Andy Tittensor

I Started work on the plant as a construction worker for the original owners when it was a grass field. After getting involved with the commissioning of the plant we came online in September 2007. We had only been running for about a week when the original plant manager handed in his notice. As the only person left who new how to run the plant, I was thrown in the deep end with a steep learning curve and 2 more plant managers in twelve months I was made the plant manager late in 2008. I have had responsibility for running the site for 17 years and the new briquetting plant for the last 2 years.
