The master's thesis explores the attitudes and knowledge of primary school students regarding
bioplastics, biodegradable plastics and the differences between these materials and conventional
plastics. The aim of the research was to determine how students, age 12 to 15 understand the
terms bioplastic and biodegradable plastic, with an emphasis on environmental aspects of their
use, degradability, and their impact of these materials on the environment.
The empirical part of the research is based on a quantitative study conducted through a
questionnaire among students from different primary schools. The questionnaire examined their
understanding of the differences between different types of plastics, their evaluation of
environmental and functional properties, and their attitudes toward the use and degradation of
plastics. Participants answered questions about the proper disposal of biodegradable plastics, the
environmental impact of materials and their own behavior regarding plastic use in everyday life.
The results show that students often do not distinguish between the concepts of bioplastic and
biodegradable plastic, with many incorrectly assuming that the two are synonymous or that all
bioplastics are biodegradable. Nevertheless, they demonstrate a high level of environmental
concern and a positive attitude toward finding more sustainable alternatives. Most students
support the wider use of biodegradable plastics but are not willing to pay more for them. They
perceive products made from conventional plastics as having a greater negative environmental
impact compared to bioplastic or biodegradable alternatives.
The thesis highlights the need to include clear, scientifically supported and didactically adapted
content about modern materials in the school curriculum. Special attention should be given to
understanding environmental concepts, developing critical thinking, and connecting everyday
habits with their environmental impact. With appropriate knowledge, young people can develop a
responsible attitude toward plastic use and waste management and contribute to reducing
pollution.
