Hi All, <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>

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 style="font-family: Georgia; font-size: 16px; line-height: 19px;"><br style="line-height: 1.22em;">

growing rapidly under anaerobic conditions producing 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 style="font-family: Georgia; font-size: 16px; line-height: 19px;"><br style="line-height: 1.22em;">

used to be very positive towards biogas and have planned and built
them, I will not do this anymore except for some industrial wastewaters.
Maybe also for sanitation in areas where the soils are super humus rich
already and botulism can be avoided safely.</span><span style="font-family: Georgia; font-size: 16px; line-height: 19px;"><br style="line-height: 1.22em;">
