JÀmförelse av behandlingsalternativ för nÀringsÄtervinning frÄn avföringsslam

Published

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.

Den senaste publikationen frĂ„n vĂ„rt projekt i Uganda Ă€r online. Vi presenterar en metod för bedömning av flera kriterier för planering och beslutsfattande relaterad till alternativ för utvinning av nĂ€ringsĂ€mnen frĂ„n avföringsslam. Vi tillĂ€mpar metoden pĂ„ fallet i Kampala, Uganda. Men vi börjar med en bred lista med potentiella tekniker och det finns en hel del referenser för mer information om dessa teknologier – sĂ„ metoden och data borde vara intressanta för andra som Ă€r intresserade av alternativ för nĂ€ringsĂ„tervinning.

Luis successfully defended his PhD thesis!

Published

Luis Fernando Perez Mercado successfully defended his thesis “Farm-based technologies for management of risks from irrigation with wastewater-polluted sources in Cochabamba, Bolivia” on April 16.

Link to thesis: https://pub.epsilon.slu.se/16783/1/perez_mercado_l_200324.pdf

A totally new concept with having the evaluation performed over link. All was working well and the defence was a success!

Kretsloppsteknik pÄ SciFest 2020

Published

Vi pĂ„ Kretsloppsteknik har varit mycket aktiva i att nĂ„ ut till samhĂ€llet och att engagera allmĂ€nheten med vĂ„r forskning och utbildningsverksamhet. Genom att fortsĂ€tta denna tradition, hittar du oss denna vecka pĂ„ Fyrisov i Uppsala dĂ€r vi har en monter för att delta i SciFest 2020 – en inspirerande vetenskapsfestival för skolelever, unga forskare och innovatörer samordnade av Uppsala universitet och Sveriges lantbruksuniversitet . Vid vĂ„r monter visar vi dig hur vi kan samla in och Ă„tervinna olika fraktioner frĂ„n hushĂ„llet. Vi stoppar upp folkmassan genom att visa upp vĂ„r kompostering med amerikanska vapenflugslarver, en urinledande torr toalett och torr uringödsel, bionedbrytbar PeePoo-toaletter, engĂ„ngsbruk, biokolfilter och rekvisita som visar hur mycket avfall vi producerar varje dag per person. Alla medlemmar i gruppen har stĂ„tt vid montern för att prata med barn och inspirera dem att tĂ€nka annorlunda samt se vĂ€rdet i det som samhĂ€llet anser vara avfall. Det Ă€r ganska fantastiskt att se, höra och interagera med barn i alla Ă„ldersgrupper som stannar vid vĂ„r monter. MĂ„nga var ganska aktiva, rörde och höll i larverna, fick sina vĂ€nner att göra detsamma och uppskattade tĂ€nkandet och resonemanget bakom Ă„tervinning av avfallsfraktioner.

Kretsloppsteknik at SciFest 2020

Published

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.

ProCivitas privata gymnasium Àr en liten skola med elever som gÄr naturvetenskapsprogrammet och samhÀllsprogrammet. Skolan tillhandahÄller sina elever förelÀsningar om forskning en gÄng varje mÄnad, kallad för mÄnadens förelÀsare, med olika teman. Denna mÄnad var temat hÄllbara system dÄ Lovisa Lindberg frÄn Kretsloppsteknik Äkte dit men Àven Maria Westerholm frÄn institutionen av molekylÀra vetenskaper pÄ SLU Äkte dit och pratade om sin biogasforskning.

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

Published

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).
