Municipal Solid Waste / Organic Waste
Organic Waste
Food waste refers to food residues, food processing scraps, expired food, and waste edible oils generated by food waste producing units during food production and business activities.
SOLUTION
What Can We Do? Our Advantages
The equipment supports fully automatic operation with fault alarm functions, designed to reduce reliance on manual monitoring and improve management efficiency. The full-chain services provided, including solution design, installation and commissioning, and operation and maintenance training, constitute a complete commercial solution.
INPUT & OUTPUT
Input and Output
Oils, energy (such as biogas), solid organic fertilizer and soil conditioner, animal/aquaculture feed
CORE TECHNOLOGY
Core Technology
01
Anaerobic Fermentation
In an oxygen-free environment, 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 purified into natural gas, and digestate can be made into organic fertilizer.
02
Aerobic Composting
Under aerobic conditions, microorganisms ferment and generate heat, converting waste into organic fertilizer or soil conditioner.
ADVANTAGES
Advantages
Full Resource Recovery and High-Value Utilization
Moving beyond traditional single-method treatment (such as composting only or incineration only), adopting integrated processes (such as "dual-enhanced multi-source synergistic" technology) to separately extract and utilize all components of waste including oils, organic matter, and solid residues.
Technology Integration and Intelligence
Using near-infrared spectrum 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
Generating electricity through anaerobic fermentation-produced biogas, or using waste heat recovery systems for self-heating, forming a "negative energy consumption" or "energy self-sustaining" model.
PROJECT CASES
Project Cases
Chongqing Kitchen Waste Disposal Project
- Location
- Chongqing
- Daily Processing Capacity
- 500 t/d
The Chongqing Luoqi waste treatment project was put into operation in 2021, with a designed processing capacity of 500 t/d, primarily handling household kitchen waste from Chongqing's main urban area. The collected household kitchen waste in Chongqing has high impurity content. Using a pre-sorting technology of "crushing + two-stage screening + negative pressure air classification + optoelectronic sorting + extrusion + wet anaerobic digestion + dry anaerobic digestion + resource recovery (plastics) + incineration," impurities can be effectively removed, with the resource recovery section using optoelectronic 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 natural or inoculated microorganisms; the collected methane gas can be purified and supplied to the plant boiler for heat production.
Chongqing Kitchen Waste Disposal Project 02
- Location
- Chongqing
- Daily Processing Capacity
- 400 t/d
The Chongqing Xiajiaba treatment project was put into operation in 2020, with a designed processing capacity of 400 t/d, serving waste treatment and transfer operations for Chongqing's central area. The collected household kitchen waste in Chongqing has high impurity content. Using a pre-sorting technology of "crushing + two-stage screening + negative pressure air classification + optoelectronic sorting + offsite disposal + resource recovery (plastics)," impurities can be effectively removed, with the resource recovery section using optoelectronic sorting technology to recover plastics from kitchen waste. After impurity removal, the organic matter and screened combustibles are transported by transfer vehicles to downstream dry anaerobic digesters and incineration plants.
Hefei Kitchen Waste Treatment Project
- Location
- Anhui
- Daily Processing Capacity
- 400 t/d
The Hefei Xiaomiao kitchen waste treatment project began construction in 2020 and has now entered trial operation. The project has a designed processing capacity of 400 t/d, with plant construction including food waste pretreatment, kitchen waste pretreatment, dry anaerobic digestion, wet anaerobic digestion, wastewater treatment, biogas purification, and biogas power generation systems. The kitchen waste pretreatment process uses "bag breaking + two-stage screening + magnetic separation + extrusion" to remove impurities, after which the organic matter enters the dry anaerobic digestion system, and the liquid phase enters the wet anaerobic digestion system after sand and impurity removal. The biogas produced by the anaerobic system enters the boiler system for heat production or biogas power generation for grid connection. The digestate produced by the anaerobic system, after dewatering, is combined with impurities screened from the sorting workshop and transported offsite for incineration treatment.
