2. 6. On the optimal use of industrial-generated biomass residues for polygeneration

   Author : Marianne Salomón Popa; Torsten Fransson; Andrew Martin; Lasse Rosendahl; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Optimization; Palm Oil; Biomass; forest residues; Colombia; Sweden;

   Abstract : Increasing energy demand as well as climate change concerns call for an analysis and optimization of energy services. Efficient use of energy resources, mitigation of environmental effects and supply an increasing demand are just some of the issues that are relevant nowadays in the energy system. READ MORE

4. 7. Communication of life cycle assessment results : life cycle key performance indicators

   Author : Helena Nydahl; Thomas Olofsson; Anders P. Åstrand; Staffan Andersson; Åsa Wahlström; Umeå universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Monetary Valuation; Climate Impact; Life Cycle Key Performance Indicators; Global Warming Potential; LCA-result communication; Interpretation of LCA-results; climate change; klimatförändringar;

   Abstract : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. READ MORE
