Spruce cleaning refill packs are paper-based that are certified 100% plastic-free and home as well as industrial compostable. You can put the packaging in your local council food waste bin by shredding it into tiny pieces or in your home compost. Our compostable packaging meets the EN 13432 compost protocol for biodegradation at ambient temperatures within 6 months. Our packaging will naturally decompose into biomass which can be used to improve soil fertility.
