The crossed-out wheeled bin symbol indicates that the
item should be disposed of separately from household
waste. The item should be handed in for recycling in
accordance with local environmental regulations for
waste disposal. By separating a marked item from
household waste, you will help reduce the volume of
waste sent to incinerators or land-fill and minimize any
potential negative impact on human health and the
environment. For more information, please contact
your IKEA store.
