Waste control in organic fertilizer production lines is directly related to production costs and product returns. Optimization plans must be developed throughout the entire process, from raw material processing to finished product storage, to minimize material waste and energy consumption.

Raw material pretreatment is the starting point for waste control. Raw materials such as livestock and poultry manure and straw must first be screened to remove impurities such as stones and plastics to prevent them from wearing out equipment or contaminating the finished product, leading to rework. Furthermore, a precise batching system should be used to mix raw materials according to the formula ratio to avoid waste caused by manual batching errors. Raw materials can be chopped to a uniform particle size before mixing, improving subsequent fermentation efficiency and reducing material waste due to incomplete fermentation.

Production process optimization is key to reducing waste. Temperature, humidity, and ventilation must be strictly controlled during the fermentation process. Excessively high temperatures can easily lead to carbonization, while excessively low temperatures can lead to incomplete fermentation. Automatic temperature control systems can be used to adjust temperatures in real time to ensure a fermentation conversion rate of at least 85%.

Maintenance of organic fertilizer equipment and storage of finished products are also crucial. Regularly inspect and maintain conveyor belts and seals on conveying equipment to prevent material leakage during transport. Retrofit insulation to drying equipment to minimize heat loss and energy consumption. For finished product storage, use moisture-proof, ventilated warehouses, maintain reasonable stacking heights to prevent crushing of bottom-level particles, and install material sorting shelves to prevent product mix-ups and losses. Through refined management of the entire process, losses in the organic fertilizer production line can be significantly reduced, improving overall production efficiency.
