The streets of South Africa will be redone with recycled plastic bottles

The streets of South Africa will be redone with recycled plastic bottles

In South Africa, recovering recycled plastic is a more than feasible way. Indeed I would say a highway. Here's why.

In the fight against climate change (which we fought really badly again this year) no action is too small or unimportant. And after the experience of plastic road in Holland, now it's getting serious.

The latest initiative comes from South Africa: plans to build sidewalks totally made from recycled plastic from used bottles are intensifying.

The great recycling

Shisalanga Construction, the company that will handle this repaving, already has a little experience. He redesigned more than 400 meters of road in Cliffdale, on the outskirts of Durban, using this special asphalt. To do this, almost 40.000 two-liter plastic milk bottles were recycled.

Recycled plastic milk bottles? Better than asphalt

The company uses high-density polyethylene (HDPE), a special type of plastic usually found in milk bottles. This plastic is transformed into pellets in a local recycling plant.

Each ton of "asphalt" made from recycled plastic contains approximately 118 to 128 bottles. And to Shisalanga Construction They say the production process produces less toxic emissions than conventional methods. Can we believe it?

Not only that: a more durable and water-resistant asphalt comes out of recycled plastic. The material is capable of withstanding temperatures of up to 70 degrees Celsius and up to 22 degrees below zero.

High performance, away the garbage from the world

Even if the cost of production is the same as the previous methods, the roads built in plastic asphalt allow to recycle this damned matter and should last longer, saving money for the city.

The Department of Transportation of the KZN, the body responsible for commissioning the plastic project, appears to be affected by the results.

Ducasse kit, control technician at the KZN Department of Transportation, told CNN: “It works really well. Time will give us further confirmation, but what I've seen is already great news ".

The department commissioned a viaduct to further test the material. And in the meantime, Shisalanga has contacted the National Roads Agency (SANRAL) of South Africa to lay an additional 200 tons of recycled plastic asphalt on the country's main highway, the N3.

Until we find a way to dissolve it safely, it is better to walk on the recycled plastic than to end it in our stomach or nose.
