GO GREEN WITH SOLAR PANEL!

Nowadays, pollution is getting worse and worse. It can be one of the biggest killers, affecting more than 100 million worldwide. You don’t want to die fast, right? Let’s save the world and be green with solar panel!

Pollution is one of the biggest issues that every nation faces right now. Every nation only competes to be the number one in economic development and sometimes ignore about environmental condition. The fact is every nation should attain sustainable development, which is balance between economy, environment, and social community.

Energy which is very important for economic development of nations is getting fewer. Every nation exploits energy in order to achieve rapid economic growth. Total energy needs in the world currently reach 10 Terra Watt and this number will increase until 30 Terra Watt in 2030. The increasing number of total energy needs collide with the sustainable concept that human needs to pay attention to. Solar panel as alternative energy source can solve this problem.

Solar panel is a panel designed to absorb the sun’s rays as a source of energy for generating electricity or heating. Solar energy is actually the most promising energy sources because it is unlimited and sustainable. The sun is expected to address future energy needs problem because most of energy sources are limited and not environmental friendly.

Solar panel work using p-n junction principle, which is the junction between p-type and n-type semiconductor. This semiconductor consists of bonds in which atoms are electrons as the basic constituent. N-type semiconductors have an excess of electrons (negative charge) while the p-type semiconductor has excess holes (positive charge) in the structure of the atom. The role of p-n junction is to form an electric field so that electrons (and holes) can be extracted by contact material to produce electricity. When the p-type semiconductor and n-type contacted, then the excess electrons will move from the n-type semiconductor to the p-type to form a positive pole on the n-type semiconductor, and conversely the negative pole to the p-type semiconductor. As a result of the flow of electrons and holes is to formed electric field which when the sun light on the composition of the p-n junction will push electrons move from the semiconductor toward the contact negative, which in turn is used as electricity, and vice versa hole moves toward the positive contact waited electrons come.

Solar panel consist of substrate/metal backing, semiconductor materiel, contacts metal/contact grid, antireflective coating, and encapsulation/cover glass. Substrate/metal backing is material that sustains all components of solar cells and it must have a good electrical conductivity. It can be made by metal material such as aluminum.

There’s a lots of advantage using solar panel, especially solar panel doesn’t cause any pollution and it’s free energy! You can be go green, save the world, and less money! So, you still doubt to save the world with solar panel? We, Shanghai Metal Corporation can provide you good quality of aluminum that can support your solar panel!

Iron-air batteries: a cheap and eco-friendly solution for energy storage

After more than 40 after preparing the first prototype of a cheap , rechargeable, high energy density iron-air battery, researchers at the University of Southern California are now finishing the job of the patent-pending design of the battery.

The technical characteristics of the batteries look particularly well-suited to the kind of large-scale energy storage that could accelerate the adoption of renewable energy sources.

Back in the 70’s, researchers were already working on environmentally friendly rechargeable lithium-ion batteries and only recent advances in materials technology have made this technology into one of the most common, high-performing solutions for today’s portable electronics.

Iron compared to other materials has a few advantages: it’s durable, it has a great capacity to pack energy (per unit of mass), it’s recyclable but most importantly it’s cheap with costs around US$1/kg (2.2 lb).

Iron-air batteries were first expected to be used for electric vehicles and military applications after the 1973 oil crisis. However, research stopped abruptly only years later, when scientists realized that iron-air batteries presented a serious limitation: whenever the battery was being charged, a wasteful process of hydrolysis drained away about half of the battery’s energy.

With today’s technology and advanced research, University of Southern California found a solution to this problem. They learned that adding a small amount of bismuth sulfide into the battery shut down the harmful reaction and reduced the waste of energy more than tenfold, from 50 down to just 4% .

The other good characteristic cost-effective design of its iron electrode. The researchers combined iron powder with a polyethylene binder, heating the mix to obtain a “pressed-plate” electrode that is simple to make and has high specific energy.

The iron-air battery is exhibiting very promising durability, with a target life of 5,000 charge-discharge cycles. Even more importantly, the batteries seem to retain good performance when they are being drained quickly: at a two-hour rate of discharge, the batteries are showing a twenty-fold increase in capacity compared to commercially available electrodes.

Use of Solar mirrors to Melt Metal, an efficient metal processing Method

As manufacturing plants are being under pressure to reduce their energy spending, many countries and companies are trying to make progress in innovating. some researchers from Germany and South Africa have proposed a technique to reduce the emission in metal processing factories. and will use South Africa’s large aluminium processing industry as a test bed.

In addition to powering electricity-generating turbines , the large mirrors can also melt metals thanks to their ability to concentrate solar rays. The process helps reducing carbon footprint of the metal processing industry.

The preliminary concept is going to be tested first in Germany at the Aerospace Centre’s (DLR) by the Institute of Solar Research in Julich before launching it in South Africa.

