Our one-day-course in modular fly larva treatment is in high demand. After the first course opportunity in December 2017, the course was organized again on 14 March 2018, with eight participants from different Swedish companies and universities.

In the morning Cecilia Lalander and Evgheni Ermolaev gave an in-depth introduction to the concept of a modular system developed at SLU and presented the possibilities on waste management with the black soldier fly larvae. Details on both the fly rearing and waste treatment modules were presented.

Research-Policy Interaction for Sustainable Development

Prithvi Simha, PhD student at the Kretsloppsteknik group attended a course on research-policy interaction at the Gothenburg Centre for Sustainable Development (GMV). The course was given as part of the ‘Water Research School‘ for PhD students in Sweden, of which several candidates from our group are part of. The course involved creating a research-to-policy plan related to Prithvi’s PhD research on urine dehydration, understanding models for stakoholder interaction and learning to effectively communicate with policymakers. Course participants also got to hear from Johan Kuylenstierna, former CEO of Stockholm Environmental Institute, on his personal experiences of science-policy interaction.

Location: Campus Ultuna (Biosfären och Flugväxthuset), Uppsala
Price: 5000 SEK/person

Under this one-day course the course delegates will be presented with a general introduction to fly larvae treatment, including both the fly rearing and composting steps. We will present the theory behind the different steps of the module based fly larvae treatment and practical exercises on handling of larvae, pupae and flies. The course will be given in English.

Frida Erlöv will present her Bachelor thesis about Greenhouse gas emissions from fly larvae composting on 22 February at 2 pm in Ekoln. Håkan Jönsson is the examinor. The presentation will be held in Swedish.

Abstract

Black soldier fly (Hermetia illucens) composting have proven to be very effective in degradation of organic waste products, while generating valuable products, such as animal feed and organic fertilizers or biofuels. Treatment with black soldier fly larvae has thereby a potential to contribute to a more environmental friendly and economically viable management of biological waste fractions. The aim of this study was to measure greenhouse gas emissions from black soldier fly composting and to compare these with emissions from thermophilic aerobic composting. Gas emissions from three different black soldier fly larvae composts were measured: one with only larvae and two in which specific fly larvae bacteria were added as well as the larvae. In addition, various parameters (pH, bulk density, compost maturity, total solids, organic content and total-N) were measured, to get a better understanding concerning present processes.

Most universities, organizations and individuals in the industry have shown strong support for this prize winner“, writes Marta Ahlquist-Juhlén, the chairman of Föreningen Vatten. Among others, Prof. Jönsson has actively worked to close the cycle between cities and rural areas for 25 years, and his research has made a great impression. Most well-known is his commitment to upstream solutions in wastewater systems and his work on recycling plant nutrients from wastewater to arable land.

The Future in Sanitation is off the grid!

How much water do each of us use every day? Can future sanitation systems and off-the-grid houses be designed so as to minimize energy and water consumption? Where does wastewater management fit into the waste hierarchy/pyramid? In his presentation, Björn Vinnerås, Associate Professor at SLU shares with us his vision of future housing: a future where there is ‘no need for network connections, neither electricity nor water, and nor wastewater’.

On 25th October, the kretsloppsteknik research group hosted a farewell symposium in honor of Professor Håkan Jönsson. At SLU, Prof. Jönsson has been leading research and education on the topic of nutrient recycling from wastewater and food waste since 1993, when the topic was first introduced at the department of energy and technology. It was under his lead, the research group kretsloppsteknik (environmental engineering) was established.

In his farewell presentation Prof. Jönsson explored many topics such as composting, source-separation of wastewater, urine diversion and recycling, systems analysis and environmental impact assessment of urine diversion, etc. Click here to access the presentation which recaps the work, research and contributions of Prof. Jönsson to various subject areas over the years.

Prof. Jönsson closed the symposium with further remarks and a vote of thanks.

The Future of Sanitation Education

At a symposium hosted by the Kretsloppsteknik group, Dr. Mariska Ronteltap of the IHE Delft Institute for Water Capacity Building presented her perspective on what the future of sanitation education could look like. Why is it important to build capacity in the WASH sector? How can we do it through innovative teaching methods? How can MOOCs, Online Learning, Professional Diploma Programs, Active Learning, etc. towards sanitation education? Learn about this and the one-year Masters Programme in Sanitation being developed by IHE in Dr. Ronteltap’s presentation.
