Knowledge evolution within human urine recycling technological innovation system (TIS): Focus on technologies for recovering plant-essential nutrients

Published
By

”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.

New Horizon Europe Project “P2Green” will pilot urine dehydration technology in Gotland!

Published

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 VinnerĂ„s 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.

We’re hiring! Two PhD student positions on development and assessment of next generation sanitation systems that recycle urine

Published

Our group has two new positions for hiring PhD candidates –

PhD position in technology development of next generation sanitation systems. Link: https://www.slu.se/en/about-slu/work-at-slu/jobs-vacancies/?rmpage=job&rmjob=7343&rmlang=UK

SLU has developed a new technology to treat source-separated human urine, where fresh human urine is chemically stabilised and then evaporated to produce water and a solid fertilizer. The technology has been piloted in several locations across Sweden (e.g., at the offices of VA Syd in Malmö). If implemented globally, human urine could substitute about one-quarter of current nitrogen and phosphorus fertilizers worldwide.

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

PhD position in sustainable assessment of new sanitation systems. Link: https://www.slu.se/en/about-slu/work-at-slu/jobs-vacancies/?rmpage=job&rmjob=7342&rmlang=UK

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

Within our VR finance project Insect farming for feed production and organic waste management in Benin we now welcome three guests from Benin that will stay with us for a month to learn and exchange knowledge on the BSF technology: Daniel Dzepe, Carline Santos and Claude Gande (seen  in front of our BSF containers at Ultuna campus). Read their personal presentations below.

 

Hi! My Name is Daniel DZEPE, I am a PhD holder working with the International Institute of Tropical Agriculture (IITA), Benin on Black Soldier Fly (BSF). Being at the Department of Energy and Technology of SLU for one month internship with Dr Cecilia Lalander’s team means a lot to me since I have been reading her interesting publications since my Masters. I will be working on BSF composting technology with Viktoria and the other technicians in the lab. Although I already have a good experience of BSF technology, especially regarding the rearing and bioconversion processes, I am so confident that my time in this team will improve my skills and knowledge and will probably allow me to get more opportunities in this field in the future. I will stay until the end of the month, and I am already ready to enjoy my stay with my new colleagues.

Hello. My name is Carline Santos, i’am researcher in Molecular genetics and plant protection from International Institue of Tropical Agriculture (IITA), Benin (West Africa). My work focus on « impact of Black Soldier Fly (BSF) Frass on vegetable crops production and pest management ».

I came at SLU at the Department of Energy and Technology for one month internship to learn more about Black Soldier Fly (BSF) technologies for organic waste management. I’m very happy to join Dr Cecilia Lalander’s team and i want to thank SLU and everyone for this training  opportunity.  I would like to thank specifically Dr Cecilia Lalander, Dr Laura Riggi and Viktoria Wiklicky for your assistance since we are arrived.

We had the joy, after waiting for two years, due to COVID, to finally listen to Madeleine Fogde’s lecture “Communication counts” as a part of the program of becoming honorary doctor at the NJ faculty at SLU. It was interesting to hear about the importance of communication and how a response to a question about how to construct sustainable sanitation after a natural disaster in Mozambique, that was answered by Prof Emeritus HĂ„kan Jönsson and lead to several installations of ecological sanitation systems during the 1990-ies. Later this also lead to a long-term collaboration on sustainable sanitation and now we say welcome for becoming a part of SLU. Madeleine’s presentation starts 14 min into the video below.

I am originally Syrian and moved to Sweden about six years ago. I could not finish my last year of studying biochemistry at the University of Aleppo because of the war there. But with a lot of optimism and self-challenge, I was finally able to return to the bench of scientific research as a second-year student in the pharmaceutical and food technology at Folkuniversitetet in Uppsala, where my studies covers the entire chain of production from idea to product with hygiene requirements, process technology, process chemistry and knowledge of relevant legislation. With the aim to improve the health and quality of life of the population and work with the sustainable nutrition of the future through qualified practical work in medicine and the food industry.

Fortunately and with great happiness I was recently accepted as an intern at SLU ,as a laboratory assistant  for two and a half months in a project fly larvae composting, where organic waste is converted into animal feed (fly larvae) and organic fertilizer (treatment residues).
