To address these multifaceted challenges, Oizom deployed two units of Polludrone Custom at the Gelephu International Airport construction site in April 2025

Key highlights of the solution:

• Comprehensive Environmental Monitoring: Polludorne ensures high accuracy in measuring CO, CO₂, SO₂, NO, NO₂, and O₃ along with PM (PM1, PM2.5, PM10, PM100), and meteorological parameters like, noise, UV, light intensity, wind direction and speed, and Temperature, Humidity & Pressure (THP) for safety and compliance during unpredictable construction emissions.
• Remote Monitoring with Minimal Maintenance: With remote data access and self-diagnostics, the system requires minimal maintenance, perfect for Gelephu’s remote site with limited on-ground technical manpower.
• Envizom for Centralized Decision-Making: Envizom enables centralized monitoring with real-time dashboards, alerts, and historical analytics, supporting proactive decisions and transparent environmental reporting.
• Weatherproof and Rugged Design: IP65-rated enclosures and climate-resilient sensors ensure uninterrupted performance in Bhutan’s varying weather conditions, from high humidity to monsoon rains.
• On-Ground Support: Local partner Ecolab provided seamless installation, calibration, and ongoing support, ensuring high system uptime and localized technical expertise.
• Real-Time Alerts for Proactive Response: Threshold-based alerts for dust, noise, gas, and UV help project teams take quick actions, reducing environmental risk and ensuring worker safety.

This solution was implemented with local expertise from Ecolab Analytical and Technical Centre Bhutan, ensuring seamless integration, calibration, and operational continuity.

The deployment of Oizom’s Polludrone Custom at Gelephu Airport led to tangible and multi-layered benefits:

• Proactive Pollution Management: Continuous tracking of particulate and gas pollutants allowed for timely mitigation and ensured compliance with Bhutan’s environmental norms.
• Data-Driven Construction Planning: Real-time environmental insights via Envizom enabled project teams to schedule work based on favorable weather and pollutant trends, minimizing ecological disruption.
• Sustainability Reporting: Regular reports with accurate and continuous environmental data, streamlined compliance documentation, and sustainability disclosures, supporting the long-term environmental goal of the city.
• Future-Ready Infrastructure: Installing air quality monitors established the foundation for smart city integration, supporting Bhutan’s larger vision for intelligent urban ecosystems.
• Early Warning Alerts: Threshold-based notifications on the Envizom platform empower on-ground teams to swiftly respond to spikes in pollutants, UV radiation, or noise.

The successful deployment of Oizom’s continuous air quality monitoring solution at Gelephu International Airport showcases the critical role of environmental intelligence in modern infrastructure development.

The installation is more than a monitoring initiative, it is a foundation for Bhutan’s long-term sustainable development vision:

• Transparent Sustainability Reporting: Reliable, exportable data from Envizom supports compliance reporting and stakeholder communication.
• Smart Infrastructure Readiness: The system aligns with the larger smart city framework, enabling long-term scalability for future urban development.
• Environmental Consciousness: Real-time environmental awareness has fostered a culture of mindfulness and ecological sensitivity among workers and stakeholders.

The collaboration between Gelephu International Airport, Ecolab Analytical and Technical Centre Bhutan, and Oizom exemplifies how real-time environmental monitoring can drive sustainable infrastructure development. By integrating Polludrone Custom into the early phases of airport construction, stakeholders ensured that sustainability was embedded, not added later.

As Bhutan moves forward with its ambitious Mindfulness City vision, Gelephu now stands as a benchmark for data-driven, future-ready development where environmental stewardship and progress go hand in hand.
