Re: GAS-L: Government gasifier projects...pelletizing

["Peter M Davies" <p.m.davies@bigpond.com.au>]

Dear David,

There is a new innovative super pelletizing technology available from Italy.
These units can handle biomass up to 40% moisture content without auxillary
drying equipment (there is also a "densifier" version for sewerage sludges
and other wet wastes).  Pellets are denser than standard, size range of
8mm-16mm diameters.  Typical bulk densities are in the order of 750kg/m3 and
final moisture content is 8%.  Ideal for gasifier fuel or other projects
which can benefit from uniform characteristic feedstocks.

Currently some development work is being done on pelletizing bagasse in Cuba
using this technology with excellent results.

I have a PDF brochure I can send to anyone interested along with contact
details for your region (I am currently handling Australasia).

Cheers,
Peter Davies

bagasse cogen in the Philippines and need a way to provide biomass fuel
during the out-of-season period.
