Food Waste Treatment Systems
Our food waste treatment systems provide a completely integrated, customized solution for commercial kitchens, central kitchens, hotels, food-service facilities, and waste-management operators.
The system combines pre-sorting, crushing, screening, dewatering/pressing, and phase separation to ensure a minimum loss of organic content and oil, reducing wear on equipment with an effective separation of mixed materials.
It provides clients with volume reduction, cost savings, compliance with environmental regulations, and quick return on investment by enabling safe, efficient on-site food-waste pretreatment that integrates seamlessly with downstream resource-recovery processes such as anaerobic digestion.

Comprehensive Food Waste Treatment System – Food Waste Wet Anaerobic System
Due to the gradual implementation of waste sorting across the country, we designed two separate wet anaerobic food waste treatment systems customized to the relevant regional cultures.
1. Food Waste Pre-Sorting System for Wet Anaerobic Digestion
- This system was designed with the northern arid cities in mind, as it focuses on the treatment of large-scale kitchen waste.
- It employs a storage pit feeding method with the core process being grab feeding, screening, shredding, dewatering and pressing, and wet anaerobic digestion.
- Major advantages are the small degree of organic matter loss, low water consumption, high processing capacity, and lower chances of material blockage.
2. Pre-sorting System for Kitchen Waste Suitable for Wet Anaerobic Digestion
This system has been developed for kitchen waste management in humid southern regions with a mature infrastructure of waste sorting. It boasts direct vehicle loading and provides single-line processing with medium throughput.
The core process consists of direct vehicle loading → coarse crushing → screening → pulping & pressing → wet anaerobic digestion. The above work process can efficiently reduce and stabilize kitchen waste, provide relatively higher water use due to process characteristics, and realize the maximum recovery of organic resources for energy and material reutilization.
Key Features and Benefits of Food Waste Treatment Systems
Our food waste treatment systems technology overcomes the inherent difficulties of traditional food waste pretreatment (i.e., rapid loss of organics & fats, high wear rate on processing equipment, and contamination of the input) by providing reliable and efficient processing of food waste, as well as overcoming the difficulty of consistent separation of the classes of materials
- Effective primary treatment: ensures loss of organics and fats is lower, as is wear on processing equipment
- Complete design of the target processing system: enables complete processing of food waste to be performed on site ( filtration, crushing, screening, pulping and pressing, heating and buffering, three-phase separation)
- Exploitation of waste resources: enables safe, compact, and legal disposal of food waste and the subsequent anaerobic digestion processing of the digestate
- Economic Benefits: Reduction of costs and rapid return on investment due to savings on operating costs and environmental costs.
