I looked into getting a pellet stove for my wood-shop when I lived up North (1995). At that time pellets made from peanut shells were available.
It seems to me you could pelletize everyday trash. I bet there is a LOT of energy in the wax coated paper cups and containers that most fast food places use.

Sounds like the start of a business plan. I bet that recycling depots would love to find a market for those things.
