The Hidden Engineering of Landfills
Why Hacker News recommends it
HN commenters cite it as a clear, visual explainer on modern landfill engineering, often when discussing landfills, waste, or recycling, though one commenter calls such videos superficial.

What it is
Grady Hillhouse of Practical Engineering explains how modern engineered landfills are designed, including liners, leachate collection, gas management, daily cover, and capping. The video uses visualizations and models to show how these systems keep waste out of soil, air, and water.

Thanks for the share, crazy that 1-2mm polyethylene is all it takes to cap a landfill. Practical Engineering put out an excellent video on landfills a couple years back, well worth the watch for the visualizations alone. [this video]

This was pointed out to me a while ago, but it seems to hold true: Whether someone appreciates a modern engineered landfill is a useful Shibboleth for distinguishing real evidence-based environmentalism from narcissistic signaling "environmentalism." [this video]

admittedly, it does fall far short of being practical; if your preparation for building a railroad is watching [LINK] and your preparation for building a landfill is watching [this video] , your trains will derail and your garbage will leach into your groundwater but that's not really a difference between the two channels; real engineering manages to pack plenty of misstatements into videos that are equally superficial
