Back to agenda HERCAL DIGGERS – [RE]Building the future: Concrete with recycled aggregate Tue 21 Sep | 13:00 - 13:15 For Hercal, demolition is not the end of the life of a structure, but the beginning of a new one. We are committed to selective demolition and to the real valorisation of waste, transforming it into recycled aggregates treated to make concrete. Our ambition is to reduce the need for landfills and rationalise the use of quarries.
