They design material for roads with recycled masks | Digital Trends Spanish


Facial masks have become the fashionable accessory in recent times and we all know that it has not been for aesthetic reasons.

This implement protects us from the coronavirus and has helped us reduce infections; the only problem is that, due to their massive use, many have ended up as garbage, which has increased the levels of contamination.

In fact, an estimated 1.56 billion masks ended up in the seas last year, exposing serious environmental damage.

Fortunately, technological advances can give us a hand to better manage the masks that we have already used.

Now, for example, scientists at RMIT University in Melbourne, Australia, have developed a method for transforming masks into road material.

How they did it?

The researchers mixed the single-use shredded face masks with processed construction debris to craft the final material that would meet civil engineering safety standards.

According to the authors of the study published in Science of the Total Environment, three million masks would serve to pave just under a kilometer of a two-lane highway. This would prevent 93 tons of waste from ending up in landfills.

It is not a small thing, since 6.800 million masks are used every day.

To carry out their research, the scientists used processed construction debris, also known as recycled concrete aggregate or RCA, used regularly as a base layer for roads.

According to the study, the masks improved this material: they gave it more strength and maintained cohesion.
