9. Ventilated Tupperware with Charcoal Filter
If you have mismatched food storage containers cluttering your cabinets, you can easily convert a medium-sized plastic storage container into a highly functional, low-profile compost bin. This option is incredibly lightweight, stackable, and easy to run through the dishwasher for a thorough sanitize.
Select a container that is deep enough to hold a few days’ worth of scraps. Using a utility knife, cut a square or circular opening in the center of the lid. Cut a piece of activated carbon filter sheet that is slightly larger than the opening. Secure the filter over the hole on the top of the lid using water-resistant tape or hot glue around the edges. This design maximizes airflow directly through the filter, ensuring that oxygen reaches the scraps while trapping any escaping odors immediately.
