Colin Drummond has announced his retirement as chief executive of Viridor after 20 years in the job.
The waste firm said Drummond would take up the position of non-executive chairman once a successor is appointed, expected to be by the end of September 2013.
Ken Harvey, chairman of Viridor’s parent firm Pennon Group, said: “Colin has made a tremendous contribution to the success of Viridor and Pennon over many years. His leadership of Viridor and the development of its strategy have resulted in the company becoming one of the largest and best respected recycling, renewable energy and waste management businesses in the UK.
“He has put in place the next stage of the company’s strategy, securing a pipeline of energy from waste plants backed by public/private partnership contracts and associated planning permissions. Colin’s decision to retire is therefore a timely one so that his successor can lead the delivery of this major and exciting programme over the next five years.”
