American Science and Technology Awarded Second New Patent
Summary
The patented process delignifies the lignocellulosic biomass by dissolving lignin in organic solvent and converts most of the hemicellulose to biochemicals (such as furfural, butyl acetate, etc.).“The new processes developed and tested by AST, produce pulp, bio renewable chemicals, and pure lignin.Wausau, WI, September 29, 2016 --( PR.com )-- American Science and Technology (AST), a sustainable technology company focused on providing R&D services to develop innovative processes that can produce cost-competitive renewable chemicals and materials from non-food biomass, has won a second patent (US 9,382,283 B2) in as many months, related to its Organosolv pulping process.The patented process delignifies the lignocellulosic biomass by dissolving lignin in organic solvent and converts most of the hemicellulose to biochemicals (such as furfural, butyl acetate, etc.).AST’s lignin, with high purity, has been used for various applications such as bio-renewable polymers, bio-renewable colorants for polymers, and as a base for composite materials.“Traditionally, the pulping industry has considered pulp as the end product of their processes and the only value to the remaining lignin was for burning as a low energy density fuel,” said AST President and CEO, Dr. Ali Manesh.
