Industrial ecology is based on two principles:


  • The circular economy, which implies that the waste and co-products of some become resources for others.
  • Cooperation, which takes advantage of the pooling of services between companies or collaboration between local stakeholders on projects that promote progress and innovation.

The Port of Rouen has been involved in industrial ecology initiatives for several years within its territory, in the Port Jérôme industrial zone from 2010 to 2013 in collaboration with the Association Ecologie Industrielle Estuaire (AEIE - Estuary Industrial Ecology Association), and since 2013, in the Rouen port zone in partnership with the Rouen Normandy Metropolitan Area, the CCI and the Economic Development Agency.

More concretely, the Port of Rouen is involved in innovative projects, and in particular in developing a heating network in the commune of Grand-Couronne and the recovery of dredging sediments, a major subject for the Port.

The recovery of dredging sediments

The Port of Rouen has been developing partnerships for many years with quarries and construction companies with which it develops innovative projects such as the backfilling of gravel pits with dredging sediments and the recycling of sediments in the construction sector to replace alluvial aggregates.

The Slop Express barge collects waste from the port

The promotion of industrial ecology has made it possible to set up a waste collection service by barge in partnership with Ernett Propreté.

Recovering heat from the VESTA incinerator

The incineration of waste by the VESTA plant produces electricity and heat. An ecological heat recovery network is used to heat 10,000 individual homes.
