Launching the Guide to Sanitation Resource-Recovery Products & Technologies

We are pleased to announce the we will soon be publishing a Guide to Sanitation Resource-Recovery Products & Technologies! To launch this publication we are hosting a webinar on the SuSanA forum.

When? 22nd of October, 2020 between 14:00-15:00 CEST. Details and registration can be found on this link: https://www.susana.org/en/news-and-events/sanitation-events/upcoming-events?details=170

This Webinar is organized by the Swedish University of Agricultural Sciences (SLU), Makerere University and the Research Institutes of Sweden (RISE) in collaboration with SuSanA working group 5 as part of the SPANS research project. It will present a new publication related to resource recovery from sanitation systems – the Guide to Sanitation Resource-Recovery Products & Technologies. The publication is designed as a supplement to the Eawag Compendium of Sanitation Systems and Technologies. It provides an overview of the possibilities for resource recovery from sanitation and provide guidance on treatment processes to achieve safe products for reuse. The webinar will introduce the guide, including an overview of the technologies and products that are covered in the document, and discuss how the information sheets can be used a reference book for sanitation planning and decision-making.

New Post Doc in the group will work on wastewater sustainability assessment

My name is Priscila Lima and I have just started a postdoc within the Environmental Engineering group. I am originally from Brazil and I have lived in the US and in Denmark for some time. I am an Environmental Engineer that has been working with solid waste management systems ever since my bachelor’s thesis. Most recently, my PhD thesis was on Environmental Assessment of solid waste systems for Brazil and a case study in my Municipality in the west central region of the country, and I used Life Cycle Assessment for this. Before coming to Sweden I was performing research in my hometown, with a main focus on Life Cycle Assessment of different types of waste. Now, I have joined Jennifer at Kretsloppsteknik in a project to assess the sustainability aspects of waste systems, with main focus on nutrient recovery from these systems.

EVAS – a practical tool to assess the sustainability of small wastewater treatment systems in low and lower-middle-income countries

Claudia Cossio, a former PhD student affiliated with the group, has published an article regarding the development and application of an Excel-based tool to holistically evaluate the sustainability of existing wastewater treatment plants  in low and middle income countries. Many small wastewater treatment systems (WWTSs) in low and lower-middle income countries face challenges to achieve optimal performance and acceptable levels of sustainability. In order to provide guidance for operation of these systems, Claudia and her colleagues developed a practical tool to diagnose the actual status of WWTSs and identify weak areas for further improvement.

The article is available Open Access – https://doi.org/10.1016/j.scitotenv.2020.140938

The Excel tool is available on the Chalmers website – https://research.chalmers.se/en/publication/516714

Comparing treatment options for nutrient-recovery from fecal sludge

The latest publication from our project in Uganda is on-line. We present a multi-criteria assessment method for planning and decision-making related to options for recovering nutrients from fecal sludge. We apply the method to the case of Kampala, Uganda. However, we start with a broad list of potential technologies and there are quite a few references for more information on these technologies – so the method and data should be interesting for other people interested in options for nutrient-recovery.

Read the full paper here: McConville, J. R., Kvarnström, E., Nordin, A. C., Jönsson, H., & Niwagaba, C. B. (2020). Structured Approach for Comparison of Treatment Options for Nutrient-recovery from Fecal Sludge. Frontiers in Environmental Science8, 36.

Fecal sludge & sewage treatment infrastructure investments & operating costs in Kampala, Uganda

Like many low-income countries, Uganda is struggling to provide sanitation to its inhabitants. Meeting the Sustainable Development Goal related to sanitation (SDG6) will require major investments in sanitation. This study uses the concept of service regimes to analyze existing sanitation infrastructure and services and their respective costs. The service regimes investigated are the sewage regime and the fecal sludge (FS) regime. The results show that approximately 56% of the fecal flow in Kampala is estimated as ‘safely managed’. The results also show that the annual per capita costs for the sewage regime (USD 186) are more than 13-fold those for the FS regime (USD 14). Additionally, there are large differences in subsidies between the regimes. When allocating public funds, decision-makers are advised to consider (i) number of customers within regimes, (ii) total capital and operating costs of services, (iii) cost allocation between stakeholders, and (iv) infrastructure performance.

Trying the new role-playing game RECLAIM

We ended the year 2019 with a very fun activity – trying out a new role-playing game developed by Jennifer McConville and her colleagues. RECLAIM is an exciting, dynamic board game whose main purpose is to act as a learning tool for participatory decision-making on water and sanitation issues. There are several stakeholders represented in the game, and all players are allowed to role play each stakeholder, and collaborate to provide and improve the sanitation situation of their region. The board itself is modular in the sense that it can be arranged to depict that group of players’ cities, be it a peri-urban area in Uganda or the urban area of central Stockholm. Not only did we have a lot of fun role playing, but we also found it to be quite intuitive. At the end of the game, we as players reflected on how RECLAIM can be a great tool that can help community members to come together, share, and help understand each other’s perspective on sanitation and how such games provide an ideal platform to make that happen.

Role-playing and gaming are active learning tools, which are useful for learning relationships between technology and society, problem solving in complex situations and communication. For further information about RECLAIM, get in touch with Jennifer McConville at Kretsloppsteknik.
