That is a very good reference and shows how valuable that product is. It is mainly tilled into the soil to keep the soil natural, but can be used to make ethanol if corn is too expensive. During our last so called energy crisis President George W. Bush smartly pointed this out. I am not a fan of his due to his fondness for crony capitalism though. He also amplified spying on Americans rather than foreigners.

It is not very valuable. Look at the

https://en.wikipedia.org/wiki/Corn_stover#Composition_and_properties

again. 3.1% protein, the rest various things you don't want. If you till it into a field, it will take much longer than one season to decompose, so you cannot do it every year. "Cellulosic" ethanol is way, way more expensive than regular corn ethanol, because you need to use a ton of expensive enzymes to break the cellulose into usable starches and sugars first.

I already did, in several posts. To summarize, there is still potential for liquid biofuels, but not for biogas (as in methane) the way it is done now.

There is also unlikely to be a LNG on a scale of a car or truck, because it is a cryogenic liquid that cannot be stored without evaporative loss. Converting to DME (dimethyl ether) or methanol is a better idea.

CNG and LNG are a growing truck fuel around the world. If something is better let it compete. Show me. I have heard many people promoting methanol but no results for transportation.

Corn stover IS tilled into the ground every year. It preserves the tilth of the soil and degrades. I have seen trees growing in a line on dead trees in rain forests. Plants feed off of dead plants sometimes even without normal soil. https://en.wikipedia.org/wiki/Tilth

"Can" does not translate to "should" in the EU. AFAIK, there is still a glut of glycerine the "1st gen" biodiesel works produce.

I only started talking about liquid biofuels after you said my knowledge about them has a gap.

I was using the term biogas which, I think, you interpreted as a liquid. Regardless, we are hopefully now talking about gaseous fuel and or liquid fuel made from biological sources such as waste streams of some kind or any available organic matter such as peat, or cellulose. I don't see any problem with using glycerine as heating fuel. Maybe you have an argument against it.

No, I am not American enough to confuse gasoline with actual gas. Pyrolysis into syngas followed by GTL works, but is supposed to require something like $120/brl oil to be profitable? If you consider peat a renewable fuel, you should apply for political asylum in Finland. They'll love you. Elsewhere, no so much I don't have a problem with burning glycerine for heat, but the EU apparently does. They fail to classify it as a renewable fuel, even if it comes out of veggie oil biodiesel production as a waste byproduct.

Japan designated DME as their official diesel replacement fuel for heavy machinery. At some point, Mack Trucks in US jumped onto the bandwagon. Dunno if they are still there. CNG is OK, but rather bulky for the same amount of energy.

I live in an area where corn and soybeans are grown intensively. Crop rotation is a good idea, as is using clover or other cover crop in the late fall. In reality, most farmers do not follow what others consider best practices. They do what works for them. They often use too much pesticide or nitrogen fertilizer. 

Do they follow the crop rotation in Russia and use cover crops as you imply? If so, good for them. The water systems of Russia benefit as does the ground water. 

Another advanced form of large scale agriculture is called no till, which recommended by the experts but not often used. Then there is the use of too much chemical control of weeds and insecticide which also pollute the water and kill honeybees etc.

I don't really know what they do. Russian prowess in agriculture is a very new thing, thanks to your 2014 sanctions collapsing the ruble. Before 2014, Russia was a net importer of agricultural goods. Now - #1 worldwide in wheat and other grains, kicking the US off the top spot. See how karma is a bitch? I suspect Russian agriculture to be a lot more like Canadian than yours. Corn only grows in southermost regions and sugarcane not at all, so there is not too much to till.

Crimea is not very agriculturally significant, with exception of wine. Very little water, lots of rocks.

Yes, US also does a lot of corn and soy and Russia just grains. Too cold, but hoping for some help from global warming, should there be any truth to that.

Fun fact - Crimea is at the same latitude as the northermost part of US-Canadian border.

Most promising for bulk agriculture is the soil type called the

I am not available of any road vehicles that use LNG directly, though. They do have a railroad locomotive that does.

UPDATE: https://uic.org/events/IMG/pdf/03_rzd_natural_gas_trains_ivanov.pdf

They are gas turbine / electric hybrids, so it is just a ploy to reintroduce turbine locomotives to haul more freight.

Nothing unsustainable about the process itself. If only weren't oil and gas companies who license it so cheap and went after the cheapest feedstock they could find. Which happens to be palm oil right now.

Biogas does not really use "waste streams" like you think they do. In reality, do they use misc. plant matter that you could also feed to livestock. The German nickname for a biogas digester plant is Betonkuh (concrete cow) It really is an emulation of ruminant digestion system at the moment. Possibly it may eat what pigs would, but that's about it. So, there is no way to get it to digest what a similar process inside a real cow or pig already did. I presume that to be the basis of the whole "cow fart greenhouse effect" scare.

 a lot of biogas produced in the UK is from household organic wastes and waste from intensive farming (poultry and pigs) The only alternatives are composting. Spreading raw on the land causes loads of odour complaint issues. Anerobic digestion to produce biogas is very neet. 

You get a good supply of gas. Estimates are the Uk has a potential for about 150 Twh a year (1/6th of domestic needs) 

The residue, with most of the nutrients retained is easy to spread and low odour.

The rise of agriculture and the influence of genetics and culture (gene–culture coevolution) continue to affect modern humans through alterations in nutrition, a predisposition to obesity, and even exposure to new diseases.

Selective "breeding" of crop cultures has made a truly dramatic impact, already.

It is just a slower process compared to what lies ahead.

Europe has participated, and will participate in the future.

It does not have to involve foodstuffs.

It will affect the energy industry.

Birdshit (guano) is pretty much wet mineral ash. There is nothing left in there to burn, not to speak of  gassing.

Do you have a separate collection for compostables, like grass left from mowing lawns? If yes, this is what they throw in there. No current biogas setup I am aware of works on pure refuse, only on a small fraction.

Unlikely that you get far making biogas with human or pig crap alone also, but you can burn these if they are dry enough. Works about the same as peat or lowest grade lignite. Interestingly enough, GreenPeace objects to trash incineration in only two countries - Russia and UK. In UK case, this appears to be due to availability of household-scale incinerators.

Nobody is actually interested in renewable transition? It is purely a neocolonial plot of taxing the developing economies for developing, while also sneakily expanding the domestic taxation base at the cost of the middle class.
