Development of a Laboratory Module in Hybrid Biodegradable Thermoplastic Cornstarch Materials “Green Plastics Manufacturing Technology” (GPMT) is an emerging discipline thatencompasses a range of activities, from the research and development of non-toxic, eco-friendly materials to the reduction of waste and elimination of pollution through changingpatterns of production and consumption. Because of advances in technology and the growingdemand for environmentally friendly products, materials science and manufacturingtechnology has become an increasingly important component of today’s engineering andtechnology education. There is a global interest in replacing petroleum based synthetic composites with biodegradable hybrid material systems in order to use renewable resources and to reduce theamount of persistent non bio degradable plastics waste. Fillers (or reinforcements) playimportant role to improve various characteristics in hybrid reinforced composites. Inorganicfillers are commercially used to modify the properties of composites in industry for manydecades. The primary study attempts to investigate the effects of various types of inorganicfillers (such as halloysite nano clay and calcium carbonate (CaCO3)) on the thermal (TGAand DSC) and mechanical properties (tensile and impact testing) of hybrid thermoplasticcornstarch materials. The results of the investigation lead to developing a laboratory modulein hybrid biodegradable materials for undergraduate materials curriculum in theManufacturing, Mechanical Engineering Technology/Packaging Science at RochesterInstitute of Technology (RIT). Undergraduate students can learn green materials technologyin a hands-on, project based format, working in teams to carry out lab assignments that focuson eco-friendly materials and product development. Some outcomes and assessment of thestudy will be addressed as well.
