摘　　要：The replacement of fossil raw materials by renewable alternatives is imper­ative.Renewable,biodegradable,and compostable polymers are options to be developed and adopted.Embedded in this concept,the present study evaluates whether biopolymers are sustainable alternatives to replace tra­ditional polymers used in packaging,such as polyethylene.To that end,a systematic literature review(SLR)was carried out on biopolymers applied to packaging,with an analysis of its impacts.Three sustainability crite­ria were adopted:a)Criteria for Developing Sustainable Packaging;b)Goals of Sustainable Development;and c)Circular Economy Criteria.The Methodology Section presents the state of the art of potential polymers for packaging and their characteristics related to the evaluation criteria adopted based on the SLR.Through data collection,it was observed that advanced obtaining techniques enable polymers economically and that,environ­mentally speaking,there is a positive consensus about some types of those materials.However,technological maturity and productive scale capacity are necessary to reduce costs in a competitive scenario with conventional polymers.
