Novia University of Applied Sciences

Novia UAS in Vaasa, Finland is the lead partner in the STASIS project. Novia UAS has long experience working with boreal agricultural acid sulfate soils and testing mitigation strategies with different lime products and organic materials in both the laboratory and field. The persons working in the project, Eva Högfors-Rönnholm and Sten Engblom, bring a wide competence regarding soil microbiology and chemistry to the project. The objective is to inhibit the biogeochemical oxidation process in short-term stored excavated sulfide-rich soils as well as in dredged sulfide-rich sediments permanently used as e.g. agricultural land or earth embankments without negative impact on the environment.

In addition to coordinating the project, Eva participates in laboratory and field studies with short-term stored excavated sulfide-rich soils and dredged sulfide-rich sediments, and in cooperation with Linnaeus University investigates the microbiological aspects in the biogeochemical oxidation by identifying bacteria involved in the process through e.g. 16S rRNA gene sequencing. Sten coordinates laboratory and field studies with dredged sulfide-rich sediments, participates in studies with short-term stored excavated sulfide-rich soils, and investigates the chemical effects on the drainage water from the excavated and dredged materials.

Vaasa University of Applied Sciences

Vaasa UAS (VAMK) in Vaasa, Finland is a partner in the STASIS project. VAMK has long experience of working with boreal agricultural acid sulfate soils and testing mitigation strategies with different lime products and organic materials in both the laboratory and field. The person working in the project, Pekka Stén, brings a wide competence regarding chemistry and mineral technology to the project. The objective is to inhibit the biogeochemical oxidation process in dredged sulfide-rich sediments for them to be used as e.g. agricultural land or earth embankments without negative impact on the environment.

Pekka participates in the laboratory and field studies with dredged sulfide-rich sediments and investigates the chemical effects on the drainage water from dredged materials.

Dåva Deponi och Avfallscenter i Umeå AB

Dåva DAC is a landfill in Umeå, Sweden that has long experience of treating and depositing excavated materials rich in sulfide. The persons working in the project, Gustaf Sjölund, Jörgen Aronsson, Åsa Tykesson-Nilsson, and Christer Lindqvist bring a wide competence regarding the investigation and handling of sulfidic soils to the project, both in regards to chemical stabilization and environmentally safe deposition.

Gustaf, Jörgen, Åsa, and Christer all work at the Dåva landfill plant and will take part in the STASIS project's different WPs, mostly concerning pilot scale testing and contact with the Swedish stakeholders.

Luleå University of Technology

Luleå University of Technology in Luleå, Sweden is a partner in the STASIS project. Luleå University of Technology has long experience working with boreal sulfide-rich soils. The persons working in the project, Christian Maurice, Ida Kronsell, Alaleh Ziagharib, and Qi Jia, bring wide competence regarding the amelioration of the geotechnical properties of sulfide-rich soils and mitigation of acid leaching to the project. The objective is to reuse the upgraded soil in construction such as earth embankments and road slopes without negative impact on the environment.

Ida and Christian work on the chemical stabilization of the sulfide-rich soils in order to limit leaching from excavated soil and trenches. The needs for stabilization are sometimes time limited (prior to transport of the soil or temporary closing of the trench) while use in embankments requires a permanent solution.  Alaleh and Qi work with mechanical stabilization of soil to improve strength to allow construction in slopes and enhance recycling of soil.

Linnaeus University

Linnaeus University in Kalmar, Sweden is a partner in the STASIS project. Linnaeus University has long experience working with acid sulfate soils and other acidic and neutral low-temperate systems and landscapes in the boreal zone. The persons working in the project, Mark Dopson and Mats Åström and their PhD-students Anders Johnson and Alexandra Nyman, bring a wide competence regarding acidophilic microorganisms and geochemical processes to the project. The objective is to inhibit the biogeochemical oxidation process in short-term stored excavated sulfide-rich soils as well as in dredged sulfide-rich sediments permanently used as e.g. agricultural land or earth embankments without negative impact on the environment.

Mark and Anders participate in laboratory and field studies with short-term stored excavated sulfide-rich soils and dredged sulfide-rich sediments and investigates the microbiological aspects in the biogeochemical oxidation by identifying bacteria involved in the process through e.g. 16S rRNA gene sequencing and bioinformatic analyses. Mats and Alexandra participate in laboratory and field studies with short-term stored excavated sulfide-rich soils and dredged sulfide-rich sediments and investigates the geochemical aspects in the biogeochemical oxidation process.
