Molecular Methods course in Finland

Jenna Senecal attended a course on Molecular Methods for Detection of Food- and Waterborne Pathogens in Helsinki, Finland (04.03.2018-08.03.2018). The course was taught and attended by top researchers  from the Nordic countries. She learned about the latest available technologies for DNA extraction and analyses being used for detecting pathogenic strains of viruses, bacteria and parasites.

SPANS project work in Uganda

There is a lot going in the SPANS project in Uganda right now.

We have started demonstration units of nutrient-recovery treatment technologies for fecal sludge at the Luibgi wastewater treatment plant in Kampala. Two MSc students from Luleå University of Technology are currently operating demonstration units for treatment with lime and urea.  The students are collecting and analyzing samples to determine if the technologies are functioning properly with regard to reduction of public and environmental health risks. They are also doing interviews with workers at the wastewater treatment plant and other stakeholders to understand the levels of acceptance and feasibility of implementing such technologies within the existing management structures. Soon two students from Makerere University will be starting a demonstration unit with Black Soldier Fly composting at the wastewater treatment plant.

Sanitation Round Table meeting in Nairobi, Kenya

SLU and IAS (International Aid services) jointly hosted a round table meeting on the 25th of January in Nairobi, Kenya. Different stakeholders such as local politicians, NGOs and researchers took part in the meeting, to discuss how to jointly solve the sanitation situation in Africa’s largest urban slum, Nairobi’s Kibera.

Datum: 14/3-2018, 9 – 16
Plats: Ultuna campus (Biosfären och Flugväxthuset), Uppsala
Pris: 5000 kr/person

Under denna endagsutbildning ger vi dig som deltagare en övergripande introduktion till fluglarvskompostering och flugodling. Vi går igenom teorin i de olika stegen i modulbaserad fluglarvskompostering och därtill hörande storskalig flugodling följt av praktiska övningar i hantering av larver, puppor och flugor. Kursen kommer till stora delar att vara på engelska. Vid internationellt deltagande kommer hela kursen att hållas på engelska.

Kandidatpresentation: Växthusgasutsläpp från fluglarvskompostering

English version below.

Frida Erlöv kommer att hålla sin kandidatpresentation om växthusgasutsläpp från fluglarvskompostering 22 Februari kl 14 i Ekoln. Håkan Jönsson är examinator.

Referat

Fluglarvskompostering med den Amerikanska vapenflugan (Hermetia illucens) har visat sig vara en effektiv behandlingsmetod som genererar flera produkter av värde, såsom djurfoder och organiskt gödningsmedel eller biobränslen. Behandling med larver av den Amerikanska vapenflugan har därmed potentialen att bidra till en miljömässigt positiv och ekonomiskt lönsam återvinning av de biologiska restprodukter som finns i vårt samhälle. Syftet med denna studie var att undersöka växthusgasutsläpp från fluglarvskompostering samt jämföra dessa med aerob termofil kompostering. Detta för att i senare studier kunna bedöma den totala miljöpåverkan av fluglarvskompostering. För att uppnå detta mättes gasutsläpp från tre olika fluglarvskomposteringsbehandlingar: en med endast fluglarver och två där det även tillsattes nedbrytande fluglarvsspecifika bakterier utöver själva fluglarverna. Utöver gasutsläpp mättes även olika parametrar i materialet (pH, skrymdensitet, kompostmognad, vattenhalt, glödförlust och total kväve) för att kunna jämföra de olika behandlingarna och för att få en ökad förståelse för de processer som ägt rum.

Professor Håkan Jönsson får Vatten-priset

On March 14th, Professor Håkan Jönsson will be awarded the Water Prize by Föreningen Vatten (Society Water). ”Never during my 10 years in the board of Föreningen Vatten have we received so many heavy nominations for a certain person. 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’.

Lessons learnt towards sustainable resource loops, and remaining challenges

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 thanksPost published by Prithvi Simha

 

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 presentationPost published by Prithvi Simha
