Sustainable upcycling topological artificial reef restoration method

Abstract

comprises the following steps: S1. Pretreatment of seashells: Collect, sterilize and crush seashells to reach 2,500 meshes. S2. Preparation of 3D printing materials: Mix polyhydroxyalkanoate and additives with the calcium carbonate powder obtained in S1, and prepare 3D printing wires using an extruding machine. S3. Preparation of 3D printed artificial reef: Use the 3D printing wires to print artificial reef modules with a topological shape. S4. Installation of artificial reefs: Fix and connect the printed artificial reef modules to each other, and fix them according to different occasions, for example, fix in form of floating reefs or on benthal terrain. The invention enables efficient, environmentally friendly and customizable restoration of marine habitats. The method offers advantages such as material sustainability, topologically optimized structures that enhance water flow through artificial reefs, flexible installation, substantial ecological benefits, and lightweight artificial reefs that facilitate transportation.
