    The prevalence of polyethylene terephthalate (PET) in beverage packaging has increased microplastic (MP) accumulation in the environment. MP can become a component of air pollution, especifically of particulate matter with a diameter of less than 2.5 microns (PM2.5). Unfortunately, Thailand has a low recycling rate for plastic bottles, with only 4.5% being recycled. Reverse Vending Machines (RVMs) were introduced in the early 2010s as a potential solution to this problem. RVMs incentivize recycling by providing rewards or refunds for each bottle deposited, thereby reducing the amount of PET waste and MP in the environment. This study analyzed usage and waste collection data from RVMs located at 15 locations of a hypermarket chain in Thailand from June 2020 to December 2022. The results showed that the average PET bottles collected from each machine was approximately 670 kg per year, which was lower than the break-even point of 3,200 kg per year. Economic feasibility indicators also suggested that the use of RVMs might not be economically sound. This study proposed suggestions to improve the business model of RVMs and offered policy recommendations to the government on how to enhance the effectiveness of RVMs.

    Development of an assessment tool for prioritizing influencing factors of sustainability in higher education

    The United Nations set 17 Sustainable Development Goals (SDGs) in August 2015 as a blueprint to achieve sustainable future for all nations at all levels. Higher education institutions are expected to significantly contribute to the goal, as they must produce the human resources and research necessary for achieving sustainability. In October 2019, Times Higher Education (THE) launched the THE University Impact Rankings, which encouraged universities to focus efforts that pose positive impacts on SDGs in the areas related to the university's operation. Since SDGs and their targets may have different priorities in different countries, we examined the perspectives of stakeholders in 16 Thai universities ranked in the THE World University Rankings to prioritize the SDG areas on which the universities should focus. We expect that this study will be used by Thai university executives to optimize resources spent on achieving better sustainability performance.

    Systems thinking is normally accepted as the backbone of a successful systems approach and understanding the big picture. Systemigrams help system engineers map the relation between members in the systems of interest (SOI) and provide text and pictures that were drawn on a map, so Systemigrams are used to present a picture of the whole system or present individual system components and contexts in a supply chain system. Moreover, a systems approach shows the full perspective of a business architecture and links the vision of the organization into real action. In summary, a business architecture could transform business processes in each department of a university from manual processes to more productive automated processes. In this study, we have drawn Systemigrams and a designed framework to bring the value through the education supply chain with a digital business process. This study can provide a framework to implement a digital supply chain transformation in a typical Thai university, KMITL, and then we apply it to the other tertiary education institutions and the other service business sectors in Thailand and similar countries.
