Some business types and processes that may produce solid waste:

The list below contains some wastes that your business may generate.

Waste Materials

office paper, cardboard, and plastic, metal and glass food and beverage containers;
food wastes from cafeteria or break room operations;
used engine oil, anti-freeze, batteries, and similar wastes generated from fork lifts, cars and trucks;
office equipment and appliances, such as computer monitors and hard drives, printers and copy machines, televisions, and microwave ovens.
packaging from materials received at your facility, such as foam, strapping, and lumber
wastes associated with heating and air conditioning systems, and building maintenance;
material left-overs and cut-offs from production and packaging; and
used process chemicals, sludges from process tank clean-outs, and other wastes generated from production processes.

expired shelf life;
off specification for the process it was intended for;
no longer needed due to production process changes - as a result of a change in your business products or substitution with a less toxic material.

Include anything you may have at your facility that you are not sure what it is, such as an unlabeled barrel or other unlabeled container. Containers should be examined, opened and sampled by a properly qualified individual.
Open metal containers only with non-sparking tools, in case contents are flammable. Don't smell unknown chemicals, and take precautions to prevent contact with eyes and skin.
If the container is in poor condition, or damaged in any way, seek expert advice before moving or touching the container. A barrel with the top or sides pushed out, for example, may indicate the contents are under pressure, and opening it could be dangerous.
If the container is not in good condition, make plans to put the original container into another larger (over-pack) container. Again, get expert advice first.
