Hey bb,
Looks good to me. They have a combination of "critter' and enzymes in their products that they use to break dwon and consume yucchy environmental stuff.
I don't think it's rocket science, as both have been used for years in the waste treatment industry. But, they have probably formulated it in such a way as to make remediation efforts easier.
Anything that helps, aye. Cheap too............!!
John :-)
