○Research Subject and Objectives

Problem, background, and objectives

Globalenvironmental problem discussed in the project: 

The word “Sanitation”is used for showing the provision of facilities and services for safe disposaland resources recovery of human urine, faeces and wastewater in the project.  Sanitation is essential for promoting health, reventing environment pollution, conserving ecosystem, and recovering andrecycling resources. Therefore,it can be said that sanitation is closely related to such current global issuesas poverty, urban slum, conservation of ecosystem, and resources management. Indeveloping world, population is growing rapidly especially in urban slums andthey have still high under 5 mortality and poverty issues (see SupplementFig.0-1). It also reportedthat 2.4 billion people are still using unimproved sanitation facilities,including 946 million people who are still practicing open defecation in 2015(UN, 2015). On theother hand, depopulation and aging are progressing especially in rural area ofdeveloped world (see Supplement Fig.0-2), and the financial capability of municipality which is a management agency of sanitation system isbecoming weaker and weaker.

Keyquestion in the project:  

Namely, the question, “How can wehandle the waste from 10 billion people in future” and “how can we achieve water and sanitation target in SDGs?” are a global environmental problem tobe solved.

Workinghypothesis of the research: 

Hypothesis-1: Current sanitation issues are causedby the dissociation between the value which is provided by the sanitationsystem and the values of the individual people and/or the community of thepeople.

Hypothesis -2: Sanitation technologies can’t work well without support system. The mismatchbetween prerequisites of technologies and local characteristics makessanitation issues more complicated.

Keyconcept - Sanitation Value chain:  

 The project is proposing Sanitation Value Chain,which has the following basic policies: 1) Put values of people and community inthe centre of discussion, and prepare sanitation system to drive this valuechain; 2) Design the sanitation system by focusing on direct incentive forindividual users and community; 3) Recognize a sanitation system as anintegrated system with social and technical units; 4) Design the sanitationsystem by making a good matching between social characteristics andprerequisites of technologies.

Why Value Chain? :

We are strongly thinking that 1) Planning and installation of infrastructures such as sanitation system isnothing but planning and installing value chain as shown in Supplement Fig.0-3; and 2) Because of weakening of municipalities, the prerequisites of current managementmodel for water and sanitation system will be no longer satisfied in future.

 

b) Methodology

Four  research topics to achieve the goal(Supplement Fig.5-1):

 In Topic -1(Life and Sanitation), field and literature surveys areperformed 1)for analyzing values and Happiness of people; 2)for understanding normto human excreta of current situation as well as historical change; 3)forre-evaluating the value of sanitation system; 4)for analyzing the mismatchbetween prerequisites of sanitation technologies and regional specificcharacteristics of human and community by gathering failed cases; 5)forunderstanding historical change of sanitation system in target areas; and 6)for matching thevalues of people, community and value provided by sanitation system. 

In Topic -2 (Technology), four research activities are planned: 

1)summarizing prerequisites of sanitation technologies; 2)re-evaluatingthe value of sanitation system; 3) analysing mismatch between prerequisites of sanitationtechnologies and regional specific characteristics of human and community bygathering failed cases; 4) developing required technologies. In Topic-3 (Co-creationof sanitation value chain), the following three steps will be adapted:1) identifying stake holders andunderstanding the structure of values of people and community by field survey;2) analyzing hierarchy and structure of stakeholders’value chain and evaluating their mutual affinity;3) developing the co-creation process.  InTopic 4(TD-visualization), main activity is to develop visualizationmethods of our concept and research results by using various media and techniques.We are strongly recognizing the importance of the visual images in TD approach.

Field study: 

The projectperforms the field study at 1) the rural area in Ishikari River Basin; 2) therural and urban area in Burkina Faso; 3) the urban slum in Indonesia; and 4)the urban slum in Zambia.

 

c) Goals and Expected results

Thegoals of this research project are to: 1) propose the concept of SanitationValue Chain as relevant to both developing and developed countries; 2) design severalpilot studies demonstrating the significance of societal, academic, andprofessional involvement in the co-creation of this value chain; and 3)contribute to the establishment of a new interdisciplinary academic foundationregarding on sanitation. The examples of the sanitation valuechain will be demonstrated and co-created at pilot study sites.

