It’s the start of a fresh new year and we are delighted to announce two new appointments to our technical team, 4R Environmental Consultants. Mark Stacey and Esther Koroma have recently joined us, each bringing a unique set of skills and experience which complement the technical services we offer.

Mark is a chartered environmental scientist who studied at the University of St Andrews. He has specialised in the project management of a wide range of environmental engineering and contaminated land remediation projects, providing technical expertise, regulatory liaison and carrying out environmental investigations. Mark will be reconnecting with his rural roots, and as well as being a member of the technical consultancy team,  he will also be focusing on technical innovation and business development for the group.


Esther is a professional chemist and graduate of the University of Aberdeen. Having worked for a range of UK leading environmental laboratories and most recently an agricultural chemical manufacturer, she brings a wealth of established expertise relating to environmental monitoring of organic pollutants and applied chemistry. Her skillset complements the strengths of the existing consultancy team and Esther will be focussing on environmental permitting and advancing our in-house technical services.


We are very pleased to welcome both Mark and Esther to the 4R family, and we are sure many of our clients and friends will meet them in due course.
