Why is it more sustainable to use recycled Aluminium?

Benefits of recycling aluminum cans

Mexico is a country where aluminum collection and recycling is relatively efficient compared to other countries. Although the country is not an aluminum producer, recycling the metal has allowed the industry to develop.

The high recycling rate is due to the fact that Mexico does not produce aluminum for cans. Therefore, it has to be imported from countries such as the US or Brazil. So one of the ways to reduce these imports and the costs they entail is to reuse aluminum.

Clogged drains represent an imminent risk of flooding during the rainy season, the accumulation of waste dragged by the water causes the obstruction of the drains, which is one of the main reasons for the puddles every time there is a rainfall. In addition to remembering not to throw garbage in the streets.

Before the rainy season in Mexico, it is important to prevent flooding. Therefore, cleaning of drainage networks and clearing of sewers and canals in the city so that they are free of garbage, dirt and debris must be carried out so that rainwater can flow properly.

What can be done with recycled aluminum

When aluminum is exposed to air and moisture, an oxide layer is formed that protects the surface from further oxidation. This self-protective oxide layer gives it the resistance it possesses against deterioration due to atmospheric agents or industrial environments. Anodizing treatments can also be used to improve the resistance of the surface oxide layer.

Aluminum conducts heat and electricity excellently. The thermal conductivity of aluminum is approximately 50-60 percent of that of copper, which allows its application in the large-scale production of cookware. Thermal conductivity refers to the transfer from one medium to another; therefore, aluminum heat exchangers are used in the chemical, food and aircraft industries. The high conductivity of aluminum (1350) reaches approximately 62 percent of the international annealed copper standard (IACS) and makes it a good electrical conductor for one third of the specific gravity of copper.

The shift from a linear to a circular economy is very positive not only for the planet, but also for the economy. It reduces the need to constantly extract raw materials, which means lower costs, emissions and waste. The key is to transform the “make-use-dispose-dispose” process into one in which waste is converted into resources to create new products. Working towards the goal of zero waste is an essential commitment to combat the climate crisis to which increasingly large sectors of industry are committed. To achieve this goal, the commitment to a circular model is fundamental.

But the advantage is also economic: by eliminating dependence on raw materials, price rises and their volatility are avoided. Circularity also guarantees the supply of materials without reducing natural resources. What’s more, the circular economy is a source of quality employment that continues to grow.

How to reduce aluminum

Aluminum is a material that has been used for a long time for different purposes and utilities. Something very important to highlight has to do with the fact that, since the beginning of the 1990s, the energy consumption necessary for its use has been reduced by up to 70%.

This represents an invitation to the different national governments and societies to work together with the industry to generate waste collection and separation systems that are really efficient and that can protect aluminum. This will substantially improve the recycling rates of this material, which is so important for the future of the planet. The aim is to generate a new circular model, where aluminum can be reused over and over again.
