Trying the new role-playing game RECLAIM

Published

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.

Press Release: Nitrogen should be given higher priority than phosphorus when recovering plant nutrients from wastewater

Published

Phosphorus has long been the highest priority when recovering plant nutrients from sewage. However, nitrogen should be given top priority according to a new evaluation of criteria linked to the use of non-renewable resources, vulnerability, and potentially reduced climate impact. 

When prioritizing recovery from wastewater, phosphorus often emphasised as it is necessary for all life and as it is stated to soon run out (Peak phosphorus). There is reason to question this one-sided emphasis on phosphorus. The report “Phosphorus, nitrogen, potassium and sulphur – access, vulnerability and recovery from wastewater” reviews a) risks linked to the production of artificial fertilizers from non-renewable resources; b) the vulnerability of Swedish plant production to blocked import of artificial fertilizers; and c) potentially reduced climate impact in the recovery of plant nutrients from wastewater.

All investigated criteria show that the recovery of nitrogen from wastewater should be given highest prioritized, and significantly higher than the recovery of both phosphorus and potassium. According to its directives, the presently working governmental investigation on sewage sludge is obliged to submit a proposal focused on recycling of phosphorus from sewage sludge by 10 January 2020. The risk is obvious that the wastewater sector will be forced to devote considerable resources to phosphorus recovery, resources that should be invested in nitrogen recovery to best contribute towards increased sustainability for both the wastewater system and the entire food system.

We are looking for a Post-Doc to join our team & work with sustainability assessment

Published

The environmental engineering group at SLU – Swedish University of Agricultural Sciences is looking for a post-doc to join our team. Please, spread this announcement in your networks. Apologies for cross-posting. We are looking for a post doc to strengthen our research on sustainability assessments of technologies for resource-recovery from urban organic waste, i.e. wastewater fractions and organic solid waste.
We are particularly interested in sustainability assessments, e.g. life cycle assessment, cost-benefit analysis and technological innovation studies of systems designed for the recovery of nutrients from wastewater.

SIDA International Training Programme at Kretsloppsteknik

Published

Earlier this week, a few members of Kretsloppsteknik hosted a group of SIDA’s International Training Programme participants in Uppsala. NIRAS on behalf of SIDA implements a number of International Training Programmes. Kretsloppsteknik is involved as part of this program through NIRAS with focus on participants from both Asian and African countries. During these visits, we teach, present, and do technology demonstration through field visits talking about safe nutrient recycling, source-separating sanitation systems, management of organic wastes, socio-technical systems analysis, etc.

Sanitation360 AB and Science Park Gotland to work together on developing urine drying

Published

Last week, Björn, Jenna and Prithvi were in Visby, on the Island of Gotland to meet with Daniel Freeman from Science Park Gotland (SPG), an organisation that supports new businesses in Gotland to take the next step. We are happy to share that we came to a mutually satisfactory agreement and found a way forward to work together so that we can develop, implement and commercialise the group’s research on urine drying through its start-up company – Sanitation360 AB.

SPG will provide S360 with access to business advice, financial support, opportunity to participate in incubator joint activities, open co-working office space, and contribute to the development of our company. We are happy to have such support and are eager to get things rolling! At the same time, we are also grateful for the support we have received from SLU Holding in the past that has helped us get to the stage we are at now.

Pharmaceuticals in source separated sanitation systems: Fecal sludge and blackwater treatment

Published

In this article, the occurrence and fate of 29 multiple-class pharmaceuticals (PhACs) in two source separated sanitation systems based on: (i) batch experiments for the anaerobic digestion (AD) of fecal sludge under mesophilic (37 °C) and thermophilic (52 °C) conditions, and (ii) a full-scale blackwater treatment plant using wet composting and sanitation with urea addition.

The Cary 620 FTIR microscopes coupled with Cary 660 IR spectroscopes and FTIR microscopy is ready for microplastic analyses

Published

After investing 1.5 million Swedish Crowns, the new Cary 620 FTIR microscope coupled with Cary 660 IR spectroscopes and FTIR microscopy is finally installed and ready for operation for analyses of microplastics in Department of Energy and Technology. Using the Focal plane array detector and the FTIR spectrophotometer, the instrument will be used to implement chemical imaging to identify, quantify and determine the particle size of micro plastics and other substances.  The instrument is homed by Environmental technology group under the responsibility of Sahar Dalahmeh.

Participatory design of biochar filters for small scale wastewater treatment

Published

FORMAS has granted 3 mkr to implement multi-actor engagement and particpatory design approach to understand how socio-technical factors affect the development of biochar-based systems as an alternative for onsite wastewater treatment in Sweden. Based on the participatory design criteria, laboratory and demonstration biochar-based treatment systems will be implemented. The technical performance and maintenance and operation requirements will be evaluated with the relevant stakeholders. Sustainability of biochar solution will be assessed in a multi-criteria sustainability assessment, including social, economic and environmental impacts. The project is lead by Sahar Dalahmeh from the environmental technology group.

Eight million Swedish kronor to implement research about Cities with less microplastics

Published

With a total fund of 8 million Swedish crown, Sahar Dalahmeh her collaborators will evaluate contribution of stormwater from roads in polluting the environment with microplastics and will investigate how to integrate green infrastructure into pollutant removal, by assessing the potential, efficiency and design of road-side filters (bark and biochar) for removing MP from stormwater, to function as planting sites and to retain water. The project comprises four work tasks: 1) To assess the composition, particle size and quantities of MP in stormwater from different urban sources; 2) to assess and compare the efficiency and potential of road-side filters made of biochar or bark filters in removing MP and in acting as green beds, and compare them with soil beds; 3) to develop a conceptual design for road-side green filters for MP removal; and 4) to assess their environmental sustainability in terms of e.g. climate change and water quality impacts. The project will be implemented within four years in collaboration with researchers from Aalborg University in Denmark and Malmö University
