Burning crap in a bonfire or burning it in the old Rova Head furnace wasn't 'recycling' in any size, shape or form. We've been doing things differently though for almost twenty years though, and the only obvious reason its not classed as 'recycling' is whoever created teh tick box exercise never thought of our circumstances.
No. The reason the Lerwick waste to energy plant, or any other waste to energy plant for that matter, is not a recycling facility is nothing to do with circumstance or 'box ticking', it's because it isn't recycling by definition.
Recycling has to be cyclic process, the clue is in the name. If you burn something its gone, it's a linear process - once burned you've reached the end of the line because you don't get to burn it again. With recycling you never come to the end of the line but rather you can start the whole process over again from the beginning and keep on repeating it.
Waste to energy plants are waste disposal facilities, and are preferred because they extract value from the waste, but extracting value does not make it recycling.
