    Keywords : Wild boars; soil processes; tree growth; Vildsvin; markprocesser; trädtillväxt;

    Abstract : Wild boars (Sus scrofa) have increased rapidly in population size and home range since their reintroduction to the Swedish fauna. Through their rooting behaviour, the boars can cause great disturbance to the ecosystem. READ MORE

  3. 8. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Louise Hjalmarsson; [2021]
    Keywords : hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

    Abstract : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. READ MORE

For instance, it could be converted into biochar, which is proven to have many environmental benefits. READ MORE

  5. 10. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexis Cazorla; [2020]
    Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

    Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.
