Food waste, also known as drowning water, food residues, food and kitchen residues, etc. Now people's awareness of environmental protection has increased. The disposal of food waste has always been a concern for people. The content of organic matter in food waste is high, about more than 95% of dry matter. It is easy to corrupting and stinking, and breed bacteria, causing the disease spread. Especially in the summer, secondary pollution can easily occur during collection and transportation. However, in addition to the high content of organic matter in food and kitchen waste, it is also rich in protein, nitrogen, phosphorus, potassium, calcium, and various trace elements. It has the characteristics of complete nutrition elements and high recycling value. Jiutian food waste drying plant use of food waste as a comprehensive utilization of resources not only avoids the resources waste but also makes the resources reused and turns waste into treasure.

Three main paths for the comprehensive utilization of food waste

1. Make the kitchen waste as protein feed. The food waste through sorted, impurities are removed, crushed, dehydrated, deoiled, and oil recovered, biomass diesel is produced, and yeast, probiotics, and auxiliary materials are added. After aerobic fermentation, drying, cooling, packaging, wastewater, and waste gas pass through to meet the discharge standards, the final product is protein feed and biomass diesel.

2. Process kitchen waste as organic fertilizer. Food waste is sorted, impurities are removed, and crushed, dehydrated, deoiled, oil is recovered. To produce the biomass diesel, it needs to add yeast, enzyme preparations, and auxiliary materials. After aerobic fermentation, drying, cooling, packaging, wastewater, and waste gas process to reach the discharge standards, the final product is an organic fertilizer and biomass diesel. 

3. Use kitchen waste to product biogas. After the sorting of kitchen garbage, impurities removed, crushed, deoiled, and oil recovered and adds anaerobic bacteria. In the sealed tanks, anaerobic fermentation is used to produce biogas for power generation or combustion, and waste residues are dehydrated, drying, cooling, and packaged, and the wastewater is treated and discharged up to standard. The final products are biogas, organic fertilizer, and biomass diesel.
