I really doubt that more than 50 Sudanese are even aware of the «sludge» proposal (to send partially processed waste from a waste processing plant on the island of Psyttaleia, off Piraeus) and only three or four of those even care. If there is a plant in Sudan that can properly handle the sludge, then people are employed, and the treated sludge becomes a useful fertilizer. This is what was supposed to happen here. Is it possible that Sudan is more advanced than Greece? LES GROVE, Athens.
