For our kitchen waste processing plant, there are 2 techniques available to deal with the kitchen waste:

This technique for processing kitchen waste can be divided into 3 parts: pretreatment, aerobic composting, and supporting steps. The processing system is composed of various subsystems: storage system, primary sorting system (magnetic separation), pre-crushing system, automatic crushing and sorting system, intermediate storage and mixing system, dewatering systems, mixing systems, aerobic fermentation systems, conveying systems, oil and water separation systems, deodorization systems, crushing and sorting systems, and electrical control system, etc.

Advantages
1. The waste processing plant covers only small area
2. The 1st and 2nd fermentation process is done completely inner the reaction tank to isolate the stench
3. The feeding and discharging is conducted continuously and automatically
4. The fermentation conditions are met only with the min oxygen consumption
5. It is in no need to stir the materials for high-temperature fermentation. The failure rate is low
6. Only little amount of water conditioning agent is consumed for mature composting
7. Convenient feeding and discharging

a. Pretreatment
Sorting machine is equipped for this line to separate out the non-degradable inorganic materials in the kitchen waste. The recyclable materials will be recycled.

b. Oil-Water Separation System
Thiswaste recycling equipment is set to separate oil, water, and residue. The separated oil can be used for chemical materials or biodiesel.

c. Biogas Production System (anaerobic environment)
Microorganism is utilized to decompose the organic in chemical waste. The biogas produced in the anaerobic fermentation process will be applied in generating electricity or vehicle fuel.

d. Biogas Slurry and Residue Treatment
The biogas slurry will be released after being processed with a water treatment system, and the biogas residue can be used to produce efficient organic fertilizer after a composting treatment.

Final products of this technique: compressed natural gas (CNG) for vehicle fuel, organic fertilizer, biogas slurry

Advantages
1. Resource Maximization
This food waste recycling plant is especially targeted at municipal kitchen waste, recycling the food waste to the max extent

2. High Product Quality
The pretreatment system supports the final organic fertilizer to reach the standards for agricultural fertilizers, meeting the requirements of green organic fertilizer market

3. High Automation
All of the operations are finished automatically, considerably reducing the bad influence upon environment and people

4. Environment-Friendly
The system is fully enclosed so there is no stink leaked.

5. High Efficiency
This waste processing plant is equipped with a unique anaerobic fermentation tank, ensuring the system's stability and high gas output. Gas mixing method is employed. It is easy-operated and asks for no maintenance.

6. Large Market Demand
The renewable resource (biofuel, electricity, thermal) produced in the food waste recycling process is a reliable solution for energy shortage.
