Clean-up teams attended the site of the tyre fire at Gascoigne Wood at Sherburn-in-Elmet last weekend.
North Yorkshire Police said the blaze of 15,000 tonnes of tyres and waste material stored at the Newgen recycling plant would now be left to burn out.
Group Manager Dave Pitt from the Fire and Rescue Service explained: “We’ve been working with the recycling company to move some of the tyres when it’s safe to do so, so they can be extinguished.
“If we didn’t do this there is a danger that the fire could continue to smoulder for a very long time.
“This is part of our overall strategy to bring this to an end as quickly as possible; although we still expect the site to burn for another week or so.”
As a result of the work, it was advised that there may be additional smoke but the Environment Agency is working closely with the site owners and landlord to ensure a safe clean-up.
Local authorities warned people to remain inside and keep windows and doors closed is they smell smoke.
If anyone is concerned about the affects of the smoke on their health, they should seek medical advice by calling NHS 111.
