A senior executive at the world’s largest bunker trader and supplier, Bunker Holding, is switching to a role at the biofuels trading company that the parent group purchased last year.

Bunker Holding’s global head of commercial operations, Ask Michael Munck, is taking the reins as chief financial officer at sister company CM Biomass.

Danish bunker and tanker group United Shipping & Trading Company (USTC), which owns Bunker Holding, acquired a 60% stake in CM Biomass in March 2021.
