Question

write the ways how we conserve aluminium ​

Answer 1

Answer:

• Melting down aluminum cans takes much less energy than smelting ore to make new aluminum. Plastic can be recycled instead of using precious natural reserves of oil to make new plastics. Any thing that reduces the amount of energy that a person uses will benefit the natural resources.

• The contribution of recycled metal to the global output of aluminium products has increased from 17 percent in 1960 to 34 percent today, and expected to rise to almost 40 percent by 2020. Global recycling rates are high, with approximately 90 per cent of the metal used for transport and construction applications recovered, and over 60 per cent of used beverage cans are collected.

• Aluminium does not degrade during the recycling process, since its atomic structure is not altered during melting. Aluminium recycling is both economically and environmentally effective, as recycled aluminium requires only 5% of the energy used to make primary aluminium, and can have the same properties as the parent metal. Infact, aluminium can be recycled endlessly without loss of material properties.

• During the course of multiple recycling, more and more alloying elements are introduced into the metal cycle. This effect is put to good use in the production of casting alloys, which generally need these elements to attain the desired alloy properties.The industry has a long tradition of collecting and recycling used aluminium products

these are the some ways you could conserve aluminum.
