Advanced predictive modeling of municipal solid waste management using robust machine learning.

Urbanization and technological advancements have exponentially increased municipal solid waste (MSW) volumes, necessitating advanced predictive frameworks beyond traditional collection-disposal approaches. This study addresses this gap by integrating robust machine learning (ML) techniques-specifically Convolutional Neural Networks (CNN), Support Vector Machines (SVM), Multilayer Perceptrons (MLP), and Logistic Regression (LR)-to optimize municipal solid waste management (MSWM) forecasting and strategic planning. Methodologically, a structured nine-step workflow was employed, encompassing data collection, preprocessing, model development, and validation using statistical metrics (ARE, AARE, RMSE, R2). A comprehensive Kaggle-sourced dataset of 4,341 records (3,300 for training/testing, 1,041 for validation) was analyzed, featuring 20 variables including population density, waste composition, and geographic factors. Results demonstrated CNN's superior accuracy across all datasets: training (R²=0.999, RMSE = 0.81), testing (R2 = 0.996, RMSE = 1.01), and validation (R2 = 0.996, RMSE = 0.53), outperforming SVM, MLP, and LR. CNN's ability to model nonlinear relationships and handle data irregularities enabled precise waste generation predictions, enhancing route optimization, resource allocation, and policy formulation. ML's role in MSWM is transformative, shifting systems from reactive to proactive management while balancing environmental sustainability and operational efficiency. The novelty of this work lies in pioneering CNN for MSWM prediction-a first in this domain-and its regularization strategies to minimize overfitting.
