The school-Pianciani Manzoni since 2 February is actively collecting aluminum. There are many classes that have joined the initiative promoted by the VUS of Spoleto and also eco-friendly us, as we are concerned with saving the planet, we could not feel themselves compelled to work for this collection.
Some questions arise spontaneously talking about this material and we have tried to give answers that might be useful now, and especially for the future, your future sustainable !
- Recycled aluminum is present in Italy? -
- You just think that all Italian coffee makers are made of recycled aluminum!
- Aluminum is recyclable?
- Yes, 100% and infinity
- It really saves by using recycled aluminum?
- Yes For a pound of aluminum extraction process requires 15mW, but to get the same amount from aluminum are recycled only 0.2mw, a savings of 20 times
- What is the benefit we get, in addition to savings, from recycled aluminum?
- recycled from aluminum you can get many things. Here is a small list:
• With 37 cans can make a coffee.
• All coffee produced in Italy (7,000,000 units) are made of recycled aluminum. • 3 cans will make a pair of glasses.
• With 130 cans building a scooter.
• With 640 cans can make a car rim.
cans • With 360 you can build a racing bicycle.
cans • With 800 you can build a bike complete with accessories.
• With 1 kg of recycled aluminum saves 45,100 calories, which is the energy of 210 bulbs lit for 1 hour. Now some news
aluminum.
has the symbol Al Aluminium is extracted mainly from bauxite ore are significant and its resistance to ' oxidation , its softness, and its lightness. Aluminium is used in many industries to manufacture millions of different products and it is very important for the world economy. Aluminum is a soft, lightweight but strong, with a silver-gray appearance due to the thin layer of oxidation that forms quickly when exposed to air and to prevent corrosion. Aluminium has a specific gravity of about one third of ' steel . From the industrial point of view this lightweight metal is produced from bauxite, rock, red-brown or yellow. It is completely recyclable, and you may use al'infinito, just think that in Italy almost all the coffee pots are made from recycled aluminum. The recovery of this metal from waste (through recycling ) has become an important part of the aluminum industry. Recycling is not new, is a common practice since the early twentieth century . It was still a low-profile until the early '60s when Recycling cans put this practice in the public eye. The sources for the recycling of aluminum frames and include cars, appliances, containers and other products. Recycling is very convenient: to produce a pound of aluminum ready for use from scrap costs less than 1 kWh, compared to about 13-14 from the mineral production. The aluminum used to produce the new object will not end up in a landfill and this simplifies the problem of where to put our garbage. So when you put your cans in a container for recycling, you know that will be used to produce a new object. But how? Can be used as a can be transformed into a sealed container or in a part for a car or a plane?
The aluminum recycling plant
When the can was taken from the point of collection, is crushed and taken to the recycling facility. The plant has four stages:
1) The aluminum used, which is stained, painted and sometimes coated is placed on a conveyor belt and cut into small pieces. Along the same tape, then passes through the large magnets. This removes the steel and other metals that were set with aluminum. It 's a necessary procedure because other metals are recycled in different ways.
2) The aluminum is then loaded into a furnace designed to remove dirt and paint. The oven is heated until the paint and other coatings do not dissolve, separating from aluminum, and are then sucked away by powerful fans.
3) While still hot, the pieces of aluminum were placed in a furnace, which melts them completely and shuffle them to ensure a good quality for reuse.
4) After the merger, aluminum is poured into large molds and is ready to be sold.
short, waste aluminum is a waste, do not understand why people complain of too much garbage, then when something is not to be thrown together with others to reduce their volume do not we? What do you need the separate collection?
