ReplyDelete1) By recycling one aluminum can, it saves enough energy to run a television for three hours or to burn a 100-watt light bulb for four hours.
ReplyDelete2) Thus without realize,we actually help world to saves energy,money and natural resources
3) By recycling aluminum cans, it also reduces the pressure on landfill sites.
4) Thus we can make more campaign in campus to make student more realize that important to recycle even a aluminum can only.
5) Not only can aluminum but we can also recycle the paper, box, and also plastic bag.
6)By recycle the aluminum can, manufacturers make new products such as new beverage cans, pie pans, license plate frames, and aluminum foil.
7)Thus we will buy that products again and recycle again, so we will be hero or heroin because we saves our world without we noticed..=)

According to my discussion about the recycling aluminium tin that collected in campus, there is a few ideas based on the related key point given:
ReplyDelete1) To produce the new aluminium tin,it just required 5% energy only and the rest came from the recycle aluminium.
- Aluminium cans recycling create 97% less water pollution than producing new metal from ore.
2) If the aluminium cans were recycled,it will saving energy equivalent of entire gas of consumption for one day.
3) The renewable product that can be produce after the recycling process is aluminium containers,lawn furniture,small appliances, aircraft and etc.
4) After studies for this situation given, I can described that aluminium tin is 100% recyclable and have materials that most widely used non - ferrous metal. This recycling method also can reducing litter,reducing landfill and greenhouse gas emissions.

Recycling is an important part of a sustainable lifestyle. It’s important for the future of the planet that we all live sustainability,in other words make the best use of limited natural resources.Five billion aluminium drink cans are sold in the UK every year and each one could be recycled over and over again, saving energy, raw materials and waste.Why we bother recycling aluminium?
ReplyDelete1- LESS ENERGY
Recycling aluminium drink cans is far less energy intensive. Recycling aluminium requires only 5% of the energy and produces only 5% of the CO2 emissions as compared with primary production.
A recycled aluminium can saves enough energy to run a television for three hours.
2-EASY TO RECYCLE
Aluminium cans are one of the easiest materials to recycle. New drinks cans appear on the shelf just six weeks after recycling.
3-LESS RAW MATERIALS
Recycling aluminium reduces the need to mine bauxite, which, as we have seen, can have negative consequences for the surrounding areas and the people living there.
4-COST EFFECTIVE
Aluminium can be recycled indefinitely, as reprocessing does not damage its structure. Aluminium is also the most cost-effective material to recycle.
5-LESS LANDFILL
If all of these cans were recycled there would be 14 million fewer dustbins emptied into the country’s landfill sites every year.
6-REDUCE POLLUTION
Aluminum recycling can reduce air pollution by 95%. It can save 90% to 95% of the energy required to manufacture aluminum from recycled aluminum cans than from aluminum core.If each person recycles one aluminum can in each month, 1,750 to 3,500 gallons of gas can be saved.
Actually,besides recycling tin aluminium in uniKL MITEC,we also can recycling paper,transform used paper to other used things.Example from paper to bookmarks or else. RECYCLE CAN SAVE OUR WORLD.PEACE.

