Crews have been tackling the smouldering fires involving 3,000 tonnes of woodchip at South Wales Wood Recycling in Coity since last Monday.
Public health officials had advised nearby residents to keep doors and windows closed while the fire was burning.
The fire service said it was continuing to liaise with on-site management.
South Wales Fire and Rescue Service said Natural Resources Wales officials were also monitoring the situation.
A blaze at a wood recycling centre in Bridgend has finally been extinguished after burning for nearly a week.
