Case study: Recycling ACSR cables for profit

ACSR (Aluminum Conductor Steel Reinforced) cables are commonly used in electrical applications due to their high mechanical strength and good conductivity. They consist of aluminium wires twisted around a galvanized steel core. Recycling this type of cable can be profitable but requires careful consideration of the process, equipment and market.

The recycling process

Recycling of ACSR cables (aluminum steel reinforced conductor cable) involves several essential steps to separate and recover the component materials:

• Collection and sorting: ACSR cables are collected from various sources such as electricity companies or demolition projects for efficient recycling of raw materials.
• Cutting cables: Specialized tools, such as ACSR industrial cable cutting shears, are used to cut cables into smaller pieces, facilitating the process later.
• Shrinking: The cables are inserted into a shredder specialized for shredding. This process physically separates aluminum from steel by differences in density and strength.
• Separation of materials: Magnetic separators extracting steel wires from the mixture and sgravity separators for aluminum which is lighter and to be separated from other impurities.
• Refining materialsAluminum and steel are cleaned and prepared for sale to factories that reuse them.
• Auxiliary systems: Conveyor belts that ensure efficient material handling between process steps and dust control systems that reduce environmental impact during shredding and separation.

Profitability analysis

The profitability of ACSR cable recycling depends on several factors:

Value of recovered materials

• Separated aluminum has a high market value, between 2.500 and 3.500 USD/tonne, depending on purity and demand.
• Oțelul has a lower value, between 200 and 500 USD/tonne, but contributes to additional revenue.

Operational costs

• Equipment (e.g. shredder, separators) and consumables costs can be significant.
• The labor needed to operate and maintain the machines is another major cost.

High volumes = high profits

For large-scale operations, aluminum and steel separation becomes more cost-effective due to economies of scale. For example:

• Selling unprocessed cables can fetch between $1,500 and $2,200/tonne.
• Separation allows the aluminum to be sold at a higher price, maximizing profits.

Market demand

• Aluminum is in stable demand due to its widespread use in industries such as construction and transportation.
• Steel is less valuable but has a steady flow on the scrap market.

Conclusion

Separating aluminum and steel from ACSR cables can be profitable, especially in large-scale operations. Although initial equipment and labor costs can be high, the revenue from selling the separated materials can significantly exceed them. To maximize profit:

• It is essential to invest in efficient machinery that reduces material losses.
• Constant monitoring of the metals market helps choose the optimal time to sell.

This business can become sustainable in the long term by combining high volumes with efficient strategies for processing and selling recycled materials.
