1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : David Lundberg; [2024]
   Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

3. 2. Quantifying liquid food waste : levels of liquid coffee waste, its causes and barriers and drivers for quantification in the Swedish food service sector

   University essay from SLU/Department of Molecular Sciences

   Author : Rosa Hellman; [2024]
   Keywords : sewage food waste; beverage waste; direct measurement; hospitality; restaurant; serving waste; food waste cause;

   Abstract : Food waste is a waste of resources required throughout the entire supply chain, leading to environmental impacts that could have been avoided. Coffee has a relatively high environmental impact partially due to the high consumption. To identify levels and sources of food waste, and consequently prevent it, quantification is used. READ MORE

   Keywords : ;

   Abstract : Northvolt is committed to developing the world’s greenest battery. To achieve this,energy-efficient production processes are essential and dehumidification is a crucial, yet energy-intensive, process for battery production. READ MORE

5. 4. Microplastics in Scanian wetlands : Sege river & Kävlinge river

   University essay from Malmö universitet/Institutionen för Urbana Studier (US)

   Author : Ludvig Stoltz; Pernilla Leijon; [2023]
   Keywords : plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

   Abstract : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. READ MORE

6. 5. Waste Analysis on a Production Line - A Case Study

   University essay from Lunds universitet/Industriell Produktion

   Author : Sanna Treptow; Déspina Karida; [2023]
   Keywords : Sustainable manufacturing systems; Sustainable production; Lean production; Just in Time Production JiT ; Kanban; Waste; Environmental Value Stream Mapping EVSM ; Production Performance Matrix PPM ; Key Performance Index KPI ; Technology and Engineering;

   Abstract : This study aims to assist Swedish company Clemondo AB in reducing waste in production, where the goal is to determine where waste appears as well as make suggestions for potential improvements, which are presented as Key Performance Indices (KPIs) and minimized manufacturing costs. Citation chaining is used to retrieve extant literature, while other productions and process-related information are gathered through observations and discussions. READ MORE
