Dear Sensible People,
 
There has been an outbreak of "incinerator fever" within the bureaucratic decision-makers of England.  The symptoms are the building of huge (and I mean huge!) industrial plants that actually burn "organic and biodegradable waste" along with anything else you can imagine that is put into the rubbish bin at home and at work thereby producing a lethal cocktail of airborne pollution (they admit this - one incinerator alone annually produces 180 tonnes nitrogen oxides, 26 tonnes sulphur oxides, 91 kilotonnes of carbon dioxide, several tonnes of carcinogenic particulates, 0.1 tonnes of hydrogen fluoride, and 'small amounts' of dioxins).  The 12 existing incinerators in the UK already kill 88 people a year from the airborne emissions and the authorities are urging for more of them!  The residues left from incineration are dangerously contaminated with heavy metals and constitute a grave problem for their safe disposal.  The authorities at Cleveland (UK) fell for the idea of an incinerator (energy from waste they called it) and in the first year of operation the people of Cleveland began recycling much more leading to a shortfall of waste which meant that the incinerator operators were unable to burn it so Cleveland had to pay the operators 147,000 pounds Sterling on top for failing to meet contractual obligations.  Now, of course, Cleveland do not want the recycling message to be heard.
 
I have become embroiled in the campaign to fight incineration in the beautiful county of Cornwall in the UK where there are plans afoot to impose another such incinerator.  My approach has been to tell anyone who will listen about anaerobic digestion and the need to sort rubbish out at source so that greatly beneficial recycling can happen.  I have told people about the advances in Scandinavia where anaerobically derived biogas is used for motor vehicles (the ZEUS Project) and electricity generation, and how the residues, post digestion, are used for precision farming without affecting or polluting water supplies.  Cornwall is a popular tourist attraction and is predominantly a rural community where there are literally thousands of tonnes of animal manure constituting a problem currently dealt with by "muck spreading" on the fields.  TB has broken out and cross infection is at work using this method of disposing with manure, but TB is blamed on the badger population which is being culled.  Human excreta at various stages of treatment (derived from cesspits) is also spread on the land.  Neither animal or human waste is currently considered by the authorities to be a problem and is scheduled to continue to be dealt with as is.
 
My company, Ico-Tech, (www.ico-tech.com site under construction but I can be reached at jthomas@ico-tech.com ) is now (March 20th) relocating to the frontline at Cornwall to fight the incinerator monster and introduce anaerobic digestion as an alternative.  The decision makers of Cornwall know nothing at all about anaerobic digestion and have been greatly misinformed by "experts" who are hard at it selling incinerators at 50 million pounds Sterling a go.
 
Cornwall has an extra population of 4 million tourists each summer with all their waste as well to take into account.  Cornwall can grow an immense supply of energy crops to add to the huge feedstock reserves.  The European Union has decreed that by the year 2005, no organic waste may go into landfill, and Cornwall's landfill sites are almost full anyway - hence the incinerator idea.
 
The population of Cornwall do not want the incinerator but are told there is no alternative.  I know this to be wrong having visited and seen for myself the anaerobic digestion technology at work in Sweden.  The media, as yet, ignore what I have to say on the subject.  However, the population of Cornwall I have met and heard about in the media are ready to institute sorting of waste out at source for feedstock and other recycling purposes.
 
Such is today.  I ask you for advice, comments, suggestions, support (technical and otherwise), & general help both tactical and strategic.  Cornwall has an ambition to become a Green Peninsula and is about to throw it all away forever in a dirty furnace.  I cannot stand by and watch this lunacy have its own way.
 
Thank you.
