Paris (France): An accessible and sustainable concrete plant on the Seine River

Goal 4.5

Adopting a land management policy that strikes a balance between urban uses and the active port, especially on the waterfront.

Challenge(s)

How can transition zones in port areas promote integration with the city?

Best Practice

Implementing eco-friendly design principles and promoting public engagement are key strategies for transforming outdated industrial sites into assets for the environment and the community. Using green building standards and prioritising measures to minimise environmental impact, industrial facilities can enhance operational efficiency while mitigating potential negative effects on the surrounding ecosystem. Additionally, integrating public spaces and access points to the waterfronts improves the appeal of industrial areas and promotes a sense of community. In Paris, an old industrial port shows how design choices can enhance the integration of industrial infrastructure and urban context.

This good practice also includes objective 6.1 (Developing all types of promenades and other open spaces in Port City interface zones to promote a better understanding of port and logistic activities) of the AIVP’s 2030 Agenda.

Case Study

In 2010, as part of the redevelopment of Paris’ Tolbiac industrial port, the CEMEX group inaugurated a concrete plant dedicated to special types of concretes. The site, on the banks of the Seine River, had been occupied by CEMEX since 1979, but it became obsolete over time and in 2009, the old unit was dismantled to provide space for the new plant. This newly constructed plant has adhered to the “Haute Qualité Environnementale” (HQE, High Environmental Quality) standards, a French certification system for green buildings. Each silo in the plant has a dust filter and a supply security system to prevent any errors in the mixing of various types of cement. Moreover, the plant has reduced its footprint by two-thirds compared to the previous production unit. Given its site, the company and architects paid attention to the connection with the city. More than half of the area was left untouched in order to create two promenades, the first behind the quays and the other along the quays, to ensure continuity with the recreational amenities located in the port of the Gare. Additionally, both banks of the Seine will remain accessible to the public outside of the plant’s working hours, and tour groups can visit the factory during scheduled hours.