 

d) Project organization and membership

For projectmanagement, coordination group are organized. Four research teams are alsoorganized as shown in Fig.8-1 (a) Project Organization and (b)Structure Matrix.

 

e) Current status of research on resource oriented sanitation

Research groups in Switzerland,Germany, Sweden, Norway and Finland are studying resource recovery typesanitation. Three specialist groups of the International Water Association (Specialistgroup on Small Water and Wastewater Systems, Resources Oriented Sanitation andTerra Preta Sanitation & Decentralized Wastewater System in IWA) jointlyheld an international conference (S2SMALL International IWA conference onsustainable solutions for small water and wastewater treatment systems) in October,2017. The sessions of the meeting are as follows: Aerobic Process; GreywaterTreatment; Wetlands; Small wastewater treatment; Onsite Sanitation System;Phosphorous and Nitrogen treatment and recovery) . Also, the topics of the 6thDry Toilet conference to be held  nextyear are as follows: research on safe use of excreta and/or urine; social andcultural aspects of sustainable sanitation; sanitation and nutrient recyclingin business; cross-organizational cooperation and co-creation; hi- and low-techsolutions in urban/rural environment; ecosan meets water-food-energy nexus;promoting sustainable sanitation and nutrient recycling among differentstakeholders; community engagement. The project leader is contributing to thisdry toilet conference as a member of scientific committee. The four researchtopic performed in the project  can makea big contribution to world research on sanitation.

 

Program 3 Goal:                         

Our “lifeworlds” are composed of the physical spaces andsocio-cultural spheres of our everyday lives. They are continually reproduced,reimagined, and evolving through an interactive and reflexive relationship withsociety, culture, and nature. Program 3 proposes research aimed at illuminatingreciprocal linkages between diverse rural and urban lifeworlds and contributingto the solution of sustainability problems by working with various societalpartners such as governments, companies, and citizen groups. Special emphasisis placed on envisioning sustainable futures that improve wellbeing and gaugingtheir feasibility.

 

Contribution to Program 3                       

In themission statement of Program 3, there is thefollowing message: “Through thereconstruction of the lifeworld concept and by highlighting the reciprocal linkagesbetween rural and urban spaces, Program 3 designs lifeworld of sustainability andwellbeing and co-creates concrete pathways for their realization.”  We are thinking that Sanitationis an essential system for lifeworld. The sanitation contributes to human publichealth, material/resource recycling of society, environmental pollution /ecosystem management. In our project, sanitation value chains for not onlyrural area but also for urban area are discussing. Especially in sanitationvalue chain for urban area, we are designing material and value flow betweenrural and urban spaces. 

Our Program 3 mission statementalso is saying that “Pre-existing, yet latent, diverse socio-cultural elements,such as livelihood styles, lay knowledge, conflict resolution strategies, andthe vitality of the people themselves can be called upon to address problemsand help to chart a course toward possible future societies. Program 3 buildsupon these experiences and knowledge of human-nature interaction to propose concretechanges needed to achieve a sustainable society.”  We could not succeed to install thepractical scale of sanitation system in Burkina Faso at SATREPS project, and weare thinking that the reason  is the lackof analysis on human and social aspects. In our project, we are carefully examining  values of people and community; norm to humanexcreta at our field sites.

 The mission statement includes thefollowing message that “Program 3 will not investigate top-down approaches tosystem change, but will work with local residents, government officials,companies, citizen groups and other various stakeholders to propose sustainablealternatives and gauge their feasibility.” Co-creation of “Sanitation Value Chain” is one of the important pointsin our Sanitation project.

We will contribute to the missionby aiming for the design of life world; showing solutions; proposing thetransition of society, realizing co-creation of sanitation value chain withdiverse stakeholders; founding academic bases on sanitation. Our programdirector, Dr. Saijo is proposing the concept of “Future Design” and he isstressing the importance of “virtual future generation” in design. Oursanitation project has started to discussion on how to include the “virtualfuture generation” in designing process of sanitation value chain.

○Progress and Results in 2017

Project Progress during the FRPeriod to Date

(1) Achievement – 1: Thelaunch of the International Journal on Sanitation: 

The international online journal “SanitationValue Chain” was launched in November 2017. The ISSN is 2432-5066 (online) andthe journal web site is http://www.chikyu.ac.jp/sanitation_value_chain/journal.html. We organized the internationaleditorial board by sanitation specialist from seven countries.