According to these researchers, solar mirrors would focus sun rays reaching 700°C to a rotary solar kiln which will be able to melt aluminum ore but also recycled aluminum objects. In addition the research team will develop a logistics plan to transport the molten aluminium from the central solar melting plant to the production facilities where liquid metal will be processed.

“The aim of the project is to develop an energy and cost effective method that can be implemented across a variety of system sizes, depending on the requirements,” said Martina Neises-von Puttkamer, project manager at DLR.

South Africa is a particularly interesting place to start the project because the country’s metal processing facilities rely mostly on electric energy coming from coal-fired power plants which brought them to become the 15th largest greenhouse gas emitter in the world. Also Metal processing is the country’s largest industry.

Aluminum, Metal of choice for sustainable cans

the Aluminum Association and Can Manufacturers Institute (CMI) new report states that aluminum cans are the most recycled beverage containers in the market, they have the highest recycling rate. A can usually contains 70% of recycled content, which is 3 times more than plastic or glass containers all this while being around 300 percent more valuable than other materials. A can is generally turned into a new can and back on store shelves within 60 days.
In addition aluminum cans have become lighter by 38 percent since 1972 in the United States, with a weight of 12.99 grams approximately. Aluminum cans are more than 15 times lighter than standard 12 oz. glass bottles, which makes it easier to transport bigger quantities of beverage and optimizing their transportation costs.

An Aluminum can goes through several steps during its life span from one recycling process to a new one

Stage 1 : Can Shredding

In this step cans are shredded into pieces the size of a walnut. The shreds are then passed through a double magnetic drum separator to remove any steel that may have been mixed into the bale.

Stage 2 : De-coating

Any paint or other chemical coating on the aluminum is removed by blowing hot air (around 550°C) through the shreds on a slowly moving insulated conveyor. The exhaust gases from this process are first passed through an afterburner and then used to heat incoming process air via a heat exchanger, minimizing the energy requirements of the system

Stage 3 : Melting

After the de-coated process, the aluminum shreds are put into a melting furnace containing submerged stirrers that create a vortex in the pool of molten aluminum and drag the shreds quickly down into the melt.

Stage 4 : Aluminum Casting

The molten metal is transferred into a furnace to remove impurities and start the casting process then Ingots are cast from the remaining pure metal.

Once in the mold, cool water is sprayed around and through the base of the mold. The aluminum ingot ten solidifies for the next three hours. The finished 18-ton ingots, each containing approximately 1.5 million used cans, are shipped to a mill for rolling into the sheet from which aluminum can makers subsequently produce new cans and the whole process begins again.

China, Second Biggest Producer of Copper In The World (List of Top 10 producers)

copper bloomberg — copper tubes source: bloomberg.com

Most copper is mined/extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain between 0.4 to 1.0% of copper. This is the case in some mines in Chile and the United states .

According to the British Geological Survey The amount of copper in use is increasing and the quantity available is barely sufficient to allow all countries to reach developed world levels of usage.
It was reported by the US Geological Survey (USGS), the global production of metal increased by 400 million tons between 2013 and 2014 reaching 18.700 million tons, although the demand for copper decreased compared to the previous year.

1. Chile (Mine Production: 5.800 million tons)

Chile’s copper production has been increasing for the last decade although technical and regulatory issues could slow down the trend. between 2013 and 2014 the production increased from 5.780 to 5,800 tons.

2. China (Mine production : 1.620 million tons)

China is the largest refined copper producer, but it lacks copper mineral deposits. It has to import unprocessed copper ores and copper scrap.
China increased its copper production in 2014, putting out 1,620 million tons of the metal compared to 1,600 million tons in 2013. Reuters reports that notes that the country’s production increased during the second half of the year, due to the re-lauching of a 100,000-tonne-a-year smelter Liaoning province (North east of China) after 5 years of inactivity.

3. Peru (Mine production: 1,300,000 tons)

between 2012 and 2013 peru’s prodcution didn’t change much. In 2013 the country produced 1.300.000 tons. But it is expected that the mine production could rise by as much as 10 percent in 2014, and Peru’s energy and mines minister, Jorge Merino, has projected a 17-percent increase in copper production alone thanks to several new projects and also the the expected increase of foreign investments in the mining industry.

4. United States (Mine production: 1,220,000 tons)

5. Australia (Mine production: 990,000 tons)

6. Russia (Mine production: 930,000 tons)

7. The Democratic Republic of the Congo (Mine production: 900,000 tons )

8. Zambia (Mine production: 830,000 tons)

9. Canada (Mine production: 630,000 tons)

10. Mexico (Mine production: 480,000 tons)

The attraction for copper nowadays

Du cuivre — Photopqr – Le Parisien – Daboval Adeline

It’s a good and an unfortunate assessment at the same time that we are able to do each year.

