Drivers and barriers for circular development in Swedish furniture industry
(2026) Lövhall, Johannes; Håkansson, Josefin
The Swedish furniture industry is facing increasing pressure to transition towards more circular practices. Low national levels of circularity indicate significant losses of value and resources, while European and national strategies are creating new expectations for industry actors. In this context, circular development is becoming increasingly relevant for furniture manufacturers and the wider network of actors surrounding them. This study investigates how actors in the furniture industry, comprised of mainly small and medium enterprises, currently experience circular economy, and how collaborations can play a part in supporting transition. The study is based on an interview study comprised of 21 interviews held with industry experts in qualitative research design. A key goal was investigating current experiences of circular economy transitions, and to explore how interorganizational collaborations can facilitate development of circular business models through directed and conventional content analysis. Interviews were conducted with actors within the value chain, ranging from suppliers to retailers. A snowball sampling technique was used to identify interviewee candidates. Empirical data was analyzed with 4R (reduce, reuse, repair, recycle) strategies, in a multilevel perspective supported by ARA network framework. The findings show several challenges connected to circular development, including inter- organizational coordination, product design, market demand, logistics, and data management. At the same time, the study identifies important drivers and opportunities. Product longevity, including both technical durability and timeless design, is a central foundation for circularity. Collaboration across the network can also support circular strategies by connecting complementary resources, activities, and roles between actors. The study concludes that circular development in the Swedish furniture industry cannot be understood only as a firm-level issue. Instead, circularity depends on how actors, resources, activities, and system conditions are connected across the wider furniture network. A key condition for circular development is therefore alignment between firm-level capabilities, coordination between actors, and broader system conditions such as regulations, procurement criteria, and market expectations.

Transforming Internal Transport Choices – From Functional Practice to Structured Decision
(2026) Edeslätt, Lucas; Edvardsson, Filip
This study develops a structured decision-support model for evaluating and comparing transport alternatives for replenishment orders in a global supply chain. A case study was conducted at Company X which evaluates their currently used practice in comparison to a set of transport alternatives. Through which a calculated and theoretical reasoning behind their currently used transport alternative Parcel is provided. A hybrid multi-criteria decision-making (MCDM) framework was constructed, using the Analytical Hierarchy Process (AHP) for creating weights for the criteria and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) II to compare the alternatives. The alternatives, criteria and weights were decided in conjunction with the stakeholders of Company X. Five transport alternatives were evaluated: Parcel, Pallet Express, Pallet Standard, Pallet Consolidated and Sea Freight. The alternatives were evaluated across four criteria: Freight Cost, Lead Time, Delivery Reliability and Environmental Impact. The weight of the criteria was gathered through queries and validated by both aggregated individual judgements (AIJ) and aggregated individual priorities (AIP), resulting in a consistency ratio of 0,04. Two datasets were used, dataset 1 and dataset 2, to evaluate the model and its results. The different datasets consist of products with different characteristics and costs. The results show that their currently used transport solution ranks first in the PROMETHEE II model with dataset 1 with a Net Flow of 0,3605 and achieves the lowest Total Cost of €60 664. Pallet Consolidated emerges as the preferred transport solution for dataset 2, which validates the supply chain strategy theory of there’s no unified optimal solution that can be applied to all products. Parcel performs the best in the two highest weighted criterion: Delivery Reliability and Lead Time, bringing attention to the subjectivity of MCDM models. The research validates Company X current transport solution for replenishment orders and provides a scalable, data-driven framework to evaluate future datasets.
Bit-Mouth Interaction in the Horse: A Multifactorial Analysis of Material, Geometry, Anatomy and Rider Influence
(2026) Rubin, Vendela
Understanding bit-mouth interaction in horses requires an integrated evaluation of material properties, bit geometry, equine oral anatomy and rider-related factors. This study employed a triangulated qualitative design combining a structured literature review, mechanical material analysis and expert interviews to investigate how these factors influence pressure distribution and the risk of bit-related injuries. Mechanical data demonstrated substantial differences between commonly used bit materials, where metals provided greater structural stability but increased the risk of tooth-related injuries, while softer materials such as TPU and leather reduced stress concentrations on the teeth yet were associated with a higher prevalence of lesions induced from friction. Bit geometry and fitting emerged as equally critical determinants, with thin, correctly sized mouthpieces offering superior stability and reduced tissue compression. Expert interviews highlighted underdocumented clinical findings, including low grade mobility and excessive wear of the P2 teeth, as well as the central role of rider balance, rein tension and technique in modulating mechanical load. Variation in equipment use was identified as an important, but under-recognized strategy for reducing cumulative stress on the tissue. Overall, the findings demonstrate that bit–mouth interaction is multifactorial and cannot be understood through material or design parameters alone. An integrated approach that considers mechanical behavior, anatomical prerequisites and rider influence is essential for improving bit selection, fitting practices and equine welfare.
Surface Functionalization of Screen-Printed Carbon Electrodes for Electrochemical Biosensing in Equine Saliva
(2026) Gustafsson, Agnes
Osteoarthritis (OA) is a progressive, long-term inflammatory condition that damages joint function and causes significant pain in both humans and animals. Many imaging techniques struggle to detect OA in its early stages, making early diagnosis challenging. A promising alternative is biomarker monitoring using electrochemical biosensors in saliva. The aim of this thesis is to investigate surface modification on screen-printed carbon electrodes as a model system for biosensor functionalization. The work focuses on establishing and evaluating a controlled surface chemistry using linker and passivation layers that mimic the immobilization strategy intended for future antibody-based sensing systems. Screen-printed carbon electrodes were functionalized using a PEG-based linker and click-chemistry-based surface modification. The surface immobilization was investigated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), field-effect transistor (FET), and chronoamperometry (CA) measurements. Surface modification could be observed using CV, while EIS showed weaker but supporting trends. Transistor measurements showed slight trends, but additional measurements are needed to determine whether the observed changes were caused by surface modification. CA measurements showed no clear evidence of binding. Overall, these findings demonstrate that the investigated surface chemistry can be immobilized on screen-printed carbon electrodes and detected using electrochemical methods, providing a foundation for future biosensor design, where the next step is to introduce Fab’ fragments for biomarker binding. However, further optimization of both the surface modification and measurement setup is required.
