1. 1. 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

3. 2. Strategic Life-Cycle Modeling and Simulation for Sustainable Product Innovation

   Författare :Henrik Ny; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable product innovation; planning; strategy; backcasting; life-cycle assessment LCA ; strategic life-cycle management SLCM ; systems; modeling; simulation;

   Sammanfattning : Many specific methods and tools have been developed to deal with sustainability problems. However, without a unifying theory it is unclear how these relate to each other and how they can be used strategically. A Framework for Strategic Sustainable Development (FSSD) is being developed to cover this need for clarity and structure. LÄS MER

4. 3. Environmental Assessment of Emerging Routes to Biomass Based Chemicals The Case of Ethylene

   Författare :Christin Liptow; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; sugarcane; time lags; gasification; biomass based chemicals; wood; land use; life cycle assessment; ethylene; LCA;

   Sammanfattning : The production of bulk chemicals from biomass instead of fossil resources is perceived as one promising option to decrease society's environmental impact. However, though considerable research and development efforts aim at such production, it might take several more years before biomass based bulk chemicals are fully commercialized. LÄS MER

5. 4. The green engineer as an enabler of life-cycle management in manufacturing: models and practices

   Författare :Birger Löfgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete-event simulation; life-cycle assessment; operation management; decision making; practice studies; environmental management;

   Sammanfattning : The last 20 years corporate environmental management has developed from pollution control and emission prevention, to include a greater responsibility for indirect environmental issues along the whole product life cycle. This thesis aims at providing a better understanding of how such environmental life-cycle management can be applied on manufacturing processes. LÄS MER

7. 5. Life cycle assessment of renewable-based hydrocarbon plastics

   Författare :Christin Liptow; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; renewable LDPE; biomass-based plastics; simplified LCA for conventional; LCA and process simulation;

   Sammanfattning : Plastics are an important commodity of our daily life. And although their majority is still based on fossil feedstocks, numerous efforts are made to stem the environmental consequences related to their production. One approach is the use of renewable materials (biomass) to produce today’s conventional plastics. LÄS MER
