A User-Experience Based Design Support Framework to Develop Smart Sustainable Packaging
by Tamasine Camilleri
Due to the limited information available to designers in early design stages, this poses challenges for designers to make sustainably-conscious decisions. Smart take-away food packaging is adopted as a case study, since packaging loses its value once it is discarded after use, and with the short use-phase of take-away packaging, the resources required to develop the packaging are significantly larger than its use value. Furthermore, smart capabilities require a higher initial investment, in cost, material, and end-of-life processing. For these reasons, a design support framework will be developed to guide designers to strike a balance between various design aspects (such as sustainability) in early design stages.

Gender perspectives on resilient social capital: A comparison of Maltese and Syrian low-income households in Malta
by Nathalie Grima
"The Rio +20 United Nations conference on sustainable development in 2012, acknowledged that resilience was a prominent issue in “a new wave of thinking around sustainability in an age of economic and political instability" (Brown, 2014, p. 107). Since then, research in the field of social resilience has contributed to shifting the objective from transforming ‘vulnerable’ people to understanding their own coping capacities and identifying their own needs for transformation.
Using the two theoretical frameworks consisting of the subjective social resilience paradigm and the theory of social capital, this thesis is a comparative case study that explores the social relations within two social groups - a sample of people who identify themselves as Sengleani and another who identify as Syrians. The qualitative and feminist critical methodological approach gives priority to the research participants’ own perception of risk, sense of positionality, and gendered power dynamics in a society where class, gender and ethnicity intersect where relative poverty is concerned.

Regulating marine plastic pollution from land-based sources: Legal and policy solutions
by Jyothi Thomas
This research analyses the potential of International, European Union, and national legal frameworks in regulating marine plastic pollution from land-based single-use plastics and microplastics, identifies regulatory gaps, and recommends legal and policy measures to fill any shortcomings. While these laws and policies are often built on circularity principles, my work scrutinises the inherent tension between plastic’s chemical nature and the 'circular' aspiration of the law. By identifying regulatory gaps, the research highlights how current 'circular' strategies may inadvertently perpetuate downcycling rather than true sustainability. Ultimately, this study advocates for policy shifts that utilise environmental law principles such as the precautionary approach and preventive measures, to move beyond the limitations of recycling and also meet the fundamental waste reduction targets of SDG 12.4 and 12.5, alongside the marine pollution prevention targets of SDG 14.1.

Daring to take off the Hat. Reinventing Higher Education Pedagogies for the Teaching of Spanish Literature
by Alessia Cilia Portelli
Drawing on feminist new materialism, this thesis conceptualises canon formation as a dynamic institutional process informed by pedagogical practices, interpretative norms and material conditions of knowledge production. It examines the exclusion of women writers from the Spanish literary canon and analyses how higher education curricula reproduce gendered forms of epistemic authority through what is selected, taught and assessed. In doing so, it engages directly with SDG 4 (Quality Education) and SDG 5 (Gender Equality) by advancing critically reflexive pedagogical engagements attentive to the material and institutional conditions of knowledge production, thereby challenging structural inequalities in the production, validation and circulation of aesthetic and cultural values.

Post-Silicon System Level Optimisation of High-Speed Chip-to-Chip Interconnects
by Andre' Micallef
This work proposes a hardware-in-the-loop optimisation framework for high-speed communication links that improves signal integrity across dense multi-lane systems while reducing the energy required to maintain reliable data transfer. By targeting the Pareto-optimal balance between operating margin and power consumption, it supports more sustainable digital infrastructure through lower energy-per-bit and reduced power waste in data centres, AI systems, and edge devices. Its adaptive, post-deployment tuning approach also improves sustainability by extending system usefulness over time, compensating for drift, aging, and environmental variation without repeated retraining or disruptive failures. Overall, the research promotes a more resource-efficient and scalable electronics ecosystem by cutting operational energy demand, reducing unnecessary overdesign, and improving the long-term resilience of high-performance interconnects.
