Insect protein-based polymer development provides a new alternative resource for plastic production allowing extracting value from food waste. The black soldier fly larvae efficiently convert organic material in the waste into their own biomass which is rich in protein. Using these proteins for plastic production allows taking advantage of the resources in food waste that… Continue reading Master’s project Microplastic solution – Protein polymer from food waste

Master’s Project: Insect protein resource for plastic production
Global plastic production is increasing with growing population and packaging demands. Plastic packaging production is responsible for nearly half of all plastic produced in EU. Currently there are no easy ways to recycle plastic mainly due to existence of multiple types of plastics that are not sorted properly. This leads to a reality that even… Continue reading Master’s Project: Insect protein resource for plastic production
SLU has its own urine-diverting flush toilet!
Today was quite an exciting day at Kretsloppsteknik for the urine drying project as we received our shipment of a prototype of the pioneering urine-diverting toilet developed by EOOS, Eawag and LAUFEN. In the coming month, our group along with SLU and Akademiska Hus will install the toilet at the Department of Energy and Technology.… Continue reading SLU has its own urine-diverting flush toilet!
New publication in the Global Water Pathogen Project about Salmonella
Björn Vinnerås and Annika Nordin have together with R Hasan, S Shakoor and I Keenum compiled current knowledge regarding Salmonella. Our focus in the chapter has been the effect upon salmonella in relation to current practices and available treatment technologies. Treatment technologies for reduction of Salmonella in wastewater fractions can be divided into three main types: chemical,… Continue reading New publication in the Global Water Pathogen Project about Salmonella
Waste management with insects was presented in Honour of Professor Erik Dahlquist
Thursday last week (31/10), Björn and Cecilia from the Environmental Engineering group visited Västerås and presented about waste management using insects in the seminar held in Honour of Professor Erik Dahlquist. Erik Dahlquist is Professor in Energy Technology at the Mälardalen University and has with the help of his long experience in improvements of process… Continue reading Waste management with insects was presented in Honour of Professor Erik Dahlquist
Larvae fed bread get really fat
How does the fat content and composition in the larvae of the black solider fly (Hermetia illucens) change with the diet provided to them? In our latest article published in Waste Management, Nils Ewald and co-authors brings new knowledge on this topic. The study is based on eleven feeding trials were the larvae were fed… Continue reading Larvae fed bread get really fat
New publication on pre-treatment of banana peels for BSFL composting
Alice Isibika and co-authors have published a new study in the journal Waste Management, on the application of pre-treatments prior BSFL treatment of banana peels as a fibrous and nutrient imbalanced substrate to enhance bioconversion ratio. The applied pre-treatments were non-protein nitrogen for balancing the carbon/nitrogen , heat and microbes(fungi and bacteria) pre-treatments for breaking… Continue reading New publication on pre-treatment of banana peels for BSFL composting
Christian Zurbrügg joins Kretsloppsteknik as Adjunct Professor
What a pleasure to now be part of this exciting and motivated team at SLU !! My home-base is at Sandec – the Department of Sanitation, Water and Solid Waste for Development, at the Swiss Federal Institute of Aquatic Science and Technology (Eawag), where I have been working since 1998, first as tenure track researcher… Continue reading Christian Zurbrügg joins Kretsloppsteknik as Adjunct Professor
