A group of researchers from universities in Thailand and Malaysia have collaborated to develop a unique film that is good for the environment and can decompose naturally. This film was created using leftover pineapple stems, which helps reduce the use of harmful plastic films. This new film has the potential to be used as packaging material, contributing to a more sustainable way of doing business and promoting a circular economy.
The researchers successfully developed a biodegradable starch film derived from pineapple stem waste, offering a sustainable alternative to non-biodegradable petroleum-based films commonly used for single-use applications that do not require high strength.
The key ingredient utilized in this film is high amylose starch extracted from pineapple stems, which serves as the matrix for the material. To enhance its ductility and flexibility, glycerol and citric acid were incorporated as additives.
