In the past 2 years, the environmental engineering group has been collaborating with the waste management company of Eskilstuna in order to treat food waste with black soldier fly larvae. This technology, developed within the group over the past 10 years, aims to recover the nutrients present in organic waste streams and reintroduce them into… Continue reading 1-2 tons food waste treated by BSF composting in Eskilstuna

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 that’s where we came into the picture. On the… Continue reading Kretsloppsteknik at the Human Nature arranged by Axfoundation

On the 12th of March we had a visit from our colleagues at the Norwegian Institute of Bioeconomy Research (NIBIO). On the visit came Trond Mæhlum, Bente Føreid, Thorsten Heidorn and Anders Enoksen. From our group Björn Vinnerås, Jennifer McConville and Cecilia Lalander joined. We presented about our different ongoing projects on safe nutrient recycling:… Continue reading Visit from our dear neighbours

Just at the end of January, Kristina Lundgren presented her master thesis at Uppsala University. The aim of the thesis was to increase the understanding of how bacteria may affect fly larvae composting with the black soldier fly. The results showed no significant impact on the survival, final biomass or reduction of substrate when bacteria… Continue reading Kristina Lundgren, M.Sc. thesis on pretreatments in BSF composting

Every day, greenhouse gases leak out to the atmosphere around the world, which has a negative impact on the climate. These leakages occur, among other things, from poorly managed and unplanned landfills where a lot of the organic waste ends up. What can be done to get something out of value from organic waste and… Continue reading Lovisa Lindberg, M.Sc. Emissions of greenhouse gases and ammonia during fly larvae composting

As part of the result of the Vinnova financed project Five tonnes of fishes in different dishes that aims at producing fish reared exclusively on Swedish produced feed, fish reared on insect based protein were tested and evaluated against fish reared on conventional fish feed. The protein in the test feed comprised of a 1:1… Continue reading Insects fed on waste as fish feed

In our study just published in Journal of Cleaner Production  we were interested in finding out what how the larval feedstock affect the efficiency of the black soldier fly larvae (BSFL) composting process in terms of biomass conversion ratio, larval development and larval survival. We compared the process efficiency of nine different feedstocks and two… Continue reading What larvae need
