A. This sounds like a good and useful idea for a thesis, K.R., but c'mon :-) Are you expecting to just provide a title, and then have a generous reader write it for you? :-)
Please start it off with an abstract, and then post some specific questions with what kind of info you would like to get, and I think people will be happy to help! Thanks.
Regards,

Q. Hello Mr.Ted, Zinc Phosphating Sludge is heard to be useful in manufacture of bricks. Is it true? We do Zinc Phosphating process and after ETP treatment of the effluents, want to approach an interested concern for making bricks. But before doing that, at the outset want to know if this thinking is meaningful.

A. Hi Subhajyoti. Things are different in the USA than in India. Here our EPA was very concerned about the possibility of the generators of waste contracting for disposal with low-priced fly-by-night companies. They therefore ruled that the generator is FOREVER responsible for the waste -- and this stopped the whole idea of Industrial Waste Exchanges dead in its tracks. Nobody will ship their waste to a third party for re-use considering the unbelievable level of exposure this creates. Could you imagine someone building a skyscraper with bricks from your zinc phosphate sludge, and you being responsible for removing those bricks? :-)
Yet another thing that happened in the USA was an incident where contaminated waste oil was used to oil the roads in a town, with the whole area permanently evacuated and becoming a ghost town (Times Beach, MO). You'll learn nothing about re-use from the USA. We landfill our waste products, period. :-(
