Our US Bases generate “shit tons” of waste; I mean that in the literal sense. Our shit has to be processed in WasteWater Treatment plants...
In addition to that, there is TONS of waste in terms of other organics (everything from food scraps to grass clippings).
All = Energy
Literally, we pay tons of money to deal with this waste; why not convert it?
The “Green People” have been pushing advancements in BioGas; it can be done, but it’s not economical.
It takes Million$ in infrastructure, for one thing.
Also, this type of process is heavily dependent on temperature...
The breakdown of organics to gas is most efficient within certain temperature ranges.
With the BioGas plants on the surface, there are large portions of year where the temperature is too cold...
... to efficiently convert waste to gas. The result is, a huge portion of the gas must be used to heat the plants, enabling gas production to continue.
It’s highly inefficient for many locations.
The cost comparison (producing BioGas vs purchasing NatGas) isn’t feasible.
💡: We have a TON of formerly productive oil & gas wells that need to either be brought back into production, OR plugged.
It’s a huge problem; a huge Cost to plug.
Can organic waste be injected/digested in production zones below surface?
If I were to look at the economics of doing that (on my own) I’d probably say... “Screw it - I’ll just invest in a new oil/gas well.”
However, if I were to approach it as a “Waste Disposal” contractor - ie paid by USAF to dispose of the waste, those economics change quickly.
It may not work across the board, for all bases.
But for the many bases that are near the oil & gas fields... it’s a “Green Idea” that just might work.
What do the bases in OK/TX (& others) pay annually for this type of waste disposal?
What do we have to pay to plug old wells?
If the $’s work, it shouldn’t be too tough getting DoD + EPA cooperation to make it happen.
