Page 17: Disposal
Disposal Disposal Do not dispose of electrical appliances as unsorted munici- pal waste, use separate collection facilities instead . Contact your local authorities for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being. -
