Abstract
The agricultural sector in Uzbekistan generates significant amounts of organic waste, which currently leads to environmental pollution and inefficient resource use. This study aims to evaluate the potential of innovative processing methods for agricultural waste through simulation modeling and mathematical analysis. The research focuses on four main types of agricultural residues: wheat straw, leguminous crops, vegetable waste, and fruit residues. Using statistical data from 2024 and international literature on waste composition, we developed a simulation model to estimate the potential for compost production and bioenergy generation via anaerobic digestion. The results indicate that vegetable waste holds the highest potential for both compost (8,396 thousand tons) and bioenergy (23,000 GWh), followed by wheat straw and fruit residues. The study also calculates the nutrient content (nitrogen, phosphorus, carbon) of the resulting compost, demonstrating its potential to enhance soil fertility. Compared to traditional disposal methods such as burning or landfilling, the proposed processing methods significantly reduce carbon footprint and contribute to energy savings. This research provides a scientific basis for the sustainable management of agricultural waste in Uzbekistan and offers practical recommendations for the implementation of centralized composting and biogas production facilities.
