toilet signs & gender segmentation

Speaking about sanitation, most people probably just think of toilets and how to improve on that. And while we rather think about the involved process engineering (aka the technical side) associated with this daily business, the toilet, it’s availability and cleanliness is what is seen by the majority.

It is against this background that I would like to forward you to this interesting post on gender and toilets (also here because of the additional comments) as there’s still a complete world full of such unsolved gender issues.

Fortunately, or at least that’s what I think, any debate on toilets (~sanitation, ~hygiene, ~privacy, ~comfort, etc.) is good & a way forward into the right direction. So if it takes a gender issue like the rather unfortunate (or not?) seperation into women’s and men’s washrooms for people to return talking about toilets, then we’re one step closer to an improved sanitation. Do you agree?

water supply & sanitation map in Africa

During a recent trip to the GTZ office of the “sustainable sanitation – ecosan” program in Eschborn, Germany, I stumbled upon the following interesting map that display various international NGOs working on water supply & sanitation issues in Africa.

The Peepoo bag system – top or flop?

Another blog post on the Peepoo bag system – the biodegradable toilet bag system for use in places where there are no toilets available. A single-use, self-sanitizing, biodegradble system that turns into fertilizer after use.

A follow-up to another blog post from December 2008 from my private blog on the same subject (“Flying Toilets 2.0″), if you will, because a lot has happened since then and I wanted to find an open space to note down all the pros & cons, the advantages and disadvantages of such a bag system. You are of course invited to share your opinion on these bags and leave a comment!

I also think that there’s no single truth on this subject – something I’ve learned from blogging on Afrigadget.com where we often cover gadgets that may appear to be very simple, but also still do the job.

Systems and technologies do not have to be perfect in order to work, and what is sponsored by dev aid orgs and private individuals may not necessarily be appreciated by the recipients (who will accept it anyways when it comes for free). Rather, a lot of different technologies may coexist – may also compete with each other – but to condemn a system just because it isn’t 100% sustainable isn’t too fair, I think.

“Eco-friendly toilets for Kenya slum” (Al Jazeera story)

In my books, a system that tries to close the loops on nutrients and is accepted by its users, is of much greater value than a traditional flush toilet. But that’s just me. And again, it’s not just a matter of provding toilets and basic hygiene standards, but instead so much more that can not be changed in one go. Urbanisation may be one core problem, or the question of land ownership which often results in slum dwellers having a greater interest in getting their hands on a TV set + VCR instead of a clean & secure toilet. The list of reasons is probably endless, and the following list also can not include all criticism and truth, so please free to add your own thoughts about the Peepoo system. Thank you!

Most of the following points where taken from the EcoSanRes Yahoo! group where the subject has been discussed for quite some time now. There also is an interesting short report with results of a medium-scale trial of these bags in Bangladesh (PDF; 1.7 MB) which was published in GTZ ecosan newsletter no. 34 in September 2009.

pros:

• good for temporary / emergency situations
• initial target group is used to conventional “Flying Toilets 1.0″
• may be used at home & at nights
• is mobile
• alternative to dirty (public) latrines
• allows for a sanitization within a relatively short time and prevents (stronger) odours
• relatively low costs
• does not require water (= there are no sustainable water options available + this is a dry toilet system)
• no permanent infrastructure like septic tanks or even sewerage required = no maintenance costs
• use as fertilizer in urban farming projects (like this one in Kibera, Nairobi, Kenya)

cons:

• no permanent solution
• not 100% sustainable
• not free (costs vs. convenience, but also future value from fertilizer which could be set off against the price of these bags?)
• bags may be too thin and too small for some users
• higher risk of users getting in touch with their faeces (=> hygiene standards)
• difficulties in using the bag when defecation is accompanied by urination (for women)
• ammonia gas may leak from torn bags & will become an immediate public health problem // oduor problems when many filled Peepoo bags are stored together during collection and transport
• the bags should be more durable, stay intact and gas tight long enough for the ammonia to have time to kill off all the possible pathogens (thx, Håkan!)
• the composting part could still be improved, e.g. store them in tight containers for maximum ammonia retention & then plow them down into the soil before the cropping season (thx, Håkan!)
• may degrade too slowly (bioplastic bags used in many modern households today for compost are often removed on compost plants because their plastic requires a temperature of about 60°C or higher which may not always be achieved within the given time frame)
• bag system is patented => how do you prevent fake (= non biodegradble) bags from being sold on the market?
• requires a shielded space / privacy => question of dignity (where do you defecate? and where have the Flying Toilets 1.0 users previously defecated?)
• requires a handling & reuse concept, preferably in the vicinity, but this actually applies to almost all waste stream
• risk of losing political responsibility for a better sanitation concept

According to the BASF Sustainability Newsletter 5/2009 – manufacturers of the bag material – the “bags (are) made of BASF’s biodegradable plastic Ecovio. The plastic Ecovio consists of Ecoflex and of polylacticacid (PLA), which is obtained from corn. Ecoflexis a petrochemical-based polyester and is completely biodegradable. Eco-flex makes the bag flexible, tear-resistant, waterproof and suitable for printing”. (Thx, HPM!)

