International research travel has an environmental cost, and I think it is worth being direct about that rather than overstating the green credentials of what is, at its core, a flight to Spain. What I can honestly say is that I have thought carefully about the purpose of this placement and how the research itself connects to broader sustainability goals.
The group I am joining at the Instituto de Tecnología Química (ITQ-CSIC) in Valencia works on catalysis for sustainable organic reactions. Two of their recent projects are directly relevant here. The first involves replacing the Lindlar catalyst – an industrial standard containing lead, a toxic heavy metal – with ultrasmall palladium species active at parts-per-million concentrations, which are recyclable and avoid hazardous byproducts. The second replaces soluble, unrecoverable rhodium catalysts with solid zeolite-supported systems that can be filtered and reused without significant loss of activity. Both projects connect to SDG 12 (responsible consumption and production) and SDG 3 (good health) in a concrete rather than aspirational sense.
Contributing to this research as an undergraduate means the placement has value beyond my own training. The methods being developed in this group have genuine potential to reduce the environmental footprint of industrial chemical processes, and being part of that work – even at an early stage – feels like a reasonable justification for the travel involved.
In the laboratory I will work within standard green chemistry principles: minimising solvent volumes where possible, following waste disposal protocols carefully, and reusing catalyst materials in line with the group’s existing procedures. These are not exceptional measures but they reflect how the lab already operates, given that recyclability is central to the group’s research agenda.
The international dimension of the placement also has longer-term value. Building research connections between UK and Spanish institutions, and returning with practical knowledge of heterogeneous catalysis that feeds into my final year at Liverpool, supports SDG 4 (quality education) and SDG 9 (innovation) in ways that justify the investment of making the journey.
I am aware that framing a research trip as sustainable because of what happens in the lab is not without its limitations. The flight still happened. But I think the most useful contribution I can make to this question is an honest account of why the placement is worth its environmental cost, rather than a list of measures that would overstate the case.
