Exploring Kelp's Potential in Sustainable Construction

KELECHI IHEANACHO, COLUMBIA GSAPP

This past summer, the GSAPP Natural Materials Lab at Columbia University embarked on groundbreaking research, exploring Long Island-harvested kelp's potential in sustainable construction. Graduate student Kelechi Iheanacho spearheaded preliminary experiments, focusing on kelp's reaction to water and heat, and its potential as a binding agent in earth mixes.

Key Findings and Future Directions:

Heat and Water Interactions

Experiments explored how heat, specifically at 140°F, impacts kelp's structure and properties

Kelp-Soil Composites

The lab examined various kelp-to-clay soil ratios, assessing kelp's ability to enhance earth mix strength and workability

Material Refinement

Research involved processing kelp into fine particles, including shredding and sifting down to 850μm

Kelechi's research exemplifies the innovative spirit driving sustainable construction. By exploring low-manipulation applications of kelp, the lab aims to unlock its potential in creating eco-friendly building solutions. This research will continue with the help of collaborators.

Beyond the Shore: Seaweed Research in the Lab

Volunteering with seaweed extends beyond traditional fieldwork. Kelechi Iheanacho's work demonstrates the crucial role of researchers who push boundaries and explore unconventional applications. Her dedication to understanding kelp's properties contributes significantly to advancing the sustainable materials industry.