 

(2)Achievement-2: Holding and co-hosting 11 international and domestic conferences,workshops 

We organized eleven meetings in 2017 aslisted in Annex 2. The typical meetings include Zambia Water Forum andExhibition, International Symposium on Green Technology for Value Chains inJakarta, Workshop on Science Communication, Jakarta and Indonesia &Philippine & Japan Joint International Seminar on Water and Sanitation.

 

(3)Achievement-3: Conclusion of research agreement: 

Research Implementation Agreement wasconcluded in accordance with the signing of MOU between Indonesian LIPI and RIHN, and MOU with Zambia University and RIHN wassigned.

 

(4) Achievement -4: Toiletthat can concentrate urine1)-7)

 In order to co-create sanitation valuechain for managing human urine in urban area, transporting urine to rural farmland is essential. The technology required for transporting urine is volume reductiontechnology for cost reduction.  As atechnology to concentrate urine, we examined forward osmosis process this year.The results obtained are as follows: 1) The area of the forward osmoticmembrane required to concentrate 1 L of urine is 55.6 cm2. This areais small enough to install the urine concentration device in the toilet bowl;2) It was shown that 78.6% of ammonia, 97.8% of potassium and 99.6% of phosphatecan be recovered. Output numbers in Annex 2 are 40, 42, 182, 184, 187, 189,191.

 

(5) Achievement -5: Toiletthat can produce Phosphorus fertilizer8)-10)

It is confirmed that phosphorus inurine can be recovered directly from urine as calcium phosphate (DCPD) usingshell as calcium source, and we clarified the reaction pathway and reactionrate of reaction. Thus, by installing a simple shell packed column in a urinecollection pipe of a toilet, it has become possible to make a toilet forproducing phosphorus fertilizer. We will set up a compost toilet withphosphorus recovery function at RIHN and plan to start demonstrationexperiments from March next year. Output numbers in Annex 2 are 182, 188, 190.

 

(6) Achievement-6:New method for analysing exposure pathways of pathogens by molecular biology11)-14) We developed a new method to analyzethe infection route from feces to new infected people. In this method,pathogenic Escherichia coli is separated and quantified by PCR method, andpathway is to be identified from the pathogenic Escherichia coli type. As aresult of applying this method, it was found that the type of Escherichia coliin the drinking water and in feces was different as shown in supplement Fig.2-1,suggesting the importance of other sources of contamination such as live stocks. And three prioritizedexposure pathways are identified: pond bathing, outdoor playing and drinking asshown in supplement Fig.2-2. Output numbers in Annex2 are 49, 193, 194, 195.

 

(7)Achievement-7: Evaluation of inactivation mechanism of virus during urineconcentration15) 

Real Time-qPCR method applied to target sixgenome regions for monitoring MS2( indicator of virus) infectivity during urineconcentration process, and we found that 1) Uncharged ammonia is thepredominant factor for MS2 inactivation; 2) Genome damage is the main mechanism for MS2 infectivityloss; 3) MS2 infectivity loss in urine can be predicted by ion composition and speciation.Output number in Annex 2 is 46.

 

 (8)Achievement – 8: Agricultural Technologyfor compost, urine and reclaimed gray water reuse16)-,18): 

Salinity management of soil isessential when compost, urine and reclaimed gray water is reused in farm land.Mathematical simulation model has been developed for describing fate of saltsin soil system, and the leaching requirement for removing salts is evaluated bythe simulation.  The fate of pathogen insoil system was evaluated, and health risk of worker at the farm land wasestimated.  Output numbers in Annex 2 are36, 43, 45.

