The compostability of our casings was tested under anaerobic conditions, such as those found in biogas plants or landfills. However, most compostable waste is broken down in composting facilities under aerobic conditions. Under these conditions, the degradation process of our casings could take too long and disrupt the composting process.

The take-back systems in Europe are in almost all cases not yet set up for bioplastics and would sort our cases out as plastic waste.

As long as there are no take-back systems for bioplastics in Europe, the recommendation is to dispose of our mobile phone cases via household waste.
