Unless they grow their vegetation on site, it is too expensive to drive people’s yards clippings to their refinery and make a profit.
At least in the cities, lawn wastes are already being transported as so many people don’t compost.

This looks to me like the critical hole in this type of fuel source.
Here in the Midwest, there are a lot of cornstalks available in the fall. But they have to be baled and hauled to a plant somewhere.
Then you have to dispose of the spent corn stalks after they have been processed and fermented.
You've got it backwards. You put the refinery where the city landfill is. I've often wondered why big cities with major garbage disposal problems weren't gasifying the waste. There is a LOT of fuel value in "trash".
They’ll just mandate everyone must bag their clippings and set them out for pick up on garbage day. The expense doesn’t matter, they’ll just pass it along to the taxpayer.