Also, what works in Africa will also work anywhere…? That’s one of our slogans on AfriGadget, but the reality of course is that each community has its own habits. Here’s another blog post by someone who tried to brake it down for India (with additional comments by Elisabeth von Münch, GTZ sustainable sanitation & ecosan team leader).

I am actually quite happy about the good media coverage that Peepoo(ple) has received lately. From a scientific perspective, things may not always be that clear and there’s always room for constructive criticism. From a blogger, user, km4dev and watsan worker perspective though, any media coverage for sanitation in urban slums is highly appreciated and still needed (one of the reasons for this blog on sanitation).

What I really like about the Peepoo system is that it doesn’t require much behavioural change and adds value to something that is often only regarded as waste. Maybe it takes such an extreme low tech approach to get the message of “closing the loops on nutrients” across.

And you? What do you like or dislike about these bags? Please feel free to share your comments with us. Asante sana!

new publication: guidance manual for Water, Sanitation & Hygiene in Schools

Water, sanitation and hygiene (WASH) in schools programmes are globally recognised as essential to promoting children’s right to health. WASH in schools influences a generational change in health promotion behaviour and attitudes. If schoolchildren have access to clean and appropriate toilets, functioning handwashing facilities with soap, sufficient and safe drinking water and have developed adequate hygiene skills, they are more likely to be healthier and to positively influence hygiene practices among family members and the wider community.

This book is meant for managers and trainers involved in water, sanitation and hygiene programmes in schools, whether operating at state, district or block level. It provides information on a number of essential topics related to WASH in schools and contains relevant activity sheets.

World Water Day 2010

Going by Social Media standards, World Water Day 2010 has been a full success. “World Water Day” is a trending topic on Twitter, thousands of people gathered online and offline to join the world’s largest toilet queue and various other NGOs as well as GOs are using Facebook & their blogs to highlight the importance of such an international day.

Social media, online stuff – where’s the real action you ask?

Well, here it is:

Enjoy!

Sanitation, solid waste and climate change

According to IPCC, the waste sector (wastewater + solid waste management) accounts for 2.7% of global Greenhouse gas (GHG) emissions. However, this does not reflect the whole truth as IPCC calculatations only take into account end-of-pipe waste management strategies neglecting the potencial of reducing, re-using or recycling waste (which applies mainly for solid waste management but also for innovative sanitation tecnologies such as anaerobic digestion and ecosan approaches).

For this reason it is important to investigate the contribution of the waste sector to GHG emissions and integrate the mitigation potential in waste management. Besides many interesting papers presented at conferences worldwide about the importance of an integrated organic waste and wastewater management and its influence on climate change, GHG emissions and the potential of CDM-projects in this field, instruments are needed that show the potential of emission reduction in the waste sector.

One of those instruments available is the recently published “Tool for calculating Greenhouse gases in solid waste management (SWM-GHG Calculator)“. The SWM-GHG Calculator was developed by IFEU Institute and sponsored by KfW Development Bank in cooperation with GTZ. It is based on Excel as a common spreadsheet application and accompanied by a user manual. By help of the calculator waste management strategies can be compared by calculating the GHG emissions of different waste fractions over their whole life cycle following the Life Cycle Assessment (LCA) approach. It does however not provide an in-depth LCA and is not suited for calculating the anticipated quantity of certified emission reductions in the CDM-framework.

More tools that demonstrate the relationship between sanitation and climate change are definitely needed.

new WSP publication: Financing On-Site Sanitation for the Poor

New publication by the Water and Sanitation Program (WSP): “Financing On-Site Sanitation for the Poor - A Six Country Comparative Review and Analysis” (PDF; 2.4 MB)

Public investments of varying forms enable an absolute increase in the number of poor people gaining access to sanitation, varying from 20 percent to 70 percent, according to a study of six cases in Bangladesh, Ecuador, India, Mozambique, Sénégal, and Vietnam by the World Bank-administered Water and Sanitation Program (WSP).

This publication seeks to identify the best-performing approaches and the relevant factors and issues to consider in designing a sanitation financing strategy. The report offers guidance to sector professionals developing on-site sanitation projects and programs, which play the leading role in providing access to sanitation.

The Water and Sanitation Program is a multi-donor partnership administered by the World Bank to support poor people in obtaining affordable, safe, and sustainable access to water and sanitation services.
