Environmental pollution is defined as “the unfavorable alteration of our surroundings through direct or indirect effects on the chemical, physical, and biological characteristics of our air, land, and water influenced primarily by man's actions. Some of the major variables, elements of the problem, and problems related to farm animal waste management can be found in Table 1.

The article examines the concept and metaphorical meaning of waste and dirt in short folklore forms, including archival material (phrasemes, proverbs, and beliefs) and also internet memes as a new, contemporary folklore form. Waste and dirt are traditionally conceptually linked to metaphors of unwanted, used, lower-quality, or even immoral. Slovenian proverbs and phrasemes, on the other hand, do not thematize waste management or handling dirt; only beliefs show some part of this. New forms, on the other hand, emphasize environmental pollution directly, using concepts of waste and pollution combined in words and images intended to persuade the viewer or recipient to change their behavior into environmentally responsible behavior. Waste and dirt reveal themselves as important metaphorical elements, as well as a contemporary topic for new folklore genres.

The recycling of waste plastics is considered as one of the strategies to tackle the issue of environmental pollution caused by commodity plastics all over the world. Recently, many universities have incorporated topics related to recycling and plastics waste management into their curricula at different levels to increase awareness as well as to develop new recycling technologies. In this study, one of the most important waste recycling problems is given as the project for the undergraduate students of chemical engineering to analyze the effectiveness of the project-based learning (PBL) approach in the school curriculum. A team of students was assigned with the task of recycling post-consumer polyethylene terephthalate (PET) bottles through an experimental and design approach. From the experimental data, students designed a recycling plant with a proposed capacity to produce 1 ton of recycled granules per day through the project-based learning approach. Evaluation of the project was carried out at various stages and it was found that the students acquired the required skills and applied them effectively. The outcomes of the present study clearly establish that the problems which have societal impacts, such as waste management, environmental pollution, etc., can be effectively communicated to the student community through the PBL approach, which can lead to increased motivation and enhanced critical thinking abilities.
