  2. 11. Assessing Carbon Dioxide Removal methods amid uncertainty : soil carbon sequestration, biochar and harvested wood products as methods for climate change mitigation

    Author : Alexander Olsson; Stefan Grönkvist; Mathias Fridahl; Anders Hansson; Lowe Börjeson; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Removal CDR ; Negative Emissions Technologies NETs ; Soil Organic Carbon; Biochar; Harvested Wood Products HWP ; Socio-technical systems; Strategic Niche Management SNM ; Chemical Engineering; Kemiteknik;

    Abstract : Measures to sequester carbon dioxide (CO2) away from the atmosphere have become increasingly important in the discussion of which methods humans can employ to limit global warming. These measures, which are broad and varied, fall under the umbrella of Carbon Dioxide Removal (CDR) methods. READ MORE

  4. 12. Ecosystems in the Anthropocene: the role of cropland management for carbon and nitrogen cycle processes

    Author : Stefan Olin; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon; Nitrogen; DVM; Ecosystem modelling; Cropland; Management; Yields;

    Abstract : Through deforestation and conversion of natural ecosystems to croplands and pastures, have humans released vast amounts of carbon (C) dioxide (CO2) into the atmosphere. Roughly one third of the cumulative anthropogenic emissions until today stem from these practices, the remainder being mostly due to fossil fuel combustion. READ MORE

  5. 13. The Role of Carbon-Nitrogen Interactions for Terrestrial Ecosystem Dynamics under Global Change - a modelling perspective

    Author : David Wårlind; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-N Interactions; Ecosystem Modelling; DGVM; Nitrogen; Carbon; Climate Change;

    Abstract : The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it occurs, is a challenging task.

  6. 14. Sediment remediation using activated carbon: amending knowledge gaps

    Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE

  7. 15. Carbon Recovery in A Dual Fluidized Bed Gasifier

    Author : Sébastien Pissot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

    Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE
