Fresh Kills on Staten Island was, for decades, the largest municipal landfill on the planet — a mound of refuse so vast it was reportedly visible from low Earth orbit. This video traces the engineering story of how that 2,200-acre mountain of trash is being converted into one of the largest urban parks in the United States, more than twice the size of Central Park.

The interesting engineering isn't the trash — it's what happens after closure. Capping a landfill of this scale requires a multi-layer geomembrane and soil system to isolate waste from rainwater, a gas-collection network to capture methane produced by decomposing organics (which is then piped to heat roughly 22,000 homes), and a leachate management system that will run for generations. The video should touch on differential settlement — the mound is still slowly compacting, which constrains what can be built on top — and on the drainage grading required to keep infiltration out of the waste mass.

The channel is tiny (9 subscribers) and the title leans slightly sensational, but the underlying subject is legitimate civil and environmental engineering: post-closure landfill design, methane recovery, and long-horizon land reclamation.
