Open day

The annual Open day event at Langøya has a long history. The event takes places in August, usually on the first Saturday after the end of the school holidays.


Visitor numbers vary between 600 and over 900. The intention is to give visitors a good, factual insight into NOAH’s treatment processes for hazardous waste and contaminated earth, and also to show how NOAH works towards rebuilding Langøya after over 100 years of limestone extraction.
