The best disposal method for hazardous waste is recycling or donation, if possible. That way, the world can reduce its consumption of raw materials and the volume at which materials have to be treated and disposed of. If recycling or donation is not an option, most waste can be disposed of through landfills or incinerators, but their collection and treatment are separate from regular day-to-day waste disposal. 

Exterior paint contains a higher level of VOCs, which can be dangerous if you’re exposed to it for a long period of time. The good news is that paint’s toxicity reduces significantly once fully dried and cured. Do not keep open exterior paint cans in your home, basement, or garage, exposing your household to harmful chemicals over time.

Lead toxicity comes from inhaling lead or consuming it. Before the 1980s, when the government banned lead from consumer use, it could be found in paint, plumbing, pipes, ceramics, and even gasoline. Lead paint is toxic for the same reason lead itself is toxic, which is why lead poisoning from paint presents the same as lead poisoning from water or food sources, with a slight increase in respiratory symptoms vs. digestive symptoms. Lead paint is most dangerous when it’s old and peeling, cracking, or otherwise disturbed. This increases the concentration in the air and, therefore, in breathable air. 

You can sell a house with lead paint, but there are several requirements. If you are aware that lead paint exists anywhere in the home, you must disclose that to potential buyers. Required home inspections will often uncover lead paint, especially for older houses where lead paint may still be a problem. If you have taken steps to encapsulate lead, you should provide buyers with full documentation of the project so it won’t cause any problems later on.
