1. 6. Circular bioeconomy through valorisation of agro-industrial residues by the edible filamentous fungus Neurospora intermedia

   Författare :Rebecca Gmoser; Mohammad J Taherzadeh; José António Teixeira; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neurospora intermedia; mycoprotein; carotenoids; feed; solid-state fermentation; circular bioeconomy; Resource Recovery; Resursåtervinning;

   Sammanfattning : Prevention of dramatic climate change and ensuring food and nutrition security for subsequent generations necessitates the reduction of greenhouse gas emissions and efficient use of the world’s resources, including efficient waste disposal. The agro-industrial sector generates a large amount of organic waste, that is currently underexploited owing to poor waste management practices. LÄS MER

3. 7. Peat Coated with Iron Oxides : Purification of Metal(loid)-Contaminated Water and Treatment of the Spent Adsorbent

   Författare :Alfreda Kasiuliene; Jurate Kumpiene; Ivan Carabante; Prosun Bhattacharya; Luke Beesly; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron-peat; adsorption; arsenic; metals; combustion; hydrothermal carbonisation; landfilling; Avfallsteknik; Waste Science and Technology;

   Sammanfattning : In Sweden due to the industrial activities, such as wood impregnation, multiple point sources of arsenic (As) contamination in soil and water bodies are scattered over the country. Metals, such as chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), cadmium (Cd) or zinc (Zn) at varying concentrations are usually present as well. LÄS MER

4. 8. A long journey from bioanode to biocathode

   Författare :Soroush Saheb Alam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocathode; Bioelectrochemical system; Storage; Starvation; Microbial electrolysis cell; Bioanode; Microbial fuel cell; Mixed microbial communities; Hydrogenotrophic microorganisms;

   Sammanfattning : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. LÄS MER

5. 9. Sustainable recycling of Li-ion batteries

   Författare :Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

7. 10. Conditions for resource-efficient production of biofuels for transport in Sweden

   Författare :Carolina Ersson; Mats Eklund; Jonas Ammenberg; Mikael Lantz; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. LÄS MER
