electronic toys available in the market. Electronic toys with or remote, walkie talkie sets for kids, toy radios, musical toys, hand-held video games, video games used with T.V, Arcade entertainment products, educational toys etc are popular among Indian children. This report is about a remote controlled car toy. There are a number of Remote controlled Toys in the market. These, include Cars, trucks, playing machines and other equipments. There are differences in the mechanical assembly of these types of toys but the basic Electronic principle is the same. These types of toys have four main units i.e., Transmitter, Receiver, Motor and Power Source. The transmitter sends radio wave which is received by the receiver which is fitted with an antenna. These signals are used to activate the motor. The power source is typically a rechargeable battery pack, but sometimes it's just normal batteries.

India’s urban population is the second largest in the word—larger than the combined urban populations of all countries except China, the US and Russia. India has more than 800 Indian toys and games manufacturers, suppliers and exporters, most of who hail from the unorganized sector. The Indian toy industry, fuelled by the vast domestic market, has now turned its attention to global markets and is fast gearing up to meet international standards and demands.

The Indian toy industry is driven by skilled workforce, diverse product range, growing innovation and creativity, and emphasis on technology-driven learning and education. It is set to grow at 25 per cent in the coming years and is beginning to export to a few developed nations around the world. The worldwide market for toys is huge and offers a plethora of potential for companies to pursue. But the interests of children, who are the primary consumers for toys, are changing faster than ever. Toy manufacturers have to create innovative toys to capture their interests.

Toys these days are popular not only among kids, but adults too have entered this field through the medium of sports and games. Many sports and games are played by adults at national and international levels representing their respective countries. Parents too prefer to play with their children in order to interact with the latter and thus engage in board games and other toys with them. The metros and category A towns account for most branded purchases and those that sell at higher price points. Largely, the rest of the market is highly price sensitive and items above ₹ 200 fall in the planned purchase category and not impulse buying. In category C and D towns, unbranded and lower-priced toys are sold at average price points of below₹ 100. However, the scene in India is changing very fast and there is enough scope for more number of players in the field.

The Indian middle class is prospering and even the 20% of the Indian population which is considered as the middle class constitute a huge market for any product/service. India’s urban population is the second largest in the world, greater than the combined urban populations of all countries except China, the US and Russia. India has over 800 Indian toys and games manufacturers, exporters and suppliers. Most of the Toy manufacturers in India are from the unorganized sector. Mattel Toys, Funskool & Lego are a few International players in the Indian toy industry. The Indian toy industry, fueled by the vast domestic market, has now turned its attention to global markets and is fast gearing up to meet international demands. The strong points of Indian toy industry are skilled workforce, diverse range, focus on innovation and creativity, and emphasis on learning and education. Indian manufacturers are catering to both large and small volume requirements and are exporting to few of the most developed nations. Indian toy industry set to grow at 25% in the coming years.

Worldwide, the market for toys is huge and offers immense potential for companies to pursue. But the interests of children, who are the primary consumers for toys, are changing faster than ever, toy manufacturers have to create innovative toys to capture their interests. Toys these days are popular not only with kids but adults have also entered this field through the medium of sports and games. Today many sports and games are played by the adults at national and international levels representing their country. Parents, now-a days also prefer to play with their child in order to interact well with the child So, they are seen to playing boards games and other toys with their children 5 The Indian market is slightly different from that of overseas, where toys are bought as a child's development aid, i.e. they are considered to be equivalent to books. But in India the scene is slightly different. Unlike other developed economies amount of toys spent per child in India is very low. The metros and 'A' category town account for most of the branded purchase and sell even at higher price points. Largely the rest of the market is highly price sensitive and items above Rs.200 results in planned purchase and not in the impulse buying. In C and D category towns, unbranded and lower priced toys are sold at average price points below Rs.100. However, the scene in India is changing very fast and there is enough scope for more number of players in the field. The Indian toy industry today faces stiff competition from toy manufacturers in China or Chinese toys. Manufactures of toys in India have repeatedly been raising this issue with the Indian Government since it has become increasingly difficult to compete with China toy manufacturers. Chinese toys are available at a lower cost compared to Indian toys.

Basic Ingredient of plastic is-

The major chemical elements making up petroleum are oxygen (O), hydrogen (H), and carbon(C)."