Sustainable design is the philosophy of designing physical objects, the built environment, and services which is have to follow with the principles of economic, social, and ecological sustainability. Besides that, it also called as also environmental design, environmentally sustainable design and others.
ReplyDelete1) One (1) of methods of conserving energy and water resources is by recycling or reused the existing material such as aluminum tins.
2) Aluminum recycling is a very efficient process which the manufacturers can melt down and reuse aluminum from reclaimed containers repeatedly with little loss in quality. By recycling or reused the aluminum tins, it only uses 8 Btus (British Thermal Unit) per ton which is energy saving of 96% compare with produce it from the raw sources Bauxite about uses 229 British Thermal Unit (BTU).
3) According to the Aluminum Association, creating an aluminum can out of recycled materials needs only 5 percent as much energy as creating a brand new can from bauxite. Recycling aluminum tin only uses about 5% of the energy required to produce aluminum from bauxite, because the latter need a lot of electrical energy to electrolyze aluminum oxide into aluminum. In addition, recycled aluminum saves 95% of the greenhouse gas emission compare from the primary aluminum production.
4) The EPA estimates that recycling one ton of aluminum saves the equivalent of almost 32 barrels of oil, significantly reducing the carbon footprint of the manufacturing process.
5) Universiti Kuala Lumpur Mitec also can look for opportunity for reused or recycling of existing material by provide recycle trash bin at the area of campus.
6) Universiti Kuala Lumpur Mitec also can launch the day or month of 3R (reduce, reuse and recycle) who focus on importance of recycling and reused material which can give the impact to the health and environment in order to increase the students’ awareness.
7) There are a few of renewable resources other than aluminum tins namely glass, paper, box, bottles. Plastic is one of non –renewable resource.
8) After being collected, tins are generally recycled into new tins. After being selected, tins are baled and sold to aluminum manufacturers. Old tins material is refined and melted into ingots or solid metal blocks. Tins manufacturers melt the ingots into sheets of metal, which are then cut and formed into new tins. Next to the beverage industry, the automotive industry provides the biggest market for aluminum scrap. Higher demand for lightweight, fuel-efficient cars means a rising demand for recycled aluminum, which is used in die casts. There are many other uses for recycled aluminum and it also can be sold to other countries for use.
9) From points above, I can conclude that, the recycle and renewable material can save much energy and making Earth better. It exposes me about the importance of protect the Earth for our next/ future generation. I also can use the material over and over again without need to buy the new one. Besides that, I also can generate the income by using recycle material / product maybe… ;)

1. can be sell that mean can reduce to make can again.
ReplyDelete2. can reduce use of dustbin, not full with aluminum cans.
3. the aluminum cans, can be reuse again like be ashtray that use in toilet.
4. based in this site http://your.kingcounty.gov/solidwaste/garbage-recycling/aluminum.asp
Recycling one aluminum can saves energy to power a television for 3 hours.
5. at landfill King Conty over 173 million aluminum cans were disposed. That save energy to power the television for 59,528 years.

ReplyDeleteBenefits of recycling aluminum cans
(1) Recycling aluminum cans saves precious natural resources, energy, time and money – all for a good cause – helping out the earth, as well as the economy and local communities.
(2) Aluminum cans are unique in that in 60 days a can is recycled, turned into a new can & back on store shelves.
(3) Aluminum is a sustainable metal and can be recycled over and over again
(4) Aluminum cans have amazing strength. Four six-packs (24 cans) can hold a 4,000-pound aluminum-bodied sedan.
(5)
Recycling 1 ton of aluminum saves the equivalent in energy of 2,350 gallons of gasoline. This is equivalent to the amount of electricity used by the typical home over a period of 10 years.
(6)
Aluminum cans distinguish themselves as the most recycled and most recyclable beverage container in the world. An awesome 105,784 cans are recycled every minute nationwide
(7)Using recycled aluminum beverage cans to produce new cans allows the aluminum can industry to make up to 20 times more cans for the same amount of energy.
(57274210083)
Recycling scrap aluminum requires only 5% of the energy used to make new aluminum. The nature of aluminum makes the material one of the few "infinitely recyclable" materials used in society; it can be recycled infinitely with no loss in quality. For this reason, approximately 31% of all aluminum produced in the United States comes from recycled scrap and 75% of all aluminum produced since 1888 is still in use today.
ReplyDeleteThe really great news is that aluminum is a material that can be recycled over and over again creating new products from the old without degrading its quality. Saving manufacturers money and in turn, saving you money, AND helping the environment in the process. A common practice since the early 1900s and extensively capitalized during World War II, aluminum recycling is not new. It was, however, a low-profile activity until the late 1960s when the exploding popularity of aluminum beverage cans finally placed recycling into the public consciousness.
Renewable product after the recycling process of aluminum can could be many :
-Sources include aircraft, automobiles, bicycles, boats, computers, cookware, gutters, siding, wire, pan, pot, patio furniture and many other products that require a strong light weight material or a material with high thermal conductivity. As recycling does not damage the metal's structure, aluminum can be recycled indefinitely and still be used to produce any product for which new aluminum could have been used.
Environmental saving :If energy directly equated to carbon dioxide, then recycled aluminum could be said to create 5% of the carbon dioxide produced in the creation from raw materials. In practice, this cannot be assumed. Electrolysis can be done by electricity from non-fossil-fuel sources, such as nuclear, geothermal, hydroelectric, or solar. Aluminum production is attracted to sources of cheap electricity. Canada, Brazil, Norway, and Venezuela have 61 to 99% hydroelectric power, and are major aluminum producers
Each ton of aluminum cans requires 5 tons of bauxite ore to be strip-mined, crushed, washed, and refined into alumina before it is smelted, creating about 5 tons of caustic red mud residues which can seep into surface and groundwater..
End use of material
LOOK FOR 3R HIERARCHY: reduce,reuse,recycle
- Reducing what we have used and recycling all these materials reduces the need to dig up or mine new raw materials, which always damages the surrounding environment
- Making new aluminum cans from recycled cans uses 20 times less energy than making cans from the raw material.
- Recycling 1 ton of aluminums saves 4 tones of bauxite
- 1 recycled tin can would save enough energy to power a television for 3 hours.
- Using recycled materials reduces the amount of energy and reduces the amount of materials we have to dig out!

