Significant amounts of residual print pastes are produced by the industrial textile settlements of the Como area (Italy). Currently, these wastes are directly discharged in the sewer but it is unlikely that in the future this treatment through POTW will be further allowed. Therefore alternative ways of collection and disposal must be evaluated. The most suitable processes appear to be: drying, followed by incineration or landfilling, or anaerobic co-treatment with sewage sludge. The latter option was investigated at pilot scale and a technical feasibility analysis of the full-scale solution was carried out. Results are presented and discussed with reference to the impact that this solution would have on the performance of POTW and on the treatment costs of textile industrial wastewater.
