About Me

I’m an award‑winning packaging and sustainability specialist who brings clarity and confidence to complex challenges. After more than twenty years leading major programmes across retail, manufacturing and recycling, I know how to turn technical and regulatory complexity into solutions that actually work.

​

I’m trusted for my ability to cut through fast‑moving legislation, including pEPR, PPT, PPWR, and translate them into clear, commercially grounded action. My strength is my ability to simplify and refine packaging systems, strengthening supply chains and building circular solutions that are practical today and future‑ready for tomorrow.

​

As an independent consultant, organisations come to me when they need trusted and decisive expertise that removes ambiguity, reduces risk and accelerates progress. I deliver clarity that stands up to scrutiny and solutions that create real, lasting value.
