Compostable
Breaks down in a composting environment (air + water).
Material capable of decomposition under specified composting conditions. Composting is human-controlled biodegradation with the aim of faster decomposition and agricultural use of the resulting biomass.
To claim “compostable,” packaging must meet qualifying standards, such as those set by the Biodegradable Products Institute (BPI) or the American Society for Testing & Materials (ASTM). Specifying if the package is intended for industrial or home composting facilitates is also required.
Carbon Footprint
