to as domestic hazardous waste or home generated special materials, is a waste that is generated from residential households. HHW only applies to waste coming from the use of materials that are labeled for and sold for "home use". Waste generated by a company or at an industrial setting is not HHW. The following list includes categories often applied to HHW. It is important to note that many of these categories overlap and that many household wastes can fall into multiple categories: Paints and solvents Automotive wastes (used motor oil, antifreeze, etc.) Pesticides (insecticides, herbicides, fungicides, etc.) Mercury-containing wastes (thermometers, switches, fluorescent lighting, etc.) Electronics (computers, televisions, cell phones) Aerosols / Propane cylinders Caustics / Cleaning agents Refrigerant-containing appliances Some specialty batteries (e.g. lithium, nickel cadmium, or button cell batteries) Ammunition Asbestos Car batteries Radioactive wastes (some home smoke detectors are classified as radioactive waste because they contain very small amounts of radioactive isotope americium - see: Disposing of Smoke Detectors). Smoke from chimneys Disposal Historically, some hazardous wastes were disposed of in regular landfills. This resulted in unfavorable amounts of hazardous materials seeping into the ground. These chemicals eventually entered to natural hydrologic systems. Many landfills now require countermeasures against groundwater contamination. For example, a barrier has to be installed along the foundation of the landfill to contain the hazardous substances that may remain in the disposed waste. Currently, hazardous wastes must often be stabilized and solidified in order to enter a landfill and must undergo different treatments in order to stabilize and dispose of them. Most flammable materials can be recycled into industrial fuel. Some materials with hazardous constituents can be recycled, such as lead acid batteries. Recycling Some hazardous wastes can be recycled into new products. Examples may include lead–acid batteries or electronic circuit boards. When heavy metals in these types of ashes go through the proper treatment, they could bind to other pollutants and convert them into easier-to-dispose solids, or they could be used as pavement filling. Such treatments reduce the level of threat of harmful chemicals, like fly and bottom ash, while also recycling the safe product. There is a recycling center facility in Oxnard, CA. The city does not charge for any hazardous materials being disposed of, but there is a limit to how much you can bring per month. Other than hazardous waste, the city also allows you to dispose of electronic waste,
