Sources of waste heat from the plant include heat from the stack gas and heat generated during ageing that raises the temperature of bottom ash to 70–80 °C. It would be a challenging job for an industrial engineer to harvest this waste heat, but if realized, it can make the process more economic and sustainable.

Your best solution for excess concrete materials at any concrete plant starts with simply addressing the issue, and developing a plan. Without a plan, your pile of "concrete waste" will likely continue to grow. With a well thought-out plan, you'll find operational, compliance, and financial benefits you likely aren't receiving now.

The heterogeneous characteristics of the huge quantity of wastes generated lead to complexity in recycling and utilisation.
