What is considered bulk items?
Items that are too large to fit in your trash container. Bulky waste items include discarded furniture (couches, recliners, tables), large appliances (refrigerators, ovens), and plumbing fixtures (bathtubs, toilets, sinks).
A large amount (30-60%, depending on area) of bulky waste is picked up by scavengers before it is collected. Branches, brush, logs and other green waste are also categorized as bulky waste, although they may be collected separately for shredding and/or composting.
