Comparison of Crushed Circuit Boards and Separated Copper, Aluminum, and Plastics
What is WEEE Recycling?
WEEE (Waste Electrical and Electronic Equipment), commonly known as E-waste, comprises a complex mix of materials—some hazardous, others extremely valuable. A professional E-waste Recycling Plant is an integrated facility designed to dismantle, shred, and separate these components (such as PCBs, cables, and casings) into pure secondary raw materials like copper, aluminum, gold, and high-grade plastics.
At Guoxin Machinery, we provide modular WEEE recycling systems that balance automated mechanical separation with manual dismantling stations, ensuring maximum value extraction while strictly adhering to international environmental safety standards (such as R2 and e-Stewards).
Process Overview: How Does a WEEE Recycling Plant Work?
Our engineering team designs the flow based on the “Recovery First” principle, ensuring that hazardous components are safely removed before high-speed shredding.
-
Primary Dismantling & Hazardous Removal: Manual or semi-auto removal of batteries, toner cartridges, and large capacitors to prevent contamination and fire risks.
-
Multi-Stage Shredding: Utilizing low-speed, high-torque twin-shaft shredders to reduce bulky electronics into 20-50mm fragments.
-
Density & Air Separation: Isolating heavy fractions (metals) from light fractions (plastics and dust) using precision air classifiers.
-
Magnetic & Eddy Current Separation: High-intensity magnets extract ferrous metals, while eddy current separators recover aluminum and copper.
-
PCB Fine Processing: Circuit boards (PCBs) are further crushed and separated using high-voltage electrostatic separators to recover precious metals with up to 99% purity.
-
Emission Control: The entire line is equipped with pulse dust collectors and activated carbon filters to ensure clean air discharge.

Key Revenue Streams: What Materials Can You Recover?
An E-waste plant is a high-yield investment. The purity of the recovered commodities drives the revenue:
-
Precious Metals (PCBs): Gold, Silver, and Palladium recovery through specialized PCB processing modules.
-
Non-Ferrous Metals: High-purity Copper (from cables/motors) and Aluminum (from casings/heat sinks).
-
Ferrous Metals: Clean steel and iron scrap for foundries.
-
Technical Plastics: Sorted ABS, PC, and PS for high-end plastic recycling markets.

FAQ for E-waste Investors
Q1: Can your plant process CRT monitors and Lithium batteries?
A: We provide specialized modules for CRT glass cleaning and safe Lithium battery discharge. However, these are handled as pre-treatment steps to ensure the safety of the main shredding line.
Q2: What is the ROI of an E-waste recycling facility?
A: Due to the high value of precious metals in PCBs, most WEEE recycling projects achieve a return on investment within 1.5 to 2.5 years, depending on feedstock volume and local commodity prices.
Q3: How do you control the dust and toxic fumes during shredding?
A: Every Guoxin E-waste line is fully enclosed with a centralized dust extraction system and a chemical scrubber to neutralize acidic gases and capture lead/mercury dust.
