After months of noise complaints from residents in multiple Nashville neighborhoods, the Buzzi Unicern cement plant in Germantown has agreed to upgrade its equipment in an effort to reduce the excessive noise coming from the facility. The plant, which has served Nashville for decades, will be replacing some of its existing compressors with new, more efficient units, though the company notes that noise reduction is not the primary driver of this investment.

Why it matters

The noise from the Buzzi Unicern cement plant has been an ongoing issue for residents in several Nashville neighborhoods, including Germantown, Salemtown, Cleveland Park, Highland Heights, and McFerrin Park, who have complained about a persistent hum that sounds like a perpetual lawn mower. This equipment upgrade represents an attempt by the company to address these community concerns.

The details

Metro Councilmember Sean Parker has been in ongoing dialogue with Buzzi Unicern about the noise issue, and the company has agreed to replace some of its existing loading equipment. While the primary driver for the upgrades is to enhance efficiency and reliability, the company believes the new, state-of-the-art compressors may provide improved noise mitigation, though they cannot guarantee specific reductions. There is no set timeline for when the equipment replacement will be completed, but the company hopes to have it done by the end of the year.

  • Residents have been complaining about the noise from the Buzzi Unicern plant for months.
  • The company plans to replace the equipment by the end of 2026.
