Blusink

Blusink, an ocean-based carbon removal company, addresses climate change and ocean degradation by transforming seafloor spaces into carbon sinks. They use bioengineered ceramic pebbles, “Blusinkies,” made from industrial waste, which act as substrates for benthic organisms to enhance natural carbon sequestration. Blusinkies promote the formation of rhodoliths, storing carbon and boosting biodiversity. Their solution offers 5x faster carbon sequestration and 4x greater carbon uptake efficiency. With over 95% of materials from industrial waste, Blusinkies enable low-cost, long-term carbon storage and contribute to reversing ocean acidification. Their technology is built on a patented material.

Industry Problem

Blusink aims to address two major global issues: excessive atmospheric carbon emissions contributing to climate change and the degradation of ocean ecosystems.

R&D Focus

Blusink is conducting research and development in the niche area of ocean-based carbon removal and marine ecosystem restoration. Their focus lies in creating bioengineered pebbles called Blusinkies, which serve as substrates for benthic organisms, particularly coralline algae, to attach, grow, and capture carbon through natural calcification processes. By mimicking the structure and function of calcite seafloors and using over 95% waste-derived materials, Blusink enhances natural carbon sequestration while restoring biodiversity.

Innovative Solution

Blusink addresses the twin challenges of climate change and ocean degradation through its innovative solution—Blusinkies. These are apple-sized, bioengineered ceramic pebbles made from over 95% industrial waste materials, such as byproducts from brick and ceramic factories. Once deployed on the seafloor, Blusinkies act as a substrate for native benthic organisms, especially coralline algae, to colonize and grow. This process enhances natural carbon sequestration by promoting the formation of rhodoliths, which store carbon in the form of calcium carbonate for thousands of years. Over time, the Blusinkies evolve into self-sustaining marine ecosystems, boosting biodiversity, stabilizing pH levels, and supporting long-term ocean health, without introducing foreign species or synthetic chemicals into the environment.

Solution Effectiveness

Blusink’s solution is highly effective, offering 5x faster carbon sequestration than natural processes and 4x greater carbon uptake efficiency compared to land-based systems. With over 95% of its materials sourced from industrial waste, Blusinkies ensure low-cost, circular production while enabling long-term carbon storage lasting over 10,000 years. Early deployments show increased ocean pH and reduced dissolved inorganic carbon, highlighting their role in reversing ocean acidification and restoring marine ecosystems.

Product

Blusinkies are bioengineered ceramic pebbles designed to enhance marine carbon capture and restore ocean ecosystems. They serve as substrates for native marine organisms, particularly coralline algae, facilitating the formation of rhodoliths, natural carbon sinks that sequester carbon for thousands of years. By promoting the growth of these organisms, Blusinkies help increase ocean pH, counteracting acidification. – Customer Reviews- NA

Star Product

The star product is Blusinkies. It stands out because it uniquely combines bioengineered ceramic materials to accelerate natural ocean carbon sequestration, supporting marine biodiversity while providing a long-lasting, scalable, and cost-effective solution for carbon removal and ocean restoration. Its ability to foster self-sustaining ecosystems without introducing foreign species makes it an innovative and environmentally safe breakthrough in marine climate action.

Demo Product or Complete Product?

Blusink’s flagship product, Blusinkies, was first deployed in Madeira, Portugal, in an experimental site near the port of Canical. The initial deployment aimed to assess the settlement and growth of local coralline algae species on Blusinkies and evaluate their carbon sequestration potential.

Future Plan

Market Expansion

Blusink plans to conduct feasibility deployments in at least 20 countries within the next five years. This initiative is designed to demonstrate the scalability and viability of its business solution across various geographies.
