Posted By: SteveZRecently the incinerator proposed for Cornwall has had its planning permission revoked, so we can look forward to another round of legal battles and more wasted money, wasted unless you are in the legal profession of course!Does anyone have in-depth knowledge of the process of slow and/or fast pyrolysis? It seems to be a good technique of dealing with most of the organic rubbish which finds its way into landfill or the incinerator.Before the flood of comments about reduce, reuse and recycle come in, I would like to say that I agree that is the best way but, in the real world, we need a better way to dispose of the rubbish in the near future.In pyrolysis, the organic rubbish is ground small and dried to remove most of the water content, then is heated in an oxygen deprived atmosphere. This produces gas, oil and a solid char. The proportion of each can be adjusted by changing the conditions and is also dependent on the raw material. The gas produced can be used to heat the process plant in a closed loop and any excess modified separately into liquid fuel. The oil can be used as is or refined into diesel fuel. As the exhaust gases are recirculated into the plant there are no or very few emissions from the plant. The char is, according to the trial results, a very effective slow release fertiliser and soil improver.I don't think pyrolysis plants are available off the shelf yet and the technique is not fully sorted, but it seems to offer such possibilities that I am surprised (or suspicious) that there is not more publicity about it.if it all sounds too good to be true, then maybe we could dig a little deeper and see if this is one which is actually as good as it sounds

The company was founded in 1992 and as early as October 2001 was granted the Integrated Pollution Prevention and Control authorisation (IPPC). The annual processing volumes are 8 thousand tons of waste mainly from medical origin."
