You can compost the bag in your own home composting system or in an industrial composting center (curbside or drop-off). The materials are certified to biodegrade by a minimum of 90% within 12 months - or 6 months if your compost system maintains temperatures above 68 degrees. Before composting the bag, remove the oxygen absorption packet and discard it in the trash. The oxygen absorption packet includes iron powder that should not be composted or recycled.If you plan to compost the bag in your home composting system alongside food scraps and yard waste, we recommend tearing the bag into smaller strips to speed up the biodegradation process. The bag requires typical composting conditions (>40% humidity and temperatures above 68 degrees) to fully decompose, which may require occasional watering and result in minimal progress over cold winter months.
