Plastic Pollution Clean Up Through Absorption

Plastic pollution clean up through absorption is now a possibility by using a combination of cotton and chittin to take microplastics out of the ocean...but can this work at scale?

In this episode of the "How to Protect the Ocean" podcast, host Andrew Lo discusses the pressing issue of microplastics in the ocean and introduces a promising new method for their absorption using a combination of cotton and chitin.

The mechanism involves creating a sponge-like substance called CT cell biomass, which combines cellulose from cotton and chitin from squid. This innovative material is designed to effectively capture microplastics from water. The process begins by breaking the original hydrogen bonds in cellulose and chitin, allowing them to bind together and form a stable framework with numerous activated hydrogen bonding sites. This structure enhances the material's ability to absorb microplastics through various interactions, including physical interception and electrostatic attraction.

Research indicates that this foam can remove 98 to 99.9% of microplastics from water samples, showcasing its potential as an eco-friendly solution for addressing microplastic pollution. The episode emphasizes the importance of developing sustainable strategies for microplastic remediation in aquatic environments, while also highlighting the need for broader efforts to reduce plastic usage at the source.
