Abstract:
Methods for converting waste streams from the wood pulping industry to high-value surfactants are described. For example, isolated lignin and lignosulfonate or waste streams containing lignin and lignosulfonate can be directly converted to surfactants, or they can be first converted to methylol derivatives and treated with further reagents to produce surfactants.
