The Life Cycle Of A Television
Transcript of The Life Cycle Of A Television
After it is dried, it is overlapped with a layer of silicon dioxide.Then it is coated both front and rear glass surfaces with a very thin layer of indium tin oxide. Then another following layer is added, it is known as light-sensitive material called photoresist, above the indium tin oxide film. Polymer is then added, to align the picture. Polymer is made out of, molecules all together. The final thing is to apply the sealant and injecting the liquid crystal. Sealant is a material used for sealing something so as to make it airtight or watertight. Finally, the glass display is added on and is attached to the circuit boards containing the control and drive electronics. Sound system is also added along with the screen. Bibliography The TVs are transported from the original factory to another factory to be able to be in proper packaging which is more appealing towards consumers. Most of the factories are in Asia. In Asia, the workers put the Televisions in wood boxes and lock it up with some packaging to keep it safe. They do this with all their Televisions and then send them off nearby, where there is a packaging factory. They upload the trucks with the Televisions and send them to the factory. Sometimes they go to factories overseas, but most manufacturing and packaging factories are in Asia, and therefore the televisions are sent within the continent. The packaging is a difficult part of the Televisions life cycle. The reason it is difficult is because the Televisions are delicate, the machines have to handle them with care and make sure that they pack them so that they are safe and don’t get damaged by the time they get to the consumer. If they are damaged while packing it is the packaging companies fault, unless they can prove that it was the transportation that sent it damaged. The Television is first packed with packing film, which protects it. Then Styrofoam is added and cut to be placed on the four sides of the Television, and then the television is put into a large cardboard box, which just fits the television so that it stay compact. After the machines finish packing they are uploaded onto a ship taking them to different countries to retailers for them to be sold to consumers. Consumers go to retailers/stores and buy the Television. They can then watch and use the Television as much as they want. The good thing about Televisions is that they can last a long time. The Television is almost always running in a family. Statistics show that the average time one person would watch TV for is at least 6 hours. There are 24 hours in a day, for 9 of those hours, we’re sleeping, other 6 hours parents are at work, and children are at school, the other 6 hours the family tends to switch the TV and watch TV. This means that the TV is almost always running when the family is at home. The TV is the one product that is used the most among the world, next to computers. After the Television has been used by the household members, there comes a time where the Television has to be disposed. There are two things that can happen depending on the situation. Usually other Televisions are just disposed and they go to the landfill, as the components of the television are mostly plastic, the Television takes time to decompose. Also the metal is still usually in good condition, but now that it’s in the landfill, no-one will ever know. The Television will then just sit in the landfill for years. The alternative way, is to return it back to the manufacturer so that they can recycle the Television. Some of the materials and components of the TV may not be completely damaged or some materials may be able to be recycled and re-used, this way less waste is going to the landfill, and its only parts which really are not useful. Meanwhile the other components which are still in function, which do not need to be disposed, can be used again. This is a great things about my Television, that only some of the TV goes in the landfill, and the rest can be recycled and re-used, and so the Life cycle continues. (LCD Television, 2013) (How Television, 2013) (How Televisions, 2013) (How Liquid, 2013) (How Televisions, 2013) (Danbury, 2013) (LCD, 2013) (Television Watching, 2013) (classroomclipart, 2013) (UNEP, 2013) (Television Recycling, 2013) Throughout the Life Cycle of my Television, there are inputs and outputs which have an impact on the nature and the environment. Starting back with the collection of raw materials. To be able to extract something from the Earth isn’t an easy job. There has to be a machine. The Machine itself has gone through a life cycle, and it needs energy to be able to function too, as a result the output of the machine leads to pollution. Not just air pollution but water pollution too. Air pollution contaminates the air, causing humans to be breathing toxic air, which is extremely harmful to our bodies and lungs. On the other hand, there is water all around the world, even underground near extraction materials, therefore, the pollutants get trapped inside the water, which we then drink. It not us, the animals, and sea life that need water take it in and it causes their death. Just because of this one input, the machine, it causes so much harm towards the environment. No-one knows how to stop this problem, the only way to extract these materials is to mine, and that causes pollution the only thing that can put a stop to this pollution is to stop mining and use different materials. Or, another thing that may work it to take the pollution and the energy generated can be used as electricity. That way the pollution will come in use, but it would still be contaminating the air. The best option would be for scientists to explore and create new chemical substances which work as well as the mining materials.
