In 2016, the port of Tallinn installed a network of 20 sensors known as “eNoses” in the Port of Muuga and the Maardu sector. The sensors continuously analyse the chemical make-up of the ambient air in various parts of the port terminals and industrial or residential areas.
The data are available on a dedicated web app via a graphic interface, that shows the composition of the gas detected by each eNose sensor with a colour code.

E-Noses provides the port authorities and industrial operators concerned with a clearer picture of odours in and around the port zone, and acts as an early warning system so that measures can be taken when olfactive anomalies are detected. These anomalies can be caused by the chemicals stored or handled at the Port of Muuga.

The eNose project is inspired by a similar initiative at the Port of Rotterdam. It was made possible by cooperation between Estonia’s Centre for Environmental Research, Environment Agency, Ministry of the Environment, Environmental Inspectorate, the Port of Tallinn, and the operators present at the port of Muuga: Vopak E.O.S., Vesta Terminal Tallinn OU and Oiltanking Tallinn AS.
The Port of Tallinn and the operators provided 50% of the 120,000 euros in funding needed, with the remainder coming from the Environmental Investment Centre of Estonia.
