[Digestion] Re Trees for the Future.

  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.
