Great point. This isn't like biodiesel or ethanol, where the co2 would end up in the air anyway. A methane generator actively creates a carbon form that is significantly worse for the environment.
No. This process is 100% carbon neutral. It recycles the carbon already in the pig manure as opposed to natural gas which is a fossil fuel and adds to the carbon cycle.

Is it true methane is so much worse a geeenhouse gas than co2 ("20x")? Wouldn't that mean him turning methane into co2 is not just carbon neutral, but great for the environment?

It's true and it actually has a GWP[0] of ~80 over 20 years (so over 20 years a given mass of methane traps 80 times as much heat as the same mass of CO2), although it degrades back to CO2 and water in 12 years. So yes if you're releasing t…
How is this practice even legal? Could auto manafuctirers do the same thing? I'm sure they discourage aftermarket programming and whatnot, but using DRM to prevent DIY repairs is bringing things to a whole new level.

My dad is a mechanical engineer who loves cars. I spent my youth listening to him lamenting the fact that modern cara have too many electronics and DIY protections. That you can't even make an oil change without also notifying the computer, the interface for which is proprietary and only sold to licensed dealers, or the car would refuse to run because it would think its oil is bad. He reminisced about the good old da…
I know people who bought brand new 2016 BMWs and Mercs, and the first thing they did was mod them - and the computer seems to work fine with whatever silly things they did with the engine.
So I don't think it's all that bad.

[citation needed] There is no vehicle on the market (that I know of) which will refuse to run without an oil change. On my 17 year old BMW and 2 year old VW, the oil service indicator is just a reminder, a courtesy. On the BMW I can reset it with a paper clip. On the VW I can reset it on the screen on the dash. Honestly, most of the major things that go wrong with cars these days are still mechanical, and are still f…
You haven't experienced it, but this sort of thing does exist. Want to replace your relatively simple Volvo throttle body with a junkyard pull? Nope, it's programmed to your VIN. Similar for many radios. And the notoriously glitchy matrix display on the dash cluster of 90s BMW's. Also, PCM and body control modules, and more I've forgotten.

Not sure about the laws in the US, but my wife works as a chemical engineer at a sewage treatment plant here in Sweden and they run _all_ incoming sewage through a aneorobic digester. This generates enough methane to run all the busses in Stockholm and then some. Our car also (VW Passat) also runs on bio-methane. Important to note that this is 100% carbon-neutral since it uses carbon already in cycle, as opposed to f…

Yes, though if you use the aneorobic digester to make the methane in the first place, it's moot.

No. This process is 100% carbon neutral. It recycles the carbon already in the pig manure as opposed to natural gas which is a fossil fuel and adds to the carbon cycle.
The main question to me would be how much becomes atmopheric from raw pig manure versus digester.
With digester: manure -> compressed methane -> combustion engine -> energy + Co2.
It's such an enormous win-win it's strange not everyone is doing this.

It's basically free energy.
