- More readily digestible product: The ALAP process produces amorphous cellulose, which is considered a more highly digestible form of cellulose than native cellulose I.
- Flexibility: Two streams are created by the process: one rich in cellulose and the other in hemicellulose-lignin. Each stream has the potential to be used to produce different products.
- Cellulosic biofuels: The invention would be beneficial to companies focusing on novel lignocellulosic biofuel production processes.
- Biomaterials: The resultant lignin fraction has potential to be used for the production of various biomaterials.
