compost heap question

I had hoped it might not be necessary to say it yet again, but here goes: I possess a considerable amount of the literature of the Soil Association. I have read it all avidly. I have studied their website. It is all very interesting to read, but nowhere did I find a definition of what the actual formal definition of "organic gardening" is, except perhaps "To follow the rules laid out by the Soil Association". That is *not* a scientific definition. Perhaps you should drop them an email and ask them to answer your specific question, I'm sure they'll be only too pleased to oblige. I would have thought that if anything was organic, coal was. Now do you understand my problem? No, I don't. Not all coal is 'coal'. Your bog-standard lump of house coal, straight out of the ground, is coal. The stuff that's been formed into neat little ovals may well contain additives that enhance or retard its speed of burn. That might or might not be true. I suspect that it contains only a cement to allow the dust to hang together. But if you are unhappy, please feel free to replace the word "Phurnacite" by the word coal and reread the whole thread. As it happens, Phurnacite ( at least the modern version of it ) contains no additives or cements at all - so the only issue of concern would be the concentration of residues in the ash. In spite of the fact that the plastic yields only gases in its combustion product, and therfore leaves no residue in the solid ash? In other words it doesn't matter what you chuck into the atmosphere. That kind of negates the principle a bit, don't you think? Please don't put words into my mouth. It is a technique which is guaranteed to fail. It was the *coke* which you said wouild magically be rendered "inorganic". Ah Franz....I was trying to put thoughts into your mind - is that too a technique guaranteed to fail? Of course the *atmosphere* will be given a burden of possibly harmful gases. OK, so can you now see a correlation forming here? Let's take a pile of coal and set it burning. If left alone is would produce a pile of ashes which would be considered fit for organic use. If, however, you tossed a plastic bottle on the fire, you'd render the ashes unsuitable for organic use. This is because the coal ashes would be contaminated with the residues of the burnt plastic ( complete conversion requires a high temperature, controlled burn ). Assuming you could supply that, the emissions of the gas produced would mean that in order to attain your pile of ash you would still have unnecessarily contaminated the atmosphere. Maybe that's why the concept of organic gardening seems to evade you - it's more than picking packets off a shelf, you have to think a bit further down the line.
