5.3B Managing Pollution and Waste

Pollution and Waste as a Global Challenge

This is an HL-only sub-topic: how digital systems detect pollution, design waste out, and generate new waste of their own.
It is a challenge because the harm travels and lingers: plastics ride rivers and oceans far from source, some pollutants persist for centuries, and the burden lands on communities that did not produce it.
Framing concepts: systems (waste moves through linked natural and economic systems), values and ethics (fairness to distant and future communities), and space (waste is shipped from richer to poorer countries).

Seeing Pollution

Networks of low-cost sensors measure air and water quality street by street, and satellites track ocean plastic, illegal dumping, and smog across regions.
Sensors and big data turn a diffuse, invisible problem into a live map for communities, regulators, and scientists (concepts: systems, space).
Result: communities gain clearer, more local, more trusted knowledge of what they breathe and drink, letting authorities target enforcement and warn the public.
1. Contested: cheap sensors vary in accuracy, and data changes nothing if no one acts.

Closing the Loop

In a circular economy, materials are tracked, repaired, reused, and recycled rather than thrown away, and digital tools make that tracking possible at scale.
