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

Fri May 2 18:46:28 CDT 2008

Jim,

*Olive waste*

1. I'm in contact with an olive oil producer that is eager to use the waste
for generating electricity
2. The resource is 1500-2000 Ton per year(dry)
3. I have estimated that this resource can feed a small gasification system
that will generate 100-300 Kw*h* 360 days
4. To be practical I'm looking for a system that is working on olive waste !
With NO luck
5. If the system is modular we can start with w 100Kwh system and grow.
6. I have looked into the BioMax system but they do not have a project that
is using Olive waste

*Manure*

1. Following the anaerobic digestion of manure for extracting the CH4 to be
used for generating electricity; the solids that are left can be used to
some extent as compost
I'm looking for a gasification system that will use this resource

I heard that in Germany there is a system but have no details if it is
commercial

Do you have the experience with this resource!
