Powered by Garbage – Seriously
Get this: A California landfill is using old trash to fuel their garbage trucks.
The fuel comes from rotting refuse – we’re talking years of rotting kind of rotting. Here’s how it works: bacteria breaks down organic scraps (no plastic!) and, over time, the garbage ferments, and releases methane gasses. From there, the methane gets pushed into tubes and sent to through a system that purifies and transforms it into liquefied natural gas.
Methane is a harmful greenhouse gas, so capturing it from the trash before it reaches the air is extremely beneficial to the environment.
Way to go, California. Wall-e would approve.
