Has anyone ever used drywall gypsum as fertilizer? I have a tons of scrap that I want to compost. If it can be used does it need to be composted before use, or can I just crumble it up and top dress?
It has asbestos in it. The older stuff and the new stuff. I would never use it to grow MMJ.
pellatized stuff riteHey kolah you're post reminded me of that commercial where the mom says to her family "it's got radon in it!" lol great info bro, I had some boards around here I was about to crush up, I saw a bag of fast acting gypsum for 5 bucks at the hardware store!
Wallboard aka drywall aka gypsum board aka sheet rock are all the same animal. As I said, the old stuff is laced with asbestos and so is the new shit. The US (supposedly) banned US factories from putting asbestos in their drywall and in their drywall mud (aka wall compound). BUT you can buy the shit in any US store because they ship it in from Mexico and Canada which still has asbestos added to it and it is sold here everywhere. I do not think there are any USA factories making the stuff anymore.
BTW if your house is tested and found to contain asbestos wallboard (or mud) it is considered a HazMat emergency and say goodbye to your nice little house that is now toxic and unsellable on the market. The same goes for that popcorn ceiling texture that was all the rage back in the 80's. All shit.
Here in CO most insurance claims have a strict policy and will send out an inspector to test for asbestos on the walls before doing any remodel or tear down work. It can not be in any school or daycare buildings either. What baffles my ass is that the US supposedly bans it but allows it to be imported here for sale and usage.
dry wall guy here. Murco products makes mud in the u.s. still. They have a factory here in southern colorado.
Now im not trying to arguing with you. but i have bid, managed and done alot of drywall in schools, colleges, military installations, day care centers, va hospitals, regular hospitals, insurance claims, new construction, remodels, etc etc. and have NEVER seen or heard of a test for asbestos in drywall board or mud. Now as far as board imported from other countries, I have seen alot of Chinese drywall. And have had to take down rock that was found to be from china, after it was hung. This is my experience, and if it is standard procedure to test for it. I would of known about it.
