Polymer-based plastic materials derived from fossil fuels are widely used in various sectors, particu-larly agricultural production; however, this leads to serious environmental pollution problems. The increase in solid waste, particularly caused by plastic-based seedling and plant growing media, contra-dicts sustainable agriculture goals. This study aimed to produce biodegradable growing media from organic waste such as agricultural harvesting and threshing waste and poultry litter using square molds. The production process was carried out using a computer-controlled, 100-ton capacity hydraulic press, which used square molds. The resulting products were subjected to various tests for soil solubility, physical strength, and environmental compatibility. The study aimed to contribute to sustainable agri-cultural production systems by presenting an innovative approach to reducing the use of fossil-based plastics.
