 The resulting protolignin contains high levels of beta-04 structures, which are important structural elements of lignin. Additionally, this process does not require any additional solvents or chemicals, making it more environmentally friendly than other methods. The team also scaled up their process to produce kilograms of protolignin, demonstrating its viability for industrial applications.
