Parker Dale, Hi
With the flurry of confused e-mails over moving of the list, I think
your e-mail was not seen.
What to you mean by coffee production wastes? Do you mean processing the
wastes from recovering the coffee beans, or the wastes from making
coffee beans into instant coffee?
There has been some work on the digestion of the pulp from the berries
that surround the coffee beans. There are two ways that the berry pulp
can be removed. The wet process results in an acidic slurry that can be
difficult to digest. However, if it can be added to a working continuous
digester along with other feed stocks, it does give very good gas
production.
The dry process (sun drying the berries and then using a rice huller to
remove the outer layers) results in a husk that can be made into a
slurry with water that seems to digest easily. I had a student doing
some tests a year or two back and she obtained much better results than
I expected from laboratory scale tests.
I hope this helps. Others on the list will probably give you more
information.
Regards,
David F.