 

(9) Achievement-9: Acceptability of sanitation system was evaluated from technical side19)-21):                  We conducted survey on new prototypemodel of composting type toilet at Indonesian Institute of Sciences (LIPI) anda mosque in Sapporo. The results are summaries as follows: 1)Half of the peopleanswered that the bad smell is a point to be checked; 2)70% of respondents worriedabout excreta sticking to the toilet bowl; 3) The new type toilet is acceptable;4)70% was unsatisfied with its size; 40% felt discomfort in terms of theimpression of sitting on the toilet seat, feeling like they might fall into the hole.  We also conducted survey on dewatereddigested sludge for   soil conditioner inIwamizawa, Japan. Output numbers in Annex 2 are  44, 50, 176

 

 (10) Achievement-10: Visualization ofresearch

1) The video, “Samurai-kunSanitation Value Chain” (Indonesian version) was produced and screened at  Bandung City, Water Supply Corporation,Indonesia Science EXPO, Chiara Chon-Dong district residents.  Japanese version was screened at the openhouse event at RIHN; 2)The video showing our sanitation project produced andscreened  at Indonesia Science EXPO and  Workshop on Science Communication; 3)The eventvideo archive was carried out; 4) Participated in RIHN project on visualizationof state-of-the-art research.

 

 (11) Achivement-11: Questionnaire on customsand norms concerning excrement / excretion behaviour 

Japanese version questionnaire hasbeen prepared. In this questionnaire, we examine the following items: purification/ uncleanness, norms / preferences for excretion behaviour, norms / preferencesfor products used by compost, reclaimed wastewater.

 

(12) Achievement-12: Build relationship with actors onthe field site

Indonesia site:  1)We had meeting with local officials, leadersof  neighbourhood association, staffs ofelementary school of this district (See supplement Fig.2-4); 2)We conductedsurveys on health and nutritional status, hygiene environment and behaviour,for elementary school children.

Ishikari site:  1)We designed the structure of water sourcemanagement system coordinated with local high schools / local governments (supplementFig.2-5);  2) we made a meeting with userunions small-scale water supply;  3) Wedesigned technology packages (membrane processing, sensoring, data handling)suitable for autonomous water supply.

Zambia site:   1) Weestablished "Children's Club" to conduct action research with localyouth group in Lusaka's peri-urban area and we organized the meeting of "Children'sClub" (supplement Fig.2-6); 2) We discussed on the current sanitation situationwith them.

Burkina Faso site:  1) We completed the negotiation with localNGO for conducting the questionnaire survey; 2) We confirmed the existence of awaste scraper and recognized the necessity of analysing their actual situation.

○Future Themes

(1) Four Research Topics to achieve the goals

The project isproposing new concept, Sanitation Value Chain, which has the following basicpolicies: 1) Put values of people and community in the centre of discussion,and prepare sanitation system to drive this value chain; 2) Design thesanitation system by focusing on direct incentive for individual users andcommunity; 3) Recognize a sanitation system as an integrated system with socialand technical units; 4) Design the sanitation system by making a good matchingbetween social characteristics and prerequisites of technologies. Accordingly, the goals of this research project are to: 1) propose the conceptof Sanitation Value Chain as relevant to both developing and developedcountries; 2) design several pilot studies demonstrating the significance ofsocietal, academic, and professional involvement in the co-creation of this value chain; and 3)contribute to the establishment of a new interdisciplinary academic foundationregarding sanitation. Inorder to achieve the goals, we will study from four points of views (Topics 1,2, 3 and 4) as shown in Supplement Fig.5-1.

InTopic -1(Life and Sanitation), the following six research activities areplanned: (1-1)Field survey for analyzing values and Happiness of people; (1-2)Field and literature survey on norm to human excreta of current situation aswell as historical change; (1-3) Field and literature survey for re-evaluationof the value of sanitation system; (1-4) Field and literature survey foranalyzing the mismatch between prerequisites of sanitation technologies andregional specific characteristics of human and community by gathering failedcases; (1-5) Field and literature survey on historical change of sanitationsystem in target areas; (1-6) Matching the values of people, community andvalue  provided by sanitation system.

InTopic -2 (Technology), the following four researchactivities are planned: (2-1) Literature survey on prerequisites of sanitationtechnologies; (2-2) Field and literature survey on “Prerequisites of sanitationtechnologies by gathering success cases; (2-3) Field and literature survey forre-evaluation of the value of sanitation system; (2-4)  Field and literature survey for analyzing the mismatchbetween prerequisites of sanitation technologies and regional specificcharacteristics of human and community by gathering failed cases.

