August 2014 – A California-based concrete producer, Graniterock, returned to concrete recycling after abandoning it in the late 1990s. In an article in the August 2014 issue, Reclaiming Revisited, Concrete Products editor Don Marsh writes:
Graniterock is among ready mixed producers that installed reclaimers for aggregate and slurry recycling, but abandoned them due to equipment limitations and cost-benefit factors. Improved reclaiming and water management equipment, coupled with the scarcity of land from San Francisco to Silicon Valley, have compelled the producer’s Concrete Division to manage its own process-waste stream.

Fortunately, concrete reclaiming equipment has come a long way in the last 15-20 years. A new BIBKO 4000 installation by DHE Inc. allows Graniterock to eliminate waste hauling from production to recycling areas and conserve water, always a big deal in California but especially so with the recent drought.
