2. 1. Biogas from slaughterhouse waste : Mixtures interactions in co-digestion

   Author : Jhosané Pagés Diaz; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slaughterhouse waste; Agro-Waste; Co-digestion; Synergistic effects; Methanogenic community structure; Resource Recovery; Resursåtervinning;

   Abstract : Global environmental concerns connected to the use of fossil fuels have forced the development ofalternative sustainable energy technologies. The application of anaerobic digestion, from waste streams thatcurrently have no use, can be utilized for bioenergy production. READ MORE

4. 2. Biogas Production from Lignocelluloses : Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

   Author : Anna Teghammar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology;

   Abstract : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. READ MORE

5. 3. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

   Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

   Abstract : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. READ MORE

6. 4. Waste Textiles Bioprocessing to Ethanol and Biogas

   Author : Azam Jeihanipour; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

   Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

7. 5. Recovery of organic carbon from municipal waste streams

   Author : Isaac Owusu-Agyeman; Elzbieta Plaza; Zeynep Cetecioglu; Irini Angelidaki; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Volatile fatty acid; Anaerobic granules; Co-digestion; Municipal waste; Chemical Engineering; Kemiteknik;

   Abstract : The focus of the current study was on the recovery of carbon from municipal bio-waste streams. Firstly, the relationship between methanogenic pathways and the properties of anaerobic granules was studied using two pilot-scale upflow anaerobic sludge blanket (UASB) reactors with different granule size distribution.
