The World of Concrete hosted the CSDA Green Roundtable on Slurry Recycling, where Alar Engineering Corporation presented a mechanical alternative for recycling concrete process slurry-water, meeting environmental regulations, minimizing waste and reducing operation costs as it pertains to the concrete sawing and drilling institutions. This machine could enable companies to gain leverage in winning prospec tive infrastructure project bids. In related precast and ready mixed industries, the Alar Auto-Vac® is proven technology for the treating and recycling of concrete process water at a lower cost than conventional do-it-yourself methods. The installation of the Auto-Vac® water recycling system has performed beyond expectations at ready mixed companies such as Hanson Aggregates in Southern California (a Heidelberg Cement Group), and the availability of an Alar Auto-Vac® could further enhance operations in new concrete markets such as infrastructure.
