**********************************
Sustainable Sanitation Alliance (SuSanA) side event
Monday 22 September - 15:30 - 17:00
Room 1.06
Centro de Congressos de Lisboa - Parca Industrias, Lisboa

Determining system boundaries for climate mitigation in sanitation programmes using an energy footprint perspective

Sanitation systems include the user interface, conveyance, treatment and safe reuse or disposal, the combinations of technologies that can be implemented within a sanitation system and their energy footprint varies greatly from context to context. Therefore a potential to reduce Green House Gas (GHG) in sanitation systems exists. As more climate mitigation programmes are planned the potential that improved sanitation systems offer to reduce energy consumption presents an opportunity to consider the ideal system boundaries and their impact on the energy footprint.

An energy footprint perspective takes into consideration both energy consumption as well as embodied energy. With consideration of the energy footprint alongside more traditional economic analysis, decision makers would have a better perspective to judge investment decisions in sanitation systems that should contribute to climate mitigation. The challenge is where to set the system boundary.

The discussion would look at the challenges of determining the system boundaries and the impact that moving system boundaries have on the energy footprint. The discussion will include questions like; when looking at defining the ideal system boundaries for assessing a wastewater system holistically should embodied energy be considered? What happens to the energy footprint when the system boundary is expanded to take into consideration the impact of reusing wastewater in agriculture? Many more questions will come from your interactive participation in the side event.

Side event format:
15:30 to 15:40
Introduction and setting the scene for the side event - Trevor Surridge (SuSanA secretariat held by GIZ)

15:40 to 15:50
Overview of energy consumption patterns using the Waste Water Treatment Plant as your systems boundary - Catarina Silva (LNEC - National Civil Engineering Laboratory)

15:50 to 15:55
Q & A

15:55 to 16:15
Using an energy footprint perspective to see the impact of moving system boundaries with illustrative cases from India, South Africa and Germany - Stefan Reuter (BORDA)

16:15 to 16:20
Q & A

16:20 to 17:00
Fishbowl discussion - Can an energy footprint perspective help us set better systems boundaries for climate mitigation programmes involving sanitation systems? - All participants

Why you should attend the side event:
  • To learn about and discuss the energy footprint perspective in sanitation systems.
  • To participate in an interactive side event using the fishbowl format to discuss a paradigm shift.
  • Collaborate with your peers on considering new ways of thinking about system boundaries for sanitation systems within the context of climate mitigation programmes.

I am working for Clean Ganga Mission. Having responsibility to
introduce new technology for treatment of waste water with the objective abetment
of pollution in river Ganga and its tributaries. During my work, I find debate
is going on whether we should adopt centralized or decentralized treatment of
waste water. In general practice we adopt centralized way of treatment and many
other issues. I am working in the field from last 28 years handled many
projects with capacity building experience also. I am interested for IWA

Re: Greenhouse gas emissions from sanitation value chain in urban poor settlements (UDDTs versus latrines) - by: muench http://forum.susana.org/forum/categories/56-wg-3-energy-climate/8164-greenhouse-gas-emissions-from-sanitation-value-chain-in-urban-poor-settlements#8654 http://forum.susana.org/forum/categories/56-wg-3-energy-climate/8164-greenhouse-gas-emissions-from-sanitation-value-chain-in-urban-poor-settlements#8654
How has your research progressed by now? I saw on Twitter that Alison mentioned a paper that is coming out soon, does that mean your research has already been concluded?

She said on twitter:
e.g. the @WSUPUK project illustrated the low carbon footprint of ecosan vs a sewered system or even a simple pit latrine #sanitation

@Ostella42 @WSUPUK We're working on a journal paper with the results so it should be in the public domain soon!


Otherwise, I just wanted to make sure you had seen this MSc thesis? (is it any good?) :

susana.org/lang-en/library/library?view=...p;type=2&id=1596

Diafarou Ali, M. (2009). Carbon dioxide and methane emissions from different wastewater treatment scenarios. UNESCO-IHE Institute for Water Education, Delft, the Netherlands. MSc Thesis (MWI/SE 2009/39).

And I also followed the lead that Christoph Platzer gave us in his post above and searched the archive of the old Ecosanres Discussion Group for the topic of Greenhouse Gas Emissions (groups.yahoo.com/neo/groups/ecosanres/info) (this group was closed when the forum started, but was active in the years 2002 to 2012)

I found various things there in the archive but the only thing really of relevance here, I think, is a post by Chris Canaday (our featured user of this month!) from 2009 where he wrote:

++++++++++++++

Dear David,

The message you mention may have been one of mine (which Ian kindly found and resent), in which I mention the conceptual reasons that EcoSan reduces Greenhouse Gas (GHG) Emissions and encourage someone to work out precise numbers.

I would like to take this opportunity to complete a bit the list of reasons that UDDT toilets contribute to controlling the Greenhouse Effect:
(a) reduced methane emission by avoiding anaerobic fermentation of feces in water,
(b) increased CO2 sequestration via fertilization of plants and trees,
(c) increased carbon sequestration into the soil via integration of organic matter,
(d) reduced use and transport of chemical fertilizers (another source of GHGs),
(e) reduced use of petroleum for pumping and treating water.
(f) reduced demand for cement for building large sewers (since cement production is a big source of CO2).

