4.1. Potential for hazardous waste classification
Although household wastes are excluded from the definition of
hazardous waste under US federal rules, knowledge of the potential
for consumer electronic products to trigger hazardous waste limits
is important because (i) some US states (e.g. California) do not
adopt this exclusion, (ii) products discarded from non-household
sources (e.g. outdated or unwanted products from a business entity)
are not excluded, and (iii) local governments often target household
hazardous wastes (HHW) for collection and management as
hazardous waste.