Aluminum is everywhere. We see it in soft drink cans,pie plates, foil, packaging, siding, gutters, and more. What most people don’t realize is that aluminum is practically the perfect recyclable material. Out of the most common recyclable materials that clutter up our landfills—glass, paper, metals, cardboard, plastics—aluminum is the only material that’s endlessly recyclable, 100% recyclable, and that pays for itself. Here are some other interesting facts I bet you don’t know about aluminum recycling:
ReplyDelete(1) It takes energy to make aluminum from scratch. The energy you save by recycling a single aluminum can will run a TV for three hours.
(2) In fact, it takes 95% less energy to make aluminum from bauxite ore than to recycle old aluminum into new.
(3) Aluminum beverage cans are getting lighter. Twenty years ago, a pound of aluminum made about twenty cans. Today, the same amount of aluminum makes approximately thirty cans. The thickness of the side of an aluminum can is about the same as that of a human hair.
(4) It takes about 400 years for aluminum to break down naturally. That Coke can you just drank from will probably still look about the same in another century or two.
(5) With all the industries that use aluminum—in manufacturing, in packaging, in cars and airplanes—the industry that uses the most aluminum is the beverage industry.
(6) In 2004, Americans recycled enough aluminum to build thirteen aircraft carriers.
(7) Every three months, Americans discard enough aluminum to completely rebuild every single commercial airplane in America.
(8) Approximately 350,000 aluminum cans are made in a minute.
(9) Aluminum can be recycled over and over without breaking down. In theory, we have an inexhaustible supply of it in circulation right now. If we recycled all our aluminum, we’d never have to make more.
(10) The average American discarded fourteen and a half pounds of aluminum just from packaging last year—and almost three pounds of aluminum foil. That’s not even counting aluminum cans.
(11) Most people don’t realize how strong a metal aluminum is. Four six packs can support the weight of a 4,000-lb. aluminum car.
(12)Aluminum has a phenomenally high melting point—1,220ºF, to be exact.
(57275210069)
(13) A long time ago, aluminum was a much more valuable metal than gold or silver.
ReplyDelete(14) The aluminum in one single soda can is worth about a cent. Americans threw away millions of cans last year. The American government could pay off a significant portion of its debt with a few years’ worth of aluminum cans.
(15) Four pounds of raw bauxite ore is saved for every pound of aluminum that is reclaimed in the recycling process.
(16) The aluminum Americans throw away each year is enough to provide the auto industry with all the raw material it needs to build a year’s worth of new cars.
(17)Because our landfills are so full of aluminum cans, some landfills incinerate extra aluminum. This isn’t just a huge waste; it also pours toxic metals and gases into the atmosphere.
(18) Aluminum is valuable. It’s still very much in demand, and recycled aluminum is just as useful and desirable as new. In fact, aluminum is the only recyclable material that depots can recoup their recycling costs with.
(19) Making aluminum from bauxite ore is a dirty process—and burning it is even worse. By doubling our aluminum recycling rate, we could cut a million tons of pollutants per year out of the atmosphere.
(20)Recycling aluminum isn’t just about collecting cans. You can also recycle old siding, aluminum foil, and even the gutters on your roof. Most recycling depots that take cans will also take these materials.
(21) Every part of the can is reusable—you don’t have to prepare it in any way, other than to rinse it out.
(22) In 1996, aluminum manufacturers saved enough energy by recycling aluminum instead of creating it from bauxite ore to power a city the size of Pittsburg for six years or so.
(23) Aluminum recycles in no time at all. When you send a can to a recycling depot, it’s processed, recycled, and back on the shelf again in about a month.
There’s no downside to recycling aluminum: it’s fast, it pays for itself, and it’s great for the environment. So next time you get ready to throw out that aluminum foil you wrapped your sandwich in at work or at school, think again—that aluminum could be back on the shelf in a month, save enough energy to run a big appliance like a TV for three hours or so, and pay for its own recycling costs in the process. Recycle it instead of throwing it out, and you’ll be doing the world some good.

