Chemical or Bacteria that will decompose paper -- 2

I have a large amount of documents which I would like to destroy but do not wish to use traditional shredding methods. Instead, I would like a chemical engineer or similar professional to advise or produce a non toxic chemical or bacteria that could be added to water in order to rapidly decompose the paper and render it destroyed such that the printed information on the paper is not retrievable i.e. to be a viable alternative to traditional shredding. The solution advised or prepared should be a non toxic substance that does not require refrigeration. By adding the substance to a basin of water containing circa 0.5kg paper, the paper should become pulp within 30 minutes. Ideally to an extent that the resulting solution can be drained in domestic drainage without negative environmental effect.
