Background: The COVID-19 pandemic has increased the need for mask production which has caused the problem of mask waste generating in the environment without being managed. This research was conducted to determine the relationship between knowledge, attitudes, and sociodemographic factors with college student behaviours in managing household mask waste in Daerah Khusus Ibukota (DKI) Jakarta Province.
Methods: This study used a quantitative approach and cross-sectional study design. Data collection was carried out using an online questionnaire consisting of the respondents' sociodemographic, knowledge, attitudes, and behaviours.
Results: The majority of students had high knowledge (63.3%), positive attitudes (52.5%), and good behaviours (50.6%). Statistically, there was a significant relationship between knowledge and behaviours (p = 0.022), but there was no significant relationship between attitudes and behaviours (p = 0.269). In addition, the sociodemographic factor variables showed a significant relationship between place of residence and behaviours (p = 0.008). However, there was no significant relationship between age, gender, education, and study program groups and behaviours (p > 0.05). Multivariate analysis showed that living with family was a dominant factor for bad behaviours (OR 1.664, 95% CI=1.124-2.464), and the second risk factor was the low level of knowledge has a significant relationship with the behaviours of mask waste management at home (OR=1.559, 95% CI=1.044-2.330).
Conclusions: Students who live alone also show better behaviour compared to students who live with their families. The place of residence variable has the greatest influence on the behaviour of mask waste management at the household, followed by the knowledge variable.

The accumulation of disposable face masks (DFMs) has become a significant threat to the environment due to extensive use during the COVID-19 pandemic. In this research, we investigated the degradation of DFMs after their disposal in landfills. We replicated the potential degradation process of DFMs, including exposure to sunlight before subjecting them to synthetic landfill leachate (LL).

The export ban on plastic waste by China has brought domestic plastic recycling to the forefront of environmental concerns, with sorting being a crucial step in the recycling process. This study assessed the performance of advanced AI models, Mask R-CNN, and YOLO v8, in enhancing plastic waste sorting. The models were evaluated in terms of accuracy, mean average precision (mAP), precision, recall, F1 score, and inference time, with hyperparameter tuning performed through grid search.

During the COVID-19 pandemic, face masks, as personal protective equipment (PPE) against the coronavirus (SARS-CoV-2), have been widely used worldwide. How to properly dispose of used PPE has brought a huge challenge to the ecosystem and human health. Here we proposed a laser flash pyrolysis (LFP) strategy to upcycle the used polypropylene(PP) face mask to vinylidene-terminated PP wax (PP-VDT) and further functionalized for compatibilizer application.

This research presents an experimental analysis of the mechanical behavior of masonry mortars incorporating disposable face masks (FMs) cut into two different sizes. The objective is to provide experimental data contributing to the consolidation of recycling FMs in mortar mixtures. To achieve this, two types of mixtures were prepared: one with strips of 3 × 3 mm and another with strips of 3 × 10 mm.
