[Digestion] vermiculture of digested solids

[Theo Bijman]

Dear readers,

 

Referring to the question about vermiculture.  Why should you want to
use vermiculture when you have already digested solid waste that could
be applied to the fields directly? With raw manure, I could see the
advantage, as you would get a somewhat dry, concentrated and easy to
apply organic fertilizer, without the acidifying effect of manure. Is it
the reduction in volume that is an advantage?  Or are people used to
using vermiculture organic fertilizer and do not know the usage of
digested solid waste? Maybe somebody has some thoughts about this. Do
you apply liquid waste to the composting heaps  (the liquids which
remains when separating digistate into solids and liquids?) to keep it
moist?

Thanks

Matt and listers, Hello,

There are two projects in South India doing vermiculture of digestate:
SKG Sangha and VK-Nardep that have been highlighted on the list, as they
both won Ashden Awards. There are videos available for both projects,
although the one for VK-Nardep is a sequence of still photographs taken
at the time of the judge's visit.

The Ashden Award links are: www.ashdenawards.org/winners/skgsangha
<http://www.ashdenawards.org/winners/skgsangha>  and
www.ashdenawards.org/winners/vknardep
<http://www.ashdenawards.org/winners/vknardep> . A direct link to SKG
Sangha is: www.skgsangha.org <http://www.skgsangha.org>  and to
VK-Nardep is: vknardep.org <http://vknardep.org> .

Regards,

David Fulford

There was a project mentioned on the list (maybe a year or two ago)
about a vermiculture project using the digestate from a biogas plant.  I
think it was in India.  I think they were using sawdust to soak up the
water and composting it for a period of time and then introducing the
worms.  I can't find the link now.  Does anyone remember what I'm
talking about?  Or does anyone have any info about vermiculture combined
with biogas?
