| Abstract |
There is a demand for new technologies to replace fossil resources in activities due to environment concerns. In the circular economy, materials to be discarded are reused and reenter to the economy. An alternative for the plastic problem would be preparation of fiber-reinforced plastics from renewable sources. Herein polymeric films were prepared with starch, glycerol and bagasse derivatives. Some characterization techniques were presented to indicate the best applications. It was identified that higher glycerol ratio films are more malleable and have a higher humidity and solubility. The DSC scans for each film shows no increase in glass transition temperature. Biodiesel films are an alternative for the circular economy of waste and the biodiesel industry, since the study proved to be an alternative for the plastics currently used. This work will certainly attract the students' interest, because the theme is in their daily lives, also bringing the precepts of sustainability and green chemistry. |
