You've asked a lot of questions.Why create synthetic gas for fuel when we'll have to use natural gas for fertilizer? ...
Wait ... WHAT !?! ... what are you gasifing if not organic compounds? ... because except for the water, we can burn these organic compounds directly, without wasting energy in these in-between steps ... like plastics or paper if they can't be recycled economically ...
This happened in a community up north of me ... they built a methane gas generator at their landfill, but they also expanded the recycling center and urge folks to start composting at home ... now there's not enough organic garbage to produce any gas ... waste of money ...
Decay is a biological process ... from nano-bacteria up to brown bears ... dead things are almost always eaten by other organisms ... that's because organic carbon is very difficult to create ... why photosynthesis is so super special ... why plants are the superlative evolutionary form ... humans just smell bad is all ...
It's a matter of matching up production to requirements.
Many landfills depend on anerobic digestion to break down waste. They have flares at the landfills that just burn the methane as it comes off. No value whatsoever. You also have it mixed with other stuff (old washing machines and plastics) that won't readily decompose. People also sneak in toxic wastes.
You can only really gasify organic compounds (hydrocarbons and carbohydrates). Paper is a carbohydrate with nitrogen and other compounds mixed in (cellulose might be a better way to think of it).
So if you gasify stuff as it comes in it becomes CO and H2 which can then be converted to hydrocarbons or alcohols. There is some energy loss, but at least you get something out of it. The final product is then usable and is directly usable in transportation vehicles.
You could burn the syngas and create electricity too. Depends on economics.
By doing this you also pull out the non organic and recycle (tin, aluminum, steel, etc). The ash from gasifying is great stuff for gardens too.
Lots of options, but you have to see how it fits into the bigger scheme.
