Recycle, recycle, recycle: but how much is recycling worth, understood as action and the result of recycling? That is, how much it saves us in terms of positive impact on the environment? A lot in truth, probably more than we think. In fact, recycling does not only mean saving raw materials, but also energy saving and less pollution because the processes necessary to restore life to a material are generally less energy-intensive than those required to produce the virgin material.
A few examples. To recycle thealuminum only 5% of the energy that would be needed to produce it from bauxite (the main original raw material) is sufficient.steel obtained entirely from scrap, energy savings amount to about two thirds. The glass recycled saves up to a third of the energy needed for the original production process.
The recycling of materials it is also a means of reducing land, air and water pollution to acceptable levels. Returning to steel, producing it from scrap instead of virgin steel reduces air pollution 85%, 76% of water and completely eliminates extractive waste.
Recycle the paper (which can also be the basic material for producing insulators that can be used in construction) can reduce both the amount of waste that presses on landfills and the impact on forests in direct proportion to the amount recycled. Furthermore, the recycling of paper reduces the pollutants emitted into the atmosphere (74%) and water (35%), especially if excessive whitening treatments have not been done.
