Comparing treatment options for nutrient-recovery from fecal sludge

Published 27 April, 2020
By Prithvi Simha

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.

Kretsloppsteknik at SciFest 2020

Published 6 March, 2020
By Prithvi Simha

We at Kretsloppsteknik have been very active in community outreach and in engaging the public with our research and educational activities. Continuing this tradition, this week you find us at Fyrisov in Uppsala where we have a booth to participate in SciFest 2020 – an inspirational science festival for school students, young researchers and innovators that is co-organized by Uppsala University and the Swedish University of Agricultural Sciences. At our booth, we are demonstrating to young minds how we can separately collect and recycle different fractions from the household. We have the crowd stopping black soldier fly larvae composting, a urine-diverting dry toilet and dried urine fertiliser, single use biodegradable PeePoo toilets, biochar filters, and props showcasing how much waste we produce every day per person. All members of the group have taken turns to be at the booth – to talk to kids and inspire them to think differently and see value in what society considers waste. It is quite amazing to see, hear and interact with kids of every age group that stop by our stall. Many were quite active, touching and holding the BSF larvae, bringing their friends to do the same, and appreciating the thinking and reasoning behind recycling waste fractions.

ProCivitas private school for grade 10-12 is a small school with students in the science program and the social science program. The school provide the students with lectures about research once every month, called the lecture of the month, with different themes. This month, the theme was sustainable systems and Lovisa Lindberg from the group went there to talk about fly larvae composting but also Maria Westerholm from a different department at SLU went there to talk about biogas research.

New urine-diverting toilet & test bed for drying urine inaugurated at SLU

Published 27 February, 2020
By Prithvi Simha

On 7th February, we inaugurated our new urine-diverting toilet here at the department of energy and technology, at SLU’s Ultuna campus. The installation was made possible due to a grant from SLU-climate fund that financed the installation together with the Save! Urine diverting flushed toilet from Laufen and SLU’s landlord Akademiska hus. The existing conventional toilet was exchanged with the new Laufen toilet “Save!” as a permanent installation. The urine is led out from the wall and connected to the test bed (the larger box on the side into where the urine drying equipment is installed).

Sanitation360 wraps up the Hiedanranta urine drying pilot – Thank you Tampere & Lielahti Manor

Published 11 February, 2020
By Prithvi Simha

Towards the end of January, Jenna Senecal and Viktoria Wiklicky from Kretsloppsteknik were in Tampere, Finland to decomission our 25 L/day urine drying system that was in operation at the basement of Lielahti Manor house. The system was in use in between June 2019 and January 2020, and was a great showcase of the group’s and Sanitation360 AB’s on-site urine treatment technology, alkaline urine dehydration. Through this project, we demonstrated to our various Finnish partners that our technology is scalable, socio-technically feasbile, and marks a significant step away from erstwhile urine processing technologies. We are very thankful to our various collaborators, partners and stakeholders that helped make this a successful pilot project – Tampere City, Tampere University of Applied Sciences, Hiedanranta Development Programme, city workers, officials, plumbers, subcontractors, research interns, and others.

Live streaming of fly larvae composting project at Hedda Wising School

Published 10 February, 2020
By Lovisa Lindberg

Fly larvae composting has sparked interest in 8th grade students from Hedda Wising school, who wanted to test fly larvae composting on their own.

The aim of the project is to evaluate how simple the system can be and how fast the process goes. The students are driving this experiment with aim to produce feed protein that can be used for chicken or fish production. The substrate is the canteen leftovers that would otherwise become food waste. The project at the school is a part of an EU collaboration project ”Envising” with focus on sustainability.
