Materials, Waste and Pollution

What we manufacture does not disappear once it leaves home in a bag or down a drain.

The bag leaves the house; the matter carries on

When something gets thrown into the bin, into a recycling container, or down the drain, it disappears from the sight of whoever threw it away, but the matter it is made of does not disappear from the world: it keeps existing somewhere, transforming, accumulating, or circulating again, depending on what decisions get made after that first gesture. Plastics, clothing, electronic devices, food and hazardous chemical products all share the same underlying structure: each one carries behind it a history of raw-material extraction, manufacturing, transport and use that consumed real energy and resources, and that history is not canceled simply because the object has stopped being useful to whoever had it.

Following the matter after the bin, the drawer or the drain

This block walks through seven different stories about materials and waste, each with its own physics and its own management chain: plastics and their real fates after the container, microplastics that shed without anyone seeing them, clothing and textiles that start in a cotton field or an oil well, electronic waste that still contains valuable metals, hazardous household waste that must never be mixed with running water, and food waste, which also throws away all the energy and water invested in producing it. The same underlying hierarchy appears in every one of them: reducing unnecessary use matters more than reusing, reusing matters more than recycling, and recycling — always preferable to simply throwing away — never recovers one hundred percent of what was invested in manufacturing the original object.
