Global regulations such as the Carbon Border Adjustment Mechanism (CBAM) and the EU Green Deal are forcing industrial manufacturers to drastically reduce carbon footprints. While many companies make progress in reducing direct emissions (Scope 1) and indirect emissions from purchased energy (Scope 2), the most challenging category remains Scope 3 Carbon Emissions, which covers the value chain and product lifecycle. Carbon emissions in industrial IoT networks directly drops when eliminating cabling infrastructure and lithium batteries.
Life Cycle Assessment (LCA): Cabling vs. Energy Harvesting
The materials used in typical wired sensor installations carry high embodied carbon emissions from their manufacturing phases. According to Life Cycle Assessment (LCA) database parameters:
- Shielded Copper Instrumentation Cable Footprint: Mining, processing, and shipping shielded copper instrumentation wires causes an average of 0.8 kg CO₂ per meter.
- Steel Cable Tray & Support Footprint: Heavy-duty hot-dip galvanized steel cable trays and supports add approximately 8.5 kg CO₂ per meter.
- Lithium Battery Production & Swap Footprint: Manufacturing, transporting, and disposing of industrial lithium battery cells used in wireless sensors creates an average of 2.5 kg CO₂ per swap cycle.
If a facility connects 200 sensors with an average cable run of 25 meters, the infrastructure setup alone generates approximately 46.5 tons of CO₂ emissions.
Environmental Value of Self-Powered IoT Sensors
Deploying ESCOM-es’s specialized WiT-es C (Self-Powered Pipe Temperature Sensor) and ViBT-es S (Self-Powered Vibration Sensor) batteryless sensors completely eliminates these carbon sources by converting ambient waste heat and mechanical vibrations into electricity.
The main sustainability benefits of self-powered IoT include:
- Zero Cabling Infrastructure: Eliminates kilometers of copper cables and tons of steel trays, reducing initial installation embodied carbon by over 90%.
- Zero Chemical Battery Waste: Uses high-durability supercapacitor storage cells to prevent hazardous lithium chemicals from reaching landfills or requiring recycling transportation.
- Circular Economy Alignment: Maintenance-free operations for a service life exceeding 10 years eliminates recurring logistics transport emissions from service vehicles.
