Terra Preta Sanitation...
-------------------------------
is a systemic approach to link sanitation and agriculture to protect soil
fertility and water ressources. Instead of polluting fresh water with human
excreta and urine they are used to create Terra Preta soil. Terra Preta is
a highly fertile black soil made by composting biowastes in addition of
charcoal and faeces which are pre-treated by lactic acid fermentation. It
was invented by an ancient Indio civilisation in the Amazon forest and is
still fertile after hundreds of years when it was discovered about 30 years
ago.
This video series...
-------------------------------
gives an overview about Terra Preta Sanitation (TPS) which links different
technologies and other related topics from ecological sanitation research.
It is a produced as a student project by Andreas Swensson at the Institute
of Wastewater Management and Water Protection at Hamburg University of
Technology under the supervision of Prof.-Dr. Ralf Otterpohl. It is meant
to be used to promote and inform about TPS, to network groups and project
all over the world and for educational purposes. You find an introduction
of all in video "14. who is who".
