In aluminium recycling, selecting the scrap with the lowest purchase price does not necessarily mean choosing the most economical raw material. When assessing different scrap grades, the cost per tonne represents only one part of the overall economic equation.
To achieve the same annual production target, the volume of raw material required can vary significantly depending on metal content and recovery yield. Lower-grade or highly contaminated scrap requires more intensive processing, increased energy consumption and more complex residue management.
The profitability of a recycling plant depends on achieving the right balance between several technical and economic factors:
- 1. Purchasing Equation
The analysis should not focus solely on the purchase price per tonne. Metal recovery yield and the annual volume required to meet production targets are equally important variables.
- 2. Material Preparation
The efficiency of sorting, pre-treatment and decoating operations for post-consumer scrap has a direct impact on process performance and operating costs.
- 3. Melting Technology
Selecting the most suitable furnace technology is essential to optimise aluminium recovery:
→ Reverberatory Furnaces: Maximum efficiency for clean and properly prepared material.
→ Rotary Furnaces: Greater versatility and operational flexibility for processing complex or highly contaminated scrap streams.
- 4. Operating Costs
Energy consumption, dross and residue management, and the final value of the recovered aluminium all have a direct impact on overall plant profitability.
Looking Beyond the Price per Tonne
The key question is not which scrap grade offers the lowest purchase price, but which combination of raw material quality and processing technology delivers the lowest total production cost and the highest margin per tonne of recovered aluminium.
The most competitive recycling operations are those capable of optimising the entire system: charge mix, metal recovery yield, melting technology and final product value.
At Insertec, we work alongside aluminium recyclers to design the optimal technical solution for the specific requirements of each plant. From scrap preparation and decoating systems to the selection of the most efficient melting technology, we develop solutions focused on maximising operational profitability.
Our melting technology goes far beyond a standalone piece of equipment. It forms part of a comprehensive strategy designed to transform complex scrap streams into high-value recovered aluminium.
