Recycling of aluminum can contribute much to the environmental aspect in terms of sustainability. If we look at the present condition of climate and how wastes are managed, understanding the process on how aluminum is recycled can empower persons and business people into being part of the practice. In the present blog, we will get more and more information in depth with respect to aluminum recycling processes and its benefits along with some very common questions asked. Let’s get started!
What is aluminum recycling?
Aluminum recycling gathers used aluminum materials and puts it into new aluminum products. It saves natural resources, saves energy, and prevents the emission of other greenhouse gasses.
The Aluminum Recycling Process
The aluminum recycling process can be broken down into several key stages:
1. Collection
The first step is scrap collection. Aluminum can be collected as scrap from numerous sources.
- Households: Make use of cans, foil, and other aluminum products.
- Businesses: Aluminum scrap generated from manufacturing processes and packaging.
- Recycling Centers: Collections of plants that gather and process recyclables.
2. Sorting
After collection, aluminum is sorted from other materials. This may be hand sorting or with automated systems that use magnets and air classifiers, separating aluminum from other metals, plastics, and contaminants.
3. Shredding
Aluminum is shredded after sorting into small pieces. This easily melts and processes the aluminum. The shredding also helps in volume reduction of the material, making transportation and processing easier.
4. Melting
The shredded aluminum is then melted in large furnaces. This process requires significantly less energy as compared to the manufacture of new aluminum from bauxite ore. Recycling aluminum saves between 95% and 95% of the energy needed for the creation of new aluminum, on average.
5. Purification
Once it is melted, there may still be impurities in the aluminum. There are various processes of purifying the product, which one is fluxing. The process should yield a final product that is high quality and can be used again as raw material in manufacturing.
6. Casting
The purified molten aluminum is then cast into large blocks called ingots or billets, which may be transported to manufacturing facilities for more product development.
7. Manufacturing
The last process is the production of new products from the aluminum ingots sourced above. These may include cans, foils, car parts, or building materials, among many others. Therefore, a closed-loop system improves on the minimization of virgin aluminum while preserving raw natural resources.
Benefits of Aluminum Recycling
1. Preservation of the Environment
By recycling aluminum, there will be a lesser dependency on bauxite mining, which is destructive to the environment. Fewer habitats will be destroyed and soil erosion, as well as water pollution, will reduce.
2. Conservation of Energy
As discussed earlier, recycling aluminum conserves the equivalent of 95% of the energy that will be required in the production of new aluminum from ore. The energy will conserve fossil fuel use, which in turn conserves greenhouse gas release.
3. Economics
Aluminum recycling industries, therefore, create employment and increase economic activity. A number of jobs are created in collection, sorting, and processing activities of recycling facilities, which are used to facilitate local economic activities.
4. Resource Conservation
Aluminum is a scarce material. Recycling will save some of this precious material for our progenies and, in doing so, will also save the extraction of new resources.
5. Community Participation
Recycling of aluminum within communities enhances environmental awareness and responsible consumption behaviors. It makes people and business ventures undertake more responsible behavior.
Where do you source Aluminum scrap?
Aluminum is one of the most prevalent metals used in our daily lives. Apart from household items, this metal is commonly used to make drink cans, bicycles, and for building car engines. Few other areas where they are used have been mentioned below:
Drink Cans
Pots and pans
Window frames
Doors
Car parts
Ladders
Mag wheels
Aluminum scrap wire
Scooter engine
Cooker and many more
The mining process of aluminum is very costly as well as it requires much energy, which causes hazardous health problems in wildlife and destroys the ecosystem. However, other studies also state that the usage of aluminum is tolerated by the flora and fauna. Though the demand of the Aluminum scrap is increasing day by day, global warming and other such issues have become the major challenges to access its huge mining.
Other products containing aluminum are antiperspirants and antacids. Its consumption, which is not associated with any side effect, causes health issues in people who are allergic to
aluminum, such as vomiting, digestive problems, contact dermatitis, and other health problems. Unlike other heavy metals, aluminum does not possess toxins.
The aluminum scrap price depends on lots of things; specifically it is calculated on the basis of the metal’s pureness. If you want to sell the pure aluminum then it may cost much more than that of combined aluminum with an iron.
Since this metal is sold everywhere in the world, the price of aluminum scrap varies with the exchange rates of the country and demand for the metal. Similarly, the scrap wire price, scrap copper prices, and scrap cable prices change according to their respective demands and availability.
FAQs About Aluminum Recycling
Q1: Are all aluminum products recyclable?
A1: Yes, all forms of aluminum products are recyclable, from cans, foil, and bits of an automobile to other items. However, some contaminated products carrying food waste or mixed materials cannot be taken for recycling.
Q2: Is the aluminum product retrievable for a countable number of times?
A2: Aluminum can be recycled an infinite number of times without loss of quality. The attribute makes it one of the most recyclable materials known.
Q3: What happens to the collected and sorted aluminum?
A3: The alloying stock, here taken as a nearly pure form of aluminum, is melted down and cast into ingots or billets, which are further rolled and manufactured into different products.
Q4: Is aluminum recycling profitable?
A4: Yes, aluminum recycling can be profitable because it is in demand and due to such a large amount of energy saved in recycling that process is so viable.
Q5:Where is aluminum recycled in my neighborhood?
Q5: You can check at your local recycling centers or waste management services to see if such a program is offered in your locality. Most municipalities offer curbside recycling of aluminum cans.
