Port-city interfaces have grown apart over the last few decades, resulting in a disbalance between ports and cities. This thesis focuses on finding an approach to reuse and remediate unused industrial sites in sensitive port locations while making them ready for a post-carbon era. The project uses phytotechnologies for remediation of polluted soil on an old refinery site and the construction of a series of laboratories that are made from reused materials and productive phytoremediation landscape around the old refinery installations and are hosted by the old refinery installations,.
