Universal Waste (UW) describes specific wastes that are generated by businesses as well as unregulated households. The types of waste regulated under the Universal Waste Rule (UWR) include unused pesticides, mercury-containing thermostats, fluorescent light bulbs, and spent batteries. Our goal is to reduce the quantity of these wastes going to landfills or combustors and instead treat or recycle the waste pursuant to federal regulations (40 CFR Part 273).