When it comes to Manufacturing, there is more harm to the environment, because it takes several procedures to be able to create that one television. First they make the housing of the TV. They do this by injecting heated materials into the molds. Heated. Something can only be heated when there is energy traveling through it. Therefore the input is energy. To be able to injected something it must be at a high temperature, high temperature usually leads to smoke. Smoke becomes the output of this phase. The smoke is among one the most dangerous things we can inhale, and can cause our lungs to damage, and start to choke us and animals. Also it can cause smog, which again is a terrible resource of air. It’s when the air is full of fog, and smoke is released, this way the smoke gets trapped inside the fog. Again dangerous for biotic species. One way to stop this from happening, which people are already doing is rather than injecting the materials, create more layers, so that the materials don’t need to be injected, they’re already within the layers. This way this stops smoke from being released. The housing is also made out of plastic, which we humans think of as the best material in the world, but in reality it’s the worst material in the world, and our entire planet will fail with plastic in our existence. The plastic is the input and the output is deaths of animals. Plastic is one thing that doesn’t decompose, therefore it stays there forever littering out world within seconds. When the plastic is lying around, animals are tricked by the bright colours of plastic and they choke and die with it. Not only that but they can get caught on an animal and the animal may not able to move. This causes a decrease in the general animal population. 60% of a television is create of plastic, and that’s only for one Television, what about the other thousands getting made in the factory every second? The way to stop this is to think of a new material for the housing. The materials should be such that it can be recycled. One material which could replace it is glass, because it can be re-used and recycled over and over again. The next thing that they do which harms the environment is that they wash the glass. This may not seem like such a big thing, but in reality, they are not just creating 1 television, they are making thousands, and every single one of their screens has to be washed and cleaned. This is a huge loss it water. The input is water and the output is less clean water for the world. We only have 1% of the Earths water, and if that 1% is being used more to clean glass rather that for people in Africa who don’t get a speck of water, it’s a waste. Water is among the most valuable resource on Earth, and if we don’t use it right, our valuable resource will be gone. We don’t have to wash them, why do they need the water. They can be dry wiped, this way no water will have to be used. But if it really does need to be washed, they can be dipped in water together, rather than being washed individually. Those are the three main things that occur when manufacturing the Television that hurt the environment the most.
The next stage is transportation. Transportation usually occurs throughout the cycle. Extraction materials to manufacturer, finished television to packaging, packaging to retailer, retailer to consumer, and consumer to the landfill. Transportation is basically polluting the air within seconds. It’s usually large trucks which do the transportation. Trucks need petrol, petrol leads to pollution. Again, we faced the same problem. The input is petrol/energy for the truck and the output is more pollution. This is just petrol that will last a week or more depending on the distance, but otherwise that is only for one stack of television, there are thousands of televisions which are still being made, or the materials are still being extracted. There is always going to be a release in pollution which will contaminate the air. The way to solve this problem it to have battery powered trucks. This way they don’t need petrol, and they are running by battery, therefore there is no exhaust and no pollution. The trucks would be running on battery and not be polluting the air around it making it safer for us humans to breathe.
Next is packaging, when packing televisions there is a lot of Styrofoam used along with cardboard. Cardboard is fine, and it great when packing as it can be used again and is biodegradable, whereas Styrofoam on the other hand is not. It stays, similar to plastic, and doesn’t go away. When Styrofoam is thrown away after unwrapping the television, it goes straight to a landfill, and stays there. This causes the landfill to grow, taking more space on Earth, and taking away animals habitats. To stop this from happening is to simply stop using Styrofoam and just use cardboard, as it’s something that is hand and can be used over and over again.
