Enviro needs to be in a high bacteria environment like a commercial compost or an active landfill to degrade. Once there, it completely depends on the size and shape and how solid or hollow the object is. Bracelets were printed and tested for 45 days against standard ABS. In our testing, Enviro would have degraded completely in 12.7 years, and the standard ABS between 800 to 1,000 years. Of course, we can not claim that 12.7 years unless we run the test for that period of time, but that's what the data extrapolates to.
