(ZA9702169-A)      Composite bioreactor (10) for the remediation of soil containing organic and/or metal species, contains sulphur oxidising bacteria (SOB) bioreactor (12) on top of a sulphate reducing bacteria (SBR) bioreactor (14). The SOB reactor comprises soil to be remediated containing suitable micro-organisms to react with and degrade contaminants and the SBR bioreactor comprises a trough (18) to support soil on permeable membrane (16) allowing passage of liquid but not soil, and containing sulphur reducing bacteria; and liquid and nutrient supply to promote growth of both types of bacteria within composite bioreactor. The method for remediation of soil containing organic and/or metal species is also claimed.    USE -   Remediation of soil polluted by toxic metal and organic contaminants.    ADVANTAGE -   The method is efficient and economic. There is no requirement for heavy capital plant expenditure. The bioreactor can be re-used after decontaminated soil has been removed.
