2. 1. 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

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. Biogas production from a systems analytical perspective

   Author : Maria Berglund; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; indirect environmental impact; fuel-cycle emissions; environmental systems analysis; energy systems analysis; energy balance; digestate; Anaerobic digestion; biogas;

   Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. READ MORE

6. 4. Design and development of a novel textile based bioreactor: : Ethanol and biogas production as case studies

   Author : Osagie Alex Osadolor; Christian Larroche; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; bioreactor; bioreactor design; techno-economic analysis; membrane stress analysis; mass transfer; hydrodynamics; Resource Recovery; Resursåtervinning;

   Abstract : Bioreactors are designed to provide enabling conditions for the controlled growth of microorganisms, such as good heat and mass transfer, aeration, hydrodynamics, geometry for adequate gas holdup, pH and foaming control, conditions for optimal substrate consumption and product formation, as well as mechanisms for monitoring microbial conditions. Additionally, bioreactors are designed to handle stress that would be exerted on them by the weight of the fermenting media and by the high pressure used for sterilisation. READ MORE

7. 5. Bioprocessing of Recalcitrant Substrates for Biogas Production

   Author : Maryam M Kabir; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; biogas; lignocellulose; wool; keratin; pre-treatment; co-digestion; dry digestion; economic evaluation; Resursåtervinning; Resource Recovery;

   Abstract : The application of anaerobic digestion (AD) as a sustainable waste management technology is growing worldwide, due to high energy prices as well as increasingly strict environmental regulations. The growth of the AD industry necessitates exploring new substrates for their utilisation in AD processes. READ MORE
