Prithvi has joined the editorial board of the journal, Frontiers in Chemical Engineering, as associate editor for the speciality section Environmental Chemical Engineering. The journal publishes rigorously high-impact research on all topics related to chemical engineering, while the speciality section explores opportunities in chemical engineering aimed at addressing environmental problems.

During the Medieval Week, the N2Brew urine project from the group featured strongly in Gotland. In Collaboration with TouchDown Gotland, two female urinals from Lapee have been installed in Visby. Here more about it from Jenna Senecal who was interviewed on P4 Radio: https://sverigesradio.se/artikel/urin-blir-till-vaxtnaring-genom-gotlands-forsta-urinoarer-for-kvinnor

We are very happy that starting next year Dyllon Randall from the University of Cape Town will be at our group as the August T Larsson guest researcher. He will spend one month per semester at SLU over three years, teaching, supervising and working with researchers at the NJ faculty.

Randall’s guest researchership will cement the collaboration between UCT’s Future Water Institute and the SLU. This partnership began in March 2020 when he was invited to work with SLU’s Kretsloppsteknik Research Group in the niche area of urine source-separation-based sanitation systems. Randall and the group’s Bjorn Vinnerås and Prithvi Simha are among a handful of global experts who have been systematically working to develop circular sanitation technologies.

At SLU, the Faculty of Natural Resources and Agricultural Sciences has set aside funds to support internationalization of research in the field of global development. The NJ Faculty Committee on Global Development conducts calls for funds. During this year’s call, two applications were approved, out of which one was decided in Prithvi’s favor. With this funding, Prithvi and his colleagues in Namibia will be able to kickoff a project that they call “WATERSIDE”. The overall goal will be to create the groundwork for developing a transdisciplinary living lab – WATERSIDE (WATER Sanitation In ariD rEgions) focused on education, research and innovation within the subject area of water and sanitation in arid regions. The Kretsloppsteknik Research Group at SLU and the Namibia University of Science and Technology (NUST) are the main partners. In addition, GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit), the Gobabeb Desert Research Institute and Development Workshop Namibia (DW-N) will be involved, while the City of Windhoek, Shack Dwellers Federation of Namibia (SDFN) and Environmental Lawyers Network of Namibia will be associated. The idea is to conduct a series of three workshops in Namibia over the course of the next year, so keep an eye out on our blog to hear more about WATERSIDE.

Bjorn Vinneras, Prithvi Simha and Natnael Demissie from the group were in Copenhagen this week to take part in the IWA World Water Congress.

Natnael presented our work on urine dehydration, focusing on the full cycle – from collection to final consumer product, to show what SLU and Sanitation360 are doing to take the technology to market.

During the congress, there have been many opportunities to meet old and new friends, interact with practitioners and utilities, participate in workshops (e.g., the non-sewered sanitation), and shape the agenda for IWA specialist groups (e.g., ROS – Resource-Oriented Sanitation).

My name is Justus Jalava. I am from Tampere, Finland and I am a third year student in Tampere University of Applied Sciences studying environmental engineering and management. At SLU, I will be working with removal and recovery of phosphorus from wastewater produced by the manufacturer of a novel toothpaste. My objective is to work with determining and analysing which is the most efficient way of phosphorus extraction from a set of possible methods. I will be staying in Uppsala until the start of November 2022.

My name is Isis Conroy. I am originally from the United States but now call Tampere, Finland home. I attend Tampere University of Applied Sciences, where I am in my third year of Environmental Engineering studies. While at SLU, I will be a member of the urine dehydration team. My responsibility is to help test the effect of UV and peroxide on bacterial DNA in human urine to ensure the safety of the finished fertilizer. I will be here until the beginning of November.

My time working on the urine drying project has come to an end. It has been a great privilege to work on this project, and Prithvi and his team have helped me develop both my laboratory and analytical skills. During my time here we have tested ways to stabilise urine as well as develop new analytical methods, and I am looking forward to further developments in these technologies. I have met and worked with some great people who are all working on different parts of the urine drying systems and I wish them all the best for the future.
