1. 21. The grass is always tastier on the fruitful side : exploring the potentials, opportunities and challenges of urban food production: a case study of Uppsala

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Sanaz Kalantari; Rana Toprak; [2023]
   Keywords : Urbanization; grass lawns; urban agriculture; food production; Uppsala; Ultuna Permakultur; municipal sector; planning; establishing; management; ecosystems; human-nature connectedness; extinction of experience; top-down; bottom-up; landscape architecture;

   Abstract : Urbanization has globally led to economic and infrastructural growth but has also resulted in environmental degradation, decreased access to fertile agricultural land, increased food demand, and fragmentation of essential ecosystems. These challenges are prevalent in Swedish cities, including Uppsala, where green spaces are predominantly covered by lawns. READ MORE

3. 22. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Elise Meurs; [2023]
   Keywords : Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

   Abstract : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

4. 23. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

   University essay from KTH/Kemiteknik

   Author : Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
   Keywords : Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

   Abstract : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. READ MORE

5. 24. Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Xiaoming Wang; [2023]
   Keywords : boreal forest; conservation; restoration; connectivity; green infrastructure; GIS; Sweden; Earth and Environmental Sciences;

   Abstract : Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. READ MORE

6. 25. Coral Reef Restoration Enterprises

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Ileana Graf; [2023]
   Keywords : Coral reef restoration enterprise CRRE ; Nature-based enterprise NBE ; Coral business; Profitable coral reef restoration; Sustainable business model; Business and Economics;

   Abstract : Coral reefs are essential for providing ecosystem services to humans, including coastal protection, nutrition, and income opportunities for coastal communities. However, coral reefs worldwide have suffered severe damage due to anthropogenic factors, leading to their rapid degradation. READ MORE
