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.

This chapter will exhibit the experience of applying project-based learning in different subject matter, identifying and comprehending the efficiency of this teaching methodology from an analysis of the activities undertaken. The subjects focused on were transport phenomena and unit operations in chemical processes. The methodology of project-based learning is to associate concepts acquired during classes and integrate them with other subjects in order to integrate the parts into the whole. It develops a variety of skills in addition to technical ones, such as cooperation, communication, involvement, knowledge construction, decision making and problem solving. All these skills being supported by the use of distance education tools. The creation of the subjects in a virtual environment sustains student materials previously required for project development. It also monitors of student activity (access by frequency statistics), and facilitates communication. The motivation and interactivity aspects have been shown to be positive with students and professors systematically involved in the constructive evolution of both individual and group knowledge.

With rapid population growth, especially in low-income and middle-income countries, the generation of waste is increasing at an unprecedented rate. For example, annual global waste arising from waste electrical and electronic equipment alone will have increased from 33.8 to 49.8 million tonnes between 2010 and 2018. Despite incineration and other waste treatment techniques, landfill still dominates waste disposal in low-income and middle-income countries. There is usually insufficient funding for adequate waste management in these countries and uptake of more advanced waste treatment technologies is poor. Without proper management, many landfills represent serious hazards as typified by the landslide in Shenzhen, China on 20 December 2015. In addition to formal waste recycling systems, approximately 15million people around the world are involved in informal waste recycling, mainly for plastics, metals, glass and paper. This review examines emerging public health challenges, in particular within low-income and middle-income countries, associated with the informal sector. While informal recyclers contribute to waste recycling and reuse, the relatively primitive techniques they employ, combined with improper management of secondary pollutants, exacerbate environmental pollution of air, soil and water. Even worse, insufficient occupational health measures expose informal waste workers to a range of pollutants, injuries, respiratory and dermatological problems, infections and other serious health issues that contribute to low life expectancy. Integration of the informal sector with its formal counterparts could improve waste management while addressing these serious health and livelihood issues. Progress in this direction has already been made notably in several Latin American countries where integrating the informal and formal sectors has had a positive influence on both waste management and poverty alleviation.

Community engagement is a phenomenon that has received increasing attention among institutions of higher learning in recent years, and students engaging with communities are generally seen as beneficial. Given this, surprisingly little is known about this form of engagement in Australian higher education, let alone methods to measure its benefits on students. This study discussed the development of the Student Community Engagement Benefits Questionnaire (SCEBS), a questionnaire that measures the perceptions of community engagement benefits among undergraduate students in Australia. The final questionnaire has 32 items allocated to four benefit scales: (1) Career skills, (2) Diversity skills, (3) Interpersonal skills, (4) Civic skills. Most benefit items had a factor loading of atleast 0.40 with its own scale. The results of the factor analysis revealed that the four scales accounted for 53% of the total variance. The alpha reliability coefficient for the four scales ranged from 0.79 to 0.91. Based on these findings, the Student Community Engagement Benefits Scale (SCEBS) is a valid and reliable instrument that can be used in the field of education. Undergraduate students also reported statistically significant changes in the four dimensions after participating in community engagement activities.
