Let’s start at the beginning. These products began life as limestone waste from quarries. The waste is rescued and, in a revolutionary process that it has taken decades to perfect, turned into packaging. This feat of transformation uses renewable energy, zero water, acid or bleaches while creating zero pollution in a carbon neutral process.
They are designed to be re-used, but at the end of their useful life can be recycled with soft plastics* or with time and sunlight, will just return to the earth as dust.
