Björn was invited as Sweden’s representative in the Vietnames Agritech conference during the 28th of November. The title of his talk was technical solutions in relation to “Challenges in Post-Covid Environment for Agriculture Sector”. His focus of the presentation and the panel discussion was that the circular economy can reduce the pollution of the environment as we remove the nutrients from the linear flow of today. At the same time do we increase the resilience in the agriculture as we can replace up to half of the imported mineral fertilisers with local waste and wastewater generated fertilisers. The new Covid era gives new opportunities for global collaboration and knowledge sharing over the internet.

The panel discussion about the effect of Covid 19 upon food production and agriculture.

I september mÄnad tog kretsloppsgruppen emot ett studiebesök frÄn masterstudenter pÄ programmet HÄllbara livsmedelssystem. I kursen Prospects and challanges for sustainable food systems, som hÄlls av Pernilla TidÄker, universitetslektor vid institutionen för energi och teknik, ingÄr ett par förelÀsningar om kÀllsorterande avloppssystem och Ätervinning av nÀringsÀmnen och i dessa förelÀsningar bakades studiebesöket in.

Victoria Wiklicky, forskningsassistent, gav en introduktion till fluglarvskompostering, Caroline Karlsson, ocksÄ forskningsassistent, pratade om kÀllsorterande avloppssystem och urintorkning och Annika Nordin, forskare, visade och berÀttade om kretsloppsgruppens innovativa avloppslösningar.

Studiebesöket hölls utomhus i linje med covid-19-restriktionerna. Studenterna fick cirkulera mellan de tre stationerna, lyssna och diskutera de olika forskningsomrÄdena. De fick Àven (med avstÄnd) följa med upp och titta pÄ Energi och tekniks urinsorterande toalett och urintork.

Study visit from Sustainable Food Systems

In September, the environmental engineering group received a study visit from students in the Sustainable Food Systems master program. The course Prospects and challenges for sustainable food systems, held by Pernilla TidĂ„ker who is a senior lecturer at the Department of Energy and Technology, includes a couple of lectures on source separation of waste water and the concept of nutrient recycling. Victoria Wiklicky, research assistant, gave an introduction to fly larvae composting; Caroline Karlsson, also research assistant, talked about source-separation of waste water and urine drying and Annika Nordin, researcher, showed and talked about the environmental engineering group’s innovative waste water treatment solutions. The study visit was held outdoors in accordance with the covid-19 restrictions, the students circulated between the three stations, listened to and discussed the different research topics. They also got to pay a visit (at safe distance) to the urine diverting toilet and drying system at the department of Energy and Technology.

We developed a simple process to recycle urine. Here’s how it’s done in 10 Steps

Every year on November 19, the United Nations celebrates one of public health’s greatest inventions – the toilet. Those who are fortunate enough to have access to one spend more than a year of their lives on it, yet millions of people worldwide cannot use one and many have never even seen one.

Invented back in 1775, the flush toilet has changed surprisingly little in design. In fact, a toilet is nothing more than a seat (or a pan) connected to a pipe with a bend. If this pipe is further connected to a system of sewers that carries away excreta to a centralised treatment plant, then wastewater can safely be discharged into the environment.

Anaerob nedbrytning appliceras i stor utstrÀckning pÄ avloppsslam och andra organiska rester för att stabilisera substratet och fÄnga upp nÄgot av dess energivÀrde via produktion av biogas. Genom att kombinera anaerob nedbrytning med nÀringsteknologier kan bÄde energi och nÀringsÀmnen Ätervinnas. StruvitutfÀllning och ammoniakstrippning Àr tvÄ av de mest mogna teknikerna för att utvinna fosfor och kvÀve frÄn strömmar, sÄsom vÀtskefraktionen av anaerobt matsmÀltningsmedel. Men hur effektiva Àr dessa tvÄ processer nÀr det gÀller nÀringsÄtervinning?

Phosphorus and nitrogen recovery from anaerobic digestate – how effective is it?

Published
By

Anaerobic digestion is widely applied to sewage sludge and other organic residuals to stabilize the substrate and capture some of its energetic value via the production of biogas. By combining anaerobic digestion with nutrient recovery technologies, both energy and nutrients could be recovered. Struvite precipitation and ammonia stripping are two of the most mature technologies to recover phosphorus and nitrogen from streams such as the liquid fraction of anaerobic digestate. But how effective are these two processes in terms of nutrient recovery?

On 24 October every year, UN Day is celebrated and this year marked the anniversary of UN’s 75th anniversary. This year, Swedish high schools worked with the UN’s global goals and Malmö latinskola had chosen goal 6 – clean water and sanitation – and goal 14 – life below water. Caroline Karlsson, research assistant in the environmental engineering group; Jens Olsson, researcher at the Department of Aquatic Resources; and Helena Aronsson, senior lecturer at the Department of Soil and Environment, were invited to give lectures on these themes for a class of first-year students.
