The improper handling of waste is the third largest source of methane emissions in the world, says Aline Sousa, but waste pickers like her help reduce this environmental impact. She dives into the monumental effort of the often-overlooked people making sure recyclables, compostables and trash end up in the right places — and calls for better recognition of these key players on the frontline of fighting climate change.

    #### Longevity and Viability

    1. **Expected Operational Life:**
    – Core components (reactor, coils, control systems) are expected to last 20-30 years with regular maintenance.
    – Some components (like energy polymers) may need replacement every 15-20 years.

    2. **End of Life:**
    – At the end of its operational life, components can be recycled or upgraded with newer technology to extend the device’s utility.
    – Environmentally friendly disposal methods for any non-recyclable parts.