Aluminium can be recycled over and over again without loss of properties. The high value of aluminium scrap is a key incentive and major economic impetus for recycling. Aluminium recycling benefits present and future generations by conserving energy and other natural resources. It saves up to 95% of the energy required for primary aluminium production, thereby avoiding corresponding emissions, including greenhouse gases.
ReplyDeletei. Used aluminium is valuable
• It is easily and endlessly recycled without quality loss. Aluminium makes a major and unique contribution to support product recycling into the future and to the benefit of society as a whole.
ii. Aluminium has unique recycling qualities
• The quality of aluminium is not impaired by recycling it can be repeatedly recycled.
iii. Aluminium recycling saves energy
• Remelting used aluminium saves up to 95% of the energy needed to produce the primary product.
iv. Aluminium recycling is economical
• It uses less energy and recycling is self-supported because of the high value of used aluminium.
Aluminum is often used to create alloys. Alloys are substances created by fusing two or more metals--or metal with a nonmetal--together at the atomic level. When a manufacturer needs an aluminum alloy with a specific chemical composition, secondary specification is necessary. In this method, scrap metal from a variety of sources is melted down and combined in the specified manner.
Used beverage containers (UBCs) are the largest component of processed aluminum scrap, with most UBC scrap manufactured back into aluminum cans. Die casts used by the automotive industry constitute the second largest portion of recovered aluminum. In the future, increased demand for fuel-efficient, lightweight cars is expected to make aluminum more popular in automobile manufacturing.
The largest concentration of domestic aluminum consumption is in transportation, containers and packaging, and building and construction. Combined, these three markets account for almost two-thirds of industry consumption. The next largest grouping includes electrical, consumer durables, and machinery and equipment.
Aluminium recycling benefits present and future generations by conserving energy and other natural resources. It saves up to 95% of the energy required for primary aluminium production, thereby avoiding corresponding emissions, including greenhouse gases.

Aluminium is made from a plentiful material found in the earth's crust. It occurs naturally in a mineral called bauxite. Thus if we not recycle we will destroy our world slowly.America was realized about this since 1972 which is 53 million pounds of aluminium cans were recycled.Thus, by collecting aluminium tin in campus is good way to realise our teenagers about this.
ReplyDelete1) By recycling 1 ton of aluminum saves the equivalent in energy of 2,350 gallons of gasoline. This is equivalent to the amount of electricity used by the typical home over a period of 10 years.
2) Aluminum have good protection and strength because hard to rust thats it saves our life
3) Recycling is important because many landfills closing due to lack of additional capacity
4) Recycling saves 95 percent of the energy required to produce aluminum from raw materials.
5) Conserving natural resources is important; because it takes four pounds of bauxite ore to produce one pound of aluminum, every pound of recycled aluminum saves four pounds of ore.
6) Aluminium can be recycled into a lot of different products such as tractor trailer, car bodies, chocolate wrapping
7) Aluminium have unique characteristic which is Lightweight, Strong , Resists Corrosion, Excellent Thermal Conductor, Does Not Emit Sparks, Suited to Extreme Cold
8) Because it have suited to extreme cold characteristic it useful for cryogenic applications and in the extreme cold of outer space, as well as for aircraft and for construction in high latitudes.
(57274210017)
There is many important that we can get from recycling aluminium tins.
ReplyDelete1) For each pound of aluminum recovered, we can generates about 7.5 kilowatt-hours of electricity.
2) it need about 9,000 pounds (4,086 kilograms) of bauxite (aluminum ore) and 1,020 pounds (463 kilograms) of petroleum coke (fuel) to manufacture one ton of aluminum. Using recycled aluminum to produce aluminum reduces raw material requirements by 95 percent and energy requirements by 90 percent.
3) to produce a recycle aluminium, it will produce just only 4% of CO2 rather than primary producing that produce a lot of CO2. hence, we can reduce air pollution that lead to the acid rain that making a water pollution from that acid rain. thereby, our water resources will be conserved.
4)we can reuse the existing aluminium tins to make tea light candle, ashtray and pen holder.
5) the other renewable resources is glass, tiles and paper.
6) If the landfill is become as a part of design process, all the aluminium at landfill will be used easily and no of aluminium will be left without. It also, will save the time to transfer the tin from other place to the other place.

