Recycling of metals

a) What will happen to the world if there are no more metals?


If there are no more metals, we would not have the material to make many things like tools and machines, including airplanes, cars, and hammers. We will lose convenience when we do not have these things. Metals are very important because they are used to make many essential things in our lives.









b) Is it important to recycle metal?


Yes, it is very important.A great amount of energy can be saved in using recycled metals. In fact, the energy used is reduced by 95% for aluminum, 85% for copper and 74% for iron and steel compared to using raw metals. It is important to recycle metals as any metal ending up in landfill is simply a waste of valuable resources.




c) What are the reasons to recycle metals? Isn't it easier to obtain metals through its original form through extraction of metals? In the recycling of metals, what are some of the effects it has on the environment?



No it is not easier to obtain metals by extracting them from their original form.
Below are some reasons to recycle metals.

It takes a lot less energy to melt waste metal and recycle them than it does to produce new metal

Using recycled metal reduces CO2 emissions which can cause global warming

It reduces the need to mine the raw materials required to make the metal such as Iron ore for steel and nickel for stainless steel.

It reduces the amount of metal going to landfill as a lot of household metal waste from cans is still ending up in landfill sites.

Recycling metals is one way of protecting the environment by conserving scarce natural resources and reducing pollution on the surroundings.It also helps save energy as recycling scrap metal uses less energy than extracting the metal from its ores. 

d) Think of reactive ways that we can also play a part in recycling metals?

What are some of the ways in which recycled metals are used in our life?

We should not throw away aluminium drink cans and other metal items, instead we should dispose them in metal recycling bins. We can reuse unwanted metal items for other purposes, such as making decorations or furniture.

We should keep metals items as long as possible instead of throwing them into bins. 

Scrap metals are used to make some steel which are then used for building constructions. Scrap metals can also be used to make high quality steel tools. A more commonly seen use of scrap metal is the aluminium drink cans and canned foods. The use of scrap metal has become an important part of modern steel-making industries, improving the industry's economic viability and reducing environmental harm.
