[Digestion] Digestion of Oily Seed cake

Thu Jul 18 09:47:25 CDT 2019

Gentlemen, 

I also just came across a lovely paper which describes some biofiltration of
the air around the seed cake storage.
http://erem.ktu.lt/index.php/erem/article/view/676/1296

Because I have built these in times past industrially, but wasn't thinking
enough out of the box, I remembered that in the wastelands in front of us,
there are woodburners who make coal in the traditonal methods using dirt
kilns. There is lots of coal bits and carbonised soil left over from this
process. I have sent for some amounts of this material, to cover the smelly
portions of the mass, AFTER I have doused it with some probiotic liquids
that I will make. I was glad to see the use of the word probiotics in this
paper, biology that is beneficial to man, and used to destroy bad smells in
this case. They even suggest optimal depths to cover with to control the
smell, as the VOC's waft through the cover, they are chemically and
biologically attacked and destroyed! Great stuff....

Thanks for the brain jogs!!

Gday Paul,

I take your caution to me regarding the stewardship of the methane produced
seriously. Thanks for that reminder.

I was really thinking of something to spray on maybe to do a odor knock-down
quickly that ill not "add" to the smell, but Alam's idea of going further
and placing it in a controlled space, as in a bag, may be the way out for me
 I am going to use what I have today to create a microbial slurry to try and
knock down this smell.

With thanks,

G'day Mike et al,
I have no personal experience with oil cake but have heard that you must
only feed limited amounts of things like glycerine (and oil cake?) or you
will kill the digester.
For quickest response I would suggest a visit to your local sewage treatment
plant to get some AD sludge (if they have an anaerobic system), or use cow
or pig manure or septic tank sludge as an innoculum.
You will of course have to capture the biogas and burn it off, as methane is
23-26 times worse as a greenhouse gas than CO2.
Hope this is some help,
Happy digesting,

HOOROO

Thanks for all that you have done for Biogas Paul and others.
I have been a member here for years and have benefitted much from the
correspondences that I have garnered here.
Glad to hear a message here again... I believe Facebook took a lot of wind
out of the list-groups "sails", back in the day, to the point that not many
list-groups still remain active.

Anyhoo, ...

Have a question that I wonder if any member has dealt with. Have a situation
where, after storing waste castor seed cake on a compost pile for a few
years we had to move it, or stir it up, to make way for an aquaponic system,
and it is stinking fiercely, much to the dismay of my neighbours. I realise
that the oil has seeped down over the years into the core of the mass, and
the outer sections have been burnt dry by the sun and less smelly.

Am thinking real short term help with bio-digestion to the rescue. Am
thinking of brewing a quick batch of bacteria, which can quickly eat and
digest and belch off, this stuff, so that it will not smell as bad as it is
doing right now. Does anyone have experience with this oily seedcake mass,
which I cannot place into a bio-digester right now, I was storing it in the
hope of having this as a high yield in-feed mass. 

Can anyone give me some renegade help with brewing a bio-assistance brew, to
kill this stench down quickly please?

I have sufficient containers and warm water, so I can do a batch brew with
some help. 
Would regular human probiotic tablets for indigestion be a good seedstock to
start this brew to kill the smell, or does someone who has processed oily
seedcakes have a better idea?

I am grateful for all help on this matter.

G'day All,
There must be some very patient people out there!
I am a (very inactive for quite a while) member of the following LinkedIn
Groups

Go to https://www.linkedin.com/feed/ and join (I hope it's still for free!),
then look for the Groups (and there may be more by now!).

Happy digesting,

HOOROO

P.S. If an Admin for the list sees this can you please e-mail me the Admin
password as the "Signature" needs updating?