ReplyDeleteAssalamualaikum wbt.
ReplyDeleteAs for me, recycling the aluminium has many advantages. The relation of recycling aluminium with the method of conserving the energy is just one! It is a smart way.
1. As to conserve the energy, we are also on the track to reduce the money that UniKL MITEC has spent on to pay the electrical bills. In order to do that, i suggest MITEC spend just a little amount of money - that is just to be spending on the recycle bins. Otherwise, the problem of over spend the money in terms of just for the bills is RIDICULOUS.
2. Besides, the concept of recycling water is not a new topic nowadays. We should implement the method at our campus so then all the plants shall be water using the recycle water that is from the rain. This is smartest and easiest way to educate the student. I would highlight the MITEC campus here because we supposedly implement it FIRST at our campus. If we never start it, just forget about how to conserve the country's energy & money, soon.
3. Speaking of opportunities that may have if we reuse & recycle the existing materials, i would say there is a lot of it. First, by doing it so we would reduce the budget of producing the aluminium products itself. It takes about a million just to find the source, which is if Im not mistaken produced naturally from the earth's crust. Don't u think by recycling or reuse the existing aluminium products, would save the earth and all the living creatures as well. Please bare in mind, we do share this world. We could also be a creative person by invent something from the aluminium scraps itself. Yeah, this is what we call an engineering technologist- create / invent something for the sake of future. Well i guess this is also about green engineering.
4. Renewable resources – “A substance of economic value that can be replaced or replenished in the same amount or less time as it takes to draw the supply down. Some renewable resources have essentially an endless supply, such as solar energy, wind energy and geothermal pressure, while other resources are considered renewable even though some time or effort must go into their renewal, such as wood, oxygen, leather and fish. Most precious metals are considered renewable as well; even though they are not naturally replaced, they can be recycled because they are not destroyed during their extraction and use “ . - http://www.investopedia.com/terms/r/renewable_resource.asp (reference)
As mentioned above, I would like to talk on solar energy-sounds simple but contribute a lot to our campus. Well, we do know about the cost of installing the solar energy stuff. Seriously, it is high in budget, BUT what is there if we just spend on a one time investment rather than we have to crack our head just to find the money to pay the bills monthly. We can save the electrical bills and the energy that we have to use just to produce electrics.
5. Green Engineering is the design, commercialization and use of processes and products that are technically and economically feasible while minimizing:
» Generation of pollution at the source
» Risk to human health and the environment