After packing it goes to the retailers, which the consumer then buys, then it’s used. Even us, we are disrupting the environment by just switching it on and using it, onto of that, the written statics before shows that the TV is almost all the time left running. The input is energy/electricity, and the output even more pollution. This happens because of the way we create electricity, we burn coal which releases more pollution. A way to stop this is to have battery powered Televisions. They can get charged by solar power that way we don't run back into the same problem when the battery needs to be charged with electricity.
The last stage, end of life. When we dispose, to the landfill, it will sit there for the rest of its life, and will take years to decompose, and again, this is just one TV, there are still so many more getting disposed every single day, and then they continue to buy even more. The input is throwing away the television, and the output causes landfills to grow and animals habitats be taken away for that extra space. The only way to stop this is to recycle. Send your TV back to the manufacturer so that they can use some materials that aren’t damaged and components that are still in function. That way you will only be throwing out what is necessary and you are recycling everything else that can be recycled. •It allows my family and I to have entertainment 24/7
•It is a product which can be re-used and recycled, specially the components and materials.
•My family and I always have something to do, because there is always something or the other on TV that we can watch and enjoy – Keep you occupied.
•Keeps us updated on information, whether it may be the worldwide news, the weather or traffic.
•It allows us to explore and discover new things with channels such as discovery and national geographic.
•It’s the one thing that can get you to sit as a family.
•There’s something to talk about with you friends and relatives. •It becomes addictive if you watch it to frequently.
•Can cause weight gain and people tend to become more lazy.
•Causes pollution because it uses electricity and coal in burnt.
•You have a larger amount to pay towards the electricity bill
•Mind becomes dull/ absent, because the mind is use to being focused towards TV.
•People spent more time watching TV than working and studying.
•Hurts your eyesight and your vision may become more worse the more you watch it. Integrated Waste Management is waste prevention. It’s when a school company or city disposes of their waste using available methods such as recycling, composting and disposal. The system is among the most effective, as it manages solid waste in ways that is most effective to protect human health and the environment. They separate the materials into group and then from there, they think of the best way to get rid of the waste, whether it is sending it back to the landfill, composting, recycling, re-using or even incineration.
People have started this act because worldwide waste has become an enormous worldwide issue. On average, we throw 4.6 pounds of waste a day, which is equal into 1679 pounds of waste per year, and that’s only for one person. The landfill continues to grow every single second. Not only that, but when we run out of space, we continuously cut down trees, and animals habitats in order to captivate more space. Because this we are taking the shelter of animals, and they are not living in their natural habitat and have to adapt in an environment that they are not use too. In addition, there’s so much waste, that we don’t know where to keep it, so we are putting the waste into the Pacific Ocean. There is a big garbage patch in the middle of the Pacific Ocean. It’s so big; it’s twice the size of Texas. Sooner or Later, because of the oceans current it will move towards Indonesia and Malaysia, and they will be bombarded with a huge garbage patch. Because of all this waste, toxic gasses are being released into the air that we and other organisms take in, for energy and to be able to breathe and live. This is what is ruining our environment, we waste so much without thinking, and don’t bother about what happens to it. How Science Used In The Life Cycle Every is science. Everything around us, is only possible with the help of science. Things that we have created, such as products, electricity, and even pollution. Its thinks that we have done, by putting our minds together in order to create something. It could be using different materials, machinery, or to do with the environment too. Throughout the life cycle of the television, science is used. When extracting the raw materials, the mining machines as a result of science. The machine was created by humans to make tasks easier for us to portray, the negative thing about it is that is is causing pollution. Pollution is also caused by the output of machines which have created by science. Pollution is linked to the environment and how the world is as we know it. Then the manufacturing. The machine which injects the heated materials into the molds,is created because of science. Designers have put their minds together and in order to create the machine to get the function of it right. Science is also used when creating the LCD screen. The liquid crystal is a chemical that is scientifically been made, therefore it is science, because it is a chemical that is man made. Then