ABOUT LIGWOOD, LLC

Ligwood LLC is working closely with the USDA Forest Products Laboratory for thermally upgrading kraft lignin to various forms of proprietary, high value carbonaceous materials such as graphene and carbon foams.  

Lignin is a biowaste from pulping processes, more than 70 million tons of lignin are produced yearly worldwide. Ligwood LLC has established an ongoing collaborative R&D program with the US Forest Products Laboratory for production of carbon foams, a high value carbon material, by recycling lignin into Biochar to create carbon foams.

The goals of this collaboration are: 

• To develop a commercial manufacturing mode and demonstrate the existing carbon foam production process is scalable for high-volume production of valuable carbonaceous materials from lignin.
• ·To identify potential large volume applications of lignin-derived carbon foams.

The specific objectives for this research include:

•  Develop a commercial manufacturing mode for production of carbon foam materials from lignin.
• Demonstrate that the developed the manufacturing process is scalable.
• Optimize the scale-up manufacturing processes.
• Analysis and characterization of both lignin resources and final carbonaceous materials.
• Test physical and chemical properties of the carbon foam products.
• Investigate the potential large volume applications of lignin-based carbon foams.
