1. 1. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Lakshay Vashist; [2023]
   Keywords : Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

   Abstract : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. READ MORE

3. 2. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

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

   Author : Danilo Esteban Ortiz Sarasty; [2023]
   Keywords : Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

   Abstract : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

4. 3. SUSTAINABILITY OF MULTI-STORY WOOD BUILDINGS : Can the Swedish forestry keep up with the demand?

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

   Author : Celine Kozak; [2023]
   Keywords : Sustainability; green washing; multi-storey wood buildings; clay; climate change; forest; sweden; case study; life cycle; architecture; Hållbarhet; Green washing; trähus; lera; klimat; skog; sverige; flervåningshus; fallstudie; livscykel; arkitektur;

   Abstract :   Wood has been traditionally used as a construction material in Nordic countries such as Sweden dating back to the 12th century. Using wood as a building material for the construction of buildings with more than two stories became the norm around the 1850s and has only increased with the pressing need for more sustainable and environmentally friendly alternatives to materials such as concrete.

5. 4. Tribology of Polymer Composite with Low Load Application for Automotive Industries

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Martin Asuquo; [2022]
   Keywords : ;

   Abstract : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.

6. 5. Biochar and hemp as peat substitutes in organic growing media : effects on nutrient availability and nutrient uptake

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Malin Nilsson; [2022]
   Keywords : Growing media; substrate; biochar; hemp; peat substitution; nutrient availability; nutrient use efficiency;

   Abstract : This study aimed at evaluating the suitability of biochar and hemp as partial or complete replacement of peat in horticultural growing media, with specific emphasis on the effects on nutrient availability and plant nutrient uptake. The study was motivated by the environmental concerns surrounding the use of peat, along with a desire to explore possible uses for biochar and a crop residue from hemp cultivation. READ MORE
