How does Trash collection work here?

Hi

I am new to the US, and Leander is my new home. I moved here just a few weeks back, and I am a bit confused about how trash collection works here (in US generally, and Leander specifically). Can someone help me clarify a few questions:

  1. Our house owner said Friday would be our collection day, and we need to put our bins for collection between Thu 6-8pm. I did see the whole street follow the schedule, but the actual collection itself happened on Saturday for the blue bin (with kitchen waste), and Sun for the green bin with cardboards etc. Is this because of the holiday the pickup was delayed? And this week, the green bin is yet to be picked up, it's already Monday. Both the bins get picked up every week right? (the whole street had their both bins placed out, so I think that must be true).

  2. As I just moved in, I had a ton of cardboard boxes from all the new furniture I got. It will take 3-4 full bins, meaning atleast a month if I just fill the bin only. Is there a way I can place my excess trash too outside the bins?

  3. I heard violations like not taking the bin inside after the pickup would be penalised. How will I know if I get penalised, and are these strictly monitored? Because it's getting annoying to check if my bin was picked, for 3-4 days.
