  2. 1. Energy Efficiency in Machine Learning : Approaches to Sustainable Data Stream Mining

    Author : Eva García Martín; Håkan Grahn; Veselka Boeva; Emiliano Casalicchio; Jesse Read; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; machine learning; energy efficiency; data stream mining; green machine learning; edge computing; Computer Science; Datavetenskap;

    Abstract : Energy efficiency in machine learning explores how to build machine learning algorithms and models with low computational and power requirements. Although energy consumption is starting to gain interest in the field of machine learning, still the majority of solutions focus on obtaining the highest predictive accuracy, without a clear focus on sustainability.

  5. 3. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry

    Author : Katerina Hruzova; Ulrika Rova; Saija Luukkanen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organosolv lignin particles; Nanoparticles; Flotation reagent; Copper recovery; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. READ MORE

  6. 4. Sustainable management of dredged sediments : potential recovery of valuable compounds

    Author : Laura Ferrans; William Hogland; Monica Odlare; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dredged sediments; nutrients; metals; speciation; recovery; characterisation; beneficial use; life cycle assessment; extraction; plant-growing substrate; circular economy; Miljövetenskap; Environmental Science;

    Abstract : Dredging of sediments occurs worldwide to increase water depth in harbours, bays, lakes and rivers, as well as to recover aquatic ecosystems. Landfilling and open-ocean discharge are traditional disposal routes for dredged material. However, the methods are restricted by environmental and legal concerns. READ MORE

  7. 5. Source, mobility and fate of critical Be, Bi, F and W from historical sulfidic-oxidic skarn tailings : Re-mining as remediation method?

    Author : Lina Hällström; Lena Alakangas; Olof Martinsson; Heather Jamieson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

    Abstract : There is a potential risk that geochemical cycles of several critical metals will be affected in the pristine environment, when mining of these metals increases to meet the demand in green technology. The identification of critical metals is based on the economic importance and vulnerability to supply restrictions. READ MORE
