Justin McKay is a Chartered Mechanical Engineer specialising in manufacturing efficiency, product development, and operational performance across complex value chains. He works with organisations to unlock measurable improvements in productivity, cost, and sustainability — translating technical depth into commercial results.

With a background spanning materials science, engineering, programme leadership, and cross-functional delivery, Justin has led the optimisation of manufacturing systems, reduced time-to-market, and implemented scalable, low-carbon solutions across global operations.

He has delivered large-scale facility developments, including hydrogen fuel cell and electrolyser plants, and led lean transformation programmes that have achieved significant efficiency gains, cost reduction, energy savings, and workforce optimisation. His approach combines strategic planning with hands-on delivery — from high-volume processing lines and product re-engineering to continuous improvement across end-to-end manufacturing systems.

As a Manufacturing & Sustainability Consultant at LDNY360, Justin supports organisations to:

  • unlock immediate operational efficiencies
  • embed sustainability into products and processes
  • re-engineer manufacturing systems to reduce embedded carbon
  • align lean methodologies with sustainability and compliance metrics

For some clients, this means targeted, rapid interventions — energy and resource audits, practical process upgrades, or capability-building through structured training. For others, it involves deeper transformation: redesigning products and manufacturing systems, integrating circular economy principles, and building long-term sustainability roadmaps that support scale and investment readiness.

Justin’s work consistently delivers commercial return alongside environmental value. His collaborative, systems-led approach enables LDNY360 clients — from advanced manufacturers to specialist contractors and professional service firms — to achieve quick wins, smarter processes, and sector-leading transformation, while building capability for long-term growth.
