The effects of EDTA on the isolation of cellulose from banana stem using atmospheric soda pulping / Nurul Amal Nadhirah Mohamad

The pulp and paper industry, which produces various types of papers, packaging materials, and household products, uses over 40% industrial wood traded globally. Non-wood cellulose isolated from agricultural residues, such as banana stems, offers an alternative to the limited supply of wood and envir...
