1. 1. Relationship between waste management in student accommodation and students' knowledge of waste management in relation to energy transition

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yong Lin; [2023]
   Keywords : Sustainable Development; Energy Transition; Waste Management; Waste Sorting; Pearson’s correlation coefficient; Student Accommodation;

   Abstract : In the context of the current energy transition and sustainable development, the promotion of waste separation and waste management is a good means of promoting the energy transition. Waste, when recycled, can contribute to the energy transition in many ways, for example by generating electricity, heating, recycling into raw materials for reuse and producing biofuels. READ MORE

3. 2. Development and Optimization of Near-infrared spectroscopy

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

   Author : Amanda Hahlin; [2023]
   Keywords : Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

   Abstract : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. READ MORE

4. 3. Quantitative and qualitative analysis of dyes in pulp from recycled textiles

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Karlsson; [2023]
   Keywords : Food packaging; coffee; permeability; recyclability; shelf life.; Technology and Engineering;

   Abstract : An important factor in preventing food waste is the ability to provide a product with a package according to its needs. The packaging material, in turn, needs to be recyclable in order to contribute to a circular use of materials rather than becoming waste. READ MORE

6. 5. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

   University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Author : Heba Alwan; [2023]
   Keywords : Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

   Abstract : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. READ MORE
