Teru's Trash Talk

What's in a name, or an acronym for that matter? When it comes to differentiating between kinds of thermal conversion of wastes and residuals, naming and mis-naming continues to cause rampant confusion. Part of the problem is inherent in the process; some is due to differing international conventions. Most can be laid squarely on us and our lack of attention to details. Is "Waste to Energy" just incineration as many people think, or does it also include other forms of thermal conversion such as gasification, pyrolysis, plasma...

Telling one stage of thermal conversion from another is complicated enough. When material is subjected to progressively higher temperatures, we know it'll (1) dry out, and then begin to degrade and fall apart. A bit more heat and the molecular bonds begin to break: (2) solids turn to liquids and then (3) to gas. Molecules that are no longer so firmly attached to each other start hunting for new bonds - and are particularly happy when Oxygen is there for fill the gap and "oxidize" the newly freed compounds. As this oxygen-bonding occurs Energy is released. If we keep this up, we (4) drive off and oxidize all of the molecules that break down, and the rest gets "rendered to ash". There: we've just followed the path from (1) drying to (2) pyrolysis to (3) gasification and finally to (4) incineration.

If what we want is to turn a pile of waste into Heat and Power, we can rely on highly advanced incineration. But if our purpose is Molecular Resource Recovery, we don't let everything oxidize and we siphon off the liquids and gases as foundation materials for future manufacturing. Conversion of waste for molecular resource recovery requires that we manage the process to intercept the freed-up resources before they are rendered to ash.

But let's look at the dictionary definition: Energy is Power. Most folks equate "energy" with Electricity; a few more recognize that Energy is both heat and power. It would seem logical then to say that making heat and power from waste can be called Waste to Energy (acronym WtE) or as many in Europe would prefer to say, Energy from Waste (EfW). We have enough trouble defining what is actually waste; we can't seem to agree at all on where to draw the line in defining Energy. This is a classic "lumpers vs. splitters" conundrum. Either converting any form of Waste to any form of Energy gets lumped into the WtE category or only incineration gets that buzz-word and everything else gets its own acronym. Basic Rule of Thumb: if you are going to use a Buzz Word, make sure you define it.

Hey Rube!

One path for reclaiming Money from Waste is to make a gas, clean it up, compress it, and use it for fueling vehicles and power generation equipment. This week's News contains a number of examples, each a bit different, all showing advanced levels of integration with surrounding municipal and industrial Business. We're getting closer to closing the waste-to-goods loop.
