Yes, the POTTBURRI is biodegradable under natural conditions such as home compost or with the plant buried in the ground. It decomposes into biomass and fertilizer – without permanently leaving microparticles or other pollutants in the earth. No high temperatures are required, as is the case with purely industrially compostable materials, for example. Nature gives everything for the degradation process of the POTTBURRI: moisture, oxygen and the microorganisms that occur in the soil.
