Have you heard of any ways to combat systemic hydrogen sulfide effectively?
There’s this industrial coating called Ecodur 201 that is produced by Castagra that has been showing some good results. I’ve been following a city in Colorado that has used the coating for their manhole covers and it seems to get the job done. As an added benefit, it’s completely green – made from gypsum and vegetable oil.
Company even says it’s edible. Don’t know that I’d snack on it myself. But it does have cold weather applications and is BPA-free, so it hits all of the common points of emphasis most communities have.
Here’s the company site so you can take a look at it for yourself. Maybe it will help?
