Making plastic waste history with cold plasma

Plastic wastes are a global problem. If you’ve been following the series of environmental horror stories in the media this year you know exactly what I mean. It’s bunk.

Even undiscovered species living in the deepest parts of the ocean are contaminated with plastic. Because humans bioaccumulate plastic from the environment, especially animals we eat from the sea like fish, we are sadly far from safe in this rather disturbing cycle.

At the time of writing there is no safe threshold for consuming plastics and research on whether eating plastic in certain quantities has ill health effects is ongoing. Time will tell. But in the meantime here’s an idea that may interest you:

We could prevent the majority if not all (optimistic here) waste plastics from entering the land and sea by using them as a resource.

How? One of the answers may lie in the ever so humble ‘cold plasma’.

Now before you turn your nose up and decide ‘that’s way too gross for me to handle right now’. I’m not talking about blood plasma. I’m referring to the fourth state of matter that we humans call plasma. Most of the matter in the universe is in fact plasma. I will save this epic tale for another time, but I encourage you to read about plasma here.

Ok, to put it simply, physicists define plasma as an ‘ionised gas’. But wait…I thought it was something different? It is, because in plasma electrons break free from their atoms and become highly energised. And once they do they are capable of amazing things like (wait for it) breaking down plastics into things that people use, which goes a step beyond ‘recycling’.

The future of transport – faster, integrated and electric

The future of transport was the topic of discussion at a Café Scienitifique in the Urban Sciences Building at Newcastle Helix, part of a series inspired by the 2018 Great Exhibition of the North in Newcastle. Are we fast forwarding into a future of efficient and sustainable transport for all, or are we stuck in a combustion powered dystopia for the foreseeable future with climate change nipping at our heels?

Cities are implementing smart traffic lights, rapid EV charging points, testing autonomous vehicles and flying taxis. Countries are promising to phase out internal combustion engines by 2040 or sooner. In response to this ambitious policy, many of the vehicles on the road could be electric.

Transport by rail will change, becoming faster, more sustainable and (hopefully) more affordable. With 60% of all current travel taking place in urban areas rail is likely best placed for super mass transit systems.

The remit of the Helix is to make our lives smarter, healthier and sustainable, combining cutting edge university research with business, industry and local communities. It is transforming a former brownfield located in the centre of Newcastle into a thriving hub for commercial enterprise, residential development, urban science and innovation. Transport is very much part of its vision for the future. Continue reading The future of transport – faster, integrated and electric
