Bioplastic Production from Corn and Potato Starch and Its Industrial Applications
AI summary Read the abstract
This study describes how bioplastics can be made from corn and potato starch as a biodegradable alternative to conventional petroleum-based plastics, which currently see only 9% of global production recycled. The resulting starch-based bioplastic showed improved flexibility compared to earlier versions, suggesting it could substitute for conventional plastics in some applications and help reduce long-term plastic pollution.
Abstract Plastic has become an inevitable part of our daily life. According to OECD (Organization for Economic Cooperation and Development), around 460 million tonnes of plastic is produced worldwide, of which merely 9% plastic waste gets recycled while 22% is mismanaged. This causes severe hazards to the environment and lifeforms. In order to overcome this problem, bio-plastics are introduced. They are considered green materials substitutes for plastics which are environment-friendly and biodegradable. Bioplastic can be prepared from renewable resources consisting of biomass mainly starch, cellulose, etc. This paper presents a detailed process of preparation of bioplastic from corn and potato starch followed by its mechanical strength testing. Also, the real-life applications of the obtained bioplastic are discussed. The bioplastic produced initially lacks plasticity so sorbitol was added as a plasticizer. The newly prepared bioplastic has higher elongation and less water absorptivity. Hence it can be concluded that the bioplastic obtained meets the requirement to be considered as an alternative to conventional petroleum-based plastic.

AI summary Read the abstract
This review examined production mechanisms, structural modifications, and industrial applications of starch-based bioplastics for food packaging, discussing the role of plasticizers and physical and chemical treatments that enhance hydrophobicity, mechanical strength, and thermal stability. While starch-based bioplastics offer biodegradability and renewable origins supporting a circular economy, the review concluded that trade-offs with food production feedstocks and higher manufacturing costs compared to conventional plastics mean they are not a complete long-term solution to plastic pollution.
