Aplication of delphi method in a foresigth study on biodegradable packaging up to 2032

Delphi methodology was chosen to perform a foresight study up to 2032 in biodegradable packaging and environmentally friendly products. To develop the study, a questionnaire with 196 variables classified into 5 areas was elaborated: Technological innovations, commodities for biodegradable polymers production, commodities for biodegradable packaging production, additives and technologies, the questionnaire was sent to 92 national and international people with knowledge on the topic. The expert panel was made up of 30 people who gave response to the questionnaire for three rounds. According to statistical analysis raised, in the first round, 51 priority variables and 140 variables under discussion were obtained, the 5 variables remaining were classified as non-priority. In the third round, a total of 78 prioritized variables were obtained. The results obtained in the area of technological innovations, natural coatings, active packaging and smart packaging, were considered priorities during the three rounds. In the area of commodities for the production of biodegradable polymers, the potato, cassava and corn starch were considered a priority, in addition to Agroindustrial wastes and in the technology area, reactive extrusion, blow molding and extrusion injection molding were kept for three rounds as priority variables.
