My name is Abdullah Al-Saadi. I am originally from Iraq and I live in Finland. In Iraq, I have completed my bachelor degree in Chemical engineering. In Finland, I’m studying a Bachelor degree in Environmental engineering at the final stage. In SLU, I am doing my internship and Bachelor’s thesis project in urine treatment, which will focus on the fate of organic compounds in urine. I will work at SLU for the next 5 months.
My name is Ali Mehaidli. Prior to my arrival here, I was living in Finland, studying Environmental Engineering at Tampere University of Applied Sciences. At SLU, I will be working with the urine treatment research group. My focus will be on the fate and stability of nitrogen during urine dehydration treatment. My internship and thesis project began in January, and I will be here till early June.
Björn Vinnerås, Jenna Senecal and Jennifer McConville attended the startup-meeting in Hannover during the second week of January. Included in the project from SLU is also Prithvi Simha and two PhD students under employment. Our main work is within the “Swedish pilot region”, where we will focus on the upscaling of the urine dehydration process. Our focus is the first two work packages WP1 – Blue printing the regional clusters and WP2 – Monitoring and assessing the benefits. Jenna was presenting the Swedish pilot region with the full cycle of urine collection to food production. See more at the project home page https://p2green.eu/
We have exciting news! The Swedish Research Council FORMAS has granted funding for our project called RECAPTURE: Circular Economy Certification and Production of Urine Fertiliser. RECAPTURE is a collaboration between #SLU, #Sanitation360, #Ecoloop and #RISE, and has 3 short-term goals: 1) optimization of fertiliser formation to work with conventional farming equipment; 2) review the applicability of SPCR178 certification for urine and other emerging products; 3) conceptual idea of a tag-on to fertiliser certifications to include environmental aspects.
My name is Jade Borel and I come from France, Grenoble. I am in the third year of environmental engineering school in Rennes. At SLU, I am part of the urine drying research team. I will work with urease enzyme and analyse how urine salts affect enzymatic activity. My intership started early November and I will be staying until the end of January.
My name is Liudmila Nazarova and I am coming from Russia, Saint-Petersburg. I am a fourth-year Environmental Engineering student at Tampere University of Applied Science (Finland). I am part of the Kretsloppsteknik research team at SLU. I am working on the fate and chemical degradation of biodegradable polymers in wastewater at different process conditions. I will be working in the group from September until the end of November.
We’re happy to share that the #Bolivia project on #urinedrying that we started in 2018 will continue for another four years through new funding from Vetenskapsrådet / Swedish Research Council. In the project, we will be developing novel chemical pellets that can capture all the nutrients in urine, while removing organics pollutants and malodour-causing substances. The pellets will be evaluated against real-life aspects and natural contaminants before they are field-tested in urban settings in Bolivia. Project partners in Boliva include Luis Fernando Perez Mercado and Mercedes Iriarte from Centro de Aguas y Saneamiento Ambiental at the University of San Simon in Cochabamba.
”Knowledge development and diffusion” is a key function in developing technological innovation systems (TIS), especially early in the formative phase. If you are interested in knowing whether the current knowledge base on nutrient recovery technologies is sufficient to further develop urine recycling TISs, then this paper is for you: https://lnkd.in/dRbqn-8g
We ( Robin Harder, Prithvi Simha, Bjorn Vinneras, Jennifer McConville and myself) conducted a bibliometric analysis and comprehensive mapping of existing urine recycling knowledge and used a novel multi-criteria framework to evaluate whether the development of such a TIS is feasible. Results showed that the rate of publications and knowledge diffusion increased sharply in 2011–2021 compared to 1990–2010. However, the function still has insufficiency in some criteria. … paper is attached.
A consortium of 32 partner organisations from 12 European countries and Switzerland including SLU and Sanitation360 have justed signed the Grant Agreement for a four-year Horizon Europe Project aiming to “close the gap between fork and farm for circular nutrient flows” short P2GreeN. From our group in Sweden, Jenna Senecal, Prithvi Simha, Jennifer McConville, and Björn Vinnerås will participate in the project. The project will start on the first of December 2022, and is coordinated by agrathaer GmbH and Leibniz Institute of Vegetable and Ornamental Crops (IGZ) e.V.
P2GreeN’s overall objective is to foster a circular material flow system between urban and rural areas thereby restoring the coupling of the water-agri-food system following the 3R principle “Reduce, Reuse, Recover”. To achieve this, P2GreeN will develop new solutions for the circular economy to halt and eliminate nitrogen (N) and phosphorus (P) pollution by connecting blue urban with green rural infrastructure, focussing on circular nutrient flows of nitrogen (N) and phosphorus (P), two important plant nutrients and at the same time water polluters. This objective will be achieved through the implementation and exploration of innovative N and P recovery solutions for the utilization of human sanitary waste from urban settlements and its conversion into safe bio-based fertilizers for agricultural production in three pilot regions.
The aim of this PhD project will be to continue the technology development, with focus on performing research in support of scaling up the urine dehydrating sanitation system. During this project, lab-scale treatment systems available at SLU will be scaled up into full scale operations for the production of 25 kg of dry fertilisers per day. The project will involve both fundamental research (e.g., evaluating changes to composition and properties of urine during dehydration) and implementation research (e.g., developing reactors for stabilizing urine at the toilet). The PhD project will be part of a larger Horizon Europe Research and Innovation Action collaborative project, “P2Green” (Closing the gap between fork and farm for circular nutrient flows), where three pilot regions will scale-up and implement innovative sanitation technologies in real-life conditions. The Island of Gotland will be one of the pilot regions where SLU will scale up and validate urine dehydration. Contact: Bjorn Vinneras
The aim of this project is to investigate the potential for new sanitation innovations to provide sustainable benefits by quantifying trade-offs in terms of environmental impacts, costs and uncertainties. The primary focus will be on developing decision-support tools that allow decision-makers to weight trade-offs and test options for integrating new sanitation systems into existing infrastructures. Methods used will include life cycle assessment, cost-benefit analysis and systems dynamic modeling. The assessment methods will be applied on case studies of emerging technologies for nutrient recovery from urine and wastewater in the context of an EU project. The work will include interaction with stakeholders to co-design of development trajectories for integrating new sanitation systems into the local context. Contact: Jennifer McConville
