All,

OK, I must admit to being a bit perplexed by how all of this works, but the headline – The Newest Airline Climate Solution? Burying Sawdust – did catch my eye.  This is another of those Wall Street Journal articles with the “gift link” that Kathy and I can provide.  The article is about my employer, so after I post this I am going to go and reread it.  LOL

Enjoy,

Phillip

Interesting…

I did a google Search on the Topic of Carbon Capture and Storing of it.
I assume the Sawdust is not on the airframes themselves, rather the airline would fund sites that use the Sawdust technology as a medium to store the CO2 as it is the most cost effective solution at present.

However, this field of Co2 Capture is way outside my area of expertise 🙂

In my air force career I did work on a few airframes that used something like a Catalytic converter
to filter air outside the airframe before it was used for breathing and pressurization within the air frame.
And of course those crews also had O2 available.

Work or handling of the filters within these converters was considered Hazardous and required a Full HazMat suit.

Of course I have yet to have seen any publicity as to if North America was to manage zero CO2 emissions within the next ten years
and Asia continues to unless it’s unlimited amounts of CO2
will the Earth be in any better shape in 25 years ?

Of course that last comment leads us to a much broader discussion,
which is a whole lot of Doom and Gloom.

Cheers!

Steve,

Thanks for the follow up.  The article informs the reader that AA is buying these blocks that are then buried and their carbon absorption is able to be monitored and measured.  They don’t ever go anywhere near a plane.

The filters you are talking about are probably early attempts at ozone filtration.  I don’t know much about the technology, but most airliners have ozone conversion, sometimes incorrectly called filtration, capability.  The few that don’t these days, they may be dispatched at a different altitude to keep them out of a high-concentration ozone altitude.  Here is a link to a paper that covers the topic and explains how altitude may affect ozone concentrations.  For a fact FAA regulates how much ozone can be in the cabin air under 14CFR 25.832.

That is pretty far outside of my area of expertise, but because of the FAA regulations cabin ozone conversion is done by a lot of airliners.  The A320 family of aircraft that I fly has ozone conversion equipment as an option and AA planes have it as I understand things.  Here is a link to an article that Airbus published on cabin air quality.  A lot of work has been done on the topic in the last few years.  Again, carbon generation and reduction versus ozone and cabin air quality; two totally different subjects, but there is an intersection to the the degree that aircraft in general and airliners specifically are all getting a lot of attention with respect to both these days.
