Home Composting Our bags have been certified for home composting and are polyethylene-free, which means they can (when using a proper compost) break down into a material that can be used as part of quality soil in non-consumable gardening.While you can’t use it to fertilize your fruits and vegetables due to the bacteria in pet waste, you can use it on flowers, grass, and more. Learn more here. Composting with Municipal Composting Facilities They are also compostable in select municipal facilities that accept pet waste. However, not all communities have access to such facilities. To ensure a proper send-off, please sniff around your local area for such composting options.
