The article brings to attention a cross cultural model related to the perception of students in relation to the current problem of plastic waste. To create the model, a questionnaire was applied online in two countries at the same time, among students from different specializations. The survey was structured in several parts, with the first part meant to identify individual characteristics of the responders, the second part to identify their knowledge about plastic, determine their beliefs in the new material—bioplastic, their preference in using plastic or bioplastic, and the last part meant to determine students’ attitude towards the environment. The model wants to highlight the preferences and knowledge of students about plastic, the degree of information and students’ knowledge about plastic waste, and if these are influenced by culture; in our case, the country was considered. Also, we established that gender or specialization have no influence on the perception of bioplastic. A total of 39.79% of the students from both countries participate in and attend conferences about nature protection and plastic waste, and only 58.69% of the students do not participate in any conferences about nature conservation or recycling materials. As a conclusion, we can mention that Turkish students are more responsible and more active in environmental activities regarding plastic waste in comparison with Romanian students. In comparison with Romanian students, Turkish students are more careful when it comes to recycling waste plastic and when choosing products that are less harmful to nature. The young generation is open to selective recycling, even if they sometimes do not follow the established rules. Based on this model, common problems can be identified and universities, as incubators of ideas, can welcome the use of the necessary methods and tools to stimulate care and students’ awareness of the environment and its protection.
