What does "empty their trash and recycle appropriately" mean in this case?

Question

IN THE LUNCHROOM

• Students should follow the instructions of the person in charge. School aides are there to help the students and are to be obeyed and respected.

• Students should be quiet in the lunchroom when given the silent signal.

• Students should wait until their table is called to empty their trash and recycle appropriately

Thanks for your answer.

Does trash also cover the foods left by them uneaten?

Answer 1

There are bins or containers for different 'left overs'. These left overs include the things that you used: Some are paper stuffs. (napkins, paper plates or cups) some are plastic, (knives forks and spoons,) some is soda cans, and some stuff is food leftovers.

Most places have the bins marked. take your stuff and place the different items in the correct bin. Ask another student for help if you have to.

Answer 2

This means students should put their rubbish in the bin except for items that can be recycled. These are to be put in another place.
