Engineer Toby McCartney explains how his Scottish start-up MacRebur is persuading councils to use local waste plastic to build roads. Two English councils have already started building roads this way. A smartphone film for BBC World Hacks by Dougal Shaw..

Who goes out of their way to tell everyone that they will never reveal how they make the product? Seems fishy. Also still a start up and only used in one small town. So basically untested? Guess BBC is in the click mining game. Was hoping for something a little bit more substantive from BBC.
Its not you palstic road recepy.... India was the first country to develop this technology to use waste plastics for road and build 33 million kilometers of road by 2008.. And now in ur video u r showing india in a bad way and taking credit of the technology that u inevented it... Gosh! Thief and a lier..
As we all know plastic products are varied and have numerous advantages and we all enjoy the utility of the products made from the material. Though we r quick to claim any credit for developing technology for recycling the product, our track record in collection and recycling of the waste in kerala and india is hopelessly ineffective and uncoordinated. We can see that the landscapes and waterbodies r defaced by the waste. Atleast i can say that the wastes gathered by me from household and public places around could not be disposed off for years now for want of a system for disposal of the waste. We consumers, producers and the administrations r equally at fault for gross and pathetic failure in this regard.
Prof.Rajagopalan Vasudevan in 2002only has laid plastic roads and concept conceived in 90‘s.since then he is working on it and in 2002 laid the first road in Chennai.. And he is the Man behind this idea... He is the "Plastic Man Of india"...
this is stupid, if you would gone to at least one chemistry lesson in year 11 you would have known that bitumen is already a waste product of distilling crude oil, so what is the point of wasting extra energy my melting down plastic and embedding it into the asphalt when we could just use bitumen, which i am sure would make up a more resistant road.
Saying that using plastic in roads is a good way not to create waste plastic is assuming that roads are permanent. The reality is you've found a large scale way to use plastic, and when the day comes that these roads need to be replaced or renovated then you've got a crap load of waste plastic. I don't feel like it's a particularly good idea to find a new way to use a non renewable material on such a large scale. And do you think it'll really be good to live in a plastic city? No thanks.
Typical British, still stealing from India. the idea from Indian scientist and India built allready 1500km of road. this idiot says his idea and more over he blame India for plastic and potholes daam. India like this because of your ancestors idiot. now you are stealing the knowledge and claiming your idea. Cunning FOX..cheating is in your genes Britts..
The issue is, the plastic remains and even worse was that plastic bags he was using to transport the pellets... @2:51 which is just making more plastic.
Is it really a solution to the problem or a temporary band-aid that will also become a problem in the future. What happens if someone burnt the roads? do they melt.. produce a toxin, ect ect. Any important questions answered or asked?
Building roads may not be the main thing that will save our planet but it is one huge step in the right direction. We build roads every day and recycling plastics would both reduce cost and solve plastic waste. If 100 people work together to reduce plastic waste in such brilliant and innovative ways, the world will change for the better.
I saw a news program that claimed disposable tires which are a major problem can be used to pave roads and last a lot longer than conventional asphalt. But the road construction lobby has blocked it from being used because its durability would cut into their profits. If any one can confirm this, please share.
the medium such as rock or plastic is not the problem but the bitumous itself is the problem because roads get potholes and cracks not becuase the tinign rocks break and crack but because the bitomous gets cold and cracks, to solve the road repaving problem you will need some sort of more flexible bitonimus, or a flexible glue or epozy road to bind the medium like rock and plastic. plastic roads will expand and contract just like rock roads and they will crack and get potholes becuase the bitumous is the problem not the medium...add silicone or somthing to the asphault so it can stretch and not crack in cold weather.
so professional and titillating. uuuummm.... saving the planet... wouldn't the lowest hanging fruit be.. air travel? which explains a lot of stuff such as how we got to where we are... and that plastic stuff is merely short term mementos for the universe to lament the loss of all things eukaryotic. a food chain this time, not food supply nor plastic junk.
This is the most stupid idea. Any plastic that is non biodegradable is very dangerous. Now if we made that into road, the micro plastics are going to enter food chain even more faster. People don't think long term impact before acting. Stupidest idea ever.
Terrible video - where is the analysis? How long does it last? How does it compare to regular roads? Cost per km comparison? Any adverse environmental effects in the processing of this material? Do micro-plastics leech into the environment at all?
