Hello rgh,
I gather from what you say that there is a new team trying to revive the process. Is this something you have evidence of, or are you speculating? Thanks
Here is a quote from your post:
It's clear at this point that Rivera's SSTP brand is dissolved and that the new team involved is using their equity to explore alternate biochemical processes for catalyst (separate to the Rivera Process) to generate biodegradable fuel. However, it's pretty clear that (1) they don't have enough funding from domestic or international ventures or (2) they do not have a copyright patent on the process unique from other companies already exploring it.
