At the end of its lifespan, the case can be disposed of with regular household waste.
Under suitable conditions, the material decomposes without leaving harmful residues or producing permanent microplastics.
Since there are currently no comprehensive take-back systems for bioplastics in Europe, we recommend this disposal method.

FAQs
Will the case still fit if I use a screen protector or camera lens protector?
Yes, our case is designed to be compatible with most common screen and camera protectors. The raised edges provide additional protection without affecting the fit.
Does the casing stretch out over time or does it remain stable?
Our hard cases are not made of soft silicone, but of a robust bio-based material with slight elasticity. This ensures a consistently precise fit – without stretching or wobbling.
What exactly is the casing made of?
The Biowaves case is made from a biodegradable, pollutant-free material mix with recycled components. It contains no plasticizers, BPA, or other questionable additives and is skin-friendly and odorless.
Is the casing truly biodegradable? How does that work?
Yes – the material was developed to decompose completely under industrial or natural conditions. This process does not produce microplastics or environmentally harmful residues.
Under ideal conditions in industrial composting plants, the decomposition process is particularly efficient. Unfortunately, such plants are not yet widespread in Europe.
How can I dispose of the case when it has reached the end of its useful life?
Even though the casing is biodegradable, we recommend disposing of it with household waste .
Why? In many regions, biodegradable materials are sorted out of organic waste – similar to compostable garbage bags.
Even in household waste, the material decomposes completely over time thanks to a certified additive , without leaving any microplastics.
👉 Note: Detailed disposal instructions can be found on each product page.
Where is the casing manufactured?
Our cases are designed in Germany and manufactured in cooperation with certified, fair-trade partners . This ensures that production, quality, and working conditions meet our sustainability standards.
