Master of Engineering Leadership in Sustainable Process Engineering (MEL) postgraduate personal statement example

Personal statement example

The final rinse on our clean-in-place cycle for Line 2 ran for eight minutes, and nobody on my shift could tell me why it was eight rather than six. I work as a process technician at a soft-drinks bottling plant, and over a few weeks last spring I started noting the conductivity readings at the rinse outlet. On most runs they settled back to the incoming water value well before the timer finished. I raised this with my shift manager, who passed it to the quality team, and after a validation trial with swab tests the rinse was shortened on that line. It was a small change. What stayed with me was that it took a technician with a notebook to question a number that had simply been inherited, and that the change needed people in quality, production and hygiene to agree before it could happen. That is the combination of technical judgement and working across a site that I want to develop through postgraduate study in sustainable process engineering.

My undergraduate degree in chemical engineering gave me the fundamentals: mass and energy balances, separation processes, reaction engineering and process control. The work I found most absorbing was my final-year design project, in which a group of four of us developed a solvent recovery unit for a fictional pharmaceutical intermediates plant. I was responsible for heat integration. Using pinch analysis, I built composite curves for the hot and cold streams and proposed a heat exchanger network that reduced the modelled hot utility demand compared with our first design. The harder part was explaining to my teammates why some exchanger matches that looked attractive would break the pinch rule and increase utility use elsewhere. I learned to present the trade-off with a simple grid diagram rather than defending my spreadsheet, and the group's final design adopted a version of my network with one match removed for practicality.

That project, and my job since graduating, have made me aware of how much of sustainability in industry is unglamorous: water use per litre of product, steam traps, compressed air leaks, changeover waste. At the plant I help log line efficiency and assist with changeovers, and I have seen how decisions about scheduling affect cleaning frequency, which in turn affects water and chemical consumption. I do not have authority to change schedules, but I have learned to ask useful questions of the people who do and to bring data with me when I ask.

Outside work, I volunteer on Saturday mornings at a community bike repair workshop. Most of the job is teaching people to fix their own punctures and adjust brakes, and the rest is sorting donated parts so that usable components are not thrown away. It is not engineering in any formal sense, but it has made me patient at explaining practical things to people with very different levels of confidence, and it has given me a habit of asking whether something really needs replacing.

I have been reading to widen my perspective beyond the plant floor. David MacKay's Sustainable Energy – Without the Hot Air was useful for its insistence on putting energy claims into consistent units before arguing about them, which is a discipline I try to apply at work. I have also been reading introductory material on life cycle assessment, because I want to understand how process-level choices compare once upstream and downstream effects are included.

I am applying for a programme that combines advanced process engineering with leadership because I can see both halves of the problem from where I stand: identifying where a process wastes resources, and persuading a team that changing it is worth the effort. I want to return to industry able to lead improvement projects with sound technical analysis behind them, and I believe I bring the grounding, the curiosity and the working habits to make good use of the opportunity.
