Lignin to plastic opportunities

cup-973101 copy

Under the conditions evaluated by NARA to convert post-harvest forest residuals into biojet fuel, approximately two-thirds of the woody material is left over as a byproduct. This left over material is rich in lignin, a complex polymer molecule found in plant cell walls.

The USDA-NIFA, through the NARA grant, funds research to develop high-value chemicals and materials that can be made from the lignin-rich material left after the various …more

Slash removal and microbial communities

Monitoring equipment at the NARA long-term soil productivity site.

A key issue attached to the use of post-harvest forest residuals (slash) to make biojet fuel and other chemical products is how slash removal impacts the productivity and ecology of a working forest. The USDA-NIFA, through the NARA project, funds research to evaluate the impacts of slash …more

Extractives found in post-harvest forest residuals

sap-112363_1920

When it comes to evaluating an industry that uses post-harvest forest residuals (slash) to make bio-jet fuel and co-products, the primary components in softwoods, like Douglas-fir, receiving the most industrial interest are cellulose, hemicellulose and lignin. The cellulose and hemicellulose contain the simple sugars used to biofuel and other chemical products. The lignin is a byproduct of the fuel conversion process and can be used to make additional products like …more
