WANROOETECH delivers end-to-end food waste recycling solutions that transform organic refuse into renewable resources. Our integrated systems handle the complete treatment workflow—sorting, shredding, dewatering, degreasing, oil extraction, anaerobic fermentation, biogas recovery, and biomass briquetting. By processing kitchen waste alongside sludge, straw, and other biomass materials, we enable facilities to achieve zero-waste targets while producing clean-burning fuel with zero secondary emissions. It’s resource recovery engineered for the circular economy.

What is food waste?

Food waste encompasses all organic byproducts of food preparation and consumption—rice and flour residues, vegetable scraps, animal and vegetable oils, meat, bones, and more. Left untreated, this waste decomposes rapidly, releasing foul odors, harboring pathogens, and threatening both food safety and environmental health.
Its composition is inherently heterogeneous: a challenging blend of oils, water, peels, vegetables, rice, flour, fish, meat, bones, and other organic compounds that demand specialized processing equipment.

Why should I recycle food waste?

Food waste disposal not only recovers resources and gives a second life, saves landfill space and eliminates environmental pollution, it also greatly reduces the volume of waste and daily disposal and organic waste can be disposed of in a neat and tidy manner. Food waste recycling machines are ideal for communities, restaurants, offices, schools, food markets, farms and other facilities that generate organic waste on a regular basis.

How is food waste recycled?

WANROOETECH offers two proven treatment pathways, with shredding and dewatering as the universal first step:
Biological Treatment: Shred → Dehydrate → Microbial Fermentation → High-value Fermented Feed
Physical Treatment: Shred → Dehydrate → Dry & Disinfect → Premium Dry Feed
Pre-shredding and dewatering accelerate fermentation kinetics and cut total processing time significantly.
Engineered for real-world conditions, our systems handle both high-moisture catering waste and dry food scraps. Treated output is immediately ready for disinfection and microbial fermentation.
The WANROOETECH Process in Action:
1.Primary Shredding: Food waste is reduced to uniform 3–8mm granules
2.Spiral Conveying & Rinsing: Granules are flushed and transported to the rinsing tank
3.Spiral Extrusion Dewatering: Moisture is mechanically removed, achieving up to 80% volume reduction
4.Value Recovery: Dehydrated residue becomes organic fertilizer, biogas digester feedstock, or protein-rich feed for black soldier fly larvae
The dewatering stage is critical—it eliminates summer odor proliferation, suppresses mosquito breeding, and transforms waste into marketable commodities.

Material receiving system

Food waste recycling machine sets a material receiving system, including receiving hopper and bottom delivery chain board and spiral conveyor. Catering garbage materials are evenly sent to subsequent sorting and processing systems. In the receiving bucket, the steam jet tube can be increased. It can quickly heat the garbage according to needs, so that more oils in the garbage melt into a liquid state, flow out with water and collect for oil-water separation.

Features:

This device adopts a fully sealed structure and can process 10-30 cubic meters of kitchen waste at a time, effectively suppressing the spread of odors and providing pre-treatment buffering. Built in solid-liquid separation system optimizes the characteristics of organic logistics, reduces subsequent processing load, and increases unit production capacity. The main body adopts 304 stainless steel and hot-dip galvanizing process to ensure corrosion resistance. The modular chain drive device supports rapid maintenance and reduces operation and maintenance costs. The equipment has wide applicability and can efficiently process various types of organic waste such as kitchen, fruits and vegetables.

Chain plate conveyor

Features:

1. Strong conveying capacity, can convey 5~15 tons of materials per hour.
2. A wide range of materials can be used, whether it is food and beverage waste with high water content or food waste with large pieces, it can be conveyed efficiently.
3. The chain plate adopts mesh design, which can filter water during the conveying process for high wet food and beverage waste and provide convenience for subsequent processing.
4. All are made of 304 stainless steel, durable and corrosion-resistant.
5. As food waste has a strong corrosive, the traditional belt conveyor conveyor belt very easy to age deformation, and slipping phenomenon, stainless steel chain plate is a good solution to this series of problems, with simple maintenance, low failure rate.

Automatic Sorting Equipment

Features:

The automatic sorting equipment for food waste adopts a fully sealed structure design, which achieves efficient separation of large-sized debris such as plastic bags and glass bottles and cans through mechanical sorting modules. The equipment is equipped with a spiral conveying feeding system, which can adapt to the continuous treatment needs of kitchen waste and ensure uninterrupted operation of sorting operations. The main structure is made of a composite material of stainless steel and galvanized steel pipes, which combines corrosion resistance and structural strength, effectively extending the service life of the equipment. The sealed cabin design, combined with a negative pressure deodorization system, significantly reduces the spread of odors during the operation process, making it suitable for centralized treatment of food and beverage waste.

Food Waste Shredder

Food waste contains large pieces of organic matter, so in order to deal with this food waste more effectively and thoroughly, the food waste should be shredded.

Features:

1. By double-shaft shredder, it can crush coarse materials (≥30mm) such as glass bottles, plates, dishes, shells, bones and other hard materials, as well as plastic, cloth, paper boxes and other light and flexible debris into small pieces effectively.
2. The food waste shredder blade is made of imported high-quality alloy steel, both high hardness and high toughness, with strong wear resistance and impact resistance, without frequent replacement.
3. The surface of the frame is treated with electrostatic powder spraying, and the hopper is made of 304 stainless steel, which has strong corrosion resistance.
4. Domestic famous brand power source, strong driving force, system processing capacity 5~20t/h.

Food waste press and dewatering machine

Features:

1. The part in contact with materials is made of 304 stainless steel, with strong anti-corrosion ability, and can be easily disassembled for maintenance after a long time use.
2. The spindle is dynamically balanced after all the assembly is completed, the whole machine is controlled by frequency conversion, the spindle speed is adjustable, and different speeds can be selected for different materials.
3. Adapt to various domestic kitchen waste (catering, food waste, etc.), can achieve a more ideal treatment effect.
4. The bearings adopt SKF brand, in order to ensure the service life of the bearings and stable operation, the bearing seat adopts an automatic lubrication system.
5. Domestic famous brand power source, strong driving force, system processing capacity 5~20t/h.

Food waste crushing and dewatering machine

For the situation that the food waste disposal machine site is relatively limited, we specially developed the crushing and dewatering integrated machine, the whole machine not only covers a small area, easy to layout, and can reduce the crusher and dewatering.

At the same time, the machine adopts sealed design, which can effectively reduce the problem of odor spillage at the treatment site.

Features:

1. The part in contact with the material is made of 304 stainless steel, which has strong anti-corrosion ability and can be easily disassembled for maintenance after long time of use.
2. One-piece design can greatly save equipment space.
3. For materials with particularly high water content, it can effectively solve the problem of difficult material conveying.
4. The bearing adopts the SKF brand, in order to ensure the service life of the bearing and stable operation, the bearing seat adopts an automatic lubrication system.
