[Gasification] indirect gasification schemes (was: Alternativeenergy in the nursery)

Ron, 

Please tell me more about what you are looking for. My company, Ecovolve Energy is developing a small scale biopower system with olive and grape pits as well as manure as our primary feedstocks. Would be happy to discuss further if you're interested.  

Best regards,

Jim,

I'm looking for specific gasification systems that are commercial and can
use the following resource:

1. Olive waste - left after extracting olive oil in cold process
2. Waste left from manure - following anerobic process that extracts the
Biogas
