What counts as universal waste?
Most commonly lamps, batteries, mercury-containing devices such as thermostats and switches, certain pesticides, and in many states aerosol cans. State lists vary, and some states add categories the federal rule does not.
How long can we store it on site?
Federal rules set an accumulation limit measured from when the waste is generated or received, and states may be stricter. Tracking it is part of the service, because the limit is a common finding in inspections.
Is this a service we can take on its own?
Yes. It is one of the most common single-stream engagements, and there is no requirement to move anything else.
