A Cambridge University team made the device with simple materials using a paint sprayer—offering a possible dual fix for plastic pollution and dirty hydrogen production
It’s pure plastic waste at that point. No one is going to be making plastic bottles for the purpose of dissembling them into hydrogen fuel anymore than they are currently making plastic bottles for the purpose of sending to waste-to-energy plants (incinerators).
It’s not just plastic. It’s plants too; ideally agricultural and industrial byproducts.
Solar reforming has emerged as a class of sunlight-driven technologies capable of converting waste-derived substrates into fuels and chemicals. By utilizing substrates such as glucose or ethylene glycol (EG), derived from lignocellulosic biomass or polyethylene terephthalate (PET), as electron donors, solar reforming enables a more energetically favorable oxidation pathway compared with water oxidation.

It’s also burnt to make cement. Or just burnt, in Spain “mysterious fires” in sorting/recycling plants that only affected the plastic trash were pretty common after China stopped importing ship containers filled with mixed and unrecyclable plastics. I don’t know what is going on now, blessed ignorance, fuck reality.
It’s still in the world, instead of a hole in the ground, and will go CO² the next opportunity.
This is the problem with oil; no matter what steps you do inbetween (be it fuel or plastic, or recycling/processing the plastic), it will still accelerate climate warming in the end.
Carbon. The stuff that prefers to be in a gaseous & bound form to do heat house effect, which we take out of the ground where it got to in times with significant warmer global climate.
The hydrogen comes from plastic so it’s arguably not “clean” as it still comes from fossil fuels.

Bad news: over 90% of plastic with those recycle tags end up exported and burned to make electricity.

Better than letting the plastic pile up.
But the C doesn’t disappear.
According to the original paper, the C goes into “value-added organics such as formate, acetate, glycolate and glycolaldehyde dimer.”
So specifically not carbon dioxide, which is the problem gas.

Oh noes not the C!
What is “the C”? In this context
Carbon. The stuff that prefers to be in a gaseous & bound form to do heat house effect, which we take out of the ground where it got to in times with significant warmer global climate.
Agreed but at least if this is scalable, it is a solution to one problem.