ALLUMINIUM TINS ARE BEING COLLECTED IS CAMPUS FOR RECYCLING.FIND INFORMATIONS ON WHAT HAPPENS TO THE ALLUMINUM TINS AFTER BEING COLLECTED
ReplyDelete1) Aluminium cans that are recycled are melted down and turned into ingots of aluminium which are used to make new cans. This is called closed loop recycling, because old cans go in and metal to make new cans comes out
2) Aluminum cans are unique: Within 60 days, a can is recycled, turned into a new can and back on store shelves. Aluminum is a sustainable metal and can be recycled over and over again.In 2007, 54 billion cans were recycled, saving the energy equivalent of 15 million barrels of crude oil – America’s entire gas consumption for one day.
3) Aluminium beverage cans have a protective polymer coating applied on the inside to prolong storage life. This polymer coating ensures that the acids and salts in beverages never actually come into contact with the metal.
4) To reducing the need for these damaging extraction processes, recycling cans also reduces consumption of energy from burning fossil fuels. According to the Can Manufacturer’s Institute, aluminum recycling each year results in energy savings big enough to meet the lighting needs of a city the size of Pittsburgh, PA, for six years. Recycling saves landfill space too: Over 1.6 billion pounds of aluminum cans are recycled annually.
5) Recycling cans also reduces the environmental impact of mining processes. According to the International Rivers Network, aluminum smelters flood vast tracts of land and displace thousands of people. In fact, recycling aluminum creates 97 percent less water pollution than producing new metal from ore.
6) The dross produced by the aluminium industry, although a waste, contains aluminium and other valuable elements (aluminium oxides), which could be recovered and reused. Conventional methods recycle less than half of all white dross and all black dross is sent to landfill. However, a new method has been developed, currently in use by Jesse Brough Metals Group (JBM International), which could recover 100% of aluminium dross
57274210035(MUHAMMAD AMIRUL RIFHAN BIN ZAHARI)
Based on my opinion, recycle is very important as waste has a huge negative impact on the natural environment. Huge amounts of energy are used when making products from raw materials. Recycling requires much less energy and therefore helps to preserve natural resources.
ReplyDelete1- The process of recycling are use HUGE amounts of power, it takes 15 kiloWatt hours (that's 15 electric fires running for 1 hour) to make just 1 kilogram of aluminium (we used over 30 million tonnes of aluminium last year - and there are 1000 kilograms in 1 tonne!) In fact it needs so much power that you only find aluminium being made in places with lots of cheap electricity - so some of the biggest aluminium plants in the world are found in Iceland and Norway where they have plenty of hydroelectricity.
2- We can recycle aluminium cans and create a wonderful fund raising opportunity for any university, any team, any organization, anywhere. For a wonderful example of how recycling aluminium cans can be used to fund wonderful causes. This program is a great way to involve teenagers, community in an activity that benefits a very worthy cause. This program also helps people get involved in volunteering and community service. it will give people a chance and they'll prove that they can easily recycle and volunteer.
3- Nowadays, manufactures are producing renewable resources such as glass, bottles, and etc. Based on my idea for the future, I suggest that we can follow the concept of Go Green a day without plastics. In the future, the seller or shop not provides bottles or tins for customer but customer must carry their own bottles or glass.
4- The end use of material, we can make souvenirs, crafts of handmade, or recycle to use again but not burying. It is because aluminium is primary among the factors that reduce plant growth on acid soils. Although it is generally harmless to plant growth in pH-neutral soils, the concentration in acid soils of toxic Al3+ cations increases and disturbs root growth and function.
5- For the conclusion, by using the concept of recycling it can also help to reduce the greenhouse effect. Gas emissions occur due to the manufacturing, use and also the disposal of products that are not biodegradable. Therefore, recycling can help reduce the need to manufacture paper, plastics, metals and glass. This would save energy needed to manufacture new products. Using recycled products would also reduce the amount of materials (which are not biodegradable) that end up in the landfills. Materials that end up in landfills tend to decompose and cause the release of methane gas. This is very harmful for the environment; therefore such landfills are the main cause of the emission of methane gas into the atmosphere.

