Project Overview
-
Project Name: Gansu Municipal Solid Waste (MSW) Resource Recovery & WtE Project
-
Location: Gansu Province, China
-
Date: March 23, 2026
-
Material Handled: Mixed Municipal Solid Waste (MSW)
-
Process Goal: Automated sorting and high-density baling of high-calorific waste for delivery to Waste-to-Energy power plants
From Mixed Debris to Pure Energy
In Gansu, the local municipal solid waste (MSW) presented a significant challenge due to its diverse and high-moisture composition. To make Waste-to-Energy (WtE) commercially viable, the power plant required a fuel source with a consistent calorific value and free of non-combustibles such as glass, stones, and metals.
Our Solution: Integrated MBT (Mechanical Biological Treatment) Sorting Line
Guoxin Group implemented a high-efficiency sorting system designed to bridge the gap between urban waste collection and energy production.
1. Liberation & Pre-sorting
The raw MSW is fed into a Heavy-duty Plate Feeder, followed by an automated Bag Opener to ensure all waste is liberated for downstream mechanical separation.
2. Size & Material Separation
-
Trommel Screens: Used to remove organic “undersize” material and fines, which are diverted for composting or stabilized landfilling.
-
Air Density Separators: These systems cleanly isolate high-calorific light fractions (plastics, paper, textiles) from heavy inert materials like aggregates and glass.
-
Magnetic Separators: High-gradient magnets extract ferrous metals, protecting downstream shredders and creating an additional revenue stream.
3. RDF Preparation & Baling
The sorted combustible fraction is processed through high-torque RDF Shredders to achieve the optimal particle size. The final material is then compressed using heavy-duty Baling Systems for efficient transport to the nearby WtE power plant.
Project Impact & ROI
-
Waste-to-Energy Optimization: By providing a standardized, high-purity fuel, the system ensures stable boiler operation and maximizes electricity generation.
-
Landfill Diversion: Significantly reduced the volume of waste sent to local landfills, supporting China’s “Dual Carbon” and sustainability goals.
-
Automated Efficiency: The centralized PLC control system minimizes labor requirements while maintaining high throughput and recovery rates.
Technical Highlights
-
Turnkey EPC Service: Guoxin provided the full design, manufacturing, and onsite commissioning for the Gansu site.
-
Commercial Sustainability: The project demonstrates how intelligent sorting turns environmental liabilities into high-value industrial assets.
