  8 Innovative & Eco-Friendly Toilets That Can Help India Overcome Its Sanitation Woes admin 2017-09-09 1644  

It''s 2017 and India still faces a massive problem with toilets. One billion people worldwide still practice “open defecation.” India alone has an estimated 600 million people defecating openly, according to a study by the United Nations. 

In a blog post titled, “India Is Winning Its War on Human Waste,” Bill Gates recently lauded Prime Minister Narendra Modi''s ''Clean India'' initiative which  includes ending open defecation nationwide by 2019, installing 75 million toilets throughout the country.

However, India is far from hitting this magnanimous target. The ground reality of sanitation still looks bleak, people are still using the floodplains as a toilet and defecating in the open, is surprisingly, more of a choice than compulsion. 

Toilets provided by the government, are more often than not filthy and in some cases even used as storage facility in rural areas.

There is still an urgent need to sensitize thousands about the dangers of defecating in the open and the need of the hour is to come up with more innovative strategies. 

Perhaps, these inexpensive alternative to traditional waste disposal could be key in solving India''s overwhelming sanitation woes.

1. SafiChoo Toilet

Made of plastic, the toilet is designed for sitting or squatting. According to their website, SafiChoo is an inexpensive mobile toilet intended reduce oral-faecal contamination and the spread of water, sanitation, and hygiene related diseases.

"The toilet also separates waste in two ways. First, the urine is diverted in the front cavity and is infiltrated into the ground to act as fertilizer for the soil. The faeces is deposited in the back cavity and goes through a series of filters that separates solid waste, pathogenic waste such as vomit and diarrhea, and cleansing water."

2. Bio-digester Toilet

The bio-digester is a simple, low-cost technology for treating human waste and providing safe sanitation facility. The technology was developed by the Defence Research and Development Organisation (DRDO), to meet the sanitation requirements of soldiers serving in the high altitudes of Ladakh and Siachen, reports the Hindu.

The Bio-digester toilets are designed to convert human waste into gases and manure. It uses psychrotrophic bacteria like Clostridium and Methanosarcina to break down human excreta into usable water and gas.

3. Ecosan Toilet

In Ecosan toilets, there is no need to flush and the urine and faecal matter is utilised as valuable urea and manure. Which means sewage and manual scavenging will never be a problem. It is built above the ground level using conventional bricks or hollow blocks. It has two chambers – the urine, faeces and cleansing water go into separate holes.

4. Tent Toilet

Another brilliant way to tackle the open defecation scourge. The portable toilet can be set up anywhere and the waste is collected in a biodegradable bag that contains ‘ChemiSan,’ a material that helps to deodorize and decompose the waste.

5. Unmanned self-cleaning e-Toilet

Eram Scientific launched e-Lite 14, the world’s cheapest solar-powered unmanned e-toilet for schools, in October, 2014. The toilets are programmed to flush 1.5 litres of water after three minutes of usage. It can also be programmed to clean the platform with a complete wash-down after every five or 10 persons use the toilet.

The toilet is made of mild steel, and he unit is self-sustaining and equipped with internet connectivity for remote access.

6. Two Pit Compost Toilet

This flush compost toilet is eco-friendly, technically appropriate, and affordable. The toilet can easily be constructed by local labour and materials. According to this website, the capacity of each pit is normally designed for 3 years’ usage. Both pits are used alternately. When one pit is full, the incoming excreta is diverted into the second pit.

 7. The Nano Membrance Toilet

The nano-membrane toilet removes the water from human waste and leaves solids that can be used as fuel or fertiliser. According to the Guardian, instead of a flush, the toilet uses a scraper mechanism that sends the waste from the toilet bowl into a collection tank and the solids collect at the bottom as sediment and where the liquid waste is filtered.

 8. The Nano Membrance Toilet

When it comes to sustainable and affordable sanitation, these Bamboo toilets perfectly fit the bill. The structures are built with bamboo and are stronger comparable to steel. Bamboo toilets are a huge hit in Nagaland, the initiative to set up the eco-friendly toilet was organised by Nagaland Bamboo Development Agency (NBDA) and South Asia Bamboo Foundation.
