1. 1. Comparative Study of the Role of Digital Technologies in Implementing Circular Economy Practices in Product-Service Systems (PSS) : An Analysis Across Varying Organizational Scales

   University essay from KTH/Produktionsutveckling

   Author : Ajay Surya Gnaneswaran; [2024]
   Keywords : Product Service Systems; PSS; Circular Economy; CE; Digital Technology; DT; Industry 4.0; Circular Strategies; Barriers and Opportunities; Qualitative; Product-tjänste system; PSS; Digitala Teknologier; DT; Cirkulär Ekonomi; CE; Cirkulära Strategier; Industri 4.0; Utmaningar och Möjligheter; Kvalitativ.;

   Abstract : This thesis investigates the integration of digital technologies (DT) within Product-Service Systems (PSS) and their role in promoting Circular Economy (CE) practices. Despite increasing recognition of digitalization in industries with PSS offerings, research on DT as a catalyst for CE, especially across organizations of various sizes, remains limited. READ MORE

3. 2. Acoustic Characterization of Catalyst

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Surachit Dokson; [2023]
   Keywords : ;

   Abstract : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. READ MORE

4. 3. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mathias Schmekel; [2023]
   Keywords : Model predictive control; Selective catalytic reduction; Nitrogen oxides; Modell-prediktiv reglering; Selektiv katalytisk reduktion; Kväveoxider;

   Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

5. 4. Nanoscale characterisation of model Ni-Mo catalyst active phases

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Jonas Elmroth Nordlander; [2022]
   Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

   Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

6. 5. CCS via Electrochemical CO2 Reduction to Ethylene-based Polymeric Construction Materials

   University essay from KTH/Kemiteknik

   Author : Christian Taylor; [2021]
   Keywords : CCS; Electrochemical CO2 Reduction; CO2 to Ethylene; Power-to-X; Polymeric Construction Materials; Circular Carbon Economy; Electrolysis; CO2 electroreduction; CCS; Elektrokemisk CO2-reduktion; Koldioxid till Eten; Power-to-X; Polymera konstruktionsmaterial; Cirkulär kolekonomi; elektrolys; CO2-elektroreduktion;

   Abstract : IPCC SR15 rapporterade att alla framtida scenarier för att begränsa klimatförändringen till 1,5°C är starkt beroende av negativa utsläppstekniker, såsom geografisk CO2-lagring som används av Stockholm Exergi’s Värtaverket. Men kan man uppnå starkare klimatvinster genom en cirkulär koldioxidekonomi? Bildandet av en cirkulär koldioxidekonomi är absolut nödvändigt för att uppnå global koldioxidneutralitet, men hur kommer vi dit? Elektrolys av CO2 erbjuder en ekonomiskt och miljömässigt attraktiv väg för att uppgradera CO2-utsläpp till värdefulla bränslen och råvaror, vilket minskar användningen av fossila resurser och CO2-utsläpp till atmosfären.
