(US5352444-A)      Biowaste treatment agents (I) comprise (A) a surfactant which is 1.0-99% of (I) and is pref. a mixt. of non-ionic and amphoteric surfactants; (B) a metal component which is a source of (a) Zn or (b) Cu or (c) Cu with Al or Fe; (B) comprises 0.5-85% of (I). Pref. (B) is (a) or is Cu sulphate and/or Al chlorohydrate.    (C) an aldehyde in amts. of 0.1-80% of (I).Cpd. (C) may be benzaldehyde (esp. pref.) or acetaldehyde, glutaraldehyde, citral or decanal, and opt. (D) an aq. carrier, and (E) a proton donor (citric acid or a deriv.).    (JP8503162-W)      Biowaste is treated with a polyfunctional treatment complex (I) comprising a synergistic combination of materials effective in wetting and penetrating the waste in amts. sufficient to neutralise offensive substances in, and generated by, it; and to disrupt the processes by which the offensive substances are formed.    Pref. the prim constituents of (I) (all polyfunctional) are: (a) pref. a surface active treatment agent/synergiser (pref. a soap, rosin oil or tall oil, alkylarenesulphonate, alkyl sulphate, straight chain hydrophobe, hydrophobe with prim. and sec. branched gps., long chain acid ester of polyethylene glycol, polyethylene glycol ethers of an alkyl phenol, long chain alcohol or mercaptan, fatty acid diethanolimide, block copolymer of ethylene oxide and propylene oxide, quat. NH4 cpd., (amino)carboxylate, acylated protein hydrolysate, lignosulphonate, alkylbenzene sulphonate, petroleum sulphonate, dialkylsulphosuccinate, naturally sulphated oil, phosphate ester, a polyoxyethylene, ethoxylated alkylphenol or aliphatic alcohol, carboxylic ester, an alkali, a phosphate, silicate, neutral double salt, an acid, or an insol. inorganic builder); (b) an oligodynamic metal or source (esp. of Cu, Ag, Fe, Zr, Al, Mg, Mn or Zn; a colloidal metal; or a halide or other mineral acid salt, carboxylic acid salt, an addn. prod., an oxide, mineral, a waste or recycled metal, or a variety of colloidal quartz in which 1 or more oligodynamic metals are present as impurities); and (c) a synergisable biowaste stabilising and vapour neutralising reactant/photosensitiser (pref. an aldehyde esp. MeCHO, glutaraldehyde, anethole, carvone, citral, decanal, limonene, pentaerythritol, or Me anthranilate, partic. PhCHO).    ADVANTAGE -   The polyfunctional biowaste treatment complex (I) replaces conventional surfactants, also providing biowaste stabilisation, retarded release of pollutants and neutralisation of released pollutants (by sequestration, complexing etc.). In addn., the potential value of biowaste components is augmented, treatment times are reduced, and dewatering and concn. are facilitated.
