France: Concrete block producer Bloc Béton 17 has produced 90% recycled stackable modular elements featuring dredged aggregates from the Port of La Rochelle. CRH subsidiary Eqiom supplied slag cement and Herige subsidiary Edycem supplied ready-mix concrete for the project. Environmental services company Solvavor Aquitaine dredged the aggregates. The pilot produced 310 stackable blocks for use in the construction of storage space, along with 10 planters and benches. It cost €120,000 and was 50% financed by the Nouvelle-Aquitaine regional government.
