Ecological sanitation for the base of the pyramid (Closing the loop between sanitation & agriculture in Mindanao, the Philippines using lactic fermentation)

2011 - 2012 • WAND (Water, Agroforestry, Nutrition and Development) Foundation, Inc.

Purpose

Exploring the viability of low-cost dry toilets and the use of human waste in small-scale agri-silviculture including crop trials; testing secondary treatment with vermi-composting and researching odour minimization.

Activities

We were one of the Grand Challenges Explorations Round 7 (GCE7) winners and received a US$100,000 grant from the Bill & Melinda Gates Foundation for to work on the project “Ecological Sanitation for the Base of the Pyramid”.
This project allowed us continuing our research on the high-grade production of human-waste-mixed organic fertiliser mentioned in my earlier post. But we did not only develop SaniFert, but carried out other activities and I would like to share here some experiences and results.

During 1 year (March 2011 – October 2012), we explored the viability of low-cost dry toilets and the use of human waste in small-scale agri-silviculture by designing and installing dry toilets, developing a process for high-grade fertiliser production from human faeces, conducting crop trials, testing secondary treatment with vermi-composting, researching odour minimization, and mainstreaming ecological sanitation in local micro-finance institutions.

Countries of activity

Location of main activity

Objectives

- To address the sanitation needs of the “base of the pyramid” (this means adopt the design, the double-vault ecosan toilets are too expensive in the Philippines),
- Provide not only access to sanitation; prevent the spread of diseases, and contamination, but also to make available much-needed fertiliser especially for small-scale farmers.

Further information

At present we are using our fertilizer product to reforest a 300 hectares mountain area in Initao, Misamis Oriental. So far the results are promising. This is part of our project is funded by the German Doctors for Developing Countries and the German Federal Ministry of Economic Cooperation and Development.
Furthermore, our current activities include:
- Continue designing versatile, robust and affordable ecosan toilets and to conduct comparison for serviced and non-serviced systems
- Expand ecosan re-use research for small-scale agriculture and agro-forestry
- Pilot a village-operated mini-laboratory for Ascaris detection as well as lactic acid bacteria and indigenous micro-organism production
- Start in-depth human waste-based organic fertilizer and feces cover formulation efficacy research
- Expand ecosan marketing to include other financing institutions such as cooperatives and commercial banks
- Conduct a more comprehensive market study, and
- Pilot the creation of “ecosan marketing and production hubs” to promote and market dry toilets.

The WAND Foundation provides social development programmes with an emphasis on biodiversity, the environmental and agricultural sectors, and rural entrepreneurship for local communities in the Philippines. In collaboration with Science for Humanity, WAND aims to explore the use of treated household waste as fertilizer for crops and vegetation. They also joined the Global Giving Challenge. There the "Ecological Sanitation and Food Security Project" is running. They target 300 marginalized families. Providing them with arborloo toilets and "pump-priming" livelihood resources will improve their economic self-sufficiency and ensure their living dignified lives rather than living like animals.
