Subject: Re: [LittleHouses] "Bioconversion of Putrescent Wastes"
Thank you for an excellent article!
I'd like to know what Dr. Olivier et al might have
done
with large commercial and industrial use of these
units.
How do they work with medical wastes such as hospitals
and nursing homes?
How have they worked at malls,theme parks,concert or
sports arenas,livestock areas and the like?
My hometown hosts horse shows year round.
We get quite a few biting flies and mosquitoes,tons
of food waste and a large amount of used stable
dressing.
It sounds as if these units could be incorporated into
the general design for a nominal cost and decrease
waste disposal,pests,disease,odor,etc. a great deal.
Other measures of reducing waste and recycling could
be implemented much more easily to manage the rest of
the impact of having so many people and animals in
attendance for such extensive periods.
This wouldn't even count the synergy of incorporating
traditional composting and using the flies and the
food residue to grow plants and feed fish and poultry.
This would be an 'invisible',toxin-free way of making
our most inefficient and unpleasant areas a boon
rather
than a bane to our environment.
