SuperForest Heroes! – Dr. Bindeshwar Pathak & Sulabh International!

Gooood Morning SuperForest,

This great man is Dr. Bindeshwar Pathak. He founded and runs Sulabh International.

Sulabh International is a social service organization in India that builds toilet complexes. Three quarters of people living in India are without access to toilets, so these complexes do wonders for the local communities. The Sulabh complexes free people from the indignity of having to poo out in public, as well as keeping the environment free of human waste. Women who had to “hold it” during the day or risk their modesty now have a place to go, helping them avoid a number of health issues. The Sulabh complex provides toilets, showers, and rooms for nursing mothers, all for the equivalent of two cents. The toilet/sanitation complexes also frees the former scavenger class (predominantly women) whose job it had been to go and manually pick up the humanure.

Here are some numbers:

“More than 7,500 Sulabh public toilets constructed and maintained throughout the country.
Each day, over 10 million people use the 1.2 million individual toilets and more than 7500 public toilets constructed and maintained by Sulabh.
Number of scavengers liberated: More than 120,000 scavengers have been liberated from scavenging and rehabilitated after proper counseling and vocational training.
Towns made Scavenging-free: 240″

With the money generated from the toilets, Sulabh runs a chain of schools dedicated to educating the former scavengers who job it used to be to go and clean up the poo. These lucky folks receive the education free of charge.

“(Dr. Pathak) has made innovative use of biogas creation by linking Sulabh toilets to fermentation plants, he had designed over three decades ago and which are now becoming a byword for sanitation in developing countries all over the world. One of the distinctive feature of Pathak’s project lies in the fact that besides producing odour-free bio-gas, it also releases clean water rich in phosphorus and other ingredients which are important constituents of organic manure. His sanitation movement ensures cleanliness and prevents greenhouse gas emission.”

His initial invention was the dual pit composting latrine. A low water-use system that can serve hundreds of people, it turns humanure into biogas for lights and power generation, and in the end renders the manure inert and useful for agriculture.

This simple system is now in service all across India, serving millions of people, cleaning the environment and freeing people from manual scavenging. The Sulabh complexes are a massive win for the people of India.

And I’m very much hoping that they could be a win for the United States as well. A clean, composting latrine facility that uses very little water, creates fertilizer and biogas, cleans the water, and gives people a comfortable place to do their thing, all while generating income is a great idea. Saves water, runs clean, generates energy, makes people happy, makes money.

SuperForest is beginning a partnership with Dr. Pathak and Sulabh to help communicate their incredible work within the US and wherever SuperForesters are reading this. In return, Dr. Pathak has agreed to an interview (hopefully series of interviews), as well as sharing the details of his technology with us, and sharing with SuperForest the stories of his works and triumphs.

Dr. Pathak, you and your organization are an inspiration to me and Team SuperForest. Thank you for the hundreds of thousands of lives that you have improved with your selflessness and generosity. You have worked to fulfill Ghandi’s wish to free the scavenging class from the horrors of manual refuse cleaning, and worked to rehabilitate and educate those who your work has freed. Thank you for your dedication to creating happiness.

We look forward to working with you and Sulabh for many years.

Treehugger: 5 Ways to Make Energy with Excrement


Treehugger’s got a great round-up post about projects around the world that are using manure to produce biogas. Yes, the very same biogas that you can use to fuel your car or heat your home.

How does it work?

Take a whole lot of poo. Feed it to eensy tiny bacteria who will eat the poo and exhale biogas. Capture and condense the biogas and you’re rolling.

Got it?

Here’s the article: Treehugger – 5 Ways to Make Energy from Excrement.

Or, to save you a click:

“Perhaps its because of our monkey roots—their lack of inhibition when it comes to handling their own filth must be lurking in us somewhere—that many of us find poo jokes and toilet humor so funny even as we, cough, mature. While excrement may elicit laughs, snickers and giggles from some, it really is serious business when it comes to energy.

For those that don’t know, the way all of these projects work is they take the human or animal waste and convert it into biogas via anaerobic digestion. Then the gas is either fed into the exisiting natural gas distribution system, converted into electricity, or used directly as an energy source.

It seems like we’ve heard about enough new human or animal waste to energy projects or studies lately that a roundup seems in order. From the past seven months, in reverse order:

Vancouver-area Sewage Treatment Plant to Produce Biogas

At a cost of $1.1 million the Lions Gate Wastewater Treatment Plant Biomethane Project will create biogas from human waste which will be fed into the area’s existing natural gas distribution system. Expected to be operational in July 2009, this pilot project will provide enough energy for 100 homes and will be the first human waste-to-energy project in British Columbia.

Cow Manure Could Generate 3% of US Electric Demand

A study done at the University of Texas, Austin estimates that the livestock industry in the United States produces 1 billion tonnes of manure annually. If this were used to generate biogas and then electricity, up to 3% of total US electric demand could be met.

Making Power From Poop

A 750 cow dairy farm in Ontario has received $5-million in funding to build what will be the province’s largest farm-biogas installation. The project will have a capacity of about 1.3 megawatts, or enough to power about 800 typical Ontario homes.

Cow Poop -> Electricity

The Vintage Dairy Biogas Project will produce enough biogas to power 1200 homes a day in California. The biogas produced will be fed into the natural gas distribution system and used in a PG&E power plant in Northern California.

Human Poop and Urine Used in Uganda for Biogas

Leading off the year’s waste-to-energy news was a piece on how Heiger International Uganda is working with several partners to build biogas plants, using human excrement and a mixture of banana peels, algae, water hyacinth and chicken manure as the feedstock. The biogas isn’t being feed into a grid like the projects in Canada and the United States, above, but is being used for cooking, lighting and in various types of engines.”