when it goes to transportation, the trucks need fuel in order to run, and be able to send the television to the appropriate destination. Most petrol that trucks use, have been refined originally being crude oil. Crude oil is natural and can be extracted from the ground, scientific methods help us extract the crude oil from the ground, again linked to science, even though it causes toxic gasses and pollution to be released. Then when it get refined, it is done thanks to scientists, who have tested this and have given us a method to use the natural resource. This then creates petrol which the truck needs in order to run. Then comes the packaging. When packing televisions, you need Styrofoam. Styrofoam is not natural, it is made out of polystyrene. Polystyrene is a petroleum-based plastic made from crude oil. Much like petrol, the crude oil is refined, to create polystyrene which then goes through a manufacturing process using machines created my scientists, to get the final product as Styrofoam. Then the usage, is when we actually use the TV. The Television needs electricity in order to work. Electricity is something that we have created, by burning coal. The only reason we have electricity is because of scientists. They found away that we could use modern day technology at a much faster rate. Electricity is science! Then finally, when it come to disposal, science is finally doing something that helps the environment. Recycle.. We are able to send the television back to the manufacturer so that they can take out components and materials that are not damaged, or just other materials that can be created into something else, such a plastic. Science is allowing us to be able to re-use and recycle products so that less can go into the landfill, not only that but cities have also started Integrated Waste Management, everything else of the television that goes into the landfill can be set out in groups according to the material, and they can be disposed in the best possible way, maybe compost, incineration, more recycling, and if nothing can really be done then the remains go back to the landfill! That way even less of our television is going towards the landfill! The short answer is Yes! Sustainable means to maintain. Televisions are a product that can last for a very long time, of course depending on the brand. The Television is made out of lots of different materials such as plastic and metals. These materials are good, because they can be used over and over again. The television can last for up to 6 years! When it does start to break down, rather than sending it to the landfill, you can send it back to the manufacturer. This way when they receive the TV they can check for anything that can be re-used and recycled to be put into another TV. Things such as components or even materials that are in good condition to be used again. This is how the cycle works, the items keep getting used again and again, so maybe in reality, the TV itself is not so sustainable, but thanks to the TVs components and materials, it really can be! The Stewardship of the manufacturer is similar to the consumers. The Manufacturer is the person who is the one who creates the product, therefore they are the ones who are wasting the water by using it just to clean 1 glass per TV, but there are thousands more which are being created too. Then they also need to be injected with heated materials into the molds, which releases smoke because of the chemical reaction, therefore causing it to trap in the air, which we then breath in, smoke is terrible for our lungs. When they actually create the TV, they have a horrible stewardship role, and are not being a steward of Earth. They are wasting water, causing smoke, and for the factory to be built, cutting trees and habitats of animals. The one thing that they do, that is good, is that they take the television back from the consumer, rather than them throwing to the landfill, and they take the television apart, and see if there are any materials that can be used again rather than being throwing out, or any components that can be fixed and be re-used, therefore they are then being a steward as they are stopping the increase of the landfill by taking the television and seeing what can be recycled and re-used. The Consumer is a slightly better steward of Earth compared to the manufacturer. They are the ones which only do one thing that harms the environment, where as on the other hand the manufacturer is doing more. The only thing that the consumer is doing is using the TV. To be able to use the TV, they need electricity. The way we get electricity is when coal is burnt, and the power is used to run the TV. Because of the coal burning it causes pollution in the air. Our bodies are not meant to inhale pollution, they are meant to inhale oxygen. This is the thing that we are doing which is harming the Earth and the organisms of Earth. The pollution that we create is not a little bit, its a lot. As the statistics before shown, tell us that the TV is almost always left running, which means that there is almost always pollution being creating because the TV is running. But then at the end of life of the television, the consumer gives the television to the manufacturer rather than sending it to the landfill. Therefore they are doing something good, because the are stopping their side of increase of the