Industry : Green Packaging

Alternatives to plastic

University: São Paulo State University

Objective of study: Reducing the growing generation of solid waste in the form of dumped plastic food packaging

Process and applications:

  • Industrial waste is reused to produce alternatives to plastic
  • Reused bacterial cellulose scraps usually thrown away by manufacturers of wound dressings to make strong biodegradable film for food packaging
  • The film is made from hydroxypropyl methylcellulose (HPMC) and bacterial cellulose scraps left over from industrial processing
  • Both raw materials are sustainable. They are combined to produce a biodegradable film of bacterial cellulose nanocrystals and HPMC


  • Wanted to create greener protocols for the development of novel composites, from the material itself to its origin
  • It gives the material distinct properties such as high tensile strength