Petroleum is decomposed under heat into gasoline, kerosene, naphtha, light oil, heavy oil, etc. Most plastics use naphtha as main raw material. Naphtha is further decomposed thermally and separated utilizing the difference in the boiling point (temperature at which the phase change from liquid to gas occurs) to form ethylene and propylene, which are the raw materials for plastics. However, many of these gases and liquids are not ready for use as they are.

About "mono" and "poly"

To produce a high-molecular compound, it is necessary to first produce low-molecular compounds and bond them together. This reaction is known as polymerization, the low-molecular compounds as “monomers," and the high-molecular-weight substance as a " high-molecular compound" or "polymer." The word "mono" means "single" while "poly" means "multiple."

The formation of polymers from monomers uses heat, light, and additives such as enzymes (polymerization initiators). In this way, ethylene and propylene, which are monomers, are polymerized into polyethylene and polypropylene.

Simply stated, the " high-molecular substances" as referred to by the Japan Industrial Standard mean " substances with very high-molecular weights synthesized chemically." Substances are classified into low-molecular, intermediate-molecular, and high-molecular substances according to their molecular weights. For example, the molecular weight of oxygen is 32 and that of sugar is 342.

On the other hand, the molecular weights of rubber and proteins exceed 10000. Natural "high-moleculara?? compounds include, natural resins such as natural rubber and rosin, cellulose, silk, proteins, and many other substances. The substances produced in imitation of these substances are synthetic rubber, synthetic resins, and synthetic fiber. Thus, plastics are high-molecular compounds produced artificially. They are called " synthetic resin" or simply " resin" in comparison to natural resin.

The definition of plastics

The Japan Industrial Standard (JIS K 9600-1977) defines "plastics" as "solids artificially formed into useful shapes using high-molecular substances as main raw materials. However, fiber, rubber, paints, and adhesives are excluded."

Plastics, materials made up of large, organic (carbon-containing) molecules thatcan be formed into a variety of products. The molecules that compose plastics arelong carbon chains that give plastics many of their useful properties. In general,materials that are made up of long, chainlike molecules are called polymers. The word plastic is derived from the words plasticus (Latin for “capable of molding”) and plastikos (Greek “to mold,” or “fit for molding”).

Plastics can be made hard asstone, strong as steel, transparent as glass, light as wood, and elastic as rubber.Plastics are also lightweight, waterproof, chemical resistant, and produced inalmost any color. More than 50 families of plastics have been produced, and newtypes are currently under development.

It is very difficult to realise how important plastics have become to our everyday lives. We always seem to have known these materials, and we tend to take it for granted that they occur every day and all around us, for example in our clothing, the pen that we write with, the chair that we sit on or the wrapping of the food that we eat.

So it is sometimes hard to believe that plastics have only been commonly available for about the last one hundred years. Yet in this time the impact that they have made upon the quality of our lives and on the products that we have access to has been enormous. Plastics give us the possibility of manufacturing well-designed, beautiful products from the very many different types of plastics materials that are commonly available today. Within manufacturing technology there is a very high degree of technological understanding of plastics and a range of sophisticated technological processes that enable us to make them and shape them in numerous ways. This book aims to show you a little of what can be done.

The word plastic itself comes from the Greek word plasticos, which means to be able to be shaped or moulded by heat. As we will see, shaping plastics by using heat is a basic part of nearly all plastics manufacturing processes. Like timbers, which can be divided into hardwoods and softwoods, and metals that can be divided into ferrous and nonferrous metals, plastics can also be divided into categories:

Natural plastics - these are naturally occurring materials that can be said to be plastics because they can be shaped and moulded by heat. An example of this is amber, which is a form of fossilised pine tree resin and is often used in jewellery manufacture.

Semi synthetic plastics - these are made from naturally occurring materials that have been modified or changed but mixing other materials with them. An example of this is cellulose acetate, which is a reaction of cellulose fibre and acetic acid and is used to make cinema film.

Synthetic plastics - these are materials that are derived from breaking down, or ’cracking’ carbon based materials, usually crude oil, coal or gas, so that their molecular structure changes. This is generally done in petrochemical refineries under heat and pressure, and is the first of the manufacturing processes that is required to produce most of our present day, commonly occurring plastics.

Synthetic and semi synthetic plastics can be further divided into two other categories. These two categories are defined by the ways in which different plastics react when heated.

