Abstract: A composition and method are disclosed for forming lignin-containing floccules from dissolved lignin, lignin nanoparticles, lignin colloids, or lignin-containing cellulose nanofibers. The floccules may be used to clean oil-contaminated materials such as oil-contaminated plastics or oil-contaminated water. The polymers and oil may then be recovered for further use, without requiring organic solvents.
