Valorization of paper waste sludge to produce films for packaging

The global production of paper was more than 400 million tons in 2020, and about 40–50 kg of dry sludge/ton paper produced was generated. The management of this huge volume of solid waste material has become a serious problem for paper industry and an environmental challenge. Sustainable practices, alternative to disposal by landfilling, must be developed. The present work studied the potential of reusing sludge waste from paper manufacturer with the purpose to produce cellulose acetate films.
