Exploring metal recovery opportunities in Wash Plant output

Looking Beyond the Aggregates

Wash plants play an important role in processing construction and demolition waste, helping to remove unwanted materials and produce clean, quality aggregates for reuse and resale.

But producing quality aggregates is only part of the picture. Once material has passed through the washing process, there may still be valuable metals within the output that could be recovered through further separation.

With more operators looking at how they can maximise the value of the material they handle, metal recovery is becoming an increasingly interesting opportunity for the wash plant sector.

A recent material trial with a UK wash plant operator explored exactly this: what metals remained in the processed material, and was there potential to recover more value from it?

What Did the Trial Show?

The trial involved assessing a sample of wash plant output to identify the ferrous and non-ferrous metals remaining after the main processing stage.

Testing confirmed that valuable metals were still present in the material, highlighting an opportunity to investigate whether additional separation could improve overall recovery.

Although the sample was relatively small, it provided a useful insight into the material and helped establish whether further investigation was worthwhile.

Of course, every wash plant is different. The potential for metal recovery depends on factors such as particle size, material composition, contamination levels and the concentration of recoverable metals. Understanding these characteristics is essential when deciding which separation technology may be suitable.

Why Are Wash Plants Looking at Metal Recovery?

For wash plant operators, the opportunity is to look beyond the primary objective of producing clean aggregates and consider what else can be recovered from the material passing through the site.

Depending on the composition and volume of the output, recovering ferrous and non-ferrous metals could create an additional revenue stream from material that is already being processed.

It is also an opportunity to make better use of existing resources, reducing the amount of potentially valuable material leaving the plant without further recovery.

However, the commercial case needs to stack up. Metal content, recovery rates, processing capacity, additional equipment requirements and operating costs all need to be considered before deciding whether a separation system is a worthwhile investment.

Start With the Material

The best place to start is with the material itself.

Material testing allows operators to understand what remains in their output streams, identify potential recovery opportunities and assess whether further separation is technically and commercially viable before committing to additional equipment.

From there, the appropriate solution will depend on the material characteristics and the requirements of the existing plant.

Producing quality aggregates remains the priority, but understanding what else can be recovered could unlock additional value from the same material stream.
