2. 1. Biogas from agricultural waste : Turning unavailable residues into accessible resources

   Author : Mirjam Victorin; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Straw; Manure; Pretreatment; Process design;

   Abstract : Moving from a fossil dependent to a fossil free economy requires increased energy production from renewable resources. This thesis discusses the utilization of agricultural waste streams, such as straw and manure, for biogas production. READ MORE

4. 2. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas

   Author : Betty Mbatia; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; by-products; value addition; EPA; DHA; PUFA; biogas;

   Abstract : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.

5. 3. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production

   Author : Valentine Nkemka; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam pretreatment; dry digestion; biogas; biohydrogen; Caldicellulosiruptor saccharolyticus; cadmium; anaerobic digestion;

   Abstract : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). READ MORE

6. 4. From Waste to Wealth: Transforming Biorefineries into Platforms to Valorize Low-Quality Residues

   Author : Miguel Sanchis Sebastia; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Animal Bedding; Waste Textiles; Biomass; Biotechnology; Process Design;

   Abstract : The transition to a bioeconomy, in which resources from biowaste could be reclaimed for the production of chemicals, materials or fuels, could contribute to the establishment of a sustainable society by replacing fossil fuels as raw materials. The core of this bioeconomy would be biorefineries, which are similar to petroleum-based refineries, but are facilities where biowaste is processed and refined through different chemical and/or biochemical processes.

7. 5. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano

   Author : Rene Alvarez; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Altiplano; renewable energy; temperature fluctuation; low temperature; farm-scale digestion; manure; solid residues; Anaerobic Digestion; biogas;

   Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. READ MORE
