The need for a more circular use of nutrients, notably phosphorus (P), has been widely discussed in Sweden, not least in response to the release of the new enquiry on sustainable use of sewage sludge (SOU 2020:3). But what would a transition to a circular economy for phosphorus look like? How much phosphorus is needed for… Continue reading Can Sweden achieve a circular economy for phosphorus?

Publication on field testing alkaline urine dehydration at pilot-scale in Finland
In early 2019, we designed and installed a pilot shell system to dry fresh urine collected from about 100 toilet users each day (or a maximum of 30 liters of urine day-1). The system was implemented at a Finnish army training ground (Camp Mauri) belonging to Pori Brigade, which is a garrison in Säkylä, Finland… Continue reading Publication on field testing alkaline urine dehydration at pilot-scale in Finland
Publikation om fältarbete av alkalisk urintorkning i pilotskala i Finland
I början av 2019 designade och installerade vi ett pilotskalssystem för att torka färsk urin som samlats in från cirka 100 toalettanvändare varje dag (eller högst 30 liter urin dag-1). Systemet implementerades på en finsk arméutbildningsplats (Camp Mauri) som tillhör Pori Brigade, som är garnison i Säkylä, Finland och användes under en period av tre… Continue reading Publikation om fältarbete av alkalisk urintorkning i pilotskala i Finland
New book chapter discusses alkaline urine dehydration at scale
In a bio-based circular economy, domestic wastewater has a significant role to play. By separating wastewater into different fractions at the source, it is possible to create new pathways for recycling resources. In a book chapter published in Current Developments in Biotechnology and Bioengineering, Simha et al. discuss about the most nutrient-rich wastewater fraction, human… Continue reading New book chapter discusses alkaline urine dehydration at scale
New publication on fate of Ascaris at various pH, temperature and moisture levels
A new study assessed the inactivation of Ascaris eggs under various conditions and observed that the exposure of Ascaris eggs to elevated pH (10.5–12.5) at temperatures <27.5 °C for >70 days had no effect on egg viability. To accelerate the inactivation of STH, an increase in the treatment temperature is more effective than pH increase.… Continue reading New publication on fate of Ascaris at various pH, temperature and moisture levels
New Publication on drying human urine using different alkaline media & temperatures
In a study recently published in Science of the Total Environment, we present results from a study that investigated drying of fresh source-separated human urine in five different alkaline media (pH > 11) at elevated temperatures (50 and 60 °C) with minimal loss of urea, urine’s principal nitrogen compound. We found that it was possible to concentrate urine 48… Continue reading New Publication on drying human urine using different alkaline media & temperatures
Using Hermetia illucens larvae to process biowaste from aquaculture production
A paper was published in the Journal of Cleaner Production as a result of the partnership established between the Environmental Engineering Research Group at SLU and the PhD candidate Ivã Guidini Lopes, a researcher from São Paulo, Brazil. This paper addresses the management of waste generated in aquaculture enterprises (fish carcasses) by larvae of the… Continue reading Using Hermetia illucens larvae to process biowaste from aquaculture production
Pharmaceutical pollution of water resources in Nakivubo wetlands & Lake Victoria, Uganda
This study investigated the occurrence and removal in wastewater and water bodies in Nakivubo wetland area and Inner Murchison Bay, Lake Victoria, of common prescription and non-prescription pharmaceutically-active substances (PhACs) sold in Kampala city, Uganda. A questionnaire was sent to 20 pharmacies in Kampala, to identify the most commonly sold PhACs in the city. During… Continue reading Pharmaceutical pollution of water resources in Nakivubo wetlands & Lake Victoria, Uganda
