1. 1. Biogasproduktion vid samrötning av substrat tillgängliga vid lantbruk : Småskalig rötning vid Lillerudsgymnasiet

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Cecilia Svensson; [2023]
   Nyckelord :Biogas; agriculture;

   Sammanfattning : The world is currently heavily dependent on fossil sources and the use of fossil fuels leads to increased global warming. One of the solutions to this environmental problems is biogas. LÄS MER

3. 2. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

   Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

   Författare :Louise Westin; [2023]
   Nyckelord :Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

   Sammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER

4. 3. TECHNO-ECONOMIC ANALYSIS OFRENEWABLE GAS PRODUCTION AND ELECTRICITY GENERATION FROM ORGANIC WASTE : A Feasibility Study of a Conceptual Biogas Plant in the Santander Region, Colombia

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Nelly Sassersson Busadee; Laura Ahmed; [2023]
   Nyckelord :Organic waste; Biogas; Biomethane; Hydrogen; Waste valorisation; Anaerobic digestion; Combined heat and power; Water scrubbing; Biogas upgrading; Steam methane reforming; Techno-economic analysis; Sensitivity analysis; Colombia;

   Sammanfattning : Strategies to harness the energy from organic waste is gaining importance on a global scale, especially in countries with large quantities of it. In this paper, a techno-economic analysisand a field study were performed to investigate the feasibility of five scenarios for a conceptual biogas facility, based on a case study from Colombia.

5. 4. A process to assess fossil-free transport transition pathways and develop a sustainability roadmap for transport purchasers

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Lauren Brach; [2023]
   Nyckelord :Roadmap; corporate carbon strategy; decarbonisation; transportation; fossil-free; Earth and Environmental Sciences;

   Sammanfattning : Most (93%) of the greenhouse gas emissions in the transport sector come from road traffic in Sweden which includes passenger and freight transport activity (Trafikverket, 2022). The aim of this thesis was to understand pathways that transport purchasers can pursue to reach the fossil-free transportation goals from manufacturing plant to customer and to develop a process for assessing a market and developing a roadmap for achieving fossil-free transportation.
