The use of reconstituted garbage (neutralysis) as an engineering construction material

The Neutralysis process is capable of transforming household and commercial garbage into a lightweight engineering aggregate. Refuse is combined with specific clay types and then pyrolysed, oxidised and fired to produce a particulate material. The potential uses of the aggregate include concrete aggregate, pavement surfacing, pavement bases and sub-bases and engineering fill. The material has been produced on a trial plant basis in Australia and may become a favoured method of garbage disposal. The potential of a locally produced material was investigated and initial results suggest that the Neutralysis aggregate is particularly suitable for use in concrete, masonry blocks and as structural backfill. Concrete mixes have been produced which exceed 50MPa in compressive strength and the material appears to possess excellent compacted strength associated with good permeability. The use of the Neutralysis aggregate makes effective use of the stored energy in waste products while producing a useful material. Local Government Authorities should benefit greatly by reducing the need for land-fill areas for waste disposal.
