Abstract
A study on the possibility of using biosolid, derived from an industrial
wastewater plant, in blends with cement pastes to produce manufactures suitable
for construction, has been carried out. In the present work a screening on the
chemical-physical characteristics of the biosolid is reported; also described is the
methodology used for the preparation of the concrete/biosolid samples and the
set of tests applied to evaluate the eco-compatibility of the mixtures. An ESCA
(Electron Scanning for Chemical Analysis) study was carried out for the
chemical characterization of the composite material.
Keywords: biosolid, wastewater plant, concrete, ESCA, eco-compatibility.
1 Introduction
Environmental health has become an important issue for industrial policy
especially in those areas with a high concentration of industrial plants and
pollutants. This is the case of the area located in the eastern coast of Sicily (in the
industrial area of Priolo near Siracusa) where the high concentration of
petrochemical plants makes the process of environmental recovery very urgent.
The waste water treatment plant (run by I.A.S- Industria Acqua Siracusana,
S.p.a) collects both industrial (mainly petrochemical) and civil discharges. This
plant has a treatment capacity of about 4300 m3/h and collects an amount of
biosolid of about 60.000 ton per year. At present, 60% of biosolid is recovered
and used as a component for the preparation of cement while the rest is collected
in landfill. Our attempt consists of trying to use biosolid in new cement
