AI Technical Summary

Technical Problem

The deficit in biogenic carbonate sedimentation and oceanic CO2 capture has increased due to ocean acidification, threatening marine ecosystems, and existing methods do not effectively compensate for this deficit through the biomineralization of calcareous organisms in mariculture.

Method used

Cultivating calcareous mollusks in Mexico to capture inorganic CO2 via biomineralization, developing methods to measure and quantify CO2 capture, handling and disposing of their shells, and using these shells to create modular artificial reefs that enhance marine electrolysis and carbon sequestration.

Benefits of technology

The process effectively mitigates oceanic CO2 deficit by increasing alkalinity, reducing acidification, and providing sustainable aquaculture benefits, while creating fishing shelters and promoting biodiversity, with integrated monitoring systems ensuring long-term CO2 capture and reef restoration.

Abstract

The present invention falls within the technical field that provides innovative solutions that help protect and restore reefs, inter alia, offsetting ocean CO2 capture deficit by sequestering (inorganic) CO2 through the biomineralization of calcareous organisms from mariculture, and depositing the shells from same in modular artificial reef structures, using a novel method completely different from those already known.
