It is mainly produced by industrial activities (pharmaceutical, chemical, petrochemical and automotive), but also concerns households and communities (paints, cleaning products, etc.). 

Due to the particular environmental and health risks it represents, hazardous waste is subject to special management rules, and reinforced administrative control (production, storage, transport, treatment, cross-border transfer).

Examples of hazardous waste:

• used oil
• used acids
• used solvents
• paint sludge
• oil tank bottoms
• obsolete pesticides
• toxic gas waste.
