1. 11. 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

3. 12. Frame Analysis in Environmental Conflicts : The case of ethanol production in Brazil

   Författare :Ester Galli; Ronald Wennersten; Tom Dwyer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; biodiversity; biofuel; CO2 emissions; environmental conflict; ethanol; frame; frame analysis; land use change; sugarcane; sugarcane cutters; sustainable energy;

   Sammanfattning : Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption.

4. 13. Systems Modeling Approaches to Physical Resource Management : An Industrial Ecology Perspective

   Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industrial Ecology; Industriell ekologi;

   Sammanfattning : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. LÄS MER

5. 14. Towards a pre-verified EPD tool with simulation capabilities for the aggregates industry

   Författare :Panagiota Papadopoulou; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EPD; pre-verified EPD tool; aggregates; process simulations; crushing plants; Plantsmith; LCA;

   Sammanfattning : Aggregates are an indispensable component in the development of societies as they are the basic materials for most buildings and infrastructure projects. Therefore, understanding and taking actions regarding their environmental impact is necessary for the industry’s sustainable development and climate neutrality. LÄS MER

7. 15. Organisational background to environmental impacts - Field study on housing management in Gothenburg

   Författare :Birgit Brunklaus; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; time series; housing management; organisational influence; organising; LCA; environmental performance.; consumption data; comparative study; field study; existing buildings;

   Sammanfattning : Today, there is a rich variety of technical solutions for environmental improvements of buildings. Nevertheless, the environmental performance of for example residential buildings has not been changed since the 1980s. Management initiative is needed for the introduction of technical solutions for environmental improvements. LÄS MER
