While dumpsters are great for most types of waste, there are a few items you should never toss in. These include hazardous materials like paint, oil, chemicals, and propane tanks. Electronics, batteries, tires, and medical waste are also typically restricted by local disposal laws. Disposing of these items improperly could lead to extra fees or even legal issues. Be sure to ask your rental provider for a list of prohibited items before you begin loading up your bin — we’ll always guide you on what’s safe to throw away.