landfill which could grow so much, that animal habitats may need to be cut down too. So similar to the manufacturer, and the end of life, both the consumer and manufacturer become a stewards of the Earth. The television is a product that is created by the manufacturer. He is the one who is creating the smoke by injection the heated materials, and wasting the water by cleaning the glass. He is harming the environment, because smoke is dangerous as it can get trapped inside the air which we then breathe in. Smoke can also lead to smog, which is when smoke and fog get trapped inside each other the air becomes dirty and dangerous. It also doesn't rise up into the air because of its density, it stay down, and so its becomes harmful for the animals and us humans. Water is among the most valuable resources we have on Earth, without it we are nothing. We depend on water for energy, not only us, but all other biotic species do to. We all need it to grow and need to for strength. We only have 1% of the Earths water, and we are having to share that with 7 billion people, all the animals and species in the world, and plants and nature too! When the manufacturer takes the water from us, the species that really need it to survive, and use it to clean glass for television, it is a waste. They are the ones that are harming the environment by sending pollution out into the atmosphere. The disposal is what they have done. The manufacturer is responsible because they are the ones who have created it and they are the ones who have ruined the environment creating it. The consumer has just payed for it, and is paying to watch television, but the manufacturer is getting payed for ruining the environment and the natural habitats of animals and species, therefore they are the ones who need to take care of the disposal, not the consumer. The consumer should be responsible for the garbage disposal. This is because they are the ones who have chosen to buy the television. They sat and thought, is it the right thing to buy a TV or not. The manufacturer did not force them, it was the consumers own choice. Therefore the TV is the consumers. If the TV is the consumers, then they have to make sure that their TV is disposed and they are responsible, and its their responsibility to save the Earth and re-cycle it, and if they choose not to, and make the wrong decision and send it straight to the landfill, then they are responsible for that, extra amount in the landfill. They are should have the initiative to know the difference between right and wrong, but if they choose to do something wrong, when the product is theirs, then they are responsible. Once the consumer buys the product, it becomes their own property. The manufacturer hasn't done anything, they have just created the TV for the consumer to use and enjoy. By using the electricity the consumer is creating pollution which is terrible for the Earth, so they are the ones who are acting upon the TV, so they should dispose it, and however they may decide, they are responsible. Economic Looking at this world factor, the consumer is responsible again for the disposal of the television. This is because the consumer payed money to be able to own the television.
They legally made the Television theirs by giving the retailer money, to be able to have the product to themselves. They are not paying the manufacturer, so the manufacturer has nothing to do with the TV, as they did not pay for the TV, they are getting payed money to create the TV, otherwise they have no other relation to it. Legally, the TV is for the consumer, it is not the manufacturer because he did not pay for it! As said in Moral/Ethics, the consumer is paying for all of the maintenance and usage for the TV. They pay for the electricity bill of the TV. Meanwhile behind their back, there is coal being burnt for this TV to work and to run, so that it can entertain the consumer and its family. The manufacturer has nothing to do with the usage of the TV, as he is not watching the TV, nor is he paying the bill to run the TV. Again he has nothing to do with the usage. Then when it comes to the disposal, thoughout the whole usage of the TV, the manufacturer hasn't been involved, they haven't payed for anything to do with the TV. The consumer is still the owner of the TV, even when is is disposed, because they payed for it, so the consumer would be responsible of the disposal. •"How liquid crystal display (lcd) is made - material, manufacture, making, used, components, procedure, steps, machine, Raw Materials."

Overall, after looking and exploring 3 different one world factors, I would say that the person who is responsible for the waste disposal is the consumer! I hope that you learned a lot about the life cycle of a television, and how the life cycle affects us and the environment. I hope that you've also learned how serious waste is, and what it is doing to the environment and habitats around us. Next time I hope that you think, before you throw out that plastic water bottle of yours, just like the TV, things can be recycled, so save the Earth, and animals habitats, and make the world a better place
-Kenisha By Kenisha Paliwal
Grade 7 (Ore, 2013) (Garbage, 2013) Stewardship is to take care and manage, a steward of Earth, is someone who take care of Earth, even if it may just be to recycle. It your environmental act on Earth.
