Abstract

Waste management investigation addresses the pressing necessity to adopt sustainable waste management approaches, examining the efficacy of ensemble learning techniques and refined CNNs for waste categorization, encompassing both organic and recyclable materials. The investigation utilizes the "waste-classification-data" dataset containing 25,000 images to fulfill the current research requirement for extensive, balanced datasets essential for robust model development. The pre-trained architecture ResNet50 underwent transfer learning optimization, while SMOTE and ENN were applied for class balancing, indicating their environmental application potential. To enhance classification capabilities, a majority voting ensemble approach was implemented, integrating predictions from these optimized models and surpassing individual model performance while aligning with recent advancements in ensemble learning methodologies. The integration of transfer learning with ensemble techniques has proven effective in achieving precise waste classification outcomes, offering an automated and expandable waste sorting solution that contributes to minimizing plastic waste's environmental consequences. The research is supported by empirically informed implementation concepts and enhancement strategies, concluding that meticulously calibrated CNNs exhibit significant resilience against real-world waste management challenges and represent a valuable contribution to recycling system advancement and the promotion of sustainable waste handling practices.
