But there are of course exceptions and likely many more are growing in response to planetary pressures. One of them is Sea Pigs based in Newcastle who make footwear designed to be recycled. I actually ran into their CEO once on Northumberland Street while giving a public survey on climate change, so thought it worth mentioning them.
Textiles as I learned at the Ending Waste event at Newcastle Helix, have a high carbon footprint, one that is easily ignored by consumers (I have many cloth bags too, just remember to use them for shopping at least 300 times). To really value materials, we need to move to something better – use less and do more with what we have.
A circular economy begins and ends with resource instead of waste, in fact, it doesn’t really end at all. It valorises products derived from natural resources that we otherwise throw away, and which inevitably clog the ecological systems we depend upon for survival. Cities throughout the world are doing more to embrace or at least help along mainly linear modes of material disposal and recycling, shaping them into circular ones.

Looking to the near future — 2019 — there are four topics, four ideas I wish to highlight that could revolutionise not only how we tackle climate change, but many other global challenges the world is facing for sustainable development.
Revolutionise the energy system
Make circular economy a reality
Clean water and sanitation infrastructure for all
Spread electric vehicles
It’s a simple yet powerful (no pun intended) scientific fact that energy underlies everything. If we didn’t have it we wouldn’t exist and without the concept our lives would be radically different from what they are today. But let’s keep it to things like electricity and heat for the moment.
We need to generate more of them and use what we have more wisely, but the energy dense yet carbon heavy materials we’ve relied on since prior to the industrial revolution are a no go for the future. Embarrassingly, they’re on the rise despite progress made in renewables and decarbonisation.
Beyond emissions there were already in place good reasons NOT to burn fossil fuels. Remember acid rain? How about air pollution? Which cities finally seem to be paying attention to again because people are dropping like flies because of air contamination. Did you know that communities downwind of coal fired power stations are more likely to have children with birth defects? How about the impacts coal has on landscapes, water and air, all resources we cannot live without?
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’.
