Prioritized and predictive intelligence of things enabled waste management model in smart and sustainable environment

Abstract

Collaborative modelling of the Internet of Things (IoT) with Artificial Intelligence (AI) has merged into the Intelligence of Things concept. This recent trend enables sensors to track required parameters and store accumulated data in cloud storage, which can be further utilized by AI based predictive models for automatic decision making. In a smart and sustainable environment, effective waste management is a concern. Poor regulation of waste in surrounding areas leads to rapid spread of contagious disease risks. Traditional waste object management requires more working staff, increases effort, consumes time and is relatively ineffective. In this research, an Intelligence of Things Enabled Smart Waste Management (IoT-SWM) model with predictive capabilities is developed. Here, local sinks (LS) are deployed in specified locations. At every instant, the current status of smart bins in each LS is notified to users to determine the priority level of LS to be emptied. Based on aggregated sensor values for the three smart bins, LS weight and poison gas value, the priority order of emptying LS is computed, and decision is made whether to notify the users with an alert message or not. It also helps in predicting the LS, which is likely to be filled up at a faster rate based on assigned timestamp. This model is implemented in real time with many LS and it was observed that bins, which were close to more crowded sites filled up faster compared to sparse populated areas. Random forest algorithm was used to predict whether an alert notification is to be sent or not. An average mean of 95.8% accuracy was noted while using 60 decision trees in random forest algorithm. The average mean execution latency recorded for training and testing sets is 13.06 sec and 14.39 sec respectively. Observed accuracy rate, precision, recall and f1-score parameters were 95.8%, 96.5%, 98.5% and 97.2% respectively. Model buildup and the validation time computed were 3.26 sec and 4.25 sec respectively. It is also noted that at a threshold value of 0.93 in LS level, the maximum accuracy rate reached was 95.8%. Thus, based on the prediction of random forest approach, a decision to notify the users is taken. Obtained outcome indicates that the waste level can be efficiently determined, and the overflow of dustbins can be easily checked in time

Does environmental regulation lessen health risks? Evidence from Chinese cities

“…Specifically, by promoting major technological innovations and transformative applications such as ecological product design, cleaner production processes, utilization of industrial linkages, and coordinated regional waste disposal and utilization, the advancement of science and technology facilitates the reduction of pollutants at the source and supports the efficient recycling and utilization of resources at multiple levels ( 51 ). In addition, real-time monitoring and analysis of air quality, pollution sources, and emissions can be achieved using scientific and technological means such as digital techniques, remote sensing techniques, and artificial intelligence, which provide data support for the formulation of scientific and reasonable environmental standards and policies and improve the accuracy and effectiveness of environmental regulation ( 52 , 53 ). Additionally, these methods contribute to the early identification and punishment of unlawful emissions, thus strengthening environmental regulation, enforcement, and supervision ( 54 ).…”

Cybersecurity considerations in the implementation of innovative waste management technologies: "A critical review"

“…The future of waste management lies in leveraging these technologies to predict waste generation patterns, optimize collection routes, and enhance the overall security of waste management systems. Mishra et al (2022) present an innovative model that combines the Internet of Things (IoT) with AI to create a predictive waste management system. This system utilizes sensors to monitor waste levels in bins and employs AI algorithms to predict when bins will be full, thereby optimizing collection schedules and routes.…”

“…The model demonstrates a significant improvement in operational efficiency and resource allocation, reducing the time and effort required for waste collection. Furthermore, the predictive capabilities of this model can enhance the security of waste management systems by preventing overflows and ensuring timely collection, thereby mitigating health risks associated with accumulated waste (Mishra et al, 2022). Allahham et al (2023) explore the application of big data analytics and AI in improving the sustainability of hospital supply chains, which includes waste management.…”

Research on the Application of Random Forest-based Feature Selection Algorithm in Data Mining Experiments

“…The research in [29][30][31][32][33][34] examines the efficacy of ML algorithms like RF and its variations in selecting Single Nucleotide Polymorphisms (SNPs) for fine-scale genetic population assignment in wildlife conservation. The study, which uses unpublished data for Atlantic salmon and published data for Alaskan Chinook Salmon (ACS), found that ML methods outperformed traditional Fixation Index (FST) rankings in identifying informative genetic markers.…”
