We were at the Hashemite University in Jordan last week, teaching a group of young students how we can safely recycle different household waste fractions. As part of this week-long course, we organised a day of interactive seminars and a role playing game to improve awareness among the students about the psychology, decision making, and… Continue reading Social aspects of recycling household wastes: perspectives from Jordan

Robert Almqvist joins kretsloppsteknik for his master’s project
Hi, my name is Robert Almqvist and I am writing my master thesis in Biology at the institution of energy and technology. I am a soil/plant-agricultural program student matriculated at SLU Uppsala since 2014. In my master thesis, I will look at fly larvae composting and at the possible effect different pre-treatments has on amino acid… Continue reading Robert Almqvist joins kretsloppsteknik for his master’s project
Teaching students in Jordan about safe nutrient recycling
This week, we (Sahar Dalahmeh, Mikael Pell, Annika Nordin, Cecilia Lalander, and Prithvi Simha) are in Jordan, conducting a 1-week course on recycling of various household waste fractions. The course is given at the Hashemite University, located about 50 km away from the capital city Amman. A group of about 20 very enthusiastic and inquistive… Continue reading Teaching students in Jordan about safe nutrient recycling
Cecilia Lalander from our group is about to give her Docent Lecture!
Date: 30/9 – 2019 | Time: 10:30 | Location: Room L, Main University building (Ulls hus), Ultuna campus Is biodegradable waste a problem or a resource? Some claim it’s a resource that can be managed in a much more efficient way, but how come it isn’t? How could a more efficient management look like? If… Continue reading Cecilia Lalander from our group is about to give her Docent Lecture!
Moisture content affects greenhouse gas emissions from thermophilic food waste composting
The effects of moisture on thermophilic composting process are investigated in the latest paper published in the Journal of Cleaner Production: https://doi.org/10.1016/j.jclepro.2019.118165 It is known that too wet active composts can cause excessive methane (CH4) emissions, but there is no consensus on how much and what exactly the rate of this change is with changing… Continue reading Moisture content affects greenhouse gas emissions from thermophilic food waste composting
Modeling large-scale Eskilstuna pilot fly larvae composting system
A study “Model selection for waste conversion efficiency and energy demands in a pilot for large-scale larvae treatment” was presented at the 60th International Conference of Scandinavian Simulation Society, SIMS 2019, in Västerås, Sweden. The study evaluated some technical aspects associated with larvae growth, ventilation and drying demands in a pilot sized black soldier fly… Continue reading Modeling large-scale Eskilstuna pilot fly larvae composting system
Greenhouse gas emissions from small-scale fly larvae composting
A new paper evaluating the greenhouse gas (GHG) emissions from small-scale fly larvae composting is published. The full paper is available here: https://doi.org/10.1016/j.wasman.2019.07.011 The aim of the study was to evaluate GHG and ammonia (NH3) emissions from fly larvae composting treatment of food waste and the effects of pre-treatment and seeding of the food waste… Continue reading Greenhouse gas emissions from small-scale fly larvae composting
Insecta Conference, Potsdam 5-6 September
On the 5th and 6th of September Giulio attended to the Isecta conference in Potzdam (Germany). The conference gave valuable insights and the latest finding on the topic of insects for food and feed covering several aspects of the sector, from the legislation point of view to basic research and optimisation of rearing systems. At… Continue reading Insecta Conference, Potsdam 5-6 September
Fly larvae composting research presented at Matologi
Evgheni Ermolaev and Nils Ewald from SLU Kretsloppsteknik together with Vesa Hiltula and Benny Björk from Eskilstuna Strängnäs Energi och Miljö AB presented the latest research results and the large-scale implementation progress of the fly lave composting system developed in the group from 2011. Matology is a yearly exhibition held by SLU in Stockholm with… Continue reading Fly larvae composting research presented at Matologi
The FAT larva – a future feed for animals?
In the last week of May, SLU was arranging the “Thesis Day”-event for the second year in a row. This was an opportunity for bachelor’s and master’s students to present their degree projects in the form of scientific posters. Six students were also chosen to arrange oral presentations of their projects. Nils Ewald was one… Continue reading The FAT larva – a future feed for animals?