Aluminium tins known as container packaging made largely of aluminium. Commonly used for foods and beverage but also other products such oil, chemical and liquids. Aluminium used because it less costly but offer the same resistance to corrosion in addition to greater malleability. Aluminium tins are the most common items that found within homes that readily recognize as being recycles.
ReplyDelete1. There are only 60 days for aluminium tins to complete the recycling process and using back as other aluminium items.
2. Recycling aluminum saves 92 percent of the energy needed to produce aluminum from bauxite ore.
3. The process of aluminum recycling is also beneficial for the environment as it eliminates air and water pollution to a great extent. Scrap aluminum is an important component of the aluminum industry
4. The largest sources of scrap aluminum are beverage cans which are 100 percent recyclable. Aluminum can also be recycled from items such as door and window frames and even pots and pans. Other aluminum products which are recyclable include pie plates, foil, frozen food and dinner trays
5. Aluminum can manufacturers can produce 20 times the amount of new cans from recycled cans without increasing their energy usage, pinpointing the use of recycled cans as an energy-efficient and cost-effective business practice
6. Recycling aluminum saves money, energy, and manpower because preparing aluminum products from virgin metal consumes close to 100 times the power required to recycle aluminum. If all aluminum produced is regularly recycled, the energy saved is enough to light up a medium-sized city for close to five years
7. By recycling aluminum cans, you are helping to conserve energy. To make sure that a can is aluminum, use a magnet and see that it DOES NOT stick to the can's top and sides. Rinse the cans to prevent attracting insects and crush them if you need to save space
8. Recycling aluminum cans is one method to reduce environmental pollution. In fact, manufacturers reduce their water pollution by 97% when using recycled aluminum instead of making new aluminum for their products.
9. Increased recycling can also reduce the air pollution created from landfills or dumps incinerating aluminum cans

ReplyDeletehere some point from me..
aluminum is one of the largest material that have been used by human in everyday life. processing product(aluminum) from raw material until finish product(pure aluminum) require huge amount of energy(source that can't be renew).to solve that problem, aluminum that has been used are be recycle. recycle the aluminum use less more amount of energy. its 95% more efficiency using energy to make recycle aluminum rather than make new one from raw material. furthermore aluminum is non ferrous metal that can be recycle hundred time with less of imperfection on material properties.
by recycling aluminum it capable to reduce percentage of energy used to make aluminum from raw material. from recycle aluminum, its can form to any product such as car part, kitchen part, building part and etc. so the product affordable will low but the material quality is stiil be same depends on grade on aluminum.
practically many renewable resources can be recycle in unikl mitec such as paper, glass, plastic and wood. for further renewable resources that can be implement at unikl mitec such as reuse rain as a part of their green engineering. by doing that its capable to minimize the use of water from SAJH while optimize a sources.
recycle aluminum practically can reduce the use of landfill. let says 90% of aluminum and other material that can't biodegradable are collect and recycle. so the left at landfill are rubbish that biology will rot and turn into compost. it able to optimize the use of land.
recycle is a one of the simple way in green engineering focusing to save the planet.

Based on my opinion:
ReplyDelete1. The scrap metal may go through several hands, including a recycler or scrap metal dealer. Its route, and whether it is sold domestically or abroad, depends on such business conditions as cost of transportation, supply, and demand.
2. The aluminum cans picked up by curbside collectors is included with other scrap metals once they reach a recycling facility. The aluminum cans are shredded into strips or broken into smaller chunks before being melted in a smelter.
3. The resulting ingots of metal are transported to manufacturing plants, where they are rolled back into thin sheets.
4. These sheets of aluminum can be formed back into cans or larger products like automobile parts.
5. A recycling resource published by the city of Gainesville touts aluminum as "the biggest energy saver of all, saving 64,300-kilowatt hours per ton of reclaimed material."
6. Recycling helps reduce the amount of trash that is disposed of in landfills. Recycling, rather than throwing things away, is also better for the environment. Currently it is believed that the amount of carbon dioxide in the earth’s atmosphere is causing global warming which can have devastating long term effects.
7. Recycling is one of many ways that people can cut down the amount of carbon dioxide that is released into our atmosphere.
8. Purchasing recycled paper is also better for the environment because it takes less energy to produce recycled paper and saves some trees along the way.
9. Aluminum can be recycled into a lot of different products such as tractor trailer and car bodies, however, aluminum cans usually become new aluminum cans.

