elimination

Our rigid shell is made from a blend of recycled and recyclable polypropylene (PP) and natural wheat straw fibers.

At the end of its life, it can be disposed of with household waste.

Under optimal conditions, the material decomposes without leaving harmful residues or producing permanent microplastics.

Since there is currently no large-scale bioplastic collection system in Europe, we recommend this disposal method.

FAQ

Will the case still fit if I use a screen protector or a lens cover?

Yes, our case is designed to be compatible with most standard screen and camera protectors. The raised edges provide extra protection without compromising the fit.

Does the case warp over time, or does it remain stable?

Our hard cases are not made of soft silicone, but of a sturdy, slightly elastic bio-based material. This ensures a precise and consistent fit, without deformation or looseness.

What exactly is the case made of?

The Biowaves case is made from a blend of biodegradable, non-toxic materials that contain recycled components. It contains no plasticizers, BPA, or other controversial additives; it is gentle on the skin and odorless.

Is the envelope truly biodegradable? How does it work?

Yes, this material is designed to break down completely under industrial or natural conditions. This process produces neither microplastics nor residues that are harmful to the environment.

Under ideal conditions, within industrial composting facilities, the decomposition process is particularly effective. Unfortunately, these facilities are not yet widespread in Europe.

How can I dispose of the case once it has reached the end of its useful life?

Although the coating is biodegradable, we recommend disposing of it with household waste.

Why? In many regions, biodegradable materials are sorted as organic waste, much like compostable trash bags.

Even when disposed of with household waste, the material breaks down completely over time thanks to a certified additive, leaving no microplastics behind.

👉 Note: Detailed instructions regarding waste disposal are available on each product page.

Where is the case manufactured?

Our cases are designed in Germany and manufactured in collaboration with Fair Trade-certified partners. This ensures that production, quality, and working conditions meet our sustainability standards.
