Some interesting coal technology;

Will Komex need metallurgical coke? Can Phoenix use and sell liquid fuels? Does New Orleans have tons of wood debris? Just pure speculation, but food for thought.
-------------------------------------------------------------------
Process for converting coal into liquid fuel and metallurgical coke
A method of recovering coal liquids and producing metallurgical coke utilizes low ash, low sulfur coal as a parent for a coal char formed by pyrolysis with a volatile content of less than 8%. The char is briquetted and heated in an inert gas over a prescribed heat history to yield a high strength briquette with less than 2% volatile content.

What are synthetic fuels?

Synthetic fuel, also known as synfuel or Fischer-Tropsch liquids, is fuel such as diesel and jet fuel that is made from coal, natural gas or biomass, instead of oil. These are clean--burning, high-performing fuels that run in existing engines.

Biomass Fuel??

DISCARDED WOOD ISN’T WASTE ANYMORE

According to Vince Promuto, a Bronx hauling company
owner and one of SPM’s joint venture owners, the low
price of oil is keeping the markets down for wood fuel.
“But it’s a business that’s just waiting to explode, just as
soon as the price of fossil fuel goes up again,” he says.
From compost piles to railroads
How do wood chips and particles help cornposting operations?
In a process known as “static pile aeration,” wood
acts as a bulking agent, speeding up the natural cornposting
process by dispensing air evenly through a pile of sludge.
In Philadelphia, the Water Department’s sludge management
unit runs a large-scale wood/sludge composting operation,
and the wood chips can be used over and over
again. And Littleford Brothers (Florence, Ky.) manufactures
a continuous mixer-conditioner that blends the sludge
and wood into compost in an even quicker process.
One of the most fascinating recycled wood products is a
reformed railroad tie - that’s actually better than a brand
new one! Several railroad companies trade in their old
crossties at Cedrite Technologies (Kansas City, Kan.),
where they are ground up, mixed with a binder, put in a
mold, and cured in an oven. The finished product? A perfectly
shaped railroad tie, which actually lasts longer than
those made with virgin wood.
According to Frank Brogdon, Cedrite’s vice president of
sales, when railroad ties get old, they tend to dry out, split,
and decay. But recycled railroad ties, because they are
more dense, don’t bum as easily, split from spikes, or rot
like virgin wood. Cedrite plans on producing 600,000 of
these ties a year. - Kathleen Meade
