1. 1. Life Cycle Assessment : a comparison of fossil energy use and climate impact on small scale manufacturing and large scale conventional manufacturing of textile toys

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

   Författare :Malin Henriksen; [2024]
   Nyckelord :textile toy; LCA; energy use; sustainable production; China; Sri Lanka; cotton production; fossil fuel use; GWP100;

   Sammanfattning : This study conducts a Life Cycle Assessment to compare the environmental impacts, specifically climate impact and fossil fuel use, of textile toys produced in China and Sri Lanka. Through evaluating large-scale industrial production in China against small-scale, handcrafted production in Sri Lanka, it identifies the considerable environmental footprint of cotton production in both scenarios.
