Dyper wants you to send in your poop – or rather, your baby’s poop. For those who subscribe to the diaper service, Dyper will take back his compostable diapers once the baby has finished his work and arrange composting in his ReDyper program, a partnership with waste management company TerraCycle.   Subscribers receive ReDyper hazmat shipping boxes and labels that go to TerraCycle, which sends them to an industrial composting facility of a partner. Although it is not the only diaper service, Dyper says the product is the first compostable diaper ever made. But it is up to the user to ensure that the diapers are actually composted and not sent to a landfill (where they are not biodegraded) with other waste.   A subscription to Dyper – which delivers between 100 and 260 diapers per week, depending on the baby – costs $ 68 per month. ReDyper will costs $ 39 extra per month. The company says its diapers are made “with viscose fibers from responsibly produced bamboo” that subscribers can compost themselves at commercial facilities.   Dyper says that it purchases CO2 offsets on behalf of Cool Effect customers for every delivery. Dyper CEO Sergio Radovcic said in an email The edge that the company has expansion plans “to limit the further impact of shipping the diapers to and from our composting sites,” adding that “our main goal is to prevent diapers from being thrown to the landfill.”
