A hazardous waste consultation aimed at a small sector of the waste sector has been launched this month by the Environment Agency (EA). The consultation ends November 28 2007 and is aimed at producers of hazardous wastes and hazardous waste management operators. An Environment Agency spokesman said: The aim of the consultation is to ask producers of hazardous wastes whether the guidance achieves the desired aim of providing clarity on how to classify and code output from physico-chemical treatment facilities. For example, an earlier draft of this guidance required all hazards in a waste to be treated to make the waste non-hazardous. We have accepted that when certain treatment activities are carried out, there well be a degree of dilution of some of the dangerous components as part of the treatment process that will result in a non-hazardous residue. The guidance explains where this is acceptable and where we also consider that insufficient treatment of dangerous substances has been carried out such that the residue will remain hazardous. The EA hopes that the consultation will bring better clarity in the classifying and coding of hazardous waste so that treatment activities may be improved and to facilitate the development of new treatment technologies.
