Reusable Lignin Material for CO2 Capture

Date:27 Aug 2024

Country: United States

Application

• Carbon Emission Mitigation: Efficient CO2 capture and release for reducing atmospheric carbon levels.
• Industrial & Agricultural Use: Recycled CO2 can be utilized in various chemical processes and applications.

Description

Researchers at Florida State University developed a novel lignin-based material that efficiently absorbs and releases carbon dioxide (CO2). This material can capture CO2 from both concentrated sources and ambient air, without needing high temperatures or pressure. It can be reused multiple times, making it a sustainable solution for reducing carbon emissions. The process is highly efficient, with CO2 release controlled by adjusting temperature.

Pathway Description:

Lignin is chemically modified to create a polymer that can capture CO2 from the air or concentrated sources. The polymer absorbs CO2 and forms a stable structure. When heat is applied, typically at 60°C under atmospheric pressure, the CO2 is released, and the polymer can be reused. The CO2 release can be controlled by adjusting the temperature, allowing the material to be efficiently recycled for repeated use in carbon capture.
