The fire burning at the Vale Business Park in Llandow is now out.
It began on November 26. A spokesperson for South Wales Fire & Rescue Service says efforts to tackle the blaze were hampered by the construction of the building - a former aircraft hangar built to withstand bombardment.
Firefighters are continuing to tackle a 'challenging and complex' blaze, which broke out at the Vale Business Park in Llandow on November 26th.
South Wales Fire & Rescue Service say the operation has been prolonged by the nature and volume of the burning material within the building, the strength of the building structure, challenging site conditions and the need to protect the environment.
Steady progress is being made and South Wales Fire and Rescue Service, Natural Resources Wales and the recycling company which owns the site, Site Serv, are working closely together to ensure that the fire is extinguished as rapidly as the constraints allow.
The organisations involved have expressed their thanks to the local community and businesses for their continuing patience and support.
Health authorities say the risk to public health associated with the fire is low.

People living nearby are advised to minimise their exposure to smoke arising from the fire - particularly those with pre-existing respiratory conditions.
Advice includes staying indoors where possible and keeping doors and windows closed.
Around 30 firefighters are still tackling yesterday's blaze at an industrial estate in the Vale of Glamorgan. The location of the fire at Llandow is different from the blaze at a Recycling Centre earlier this month. It could last for days.
