「HOTATETRAPOD」: Blue Carbon Wave Dissipating Blocks Utilizing Scallop Waste Shells
SHIMIZU CORPORATION
Technology / Service Summary
“HOTATETRAPOD” is a type of wave-dissipating block. It reduces sand consumption. 50% of the sand used in production can be replaced with crushed discarded scallop shells.
In addition, the surface has a ribbed pattern that resembles a scallop. This makes it easier for algae to attach. This contributes to the expansion of blue carbon.
Purpose
There is a lot of surplus shells from scallop processing plants in the production area. We will make effective use of these shells and upcycle them into eco-materials. This will reduce the consumption of sand resources. In addition, we can expect the adhesion of algae to improve the underwater environment and increase blue carbon.
Feature
Effect
By adopting HOTATETRAPOD, the amount of sand used as fine aggregate in concrete can be reduced by 50%.
