Burn them! And use their coal.
(That is assuming that PFAS does not survive 450°C over 15 minutes)
Googled it. It needs 700+°C. That would make low quality coal, but still doable.

I don't think #OilRecycling is anything near a solution ! Transport should be electric.
But I'm fascinated by the proces. Plastic is a waste, after all [in general].

The second stage is just taking the CO and H2 (syngas) released by the #pyrolysis process and burn them to heat your bricks.
The actual gas released is probably much more oily, dusty and CO2 rich than it would ideally be. A lot of contents will be less pyrolysed and more distilled off the wood and partially burnt -_-
Im not sure, if that has enough energy to run the brick oven.
It may be possible to run that in as additional feed into the oven and keep the normal wood thing.

I think it should be possible, but no idea how realistic it is in the actual setting.
The idea is to have a 2 staged burn:
- Stage 1 is basically a smoke generator. This means it would heat up the sawdust to ~400°C to start the #pyrolysis reaction.
Ideally this means that the wood will basically break into its chemical base components: C and CO and H
If the wood input is dry enough the reaction should be self sustaining but letting in a bit of oxygen can make sure.

I DO understand your point. But there is science for it:
https://www.nature.com/articles/ncomms1053
The CO2 neutral for wood burning is not true, because transport etc makes the whole thing CO2 negative. But #pyrolysis conserves quite a lot of CO2 as pure C. Way more than is needed for transport etc.
So on a decades+ view is CO2 negative for sure.
Your point about it not being CO2 negative short term might true.
I personally use collected dead wood so CO2 should preferable to methane.
In case anybody wants to talk about #biochar or #pyrolysis feel free to ping/DM me.
I'm here to talk about it!
🗓️ On April 1, Dr. Robert Daschner will present new developments and approaches for climate-friendly #plastics in Vienna: The UMSICHT research scientist will give a lecture at the “Biopolymers and Beyond” conference, organized by Biobase. Specifically, he will address the use of biomass waste as a starting material for steam crackers.

I don't have the paper right now, but #pyrolysis could sequester 8% of current emissions. So quite a bit better :-)
It works because plants do the direct air capture. The exhaust from the pyrolysis oven could then be captured much more feasible.
#pyrolysis puts out coal chunks from plants which take CO2 from the air. So not all tech is litterally compressing CO2 and pumping it into the ground.
Another alternative would be to process the CO2 to plastics and then landfill the plastic after use.
Sure it can still kind of leak, but solids leak way less than gases.
i just wanted to note:
#pyrolysis and this should combine well. A oven has an exhaust and that tech could be hooked on that exhaust and sniff like 50% pure CO2
@GreenFire
errr... why not just use plants? I expected it to be satire tbh
plants + #pyrolysis do the exact thing you talk about AND are self replicating AND adapting to environmental changes

Done: Deep dive into commercial metrics - lots of progress 🧮
#TIL: #Methane #pyrolysis is 8x more #energy efficient for producing #hydrogen than water #electrolysis (37.7 kJ/mol H2 vs 285.5) 😮
Grateful: Colleagues who know much more about chemistry than I do 🤓
Our technological innovations for carbon reduction were the focus of a visit by a delegation from the Korea Energy Agency this week. Our head of institute, Christian Doetsch, and Andreas Menne, head of the Low Carbon Technologies department, discussed our research on the industrialization of #electrolysis and #fuelcells, as well as on #bioenergy and #pyrolysis with carbon capture and storage. Other topics included the #Carbon2Chem® joint project and the Fraunhofer flagship project #AmmonVektor.
🗓️ Dr. Alexander Hofmann will give two presentations at the Ministerial Conference on Nuclear Science, Technology and Applications at the end of November in Vienna. He will speak about the opportunities of #chemicalrecycling via #pyrolysis as well as about the potential of electron beamers in pyrolysis.

Non-recyclable waste is a global challenge. One Community’s open-source Highest Good Housing Plan explores sustainable solutions for handling this waste at small and large scales.
For small communities, composting, biogas digesters, and local recycling centers are viable. Large-scale technologies like gasification and pyrolysis convert waste into energy.
