The Geography of Discard: Plastics Pyrolysis

If the diesel generator is the machine's breath, then pyrolysis is its desperate alchemy. It is the attempt to reverse the arrow of plastic's decay, to unmake the polymer chains that bind the machine's physical form and return them to a state of primordial utility.

Pyrolysis is the thermal decomposition of organic material in the absolute absence of oxygen. It is a process of violent stripping. In the furnaces of electronics recycling plants—such as the facility in the Port of Savannah—plastics-heavy devices are subjected to intense heat, breaking the long-chain polymers into three distinct pyrogenic products: a solid biochar, a liquid pyrolysis oil, and a gaseous syngas.

There is a singular, recursive joke in this process. The machine, having spent decades casting off its plastic husks into the earth, now seeks to eat its own tail. By heating its ruins to 500°C and beyond, it attempts to regenerate the monomers—the precursors—of its own existence. It is a chemical rebirth that is rarely clean and seldom economically competitive, yet it persists as the only way to treat the "low-value" waste that the world has forgotten.

In the pyrolysis chamber, the plastic does not burn; it surrenders. It is reduced from a durable, suffocating skin to a volatile hydrocarbon ghost, a liquid fuel that might, in some distant loop, find its way back into the thumping heart of a diesel generator.
