Organic Fertilizer Raw Material Pretreatment: From Wet and Sticky Waste to Fermentation Substrate
In organic fertilizer production, raw material pretreatment is the “first hurdle” determining subsequent fermentation efficiency and granulation quality. Livestock manure, straw, sludge, and other raw materials often have high moisture content, long fibers, and many impurities. Without scientific treatment, they can lead to uneven fermentation or even damage to equipment. A complete raw material processing solution, encompassing four major stages—crushing, impurity removal, dehydration, and mixing—can transform the originally messy waste into a uniform and loose fermentation substrate.
