Hazardous Waste What is Household Hazardous Waste (HHW)? Anything labeled as toxic, flammable, corrosive, reactive, infectious, or radioactive can threaten personal health and safety and is therefore considered hazardous household waste. Common hazardous wastes found in the home include: paints in liquid form, paint thinner and stripper, weed killer, pesticides and herbicides, brake fluid, gasoline and diesel fuel, antifreeze and solvents. These items may not be put in your garbage or recycling cart, container or drop box. These items are not accepted at the Newberg Transfer Site or at any of our recycling depots.
