Carbon Recycling Intl # 39; News methanol plant renewable energy
Aluminum is the most abundant metal in the earth's crust, is unsurprisingly one of the most recycled materials today, after the steel and paper It is also the only packaging material that completely covers the cost its own collection and processing in aluminum recovery recycling centers for recycling is not only economically viable, but efficient and environmentally friendly energy.
Due to the limited availability of these metals, the free flow of non-ferrous waste from country to country depending on the industrial demand and consumption is crucial BIR has always championed the free movement of secondary raw materials to avoid shortages in certain geographic areas and surpluses in other import barriers could limit the supply to the manufacturing industry in some countries.
Many metal recycling rates have increased in recent years more recent MB Steve Karpel summary based on the reports of the UNEP Resource Group.
The metal recycling industry has an efficient structure with many small businesses buying scrap material and food to this very effective biggest international companies.
recycling non-ferrous metals involves some or all of the following steps.
The power recovered copper wire in a belt conveyor for recycling.
Sorting order to be recycled in an appropriate manner, different types of non-ferrous metals should be separated from each other, and other recyclables such as paper and plastic.
The setting nonferrous materials bales are compacted into large blocks for ease of handling and transportation.
Hydraulic Shear able to exert enormous pressure is used to cut metal in reasonable proportions.
Shredders separation media incorporating magnetic rotating drums for separating non-ferrous metal from ferrous further separation is performed using electric current, the flow of high pressure air and liquid floating systems Further processing may be necessary .
Melt the recovered materials are melted in a furnace, poured into the rollers and formed into ingots These ingots are either used in the foundry industry or they can be made into flat sheets and other wrought products such as tubes, which are then used to manufacture new products.
All metals can be recycled with little or no loss of their original physical properties These are versatile materials that possible applications for each metal and combinations are endless.
Aluminum has a high potential for recycling and is often reused for the same purpose for which it was manufactured Its strength, flexibility and lightness make it ideal for.
construction window frames buildings, building structures, roofs, etc.
The transport planes, trains, boats, cars and trucks It is also used in small vehicles such as bicycles, motorcycles and other mobility devices such as wheelchairs.
Aluminum packaging is used primarily in the form of cans and foil.
Electricity Since 1945, aluminum has replaced copper in high voltage transmission lines.
After silver, copper has the highest electrical conductivity of all the elements is also very good conductor of heat and is easily alloyed with other metals such as lead, tin and zinc for foundry applications to produce among other products, products for the transmission of water such as valves.
Other common applications include secondary copper.
Applications electric wires, circuits, switches and solenoids.
plumbing fittings and also in refrigeration, air conditioning and water supply systems.
Household Cookware, door handles, and cutlery.
The most recycled lead is used in batteries, but many other applications for this metal.
Lead Car batteries is still widely used in the plates that function as electrodes.
Although less common today coloration, it is used in ceramic and glass windows.
Protection against radiation lead provides protection against X-rays
Zinc is present in the life of every day in the form of coins, however, also has other important uses.
Galvanizing zinc is generally applied as a coating to protect iron and steel corrosion in a process known as galvanizing.
Batteries as an anode component material in batteries.
Apart from precious metals, tin is one of the most expensive non-ferrous metals Therefore, recycling of secondary materials is very important Its applications are varied.
Cans by covering the steel sheet with a thin layer of a tin obtained tin, the raw material to make boxes.
tin production of the vehicle increases the resistance of the engine block, piston rings and clutch discs.
Springs of all kinds become more difficult by adding tin.
Glass tin oxide coatings on glass surfaces to make them more resistant.
Nearly 40 is satisfied the demand for copper in the world using recycled materials.
At present, about 30 of the world zinc production comes from secondary zinc.
Over 80 zinc available for recycling is ultimately recycled.
Out of an estimated total of 700 million tonnes of aluminum produced since commercial production began in the 1880s, about 75 of it is still used as secondary raw material today.
A ton of recycled aluminum saves up to 8 tons of bauxite, 14,000 kWh of energy, 40 barrels of 6300 liters of oil, 238 million BTUs of energy s and 7 6 cubic meters of landfill.
Saving energy by recycling one ton of aluminum is more than enough to power an American household for a year the average American household consumes about 10,000 kWh year.
Recycling aluminum 95 uses less energy than the production of aluminum using raw materials.
Recycling one aluminum can saves enough energy to power a 100 watt bulb for nearly four hours.
An aluminum used is recycled and can on the grocery shelf in as little as 60 days.
For each single box made from virgin ore, the same amount of energy used 20 will produce recycled cans.
The aluminum beverage can is recycled containing more people - more than 63 of all cans are recycled worldwide.
copper recycling value is so high that the superior quality scrap contains at least 95 of the value of the primary metal from the newly extracted ore.
copper recycling saves up to 85 of the energy used in the primary production.
To extract the copper from copper ore, the energy required is about 95 million Btu tons of copper recycling uses much less energy, approximately 10 million tons Btu.
Using copper scrap, we reduce CO2 emissions 65.
The car contains an average of up to 10 kg of zinc in galvanized body panels when they are discarded, these panels can be easily transformed into new identical quality parts.
The total zinc recovery in non-ferrous metals industrial quantities at 2 9 million tons, of which 1 to 5 million new are waste residues or treatment and 4 million are under scrap.
Production of secondary zinc 76 uses less energy than primary.
Nearly 70 of zinc from the end of life product is old recycled zinc debris consists primarily of die castings, brass objects, end of life vehicles, appliances, old air conditioning ducts, obsolete road barriers and street lighting.
50 product lead and used each year around the world has been used before in other products.
Today, about 80 Lead is used in acid batteries, all of which is recoverable and recyclable some countries have a recycling rate of 100 and most are able to the same result.
The use of secondary lead instead of ore reduces CO2 emissions 99.
Globat production quantities of tin to 350,000 tonnes of which 50,000 tonnes are produced from waste and other secondary sources Primary tin production requires more energy than 99 secondary production.
