Docent Jennifer McConville, at the Department of Energy and Technology, is one of the five researchers who has been awarded 3 million SEK as a career grant from the Vice-Chancellor of SLU.
SLU’s Career Grant is launched every second year to award researchers at the early stage of their careers. They receive a grant of 3 million SEK each. Jennifer McConville’s research uses systematic and applied sustainability analysis as decision support in planning and decision-making regarding sanitation and wastewater management. The aim is to improve resource recovery from these systems by adapting technical infrastructure and institutional arrangements. She performs her research in Sweden as well as low- and middle-income countries. She uses life cycle thinking, participation and socio-technical analysis to better understand and shape planning processes so that they can transition towards sustainability.
Jennifer McConville plans to use the career grant together with her research group to:
Develop and apply new transdisciplinary methods for sustainability analysis with a focus on resource recovery
Increase knowledge of trade-offs between different sustainability aspects
Develop guidance for transitioning to sanitation systems with increased resource efficiency and equitable access for all
The results of Jennifer McConville’s research will help authorities responsible for sanitation and wastewater management to increase resource recovery and choose more sustainable systems.
Research and development of circular nutrient technologies has intensified over the past years, making research output in this field increasingly hard to navigate and keep track of. There is a need for a robust and comprehensive mapping and synthesis of existing relevant research and better brokering of knowledge to policy and practice.
Researchers at our group are involved in the collaborative project End-of-wastewater that aims to:
Collate available peer-reviewed English language research on nutrient recovery and reuse into a comprehensive evidence base using systematic mapping methodology.
Develop an online evidence platform to navigate relevant scientific papers with ease.

As BSF has become mainstream as an exciting way to treat organic waste, we receive more and more inquiries with questions on “what shall I” and “how shall I”. Academic journal articles seldom give enough easily digestible answers for practitioners, interested in starting or already operating a BSF facility.
For this purpose a practical knowledge hub webpage has been established which contains information all around BSF waste processing in a hopefully easy and practical format for people “in the field”.
At the end of April all new professors at SLU were having their installation lectures. A totally new concept with online lectures and the audience could ask questions online. Björn gave his lecture with focus on how we in the future can decrease the emissions to the environment by disconnecting us from the water and wastewater system and instead use the same water in the house by cleaning and reusing it at the same time as we produce a clean fertiliser out of the toilet fraction. In total 147 people were attending the lecture. It is still possible to follow the lecture at the following link: https://youtu.be/EYtuP0ino3M?t=15148
Containing substantial amounts of plant nutrients, black soldier fly larvae frass or “BSF residue”, is a promising soil amendment that gains more and more interest with increasing BSF farming around the globe. In the last years, the residue at our BSF colony, accumulating from various chicken and fish feed experiments, was an overlooked ”by-product”. Most of the residue ended up in our own garden plots or worse, was sent off for incineration. As the 2021 garden-season kicked off, the BSF group teamed up with Ultuna Permaculture to put 500 kg of BSF residue to good use! Last month, the garlics received their first load of extra nutrients and once the weather starts to warm up, the potatoes are next. Our vision is to create a closed loop system in which we feed our fly larvae with locally sourced waste (such as bread or vegetable waste from nearby factories), generate protein in form of larval biomass and put the residue from the process back into the food chain.
Over the past years, research on technologies to recover nutrients from human excreta and domestic wastewater has intensified to such an extent that it has become difficult even for researchers in the field to keep track of new developments. In 2019, Harder and colleagues published a paper in Critical Reviews in Environmental Science and Technology that aimed to provide a synthesis of available and proposed nutrient recovery pathways, covering both processes and products rendered by treatment.
