Your Trash Will Outlive You!

Описание: When you throw something away, it goes to a landfill — and most of it stays there far longer than you might think. This video breaks down the real decomposition timeline for the most common materials in your trash, from food scraps to aluminum cans to plastic bottles to glass.


Modern sanitary landfills are engineered facilities, not open dumps. But the same design features that make them safe — the sealed liners, the compacted layers, the limited moisture — also create a near-oxygen-free environment that dramatically slows decomposition. A banana peel that breaks down in weeks in a compost pile can take two years in a landfill.


Newspapers buried decades ago have been recovered still readable.
This video covers the full system: how waste reaches the landfill, what happens inside as it decomposes through four distinct phases, how landfill gas and leachate are managed, and what happens to a closed landfill over the decades that follow.


Material timelines covered: food scraps and organics (weeks to months, extended significantly in landfills), paper and cardboard (6 weeks to months), aluminum cans (80 to 100 years), plastic bottles (450 years or more), disposable diapers (250 to 500 years), and glass (up to 1 million years, or effectively never).
