Abstract

Modern chemistry teaching faces the challenge of interpreting complex environmental issues through the lens of scientific facts. This paper presents a methodological model for introducing green chemistry into the fourth grade of grammar school, using the synthesis of polylactide (PLA) as the central experimental focus. Instead of theoretical instruction on polymers, students participate directly in laboratory work, transforming lactic acid into biodegradable plastic.

The lecture focuses on the application of the 12 principles of green chemistry, with particular emphasis on the use of renewable resources and the design of materials for easy degradation. The results of the conducted educational workshop indicate a significant increase in students’ chemical literacy and critical thinking, while simultaneously developing awareness of sustainable solutions to the problem of microplastic accumulation. Participants will gain insight into an optimized laboratory protocol adapted to school conditions, as well as evaluation sheets for measuring learning outcomes within the domain “Chemistry and Society.”

Green chemistry represents a modern approach to chemistry that emphasizes the development of processes and products with minimal negative impact on the environment and human health. It is based on twelve principles that promote waste reduction, the use of safer substances, energy efficiency, and the use of renewable feedstocks. Unlike environmental chemistry, which focuses on monitoring and analyzing pollution, green chemistry aims to prevent pollution at its source, at the very beginning of the chemical process.

The development of green chemistry has been driven by growing environmental challenges such as climate change, pollution, and the depletion of natural resources. Although some industries, such as petroleum refining, are effective in reducing waste, their products and processes still have a significant negative impact on the environment. Therefore, there is an increasing emphasis on the development of sustainable, carbon-neutral technologies and alternative production methods.

Education plays a particularly important role, as future chemists must develop a sense of responsibility toward the environment and society. Introducing the principles of green chemistry into the education system fosters innovation, the development of safer products, and the application of environmentally friendly technologies. Despite challenges such as financial constraints and a lack of training, progress in this field depends on continuous investment in knowledge, research, and industrial innovation.

Green chemistry is also becoming a key tool for achieving sustainable development, connecting science, the economy, and environmental protection. Its future lies in the responsible actions of individuals and society as a whole, with the aim of preserving the planet for future generations.