 InTopic-3 (Co-creation of sanitation value chain), the following fouractivities are planned: (3-1) Identifying stake holders and understanding thestructure of values of people and community; (3-2) Analyzing Hierarchy andstructure of stakeholders’value chain and evaluationof their affinity; (3-3)Developing the co-creation process; (3-4)Demonstrating co-creationof sanitation value chain.

 In Topic-4 (TD visualization),we will develop a transmission method by various media and methods of ourconcept and research results. We are strongly recognizing the importance of thevisual image as one of the expression methods of the outcome.

 

(2) Fields 

 The project performs the field study at 1) therural area in Ishikari River Basin; 2) the rural area in Burkina Faso; 3) theurban slum in Indonesia; and 4) the urban slum in Zambia.

 

(3) Activities in 2018     

T1 Lifeand Sanitation group:

1) Positioning of Excretion and toilet in thehistory of humanity (humanization, settlement). We will start field survey inCameroon (hunter gatherer society, agricultural society, rural town, slum ofthe capital); 2) Field survey is conducted in Burkina Faso to discuss about”mismatch between sanitation technology and values of local community duringdevelopment assistance”; 3) By using Best & Worst scaling method, customsand norms on excrement and excretion behaviour is analysed in Indonesia,Zambia, Burkina Faso.

 

T2Technology group: 

1) Analysis of prerequisites andmaterial flow of sanitation technologies; 2) Revaluation of value of sanitationsystem (Developing new methodology for identifying exposure pathways of pathogens);3) Analysis of Value Chain for wastewater treatment + sludge agriculture use atIshikari; 4)Developing new sanitation technologies having a differentprerequisites: disinfection method for solids; nutrient recovery from urine)

 

T3Co-creation group:

1) Identifying actors related to sanitation andvisualizing their value chain;  2)Analysinghierarchy and affinity of their value chains at Indonesia and  Ishikari; 3) Implementation of residents(children) participatory action research at Zambia, Indonesia, Ishikari.

 

T4 TDvisualization group:

1) Prototyping short conceptvideo using the characteristics of each image expression;  2) Archiving video of events for sharinginformation among researchers dotted in remote areas.

 

Indonesiateam:

Theprevious study and FS study22) have given the tentative idea forinstalling sanitation system as shown in Supplement Fig.5-2. The field surveyat the urban slum in Bandung, Indonesia and stakeholders’ analysis includingthe interview to the Islam Leaders have shown that 1)organic production inagriculture is their tradition; 2) farmer would like to have organic fertilizerand organic products are traded in good price in the market; 3)reuse ofrecovered resources from human excreta is possible in the Islamic context ifthe excreta is treated adequately; 4) one idea is that users of sanitationsystem might be able to sell their excreta to farmers because of theirfertilizing value; 5) collection system of solid waste system is working verywell in the slum area currently, and this current collection system will beused for collecting urine and compost. Therefore, for co-creating sanitationvalue chain, we will continue to perform a trans-disciplinary approach withactors.

 

Ishikariteam:

Since therural community in Ishikari is becoming impoverished because of depopulation andaging of the community. As a preliminary research toward co-creation ofsanitation value chain, we will study the process of co-creation for therealization of a better mechanism for regional autonomous water supply. In2018, we will continue to work on 1) creating a water source management systemby regional stakeholders; and 2) Studying  technology package suitable for regionalautonomous water supply. We will also start to preparation for expandingactivities to sanitation values chain.

 

Burkina Fasoteam:

 SupplementFig.5-3 shows the possible sanitation value chain of people in rural area,Burkina Faso23).  Sanitationvalue chain is connecting agricultural chain and finance chain. We will continue to work forco-creating sanitation value chain in rural area. As discussed in Chapter 2, we confirmed the existenceof a waste scraper and recognized the necessity of analysing their actualsituation. Therefore we will start to work on sanitation value chain in urbanarea, Burkina Faso. The tentative idea of actors in the chain are 1) user ofdry toilet (selling their excreta to collector); 2) collector of human excreta(scooping human excreta by vacuum tanker and transport to resources recoveryfacility);  3) energy supplier(recovering organic matter and producing heat energy ); 4) fertilizersupplier(recovering P, K, N); 5) farmers in urban and rural area; 6) social capitalistfor supporting collector of excreta, energy and fertilizer supplier. We willalso try to consider the possibility to operate this value chain by private sector.
