Tech‑Driven Smell Control at U.S. Landfills
Current overview (not historical)
In California’s Milpitas, local officials have mandated that landfill operators employ drones and monitoring equipment to track chemical emissions and automatically capture odor‑producing gases. Meanwhile, Des Moines, Iowa, is investing $240,000 annually in electronic‑nose technology that uses weather data and chemical concentration readings to pinpoint the source of landfill odors. These initiatives illustrate a growing trend of using advanced sensing and automation to mitigate the environmental and public‑health impacts of landfill emissions.

Report first recorded Oct 16, 07:35
Residents in Milpitas, a Silicon Valley city, have long endured odors from industrial sites, including a 342-acre landfill. Local authorities have ordered the landfill operators to use drones and monitors to track odor-causing chemicals and to automate landfill gas collection. An odor consultant Micheal Bull said people are increasingly concerned about neighborhood stinks due to urban sprawl bringing communities closer to odorous processes. Experts note that the best odor-fixing technologies can remove 90% or more of target compounds.
