Workshop on system analysis of sludge biochar systems
On Monday, 25 September, Testbed Ellinge organised a digital workshop on system analysis of sludge biochar systems. Four different research groups, from Denmark, Finland, Norway and Sweden respectively, participated.
How plant available is the phosphorus in the sludge biochar?
Thursday 21 September, we had a pre-meeting for the project Phosphorus availability in sludge and sludge biochar, in which we will study phosphorus and heavy metal uptake in a four-year frame study. Dorette Müller-Stöver and Jakob Magid visited VA SYD and Testbed Ellinge's project manager David Gustavsson yesterday to discuss the project.
Final conference for the Rest till Bäst project
A range of results were presented at the project Rest till Bäst final conference in Malmö last week.
The pilot is now being assembled at Ellinge WWTP
Now all the parts for the pilot are in place at Ellinge.
FramBliK – a new pilot project at Källby Wastewater Treatment Plant
In August, a new pilot for effective biological phosphorus and nitrogen removal was started at the Källby Wastewater Treatment Plant (WWTP). The project is called FramBliK, an Swedish acronym for “The biofilm process of the future in continuous operation”.
How does the pretreatment of wastewater affect the energy balance …
... and the need for volume for the biological treatment?
The 2nd Swedish Conference on Sewage Sludge Biochar 2024
It's time to make space in your calendar for the 2nd Swedish Conference on Sewage Sludge Biochar, 15-17 October 2024.
New report on the city’s sources of microplastics
Emma Fältström, a PhD student at Sweden Water Research, and Heléne Österlund at Luleå University of Technology have in their report “μrban Plastics – Sources, sinks and flows of microplastics in the urban environment” mapped out how microplastics from land enter our water environments, with a focus on stormwater.
Pilot plant at Ellinge WWTP is further delayed
The startup of the pilot plant at Ellinge Wastewater Treatment Plant (WWTP) is further delayed. The first batches of sludge will be pyrolyzed in October instead of August as previously planned. The supplier, Aquagreen, will be on-site until December to fine-tune the facility.
Testbed Ellinge presented at the Biochar Summit 2023
At the Biochar Summit 2023 in Helsingborg, during the Sewage Sludge Pyrolysis in the FPR workshop, several researchers presented their work on sewage sludge biochar. One of them was the project leader of Testbädd Ellinge. Here is a brief summary.
ICU – improved carbon utilization in a smaller footprint
In the research project ICU, industrial PhD student Elin Ossiansson is testing a new process combination for more efficient wastewater treatment, aiming to generate an equal amount of biogas from the sludge but with reduced energy consumption. After two years of pilot testing at the Källby wastewater treatment plant, the results are promising.
Testbed Ellinge represented when waste was in new focus
In March, people interested in waste gathered from all corners of Sweden in Gothenburg for the conference Waste in New Focus. During the session that dealt with attitudes and potentials around sludge recycling, Dag Lorick participated and told about Gryaab's view on pyrolysis and about the work carried out in Testbed Ellinge.
