Not good returns - EXCELLENT returns. Here in "old Europe" we can get a feed-in rate to the grid of about $15c/kWh! Per kg of plastic, that's twice the revenue than selling diesel at $75/barrel.
And it's why JBIIE won't be down at $1 for much longer ;-)
Bingo. There is more natural gas produced than needed by the processor.......that will be compressed and used to generate electricity for the entire facility........z
