10 04 Waste from thermal processes in lead metallurgy

The processes of smelting, refining, and heat treatment of lead and its alloys are accompanied by the generation of specific metallurgical residues classified under code 10 04 Waste from thermal processes in lead metallurgy.

This category includes lead slags, dust from gas cleaning systems, filter residues, as well as other non-hazardous wastes in this group generated during related technological operations and equipment maintenance. Since some of these substances are highly toxic and contain hazardous heavy metals, they require strict control from the accumulation stage at the facility.

Environmentally sound management of such waste requires compliance with the strictest industrial safety and sanitary regulations, as lead-containing dust and metallurgical residues can contaminate workplace air, pollute soil, and pose a threat to human health and natural ecosystems. They are strictly prohibited from being left in open areas without protection from precipitation, discharged into municipal sewage systems, or transported to general waste landfills.

Enterprises are required to arrange sealed temporary storage in specially designed closed containers or protected storage facilities and transfer these hazardous materials exclusively to licensed operators.

The most rational approach to managing these wastes is secondary pyrometallurgical processing, recovery of valuable components, or advanced chemical stabilization instead of direct disposal. Lead-containing dust and slags are most often returned to the production cycle for the recovery of pure lead and associated non-ferrous metals, while other non-hazardous wastes and stabilized non-recoverable residues may undergo neutralization or be sent to specialized facilities for safe disposal.
