Hi Randy,
This is just what we are looking for, what's the name of your Danish
supplier?

We will use a chopper that also sanitizes them to 70 degrees. No problem
with that from the site that we visited in Denmark doing it. But we need
some confirmation of the gas numbers to be safe.

Dear Randy,

Be careful using chicken feathers as a feedstock for ADs.  We had a swine
farmer in Brazil that was slaughtering chickens onsite and mixing the
feathers (without our knowledge) with the animal waste (AD influent).  We
had so many problems with plugged pipes (effluent).  We open the anaerobic
digester to fix the problem after several unsuccessful attempts to unplug
the effluent without opening the AD.  After opening AD we realized that
chicken feathers were plugging the pipes.  As a matter of fact the feathers
formed a very hard crust on the top surface of the AD.   

Your AD set up may be different that our AD system, for this particular
farm, so here is some info on our set up:

1.            Ambient temperature covered lagoon

2.            The feather were not chopped or grinded before entering the AD

3.            No mixing

4.            Influent feedstock - designed for swine waste

I hope this info helps!

Apparently however that is removed is not cost-effective, at least, in
Poland. We have multiple poultry processing plants trying to get rid of
feathers.

G'day Randy et al,

As chicken feathers are Keratin they may be worth a lot more as Keratin than
as methane.

Happy digesting(?)

Hi folks! We are trying to get more verification of our assumptions of
methane production from chicken feathers. Anyone have any data?  Thanks!
