NÀsta veckan kommer Annika och Cecilia frÄn Kretsloppsteknik till Uppsala stadsbibliotek för att diskutera kring varför vÄrt nuvarande vattenburna sanitetssystem inte Àr sÄ bra som mÄnga kanske tror och presentera vad vi tror kommer vara framtidens sanitetslösningar, som pÄ ett bÀttre och mer effektivt sÀtt tillvaratar och hanterar resurserna i vÄrt avlopp.
à rets evenemang hade temat under ytan, och tog upp ett brett spektrum av intressanta Àmnen, frÄn djuphavsforskning till psykologin kring hur vi ser pÄ och hanterar klimathotet. VÄrt inspel syntes pÄ menyn, dÄ Axfoundation bjöd pÄ sin vision av framtidens mat. Det bjöds pÄ kÄlrot och pumpa, gödslad med frass (insektskompost) frÄn vÄra fluglarver som utfodrats med livsmedelsavfall och till det serverades det bÄde kyckling och regnbÄgslax som har fÄtt insekter som sin huvudsakliga proteinkÀlla. Larverna som anvÀndes var uppfödda pÄ Ätertaget bröd och grönsaksavfall frÄn Sorunda grönskshallar.
This year’s event had the theme below the surface, and brought up a wide range of interesting topics; from deep-sea research to the psychology of how we look at and manage the threat of climate change. At dinner Axfoundation presented their vision of future food and thatâs where we came into the picture. On the menu were cabbage and pumpkin fertilized with frass (insect compost) from our fly larvae reared on food waste, served with chicken and rainbow trout that had insects as their main protein source. The larvae used in the feed were reared on reclaimed bread and vegetable waste from Sorunda grönsakshallar.
I samband med MORTTI-projektet testas vÄr grupps urinsorteringsteknologi i fÀlt vid Björneborgs Brigads militÀrtrÀningsbas i Finland. Tidigare under veckan deltog vÄra gruppmedlemmar Caroline Karlsson och Prithvi Simha tillsammans med MORTTIs partners i ett organiserat mediaevent med flera lokala och nationella mediakanaler.

Den 8 april arrangerade MORTTI-projektets partners en mediadag för att uppmĂ€rksamma vĂ„rt projekt i Finland som har varit igĂ„ng sedan första veckan av mars. Pilotprojektet, som pĂ„gĂ„r i tre mĂ„nader, stabiliserar och torkar urin frĂ„n soldater och skapar samtidigt under sĂ€kra förhĂ„llanden en torr gödsel i pulverform. Projektet testar urinsorteringsteknologin utvecklad av vĂ„r forskargrupp i fĂ€lt. Caroline Karlsson och Prithvi Simha representerade Kretsloppsteknik pĂ„ mediadagen.Â
Within the MORTTI project, our group’s urine drying technology is being piloted at Pori Brigade’s military training site in Finland. Earlier this week, as part of an organised media day event, members of our group Caroline Karlsson and Prithvi Simha alongwith MORTTI project partners interacted with several local and national media outlets.

On the 8th of April, the MORTTI project partners organised a media day for our project in Finland that has been operational since the first week of March. This 3-month pilot stabilises and dries human urine collected from soldiers, to be safely recycled as a dry powder fertiliser. The project pilots the urine drying technology developed by our research group at SLU. Representing Kretsloppsteknik at this event were Caroline Karlsson and Prithvi Simha.
Proposed Title: Identifying effective transport systems and logistics for new sanitation systems that produce fertilisers from human wastes.
Credits:Â 30 credits; Level:Â Advanced
Subject:Â Technology or Environmental Science
Start: As soon as possible
Background: In the sanitation sector, there is growing recognition that we urgently need to change the way we handle, treat, and recycle human wastes in our environment. At the Swedish University of Agricultural Sciences (SLU), the environmental engineering research group has developed the âurine dehydratorâ, an exciting new technology that converts liquid human urine into a hygienic, commercial-quality, dry fertiliser. The technology involves two steps, (a) using a urine-diverting toilet at home, to separately collect urine without the faeces; and (b) drying the urine within an alkaline substrate that placed is placed in the urine dehydrator.
We are looking for a motivated and enthusiastic student to assist in developing a computer model that simulates the impacts of different technology choices for management of wastewater flows. The model will be incorporated into a serious game that we are developing to guide sanitation planners and decision-makers. The game is a multi-stakeholder, spatial planning game for municipal sanitation which focuses on resource recovery. It will allow for a visual representation of what technologies can be used and what resources can be recovered from sanitation facilities.
