There is a citizens drop off area in Sumter County. It's a bit of a drive, about 30 minutes from Lake Sumter Landing. There is a fee charged, but it is a great way to get rid of trash that cannot be put out for normal garbage pick up. It is located at
819 CR 529 Lake Panasoffkee, FL 33538. Here is a link to the web page that shows what they accept and the fee's charged.
