   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digitalisation; environmental impact; Industry 4.0; manufacturing; sustainability;

   Abstract : Manufacturing companies are striving to improve productivity and reduce the environmental impacts of their activities. Meanwhile, digitalisation plays an important role in increasing productivity and has a profound impact on the environment of manufacturing systems. READ MORE

4. 7. Biodiversity in environmental assessment : tools for impact prediction

   Author : Mikael Gontier; Berit Balfors; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Environmental impact assessment; Strategic environmental assessment; Biodiversity assessment; Prediction tools; GIS; GIS-base ecological models; Miljöteknik; Environmental engineering; Miljöteknik;

   Abstract : Urbanisation and infrastructure developments impact on the surrounding natural environment and threaten biodiversity. The fragmentation of natural habitats in particular is a major obstacle for the preservation of biodiversity in a long-term perspective. READ MORE

5. 8. Towards sustainable shipping: Evaluating the environmental impact of electrofuels

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental assessment; LCA; emerging technology; marine fuels; human health; future fuel; sustainable shipping; carbon utilization; power-to-x; carbon capture;

   Abstract : The global, local, and regional environment is under pressure from human activity. Changes in the environment can be beneficial and strived for, but environmental and health problems need to be considered when we design human activities. READ MORE

6. 9. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

   Author : Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

   Abstract : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. READ MORE

7. 10. Chemical substitution with a life cycle perspective: The case of per- and polyfluoroalkyl substances in durable water repellents

   Author : Hanna Holmquist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LCIA; CAA; LCA; PFAS; DWR;

   Abstract : The aim of the research presented in this thesis was to support the process of substitution of side-chain fluorinated polymers in durable water repellents (DWRs), that give rise to emissions of hazardous per- and polyfluoroalkyl substances (PFASs). The focus was on: i) the provision of improved decision support regarding the environmental and human health performance of alternatives, and ii) public readiness for substitution and what messages can motivate consumers to voluntary substitution.
