Metal Recycling Process: A Step-by-Step Guide to Recycle Scrap


Metal recycling deals with the well-ordered collection of the several metal items after completion of their desired life span and separating them according to their type, quality and various other factors.

Metal recycling is processed in following “9 METHODS OF  RECYCLING CYCLE


Recycling cycle takes place in following 9 steps :

  • Collection
  • Rectifying
  • Condensation
  • Fragmentation
  • Melting
  • Sanctification
  • Solidification
  • Fabrication
  • Transportation


Firstly metal is collected in a proper separate container designed for metal collection only keeping in mind that other recyclable materials do not merge into it.

This is done by any particular firm dedicated for metal recycling or common people as per their environmental concern.

Sometimes people also make money for giving recyclable materials to the collectors. All the metal is then kept in scrap yards.

Now this bulk of metal collected is sorted accordingly to its type.This is really an important section of recycling since it decides different operations to be performed on different metal.

Also Rectifications subjected to the metal aims at yielding good quality materials.

Condensation refers to make the metal compact using compression machines so that its volume get decreased and its storage become easy.

Following the compaction process and reaching the smelting facilities, these metals are checked for radiation and sent into shredding machines to be fragmented into small pieces.

Hence Fragmentation results in activation of the surface area of metal.

Now this shredded metal is brought for melting in furnace. Different furnaces are used for different metal processing.

Melted material from recycling cycle is then sent for the purification process.

This can be done by various measures i.e., electrolysis, using strong magnets and various other techniques depending upon the type of recyclable materials.


This cleaned up metal in molten state is poured into molds to form ingots.

This may weigh a lot. At this point one can add up some chemicals as per maintenance of desired properties in metal.

Now this ingot of metal is allowed to solidify by transferring it to cooling chambers for giving them desired shapes.

8.Manufacture or Fabrication

Different brand new products are manufactured out of the solidified ingots obtained from above process done on recyclable materials.


These ready products obtained from metal recycling are transported for retailing or different purposes.

Finally these are sent to different industries for further modification or enhancement.

Almost all the metals exhibit 100% recyclable properties. The most recyclable materials (metals) found are mentioned below with their properties and uses.


metal recycling


AluminumIt is the third most common element on earth surface. Thus easily available to us. It is silvery in color and light in weight.· Used for making cans for beverages
Cast IronIt is a form of iron with some amount of carbon and steel present in it.·  Used to make kitchen instruments.
CopperIt is tarnished green or red colored metal. It is quite expensive but easy to reuse and recycle.·  Used for pennies

·  Commonly used for wires and pipes

· Cook wares are also made up of it

SteelIt is an alloy of carbon in silver color.Therefore it does not lose any valuable properties after being recycled.·  For packaging canned foods

·  For Rebar construction

Brass and BronzeThese are alloy of copper with some amount of zinc and tin present in it.·  Manufacturing gold and green ornaments


There are some metals which we cannot put in our recycle containers.

They do not participate in recycling cycle because they exhibit some properties which do not allow recycling them.

Examples include Mercury or the objects containing mercury, some radioactive metals such as uranium, plutonium and also some lead containing products.


When it comes to discuss advantages of metal recycling and recycling cycle in context of environmental concerns then there are several of them.

After discussing following pros you will be appreciating this idea a lot.


metal recycling

Metal production from recyclable materials involves emission of lots of poisonous gases because metal are not available in their purest form in nature.

But if we head up towards metal recycling it would definitely ensures less poisonous emission and then a considerable amount of air pollution is reduced.

If we follow this we can cut down the green house gases production by 500 million tons. And we will also contribute in giving a healthy life to people living in this environment.


We can definitely lessen the natural resource demand by recycling metal from recycling materials.

It takes a far less energy to process recyclable metals as compared to mining ores, purifying and then shaping them.

In this way, we can approximately save 92% of our energy regarding aluminum, 90% from copper and 56% from wasting in steel creation.


The bigger picture behind metal recycling is job creation. We do struggle for job creation but recycling has potential to help us out.

Recycling can create 6 times more employment than sending up the scrap for land filling. For a given quantity of avail, metal incineration would pay for single job but recycling could pay for 35 times more employment.

From some published news it is found that recycling industries are cooking up more than 236$ billion per year and recruit millions of worker annually.


The way every coin has two sides likewise metal recycling too has some cons. Mentioned below is the recyclable material disadvantages.

In metal recycling sites you have to face all the unhygienic, unsafe and unsightly conditions.

Waste piling creates big debris as well as attracting grounds for infectious diseases. It creates a severe health risk for people working and visiting in recycling grounds.

This can come up with polluting air water and soil and thus results in

This can come up with polluting air water and soil and thus results in an environmental loss.


Metal Recycling is good but not so much cost effective.

Hence it may costs for utility transportation methods, up gradation in recycling units, waste management, chemical expenses, chemical disposal and much more.

In this way building, a new recycling unit takes up a lot of capital.

This also requires School awareness programs and seminar conduction for common man acknowledgment regarding recyclable materials and recycling cycle which will again result in expenses.


In recycling cycle, the recycled products out of recyclable materials do not satisfy us in context of durability, quality, etc.

It is because these recycled product’s raw materials were collected from trash piles or waste mountains which make them fragile.

This problem leads to lowering of recycled product prices and thus shows difficulties in recycling cycle.
