Hi all,<br>
<br>
in Germany biogas production is getting somewhat unpopular at the
moment. A lot of the resistance is spreaded by citizens who don't
want to have a biogas plant in the neighborhood (this can be
understood if this may be a plant of x MW). The use of social media
networks, web sites and discussion groups makes it easy to spread
these thoughts widely. It's easy to link to this youtube video
showing cattle dying and using the word "biogas" in the same
sentence, but:<br>
<br>
* do you see a biogas plant in this video?<br>
* do you hear the word biogas in this video?<br>
* the statement at the end is, that they do not exactly know the
cause<br>
* they say "cattle farms" are effected, not "biogas farms"<br>
<br>
* => so this may be a problem of intense cattle farming in
general than a special biogas problem in particular?<br>
<br>
We all had this in the german discussion board before, perhaps you
may get some more information here, e.g.:<br>
<a class="moz-txt-link-freetext" href="http://www.schlattmann.de/forum/viewtopic.php?t=2178">http://www.schlattmann.de/forum/viewtopic.php?t=2178</a><br>
There are also some other links to this topic in this thread.<br>
<br>
We also had some food<=>biogas discussions, but this may
depend on the area/country if food is rare. In Germany for example
this is not the case.<br>
<br>
For organic enrichment in soils, someone may also use
intertillage/catch crops?<br>
<br>
<br>
I think I will post these lines also to my english language board
for some additional discussion/thoughts.<br>

<br>
I have received this from a few people now...it is clearly
circulating widely. I have plenty of comments regarding the soil
aspects, and certainly some of the AD sludge contents from
industrial or black water plants is a bit beyond my expertise, but
I would certainly appreciate some comments from this group,
especially any Germans that can comment on the YouTube part. This
guy clearly is now against biogas, and it would make sense to have
some good responses to this type of thing. <br>

</span><span style="font-family: Georgia; font-size: 16px;

biogas there are at least two extremely severe problems:</span><span

line-height: 19px;"><br style="line-height: 1.22em;">
</span><span style="font-family: Georgia; font-size: 16px;
line-height: 19px;">Organic matter that is converted into gas is
no longer availabel to produce humus, so there are reports from
farmers that the soil is getting less and less producticve. Rich
soil may be far more important that the relatively litte amount
of gas. Composting expecially with earthworms and additon of
some charcoal dust (can easily be made from straw, rice husks
instead of the terrible burning) ideally plus stone dust can be
far more beneficial with rising productivity for food and more
biomass and is simple, too. At TUHH we are now working intensely
of also composting urine and mixed excreta stabilised by
lactofermenters together with woody wastes to make more soil as
I want to work with ecolocical agriculture and not do industrial
agriculture with addion of fast fertiliser. Biogas can be a
threat for long term food security and you will have to pay for
the gas with more and more fertiliser demand, less water
reproduction, flooding through compacting soils.</span><span

the highly toxic substance, there are hundreds of farms where
all milk cows are dying and the farmers are ruined, even they
became ill sometimes. The reason are fodder fields that are
fertilised with the sludge from the biogas plants. The very
dangerouos botulinum toxin (misused by people who hate aging by
paralysing nerves in the face thus turning it into a mask, then
called botox) is only showing effect after many month so the
effect is often not related to the cause.</span><span

and have planned and built them, I will not do this anymore

sanitation in areas where the soils are super humus rich already
