Yeah, that is a whole other discussion.

"Agrarian and agrifood systems are responsible for approximately one-third (29.7%) of total global anthropogenic greenhouse gas emissions, which amounted to 16.2 billion tonnes of CO2 equivalent in 2022.  While CO2 itself is the most significant gas by volume, agricultural activities are the primary driver of methane (CH4) and nitrous oxide (N2O) emissions, which have much higher global warming potentials.

At least there is CO2 filter technology in process.

How exactly does that compare to non human greenhouse gas releases world wide? You know, volcanos, wildlife (termites in particular), rotting vegetation from the leaves falling in the fall, etc...

Please compare the two sources.

All the sources are there for you to do your own research, have at it and then get back to us and we will see if the resulting data is worth discussing.

Your link has no listing of natural sources of greenhouse gasses. You brought it up.

I didn't bring up the comparison questions you want answered. I simply said your idea that Exowatt's unit is heating up the environment was wrong.

I did some searches and there are no easy to find numbers on natural emissions of greenhouse gasses, only human sources. It is like they are hiding them. Are they frightened of the numbers.

Could be, but I am more interested in posting about the innovations to hopefully tackle the lowering of emissions, however they may be created. As well as other innovations that reduce poisons and costs for the people, all life, and our planet.

I am interested also and appreciate your efforts to highlight new technology and innovation. BK does have some good points about the plastic recycling, so it seems we're still a long way off. On the CO2 filter, I read the links and it seems it doesn't work like a traditional air filter...the technology absorbs the CO2 but will "fill up" and the CO2 must be removed, condensed and recaptured all of which takes energy. Plants are the best at removing CO2 by converting it into carbohydrates like sugars. And for BK... plants extract oxygen from water, release it as a waste and use the hydrogen to convert the CO2.

Here's what I could find on homeowner's energy saved and energy required to regenerate the filter.

"Researchers at the University of Chicago have developed a carbon nanofiber filter that not only captures CO2 from building ventilation but also reduces HVAC energy consumption by up to 21.66% by allowing buildings to recirculate indoor air rather than pulling in conditioned outdoor air.  The energy required to regenerate the filter is minimal, achievable through solar heating or short electrical pulses, resulting in a net carbon removal efficiency of 92.1% and a cost of $362 per ton of CO2 removed when using solar heat."

Looks good to me!

I want one.

Well BK did point out that Chinese company wasn't what I initially thought it was, but there does exist companies that do solvent-based plastic recycling.

----

"Solvent-based extraction and purification is a recycling method that dissolves plastics to remove contaminants like dyes, additives, and odors without breaking the polymer’s chemical bonds.  Key companies actively commercializing or developing these technologies include:

• PureCycle Technologies: Utilizes solvent-based purification to remove impurities from polypropylene (PP) waste, producing virgin-like resin; their first commercial facility in Ohio began operations in July 2024. 
  
• APK AG: Deploys its proprietary Newcycling® solvent-based process to separate polyolefins (PE and PP) from mixed plastic waste, with a third commercial-scale facility in Germany completed in September 2024. 
  
• Polystyvert: Specializes in dissolving and recrystallizing polystyrene (PS) waste to create clean recycled resin with properties similar to virgin material. 
  
• Sulzer: Provides industrial equipment and DEVO™ technology for efficient solvent recovery and purification in solvent-based recycling processes, particularly for shear-sensitive polymers. 
  
• CreaCycle / Fraunhofer IVV: Developed the CreaSolv® process, a selective dissolution technology used by partners like Unilever to recycle polyethylene and polypropylene. 
  
• DePoly: A Swiss startup using a chemical solvent process to convert mixed polyester (PET) waste into virgin-grade precursors like purified terephthalic acid (PTA) and mono-ethylene glycol (MEG). 
  
• Banyan Nation: Uses proprietary solvent-based cleaning technology to remove inks and coatings from plastic waste, producing custom recycled resin grades. 
  

Other notable participants in the solvent-based recycling market include Eastman (which combines molecular and solvent-based approaches), Solvay (which previously operated a PVC recycling plant), and Procter & Gamble (which invented the solvent technology later licensed to PureCycle).  The global solvent-based plastic recycling market is projected to reach USD 965.10 million by 2030, growing at a CAGR of 6.4% from 2024."

Those are some deep pockets, would love to see a solution for plastic recycling, right now the market is too inconsistent after the geniuses that run our cities went to single stream and set back the industry decades....
