Kitchen waste, food waste (leftover food, vegetable leaves, meat bones, fish bones, waste edible oils and fats)
Municipal Solid Waste / Organic Waste
Organic Waste
Food waste refers to food residues, food processing scraps, expired food products, and waste edible oils and fats generated by food service establishments during food production and business activities.
SOLUTION
What We Can Do: Our Advantages
The equipment supports fully automated operation with fault alarm functionality, designed to reduce reliance on manual attendance and enhance management efficiency. The full-chain services it provides — including solution design, installation and commissioning, and O&M training — constitute a complete commercial solution.
INPUT & OUTPUT
Input and Output
Oils, energy (e.g., biogas), solid organic fertilizer and soil conditioners, animal and aquaculture feed
CORE TECHNOLOGY
Core Technology
01
Anaerobic Fermentation
Under oxygen-free conditions, microorganisms decompose organic matter into biogas (primarily methane) and digestate. This is the current mainstream technology with high energy recovery rates. Biogas can be used for power generation or upgraded to natural gas, and digestate can be processed into organic fertilizer.
02
Aerobic Composting
Under aerobic conditions, microbial fermentation generates heat and converts waste into organic fertilizer or soil conditioners.
ADVANTAGES
Advantages
Full-Quantity Resource Recovery and High-Value Utilization
Moving beyond traditional single-mode treatment (e.g., composting only or incineration only), integrated processes (such as "bidirectional enhanced multi-source co-processing" technology) extract and separately utilize all components — oils, organic matter, and solid residues — from the waste stream.
Technology Integration and Intelligence
Utilizes NIR spectroscopy identification, AI vision, and robotic arms to automatically sort out impurities such as plastics and metals, solving the challenge of complex composition and high impurity content in kitchen waste.
Energy Self-Sufficiency and Carbon Reduction
Biogas from anaerobic fermentation generates electricity, and waste heat recovery systems provide self-heating, creating a "negative energy consumption" or "energy self-sustaining" operating model.
PROJECT CASES
Project Cases
Chongqing Food Waste Processing Project
- Location
- Chongqing
- Daily Processing Capacity
- 500 t/d
The Chongqing Luoqi waste processing project was commissioned in 2021 with a designed processing capacity of 500 t/d, primarily handling household kitchen waste from Chongqing's main urban districts. The collected household kitchen waste in Chongqing has a relatively high impurity content. The project adopts a pre-sorting technology of "crushing + two-stage screening + negative-pressure air separation + optical sorting + extrusion + wet anaerobic digestion + dry anaerobic digestion + resource recovery (plastics) + incineration," which effectively removes impurities. The resource recovery section employs optical sorting technology to recover plastics from kitchen waste. After impurity removal, the organic matter enters the dry anaerobic digestion system. Under anaerobic conditions, organic matter is converted into carbon dioxide and methane gas through the action of natural or inoculated microorganisms. The collected methane gas can be purified and supplied to the plant's boilers for heat generation.
Chongqing Food Waste Processing Project 02
- Location
- Chongqing
- Daily Processing Capacity
- 400 t/d
The Chongqing Xiajiaba processing project was commissioned in 2020 with a designed processing capacity of 400 t/d. Its function covers waste processing and transfer operations for Chongqing's central districts. The collected household kitchen waste in Chongqing has a relatively high impurity content. The project adopts a pre-sorting technology of "crushing + two-stage screening + negative-pressure air separation + optical sorting + off-site disposal + resource recovery (plastics)," which effectively removes impurities. The resource recovery section employs optical sorting technology to recover plastics from kitchen waste. After impurity removal, the organic matter and screened combustible materials are transported by transfer vehicles to downstream dry anaerobic digestion tanks and incineration plants.
Hefei Food Waste Processing Project
- Location
- Anhui
- Daily Processing Capacity
- 400 t/d
The Hefei Xiaomiao food waste processing project began construction in 2020 and has now entered the trial operation phase. The project has a designed processing capacity of 400 t/d, with plant facilities including restaurant waste pre-processing, kitchen waste pre-processing, dry anaerobic digestion, wet anaerobic digestion, wastewater treatment, biogas upgrading, and biogas power generation systems. The kitchen waste pre-processing technology adopts "bag breaking + two-stage screening + magnetic separation + extrusion." After impurity removal, the organic matter enters the dry anaerobic digestion system, while the liquid fraction, after sand and impurity removal, enters the wet anaerobic digestion system. Biogas produced by the anaerobic systems is used in the boiler system for heat generation or for grid-connected power generation. Dewatered digestate from the anaerobic systems, together with impurities screened out from the sorting workshop, is consolidated and transported off-site for incineration.
