Can structural timber be recycled into new construction?

Yes, but with limitations. Reclaimed structural timber can be re-graded to current EN 14081 standards using visual or machine methods and reused structurally if it meets the required strength class.

Yes, but with limitations. Reclaimed structural timber can be re-graded to current EN 14081 standards using visual or machine methods and reused structurally if it meets the required strength class. However, timber that has been treated with preservatives (CCA, creosote) cannot be reused in interior applications and has restricted recycling routes. Untreated solid timber in good condition can be directly reused, re-sawn to new dimensions, or processed into engineered products like CLT or glulam if it meets lamination grade requirements.
