There are over 100 million metric tons of biomass waste produced in the United States annually. How many barrels could you make out of that?
Probably not enough since you have to build the plants and transport the materials and that would take more investment capital than there is. At the same time the plants are buing built, note, the cost of building the plants will increase and continue to increase rapidly due to the increasing cost of energy. This could have been done starting 30 years ago. It cannot be done now, it's too late.
Doing the math off of post 15, 100MM mTons works out to 300MM bbls. of oil, or about 1 months annual consumption for the entire world.
Not bad. Not to mention the gross revenue from 300MM barrels of oil being sold, and the small fee for processing the waste products...
