6. Sustainable management of dredged sediments : potential recovery of valuable compounds
Sammanfattning : 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. LÄS MER
7. Biorefinery systems for energy and feed production : greenhouse gas performance and energy balances
Sammanfattning : The current dependence on fossil fuels is problematic because these are a finite resource and because their combustion causes environmental degradation. Biorefineries produce a variety of valuable products from biomass that can replace products from petroleum refineries. LÄS MER
8. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions
Sammanfattning : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. LÄS MER
9. Artificial neural networks : applications in morphometric and landscape features analysis
Sammanfattning : In this thesis a semi-automatic method is developed to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as a unsupervised Artificial Neural Network algorithm. Analysis and parameterization of topography into simple and homogenous land elements (landform) can play an important role as basic information in planning processes and environmental modeling.

10. Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy
Sammanfattning : The unsustainable levels of resource use and emissions of our economies and their threat to future generations are core issues of our time. The circular economy (CE) conceptualises a different type of economy that is restorative and regenerative by design and aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles.
