Dr Paul Connett is a Sussex-born scientist whose message for his home county is that burning rubbish to get rid of it is dangerous.
Based on his experiences in the United States and Canada, he believes incinerators produce a mixture of chemicals which can be harmful to humans and animals.
All this is uncontaminated food and drink for the Ouse Valley campaigners who do not want an incinerator near their homes.
But it conflicts strongly with the evidence from authorities which have built the latest high tech incinerators at places such as Lewisham in south London, who say there is no pollution problem at all.
East Sussex County Council and Brighton and Hove City Council have a problem. Landfill sites are fast running out and recycling rates wont fill the gap.
Even if they doubled or trebled, there would still be large amounts of rubbish which could not be recycled.
Before any decision is taken on building an energy from waste plant in the Ouse Valley or elsewhere in Sussex, an independent report is needed on whether there are any dangers.
And campaigners against incineration need to explain exactly what they would do with the significant amounts of waste which, with the best will in the world, cannot be recycled or composted.
