This looks pretty nifty: A company called Prometheus Energy Co. will be setting up a facility that takes waste gas from landfills (ew) and refines it into liquid natural gas, which can fuel vehicles (at least vehicles that have undergone a fairly expensive conversion). Allegedly the resultant gas will be cheaper than diesel, and Prometheus will also set up a fueling station.
The LNG can also be created from "excess gases at coal mines, dairy farms or abandoned natural gas wells."
These waste-to-fuel projects are the kind of no-downside strategy I hope we see a lot more of.
