A team of scientists from the University of Sharjah in the United Arab Emirates has discovered a way to use shrimp waste, turning it into a material with extractive capabilities to slow climate change.
Conversion of shrimp waste
The research, led by Dr. Haif Al-Jomard and Professor Chaouki Ghenai, has found a way to convert shrimp waste into a type of activated carbon with a remarkable ability to adsorb carbon dioxide.

They also subject the material to a series of chemical and mechanical treatments to maximize its adsorptive properties.
This material resulting from this process, a porous biochar, has shown high carbon capture capacity and long-lasting stability. The research was published in the journal Nanoscale, highlighting that this CO₂ adsorbent could be used by industries with high emissions, such as power generation, cement and steel.
Professor Ghenai mentions that this waste-to-carbon technology is cost-effective and environmentally responsible, converting a problematic waste stream into a high-performance product.
The study demonstrates a clear alignment with the principles of the circular economy. The approach proposes waste valorization that converts by-products into valuable and efficient resources. Beyond carbon capture, activated carbon derived from shrimp waste has multiple potential uses, including water and air purification, solvent recovery and precious metal extraction.
