Researchers at Mizzou, led by mechanical engineering professor Yingchao Yang, are developing a biochar-based foam aimed at reducing the use of harmful chemicals in fire prevention and construction. BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, produced by burning organic material in an oxygen-deprived environment, is already known for its environmental benefits, such as improving soil health and acting as a carbon sink. Now, Yang is exploring its potential to control fires and enhance building safety, particularly in areas vulnerable to wildfires.

Supported by the USDA Forest Products Laboratory, Yang’s team is focused on creating a biochar foam that can be used as a core material for structural insulated panels (SIPs). These panels are commonly used in construction due to their strength and energy efficiency. However, traditional SIPs often contain harmful chemicals that pose environmental risks during disasters. The biochar alternative offers an eco-friendly, fire-resistant option that addresses this problem.

The research also extends beyond fireproofing, as Yang’s team plans to evaluate the foam’s mechanical properties, acoustic absorption, and durability under extreme conditions. With this project, Yang aims to advance sustainable forest management, improve fire-resistant housing, and contribute to environmental conservation efforts. Through innovative use of biochar, this work promises to make significant impacts on both safety and sustainability in construction.
