Matt Bellamy - Cat Tech Europe Ltd, Regional Manager

Matthew’s passion for environmental studies formed the basis of his career.  After studying at Hull university his interest in the environment & waste management took him to the local council where an understanding of domestic and commercial waste management inspired him to look further into the private sector.

This has since developed into a career in providing industrial site services and hazardous waste management.   Thanks to Matthew’s ability to learn and adapt he has been able to quickly progress his career through from a local sales role to now a European Regional Manager at Cat Tech Europe Ltd.

Along the way he has honed his knowledge in all aspects of industrial cleaning such as tank cleaning, high pressure water jetting, automated heat exchanger extraction and cleaning and more lately into the unique world of catalyst handling services.  His career path has also included working for a catalyst handling competitor, but this knowledge has been rapidly expanded upon since his time at Cat Tech Europe Ltd whilst developing his skill set even further.

Matt was first attracted to the role at Cat Tech due to the opportunities for international travel and a unique market place which differentiates itself from the day-to-day industrial services sector due to the unique hazards involved, quality control requirements and professional planning and service delivery.  Since joining Cat Tech, Matt has helped to develop existing and new client relationships and now manages the European regional assets.  

Not only does he have a passion for providing a high level of customer service but he relishes building upon and creating new customer relationships.
