Unfortunately, our cardboard box packaging for our laundry and dishwasher powdered detergents is not recyclable. The boxes are coated with a plastic layer which is necessary on all powdered detergent and serves as a moisture barrier to protect the powder from humidity and moisture, which can ruin the detergent. This coating used to be on the interior of the dish detergent box, so you may not have noticed it before. Having this coating on the exterior of the packaging helps to protect the box. We're actively looking to develop a better, biodegradable humidity coating and hope to have it nailed down soon!
