Just bought a lot of rubber….

@chris EPDM is filled with carbon black. It’ll be a large proportion of the material.
“As with most rubbers, EPDM as used is always compounded with fillers such as carbon blackand calcium carbonate, with plasticisers such as paraffinic oils, and has functional rubbery properties only when crosslinked.”

Here's some info I found from Dow on a new process they say *reduces* various polluting factors by ____% but of course they don't give absolute numbers because then we would have actual information.

@chris There will be some amount of carbon in the polymer, and then the carbon black filler.
DOW might be able to tell you the carbon content if the thickness of the material size of the sheet are known.

@RandomCanuck it's standard “45mil” (1.14mm). Super common. The info must be out there somewhere.

@chris EPDM: 6.93 kg CO2 / sq. ft. for the 60 mil sheet used in roofing. So 45 mil would likely be proportionally less.

@RandomCanuck nice! I can work with that!

Big thanks to @RandomCanuck for finding a CO2 answer!
This document (https://epdmroofs.org/wp-content/uploads/2021/08/08-ERA-Technical-Bulletin-Overview-of-EPDM-design-option-3.pdf) says standard 60mil* EPDM roofing membrane embodies 6.93kg of CO2/sqft.
So 45mil (1.143mm thick) will be 25% less:
6.93-25% = 5.198 kgCO2/sqft.I bought a 70ft x 30ft section.
So 2100sqft x 5.198 = 10,915.8 kgC02**That is equivalent to flying from #YVR to #HKG roundtrip, 13 times. Oooooff. That's a bit of a shocker. 🫢
OK, I guess I have some work to do to offset/capture some carbon in this here little pond/pool! The good news is, it will not feature any fish so I am hopeful that it will be, eventually, a carbon-negative operation as long as I plant it chock-full and periodically remove/sequester the compost to avoid methane emissions from decomposition.
*WHAT A STUPID MEASUREMENT lol “60mil” = 0.060in or 1.524mm thickness
** Holy heck I love the built-in math in the latest macOS/iOS update!!

PS. There should be a carbon tax on this stuff!

@chris @RandomCanuck Obviously the die is cast in your case, but are there good alternatives to rubber liners for garden ponds? Maybe something like a clay layer?

@dx @RandomCanuck I haven't seen any that are truly water-tight.
