1. 6. Power to gas : Bridging renewable electricity to the transport sector

   Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

   Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER

3. 7. An evaluation of solar powered irrigation as carbon offset projects

   Författare :Alexander Olsson; Jinyue Yan; Björn Frostell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon offset; carbon sequestration; clean development mechanism; climate change adaptation; desertification; solar power water pumping; Chemical Engineering; Kemiteknik;

   Sammanfattning : Carbon offsets have been developed as one tool to incentivise investments by developed nations in climate change mitigation activities in developing countries. The carbon offsets can be used towards the countries’ own mitigation targets but are also meant to benefit developing countries by providing a pathway to clean development. LÄS MER

4. 8. Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

   Författare :Jagdeep Singh; Björn Frostell; Olga Kordas; Anju Singh; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industrial Ecology; Industriell ekologi;

   Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER

5. 9. Towards a Sustainable Resource Management : A Broader Systems Approach to Product Design and Waste Management

   Författare :Jagdeep Singh; Björn Frostell; William Hogland; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Resource Management; Product Design; Waste Management Challenges; Systems Thinking; Sustainability Science; Industrial Ecology; Industriell ekologi; Resource Management; Product Design; Waste Management Challenges; Systems Thinking; Sustainability Science;

   Sammanfattning : Rapid economic growth, urbanisation and increasing population have caused (materially intensive) resource consumption to increase, and consequently the release of large amounts of waste to the environment. Numerous technological and operational approaches to resource management have been introduced throughout the system of production, consumption and waste management. LÄS MER

7. 10. Industrial Ecology Approaches to Improve Metal Management : Three Modeling Experiments

   Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Amir Rashid; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system dynamics; element flow analysis; industrial ecology; product systems; end-of-life; DPSIR; pressure-based driver-oriented approach; environmental management; Industrial Ecology; Industriell ekologi;

   Sammanfattning : A linear model of consumption − produce-use-dispose − has constantly increased the pressure on the environment in recent decades. There has been a great belief that technology will solve the problem, but in many cases it is only partly contributing to the solution. For a full solution, the root causes of problems need to be identified. LÄS MER
