Section:: TECHNICAL NOTE

The production of plastic materials in 2016 was approximately 280 million tons, of which about 75% were disposed of in landfills. The constant accumulation of this type of waste has caused negative impacts on flora and fauna due to its low biodegradability. As an alternative to this complex problem, this work proposes the formulation of biopolymer mixtures based on polylactic acid (PLA) and native starch, as a viable option to minimize the impact caused by conventional plastics.
