E-Waste Goldmine: The Complete Guide to Profitable Circuit Board Shredding & Metal Recovery

With over 50 million tons of e-waste generated globally each year, do you realize this is not just an environmental challenge, but a reservoir of metal resources worth more than $60 billion? In the field of 3C waste recycling, maximizing value extraction from circuit boards, casings, and cables has become the key differentiator between ordinary recyclers and industry leaders.

 The Hidden Value in E-Waste: More Than Just a Mix of Plastic and Metal

E-waste contains astonishing amounts of metal:

- Circuit Boards: Contain copper (10-20%), gold (0.05-0.1%), silver (0.2-0.5%), and precious metals like palladium.

- Cables: Copper content as high as 30-40%, with some premium cables reaching 60%.

- Casings: A perfect blend of high-value engineering plastics like ABS, PC, and aluminum-magnesium alloys.

However, traditional processing methods—such as incineration, chemical leaching, or crude mechanical dismantling—not only yield low recovery rates (typically only 40-60%) but also cause severe secondary pollution and resource waste.

 Precision Shredding Technology: A Revolutionary Breakthrough in E-Waste Recycling

True "e-waste profiting" begins at the pre-processing stage, with precision shredding being the core technology. Traditional hammer mills or single-shaft shredders face numerous challenges when processing e-waste:

- Incomplete separation of metals and non-metals

- Over-shredding leading to metal oxidation and loss

- Difficulty in dust control, posing safety hazards

The LESINTOR Solution: Targeted Precision Shredding Systems

1. Dedicated Circuit Board Shredder: Utilizes multi-stage crushing + air separation design

   - Primary coarse crushing: Reduces whole circuit boards to 30-50mm pieces

   - Secondary fine crushing: Special blade design shreds material to 5-10mm

   - Eddy current separation: Highly efficient separation of non-ferrous metals from plastics, achieving copper recovery rates over 95%

2. Integrated Cable Stripping and Shredding System

   - Strips first, then shreds: Recovers insulating sheath (PE/PVC) and internal copper core intact

   - Produces copper granules with purity up to 99%, suitable as direct raw material for refining

3. Dedicated Plastic Casing Shredder

   - Low-speed, high-torque design prevents plastic overheating and degradation

   - Adjustable output size to meet different downstream processing needs

   - Metal detectors automatically remove residual screws and other impurities

 Key Technologies for Improving Metal Recovery Rates: The Complete Process from Shredding to Separation

Successful e-waste recycling companies follow an optimized process:

Step 1: Intelligent Sorting and Pre-Dismantling

Utilize LESINTOR pre-dismantling workstations to sort e-waste by type and metal content, improving subsequent processing efficiency.

Step 2: Targeted Shredding Solutions

- High-value circuit boards → Closed, explosion-proof shredding system

- Mixed cables → Wet shredding to reduce dust risk

- Plastic casings → Low-speed shearing to prevent thermal damage

Step 3: Efficient Physical Separation Technologies

- Electrostatic separation: Processes finely shredded material, separating metals from non-metals

- Gravity separation: Separates mixed materials based on different densities

- Magnetic separation: Removes ferrous materials, protecting downstream equipment

Step 4: Dust and Exhaust Management

LESINTOR systems are equipped with high-efficiency filters and activated carbon adsorption units, ensuring compliance with European and American environmental standards.
