A company has provided a possible solution to the global plastic-waste problem and issues surrounding road maintenance – by using recycled plastic waste.
Scottish-based company MacRebur have invented a process that takes plastic rubbish, which would have typically gone to a landfill, and turns it into asphalt that can then be used to repair and lay new road surfaces.
It is estimated the world’s oceans will contain more plastic than marine life by 2050. A stark reminder and ominous sign that plastic waste is slowly killing the planet.
It is, therefore, important to discover new recycling techniques and processes to prevent further plastic waste damage and improve our planets chances of short, medium, and long-term survival.
Typically, roads are made up of 90 per cent rocks, limestone, and sand, with 10 per cent petroleum added to bind the entire mixture together.
MacRuber’s process removes the petroleum from the road mixture, instead it uses recycled waste pellets, which have been created using the collected plastic waste, to bind the asphalt mixture together.
MacRebur turns 684,000 plastic bottles or 1.8 million single-use plastic bags into a one – kilometre stretch of road.
Most of the plastic the company uses is also not conventionally recyclable, and would’ve ended up in the landfill had it not been transformed into pellets for road laying.
The inspiration? Company founder Toby McCartney points to a trip to India where he witnessed locals packing potholes with plastic bottles and then melting them to create that smooth road effect.
