  • Fly Ash for California’s Olivenhain Dam case study

    The Olivenhain Dam will be the first roller compacted concrete (RCC) gravity dam in California and the tallest in North America. At 308 feet tall and 2,552 feet long, the dam used almost 1.5 million cubic yards of RCC and over 152,000 tons of fly ash. As the centerpiece of the San Diego County Water Authority (SDCWA) Emergency Storage Project, the dam is designed to survive a major earthquake and ...

  • Like a phoenix from the ashes

    Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can't easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for disposal and reclaiming, such as the KVA Linthgebiet in Niederurnen in the Swiss canton of Glarus. Due to the strict environmental specifications ...