In fact, the attraction for copper have increased the business of this type of metal for manufacturers but unluckily for our customers, the steal of copper is a real problem in Europe, until the point that it became a scourge for European countries.

Italy is one of the most important victims of these thefts in Europe. According to the newspaper Le Figaro, between 2010 and 2011 the number of thefts has known an increase of 300%, from 408 to 1226 cases. These thefts represent almost 631 tons of copper which have been stealed during this period. And the numbers are not decreasing. In Belgium the observation is even worst, from 290 cases of thefts in 2009, the Infrabel Group reported 1 362 cases in 2012. The value of the copper robbed was approximately of 8 millions of Euros which is significant for the Infrabel Group according to the Fedra newspaper.

In the United Kingdom, France and other European countries, the observations are the same. In the UK, the police have made of this problem their second preoccupation after terrorism, which is quite representative of the scope of the thefts.

The railways are not the only targets of the organized gangs. Electrical communications, communication networks, construction sites or private houses, are also concerned about this problem. The fact of stealing is not the only problem for these companies, there is many consequences for the companies’ victims of the piracies.

These thefts are creating delays for the companies, and for the railways companies, the cost is huge. In the United Kingdom, the thefts and delays of the trains have created 770 million pounds or 900 million Euros in 2011 of loss. In Belgium these thefts have resulted of 66 440 minutes of delay for the SNBC Group.

The cause of the increase in the attraction for copper is that the copper is becoming rare and as a consequence the price is sharply rising. In 2011, the price of a tone of copper represented 8 000 Euros, five times more than ten years before. Sold in the black market the copper means a lot of money for the organized gangs.

The copper is not the only metal attracting these groups, zinc, steel and nickel are also famous metals experiencing a resurgence of thefts.

ALUMINIUM – THE BATTERY OF THE FUTURE

Why do we like so much aluminium at Shanghai Metal Corporation? This is a very easy question. Because aluminium is a very versatile material that can be employed for a wide range of purpose. For instance, according to some specialized websites in the near future aluminum may be used in the production of various electronic devices batteries. The researchers of the University of California at Stanford have announced the development of aluminum-based batteries promising better performance and a lower impact on the environment compared to current models made of lithium.

What is more special about the aluminium batteries is that, not only their life would be significantly higher than conventional batteries (7,500 versus 1,000 cycles), but especially we should be able to fully recharge them in just a minute. Moreover, the aluminium batteries could be applied to a high number of devices such as smartphones, electric cars and laptops.

Since aluminum is very less expensive than lithium, a further advantageous feature of the aluminium battery would be its lower cost of production. Furthermore, aluminum guarantees the total absence of any risk of fire. The environmental benefits are obvious. A smartphone battery that takes only one minute to charge results in a considerable decrease in energy waste.

Bottles’ battle – the Winner Is…

There have always been discussions about what kind of water bottle is the best. Plastic? Stainless steel? Aluminum? Or glass bottle? Due to protect our environment, everybody wants to purchase a reusable water bottle but sometimes it is hard to make a right decision and the amount of different products makes it even harder. Here is some information to make you choose easier between aluminum and stainless steel bottles.

Stainless steel water bottles

Stainless steel was the standard for buildings and also a sign for the economic growth in the late 1800’s to early 1900’s. Nowadays it found its way to reusable bottles. Stainless steel bottles are usually crafted from culinary-grade stainless steel and come in various sizes and colors. If you are concerned about manufacturing techniques or toxins, stainless steel bottles are a good alternative to plastic bottles. As stainless steel is non-reactive, bottles do not leach, they don’t have to be lined and the don’t affect the taste of drink. Stainless steel bottles are probably not really suitable in hot climates because the metal heats up more quickly. On the other hand you can be sure that it will last you a lifetime and can withstand daily wear.

PROS : CONS :

– dishwasher safe – can dent if dropped

– durable – heats up in hot climates

– 100% recyclable – not microwaveable

– high-quality design – energy intensive manufacturing

– no plastic toxins – possible metallic taste

Aluminum water bottles

Aluminum has a variety of applications, but aluminum is probably most used for packaging of beer, soda, tea and other drinks. Aluminum bottles and stainless steel bottles often look and feel similar. But aluminum bottles have are dramatically different. As aluminum reacts with certain liquids, aluminum bottles are usually lined with an enamel or epoxy layer. The most popular aluminum bottles have narrow necks which makes them difficult to clean, dry and load it with ice. Those aluminum bottles with certain types of lining are not recyclable.

PROS : CONS :

– trendy – not dishwasher safe

– lighter than stainless steel – can dent more easily

– less expensive – difficult to clean

– keeps beverages cold – chemical leaching possibility
