2. 1. Recycling of concrete in new structural concrete

   Author : Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

   Abstract : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. READ MORE

4. 2. Circularity in Thermal Recycling for Sustainable Carbon Fibers

   Author : Marina Corvo Alguacil; Roberts Joffe; Tommy Öman; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; carbon fiber; composites recycling; CFRP; polymer composites; sustainability; Polymeric Composite Materials; Polymera kompositmaterial;

   Abstract : The research field of composite materials is particularly fascinating due to the design freedom they offer and the infinite number of constituent combinations, including those that are already explored, and many more that are yet to be tried. One composite material that holds great potential contains carbon in its fiber shape. READ MORE

5. 3. Life cycle primary energy use and carbon emission of residential buildings

   Author : Ambrose Dodoo; Leif Gustavsson; Svend Svendsen; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggteknik;

   Abstract : In this thesis, the primary energy use and carbon emissions of residential buildings are studied using a system analysis methodology with a life cycle perspective. The analysis includes production, operation, retrofitting and end-of-life phases and encompasses the entire natural resource chain. READ MORE

6. 4. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

   Author : Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

   Abstract : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. READ MORE

7. 5. Life cycle assessment of bridges, model development and case studies

   Author : Guangli Du; Raid Karoumi; Håkan Sundquist; Gervásio Helena dos Santos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable construction; Life cycle assessment; LCA; Global warming; Bridge LCA; CO2 emissions; Cumulative energy demand; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : In recent decades, the environmental issues from the construction sector have attracted increasing attention from both the public and authorities. Notably, the bridge construction is responsible for considerable amount of energy and raw material consumptions. READ MORE
