  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

    University essay from SLU/Dept. of Energy and Technology

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

    Abstract : 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.

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  6. 5. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Christian Rotter; Erik Fagerberg; [2023]
    Keywords : additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

    Abstract : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. READ MORE