I am convinced that the UDDT of one of the simplest and least painful ways we can reduce our "Carbon Footprint" and our "Ecological Footprint" in general ... and that this will be very evident to all interested parties once the numbers are worked out, especially taking into account all of these 6 factors. Most other options involve walking more, colder houses, not consuming whatever we like, etc., which impinge more on people's lifestyles ... but the psychological barrier of the UDDT has to be jumped.

There is a mention of this on page 126 of Ecological Sanitation (2004. Winblad et al.) It would be great if the corresponding bibliographic citations (and more recent articles) were available on-line.

UDDT advantages in adapting to Global Climate Disruption are very clear: (a) less demand for precious water and (b)improved water-holding capacity of soils.

For these reasons, we should be able to access various Global Climate funds for building UDDTs. One way would be to set up, or work with existing, villages in desertified areas and build UDDTs (thus reducing methane emissions of people who had previously been using flush toilets) and use the greywater and EcoSan fertilizers to cultivate fruit trees in the desert around the village (thus sequestering carbon into tree trunks and soils) ... and creating livelihoods and economies where previously none existed. Maybe we can collectively spark something.

One student member of this forum, Diafarou MOUMOUNI, responded that he is doing his master's thesis on a comparison GHG emissions from various wastewater treatment options, including the (non-wastewater-producing) UDDT. We can all look forward to seeing his results as they come out.

Best wishes from South America,
Chris Canaday

Hope this helps and I hope you will give us an update on your research?

you might get some -measured, quantified- results from a French NGO called "Solidarités"; this NGO was a project partner of me resp. my employer and built an operated covered latrines in a Rohingya refugee camp in south-eastern Bangladesh. They collected the gas and used it for fuel in the camp's kitchen with some success in 2011/2012. They might be able to give you some of their quantifications about volumes and quality of the gas.

I have the impression we already had a specific exchange about greenhouse gas emissions of latrines and UDDT trying to calculate both, one comparing to the other. This was about 3-4 years ago, maybe still in Ecosanres. I tried to remember but I could not find it quickly so I just do this reminder to the others.

If you can, please try to do at least some quick-and-dirty gas measurement, since the real world conditions can be complicated and unpredictable ... and a priori assumptions could lead the wrong way.

If in fact no one has done so, someone urgently needs to cap a pit latrine and measure the gases emitted within.

Here is some support for my assertion that soil microbes can consume Greenhouse Gases:

Many thanks for your reply and interest in our work!

Yes, you understood our approach correctly and this is the main limitation of all our estimations (rather than calculations) as all of them are based on other peoples work. And still many things have never been analysed and are based upon assumptions (no one has covered a pit latrine and measured the gas emissions for example). In the recommendations we will spend some time on future research possibilities to fill these gaps but unfortunately we do neither have the time nor the finances to do it ourselves.

To your comments:

1) Yes, we meant UDDT while speaking of Ecosan and have changed that.

2) We will most likely not go into the intentionally intended depth of each system as to include different cover materials as the project is much more complex than we thought and we are running out of time – but for future work a very interesting point!

3) As the focus is on informal settlement in urban poor we did not include this option but again a very interesting one for future work.

4) We do not have a link in form of an URL to clean team chemicals but did analyse them in depth and include them into our spread-sheet as they play an important role and are questionable from my personal point of view (Lars Pelzer).

5) Yes, taking the LCA (Life Cycle Assessment) approach we do include production, transport and operation of different materials.

My best,

Since we are considering high density urban poor settlements we’d like to include a central composting station for the UDDT (previously named Ecosan but thanks to Chris Canaday we’ve changed that).
Does anyone have construction specifications for a composting centre in Sub Saharan Africa? We’re assuming that it’ll be a paved ground and manual turning of compost as easiest form.

Congratulations on undertaking such important work.

Do I understand correctly that you will be estimating Greenhouse Gas Emissions via published data and theoretical calculations? Given the complexity of the processes involved, it would be excellent for someone to measure these emissions empirically.

A few comments on your attached table:

1) EcoSan is a broad category of techniques to recycle nutrients and not treat excrement as waste. I believe you refer to the UDDT (Urine-diverting Dry Toilet).

2) Within the UDDT category, it would useful to analyze different cover materials, including sawdust and wood ash (which are commonly used), but also more biologically active substances, such as rich, organic soil (including compost from kitchen waste or recycled UDDT cover material after storage and/or treatment). Please take into account the potential for soil microbes to consume these gases before they are emitted into the air.

3) What would be the emissions from WC + Sub-surface-flow Constructed Wetland?

4) Please give us a link to a description of the CleanTeam Technique and the chemicals used. www.cleanteamtoilets.com/our-model/ does not give any useful detail.

5) Please include in your calculations the GHGs emitted during the production and operation of the vehicles used to transport materials.

Good luck with your work. I look forward to seeing the results.