After aluminium being collect there will be several stage to recycle:
ReplyDeleteStage 1: Collection
Aluminium cans are collected for recycling in a number of ways:
can banks - located at supermarkets and council recycling sites. These are emptied by waste management companies or your local council
kerbside recycling schemes - operated by your local council to make recycling at home as convenient as possible.
Cash for cans centres - where you can exchange empty aluminium cans for cash
Once collected the cans are delivered to one of Alcan's regional aggregation centres. Here the cans are checked to ensure they don't contain any steel, plastic, paper, dirt or excess liquid as these can disrupt the recycling process. They are then baled and transported to the Used Beverage Can Recycling Plant.
Stage 2: Recycling
The recycling process has four stages.
Shredding: Mechanical hammers shred the flattened cans into small pieces, about the size of a 50p.
Decoating: Decoration is removed by blowing hot air (500 degrees celsius) through the shreds.
Melting: The shreds are melted in a furnace heated to 750 degrees celsius.
Casting: The molten metal flows into moulds and is cooled by jets of water. As it cools and the metal hardens and an 'ingot' is formed.
Each ingot weighs 27 tonnes. It is 15 metres long and contains enough metal to make 1.5 million drink cans.
The ingot is now transported from Warrington to the rolling mill.
Stage 3: Rolling
The ingots are pre-heated to 600 degrees celsius and undergo their first rolling. They are then 'cold rolled' to the exact specification and thickness required by the can maker.
Stage 4: Can Making
The aluminium sheet is lubricated and fed through a cupping press. This cuts, or blanks, thousands of shallow cups. The sides of the cups are raised to form the can shape by being rammed through a series of rings. The can is trimmed and washed ready for decorating.
The inside and outside of the can is treated with a lacquer. This forms the base coat for the external decoration and prevents the contents reacting with the metal inside.
After the decoration has been applied the cans are dried in an oven and then passed through a necker/flanger to prepare them to take the can end.
Stage 5: Filling
Cans are cleaned using high pressure air and water. Then the air is extracted and at the same the can is filled with carbon dioxide gas (CO2). The liquid contents are then added and the can ends are attached and mechanically sealed.
Around 2000 cans are filled by this process every minute.
The cans are then packed ready for despatch to the distributor or retailer.
Stage 6: Selling
The final stage of the loop is when the cans are delivered to the retailer, ready for you to buy -

Sustainable design is a kind of design meant to yield products that are made only of renewable resources. Furthermore, products made though sustainable design are intended not to seriously impact the environment either when they are being created or when they are being used. These products are also often designed to allow the users to feel more connected or to relate more closely to the natural environment. Our main discussion now it’s about sustainable of tins aluminums that can be recycled for the world.
ReplyDelete1) There are many type of method that cans us use for conserving energy and water resources. Now our discussion about tins aluminums which is it takes much less energy to recycle an aluminum soft drink can than it does to make a new one. Making energy uses up resources like oil and coal. So just by recycling the aluminum cans you use, you can be an instant conservationist.
2) There are a lot of opportunity that can we get from the recycling the tin aluminums cans such as Multiple Recycling which is unlike some other items that are recycled, aluminum is an ultimate recyclable material. It can be recycled endlessly. Besides that, Waste Prevention can be used in the recycled like aluminum cans are thrown away every day. If not recycled, the waste accumulated from the discarded cans in the United States alone would be equivalent to the amount of aluminum used in a whole fleet of commercial airplanes. Hence, it’s also give opportunity for Ease of Recycling such as aluminum cans can be taken to recycling centers or put on the curb for local recycling pick-up programs in some areas. Other than making sure they are reasonably free of debris, aluminum cans take no preparation to set out or bring in for recycling.
3) The renewable resources are not limited. For instance sunlight, wind, tidal energy and wave energy. These are examples of natural resources where we cannot imagine a time when we will not have an abundance of such resources. But there are also other renewable resources such as trees, plants, crops, and in fact all growing matter on earth. These are renewable because they can grow again and again. Our only limitation in making them grow would be availability of water and land and in extreme conditions, sunlight. For example, we can use solar power to generate the electrical power or to generate the mechanical machine. This system may save the world form the wasting material and pollution.
4) Recycling cans is good for the environment because it decreases the amount of garbage in landfills and decreases the amount of energy used to mine, process and transport the metals used to make cans. Conserving water helps reduce the amount of energy used to purify and transport water, and helps make more water available and less expensive for businesses that need it to operate.
Conclusion
By development the sustainable design of the product such as applying green engineering into the world, its may give the world more safety and secure from the pollution or some wasting problem. From that, consumer should participate to make sure all the problem can be solved stage by stage form the beginning until the end of the problem solve.
