1. 1. Status Mapping of tank to grave management of Low-GWP refrigerants.

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Sandra Parra Gimeno; [2023]
   Keywords : Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

   Abstract : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. READ MORE

3. 2. Assessing the EnvironmentalPerformance of an In-Store VerticalFarming System : Identifying environmental hotspots for an in-store hydroponic vertical farmingsystem, using Life Cycle Assessment

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Axel Karlsson; [2023]
   Keywords : Vertical Farming”; “Life Cycle Assessment; Sweden; Environmental impacts; industrial symbiosis; Urban farming; Vertical Farming; Livscykelanalys; Sverige; Miljöpåverkan; Industriell symbios; Stadsodling;

   Abstract : The world is facing many challenges to be able to ensure food security, such as anincreased food demand coming from an expanding world population andurbanisation, worsened agricultural opportunities from increased land deteriorationand significant environmental impacts coming from the food sector. Thus, there is aneed for new agricultural solutions to meet our needs whilst decreasing impactssimultaneously. READ MORE

4. 3. Fouling modelling in a UHT unit based on plant data.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Thai Lam; [2023]
   Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE

5. 4. CCU in Scandinavia: an uncertainty analysis regarding the future state of captured carbon in the region.

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : William Melander; [2023]
   Keywords : CCU; E-kerosene; Precast concrete; CO2 utilization; Scandinavian region; Defossilization; Technology and Engineering;

   Abstract : The urgent need to mitigate climate change has prompted researchers to investigate novel strategies to reduce greenhouse gas emissions. One promising technology that might ease the way for sustainable and circular economies is carbon capture and utilization (CCU), which not only captures CO2 emissions but also uses them to produce valuable products.
