Terra Preta Sanitation project in Philippines

Dr Elmer V Sayre has provided a biochar related project report from the Philippines. This has been sent to IBI for the January newsletter. A summary of this report is provided below... the full report is available on request. The Ecosan project ( is also linked to this work.

Transforming Human Waste and Other Organic Matter into Highly Fertile Soil via Terra Preta Sanitation and Biochar: The WAND Foundation Experience

........."Our Terra Preta – Biochar mix include sawdust, urine, animal manure, feces, charcoal and the bacteria Bacillus subtilis.  The feces we get from the number of urine diverting, dehydration (ecosan) toilets that we established among local cooperators in 3 municipalities in Misamis Oriental and in Dipolog City. The charcoal we are using are partially burned rice chaff from rice mills in Dipolog City as well as charcoal from copra production." ..........

........... "So far our results are encouraging. Last November 2010, we started an experiment using our terra preta – biochar mix to coconuts, bananas and rice. We also provided the mix to our farmer-cooperators as pilot initiatives with the view of expanding this later on."

E-copies of my book on experiences in promoting ecological sanitation is available upon request.
