Can a person throw away used schach in the garbage? If so, must it be thrown away in a baG?
Answer:
Used Sechach can be discarded.
However, since it was used for a mitzvah, it should not be disposed of in a degrading way, and it is correct to keep it separate from other garbage if this is possible. Big planks of wood or canes are to a degree separate by definition, and this is sufficient.
Best wishes.