Wood–plastic composites (WPCs) are a form of composite combining wood-based elements with polymers. The processes for manufacturing WPCs include extrusion, injection molding, and compression molding or thermoforming (pressing). Newer manufacturing processes for WPCs include additive manufacturing via fused layer modeling and laser sintering. An important constraint for polymers used in WPCs is requiring process conditions (melt temperature, pressure) that will not thermally degrade the wood filler. Wood degrades around 220 °C; thus, general-purpose polymers like polyethylene and poly vinyl chloride are typically used for manufacturing WPCs. Wood fibers are inherently hydrophilic because of the hydroxyl groups contained in the cellulose and hemicellulose molecular chains. Thus, modification of the wood fiber via chemical or physical treatments is very critical to making improved WPCs. The most abundant profiles made from wood–plastic composites are boards or lumber used in outdoor decking applications. Although early WPC products were mainly extruded for profiled sections, nowadays, many injected parts made of WPC are being introduced for various industries, including electrical casings, packaging, daily living supplies, and civil engineering applications. Mold and mildew and color fading of WPCs tend to be the durability issues of prime importance for WPCs. Most recent research on WPC durability focuses on studies to better understand the mechanisms contributing to various degradation issues as well as methods to improve durability. Most WPC products in the USA are utilized in building materials with few exceptions for residential and commercial building applications, which means that building codes are the most important national rules for the WPC manufacturers. New developments are being made especially in
the area of nano additives for WPCs including nanocellulose. Recently, the trend of patent registrations for WPCs has shifted to new products or applications instead of the materials itself.

Plastic recycling includes taking any type of plastic, sorting it into different polymers and then chipping it and then melting it down into pellets. After this stage, it can then be used to make items of any sort such as plastic chairs and tables. Soft plastics are also recycled such as polyethylene film and bags. This closed-loop operation has taken place since the 1970s and has made the production of some plastic products amongst the most efficient operations today.

Compared with lucrative recycling of metal and similar to the low value of glass, plastic polymers recycling is often more challenging because of low density and low value. There are also numerous technical hurdles to overcome when recycling plastic.

A macro molecule interacts with its environment along its entire length, so total energy involved in mixing it is largely due to the product side stoichiometry. Heating alone is not enough to dissolve such a large molecule, so plastics must often be of nearly identical composition to mix efficiently.

In 2013, the global market for polypropylene was about 55 million tones. Polypropylene is the world's second-most widely produced synthetic plastic, after polyethylene.

Polypropylene is in many aspects similar to polyethylene, especially in solution behaviour and electrical properties. The additionally present methyl group improves mechanical properties and thermal resistance, while the chemical resistance decreases.: The properties of polypropylene depend on the molecular weight and molecular weight distribution, crystallinity, type and proportion of comonomer (if used) and the isotacticity. In isotactic polypropylene, for example, the CH3 groups are oriented on one side of the carbon backbone. This creates a greater degree of crystallinity and results in a stiffer material that is more resistant to creep than both atactic polypropylene and polyethylene.
Mat and matting industry is well established in India. Previously it was made from vegetable origin like coconut fibers, jute and cotton fibers etc. Woven fabrics were among the earliest bases used for laminating. They provide a  stronger  and  more impact resistant product. In woven fabrics the fibrous  structure is stronger because the individual fibers are longer by virtue of spinning into yarn. Continuous filament yarns of plastics are much tougher than conventional yarns of vegetable origin. The continuous filament fabrics produce tough  structure  that  are often  difficult  to  bond because the surface  of  the  extruded filament  is  smooth, the individual filaments  are in maximum geometrical  close  packing,  and  there are no ends to the filaments to provide mechanical anchoring.

After the availability of PP and HDPE as commercial plastic raw materials, the  plastic mats have been replacing the conventional mats. Plastic mats are made in a large variety of patterns and designs to provide attractive and damp-proof floor covering. These are preferred over jute or coir mats due to cheap, light, durable and attractive designs.

Now - a - days plastic mats are woven with PP/HDPE yarn  or strapping’s.  The  warp yarns are held in two frames which alternately go up and down and a weft is passed between the  warp every  time  they  move. The matting is dove plain or  stripped according  as the warp is of one colour or of different  colours. It may be woven in various attractive designs.
The weaving pattern of the fabric controls the physical nature of the laminate. A very common weave is a square pattern in which each warp yarn passes above and below each alternate fill yarn during weaving. This gives a structure with  maximum crimp.  In drills and twills each yarn still has considerable crimp as it passes from one side of the fabric to the other. Such weaves exhibit uniform properties in the crosswise and lengthwise directions but are relatively weak owing to the great  crimp  in each yarn.
