  • Concrete recycling systems from Liebherr

    A far better solution is to use a Liebherr concrete recycling plant to separate the constituents before they are fully hardened. Since everything can be re-used, both material and process water are saved when new concrete is produced. The residual water from recycling can easily be returned to the production process. The gantry used to wash out truck mixers can also be supplied with water ...
