Case Study: KBH Crusher – From Reject Concrete to High-Value Asset
This article describes transforming concrete waste into high-quality recycled aggregate – with no screening, no additional labour costs (utilising existing plant infrastructure), and a consistent grading curve regardless of feed variation.
1 The Challenge
Hardscape manufacturing plants routinely generate significant volumes of reject material and off-cuts from splitting lines. This material is usually stockpiled on site, consuming valuable property space and incurring additional expenses for crushing and off-site transportation. While some revenue can be generated by selling this material as low-grade fill or bedding layer, far greater economic value is unlocked by re-integrating the material directly back into the concrete mix to replace the most expensive aggregate fractions. Furthermore, factory real estate can be utilised...
