If the waste they're talking about would otherwise decompose in landfill producing methane, then preventing that and turning it into fuel like this is a big improvement over fossil fuels (as long as they're using green energy for whatever transformation processes they need to do to produce the fuel). One thing to take into account is that the energy density of this fuel would be far higher than batteries - while range is good enough for cars, fully electric trucks aren't quite a solved problem yet for certain load/distance combinations (there are weight limits, and at a point you have more battery than load!). This is part of the reason they're not very widely available yet. So it might make sense to go electric when the technology is closer in five to ten years, and use this apparently mostly carbon neutral fuel in the meantime.
