Rio Nuevo Landfill, Tucson, Arizona – A Hybrid Approach to Landfill Management

The Rio Nuevo Landfill in Tucson, Arizona, presented a unique challenge due to its hot, arid climate and a history of waste management issues. TGD Environmental employed a hybrid aerobic-anaerobic bioreactor approach, utilizing the ALBS system to enhance landfill performance.

• Results:
  • Enhanced Waste Degradation: The ALBS system accelerated the breakdown of waste, reducing the landfill’s operational lifespan and associated environmental risks.
  • Temperature Control: The hybrid approach allowed for better temperature management, preventing overheating and ensuring consistent aerobic conditions.
  • Methane Emissions Control: Methane production was reduced by over 65%, contributing to Tucson’s climate action goals.
  • Land Reclamation: The faster stabilization allowed for early-stage planning of land reclamation, opening up possibilities for future land use.
