The chief executive of Realliance, a community interest company that supports third sector organisations working in recycling, will leave the organisation after six months in charge.
Tim Adkin, who was appointed in August, will this week leave the organisation at the conclusion of his six-month probationary period. He will be replaced by an interim director.
Ray Georgeson, chair of Realliance, said: "Tim leaves with our good wishes and thanks for the development work he completed but the board wishes to find someone else to take the organisation to its next stage of development."
Realliance, a joint venture by the four largest recycling and reuse networks in the UK, issued a statement saying the remaining management team would "work to a set of refocused goals to enable the sustainable resource sector to capitalise on its central role in the low carbon economy and green skills market".
Adkin declined to comment.
