Abstract
The surface treatment industry generates large quantities of metallic hydroxide sludge from the purification of waste water. In order to comply with environmental constraints, this sludge must be eliminated without causing adverse effects to human health or to the environment. In 1991 the European Commission modified the 1976 general directive on waste, by adopting the principle of prohibiting, wherever possible, storage or dumping, and prioritising recycling, re-use and recovery. The present research project now terminated was part of this initiative. It proposed a global approach to hydroxide sludge management that could be adapted to surface treatment workshops of all sizes, by developing technically viable and industrially cost-effective methods for drying, inerting and recycling.
