Are there any types of trash (bagged) that garbage collectors will not pick up? Or bill extra charges for? Or will there be a difference depending on number of bags on cost?

That depends upon your community and trash collector. Call the trash collector.

That information is probably on its web site.

The types of trash that garbage collectors will not pick up or may charge extra for can vary depending on the specific policies and regulations of the waste management company in your area. However, I can explain a general guideline to help you understand what may be restricted or come with additional charges:

1. Hazardous Materials: Garbage collectors typically do not collect hazardous materials, such as chemicals, paints, solvents, pesticides, batteries, or medical waste. These items require special handling and disposal due to potential health and environmental risks.

2. Construction Debris: Large amounts of construction or remodeling waste, such as concrete, bricks, tiles, drywall, or lumber may not be accepted in regular trash collection. These materials often require separate disposal methods.

3. Large Bulky Items: Some garbage collectors have restrictions on collecting large and bulky items like furniture, mattresses, appliances, or electronics. They may require you to schedule a separate pickup or take these items to a designated disposal facility.

4. Excessive Weight or Volume: There might be limitations on the weight or volume of trash bags. If your bags are too heavy or oversized, the garbage collector may refuse to pick them up or charge an additional fee.

It's essential to check the guidelines of your specific waste management company or contact their customer service to get accurate and up-to-date information on any restrictions, additional charges, or specific policies they have in place. They can provide you with the most accurate information regarding what they accept and any associated costs based on the number of bags or specific waste types.
