The trash compactor so compresses the trash that two to three times as much trash fits in the same size bag. This saves trash storage space, removal time, and disposal labor.
You can put glass bottles and jars into your compactor… but don't put them at the bottom of the bag or near the sides. Otherwise, broken glass could tear the trash bag or injure the person who changes the bag.
Note… If your community has a glass recycling program, it would be better to recycle your glass than to compact it with your trash.
